Safety
2.3
SAFETY PRECAUTIONS
Review the safety practices listed below. Questions should be resolved before proceeding.
1. Allow only qualified and authorized people to work on electrical equipment. A safety
hazard of great concern is the possible activation of the AIRE-O2® TRITON® during
servicing. Disconnect power at the main power control panel. Be sure to use a lock out
tag.
2. Unless a wire is positively known to be dead, treat it as a live wire.
3. Portable electrical tools should be grounded with a three conductor cord.
4. Do not lift objects too heavy for specific capabilities. Get help or use a hoist or crane.
5. Do not exceed the lifting capacity of a crane or hoist.
6. Designate one person to direct the crane operator.
7. Wear a hard hat when using lifting equipment.
8. Do not stand under any lifting object.
9. To prevent falls, recognize that flotation surfaces may be slippery when wet.
10. Clean up any spills in the work area.
11. Wear a life preserver in area's such as the edges of tanks or when working over water.
12. Never place hands or tools in the air intake holes or near the propeller when the unit is
running or not locked “out of service.”
13. As the treated liquid may be a source of infection, the best defense against infection is
the practice of good personal hygiene and prompt medical attention for any injury that
breaks the skin.
14. Workers should keep their fingers out of the eyes, nose, and mouth.
15. Never smoke or eat while working around waste water.
16. Wear gloves when handling the AIRE-O2® TRITON® propeller to protect yourself from
sharp edges.

2.5
LOCKOUT TAGS
A safety hazard of great concern is the possible activation of the AIRE-O2® TRITON® when
you are servicing it. A minimum precaution is to use “lockout” cards on switching equipment
controlling the AIRE-O2® TRITON® . The best precaution is to lockout the equipment with
some form of key lock.
An example of a “lockout” card is shown. They may be purchased from sign supply houses.
When an AIRE-O2® TRITON® is shut off for service, the card is hung or fastened on the switch
or controller to inform others not to operate the switch. In addition, locking the switch off should
be done if possible.

ASSEMBLY OVERVIEW
New Installation
This section will guide initial assembly of components as received from the factory. After
removing them from their shipping container, examine components for any shipping damage.
Assembly Overview
First, assemble the flotation assembly (see pages 8 - 19). Next, mount the blower to the flotation
assembly (see pages 12 - 19). Very important: Mount the atomizer on the end of the aerator
shaft. Next, mount the AIRE-O2® TRITON®, with atomizer attached to the flotation assembly
(see pages 20 - 26). Flotation assemblies must then be positioned in the water and the motor
electrical cable attached.
Important: Do not fail to install the atomizer (and spindle extenxion 50 - 75HP), which is
shipped unattached to the Triton aerator.

FLOAT ASSEMBLY
Installation
Note: Important!!! Select a level work area. Do not tighten any fasteners until unit is
completely assembled and lined up.
1. Place each float on the ground, spacing them approximately as shown in the dimensional
drawings (pages 8-11).
2. Using assembly drawings (pages 12-19), assemble the cross-arches, cross rails, and
main frame on the pontoons as shown.
3. Place the U-bolts in position on each pontoon. See assembly drawings for location
(pages 12-19).
4. Attach cross rails & arches loosely to main frame. It may be necessary to enlist the
assistance of additional personnel with the five float system.
5. The mount bracket should be positioned on main frame using the lower two sets of
holes. See assembly drawings (pages 12-19) for reference.
6. As indicated in the assembly drawings (pages 12-19), remove and replace the bolt from
each front pontoon with the eyebolts provided. Eye is toward the inside of the pontoon.
Note: Reuse washers and nut from bolt. These eyebolts will be used to attach vortex
shield at final assembly.
Note: Be sure to square the frame before tightening the fasteners. This can be
verified by measuring corner to corner at identical reference points on the frame.
7. After unit is completely assembled and squared, tighten all fasteners.

BLOWER ASSEMBLY
Blower Voltage Options
AIRE-O2® TRITON® blower motors are designed to handle a broad range of world voltages and
power supply variations. Our dual voltage 3 phase motors are factory tested and certified to
operate on both: 200 / 230 / 460 VAC 3 Phase 220 / 380 / 440 VAC 3 Phase 50 Hz. Our dual
voltage 1 phase motors are factory tested and certified to operate on both 104-115 / 208-230
VAC 1 Phase 60 Hz and 100-110 / 200-220 VAC 1 phase 50 Hz. All voltages above can handle
a ±10% voltage fluctuation.
NOTE: For further information regarding AIRE-O2® TRITON® blowers, please contact
Aeration Industries International at the Customer Service Hot-Line ( 1-800-328-8287 ).
Installation Instructions
(Blowers)
THE AIRE-O2® TRITON® blowers HP's are sized depending on the specific AIRE-O2® TRITON®
motor horsepower of the AIRE-O2® TRITON® system.
Bolt It Down
Mount the blower onto the frame assembly. Any blower must be secured against movement
prior to starting or testing to prevent injury or damage. The blower does not vibrate much more
than a standard electric motor.
Air Filter
All blowers should be filtered prior to starting. Care must be taken so that no foreign material
enters the blower. If foreign material does enter the blower, it could cause internal damage or
may exit at extremely high velocity.
Support the Piping
The blower flanges and nozzles are designed as connection points only and are not designed
to be support members.
Wiring
Blowers must be wired and protected/fused, all in accordance with Osha, Local, State and
Federal Regulations. . All blowers must be grounded to prevent electrical shock. Slo-Blo or
time delay fuses should be used to bypass the first second of start-up amperage. (See electrical
assembly pages 58 - 62)
Rotational check
The blower rotation is easiest to verify when the unit has been assembled and has yet
to be put in the lagoon. To verify rotation, disconnect the flexible tube at the housing and
apply power to the blower motor to verify you have air flow.
Warning: If the rotation is incorrect, the pump will pull wastewater up the housing shaft
and into the pump.
Motor Internal Connections
Your first source of wiring information should be the motor nameplate. Some motors will display
wiring information inside the junction box cover. Others may have sheets accompanying the
motor.

AIRE-O2® TRITON® ASSEMBLY PLACEMENT
1. Slide or hoist the AIRE-O2® TRITON® and flotation assembly into the water. To hoist the
assembly, fasten a sling or chain to each main frame rail just to the front of the motor
mount brackets. This is near the balance point for the entire assembly. Lift slowly and
check the balance of the assembly before moving.
2. Once the unit has been placed in the water. Position the AIRE-O2® TRITON® at a 45
degree angle below horizontal. Secure it with four 1/2" x 1 1/2" bolts through each
mount bracket and mounting flange. These bolts will be in the 3 and 9 o'clock positions.
(Horizontal)
3. Move the AIRE-O2® TRITON® to its location on the lagoon.

4.0
MOORING AND MOUNTING OPTIONS
Mooring Options
1. Fasten the AIRE-O2® TRITON® to the Mooring cable using the clamps provided. Leave
the clamps loose until the AIRE-O2® TRITON® system is located in its operating position
in the pond. (Ref. floatation cable attachment drawings pages 37 - 40)
2. Wire the motors using the wiring instructions on the motors and secure the power cables
to the frame and cables with tie wraps. See Electrical Section pages 58 - 62 and
Power Cable Selection pages 64 - 67.
Note: If the span from shore to shore is too great and more then one unit is attached to
span cable, care must be taken in routing electrical cable. The weight of the electrical
cable if attached to the span cable might be too great for the aerator to support. If this
is the case, other means of routing the electrical cable must be used.
The installation of cable float supports, or overhead support cable are options. Routing of the
electrical cable on the bottom of the lagoon can be done if UL approved submersible cable is
used.

4.1
FLOTATION CABLE ATTACHMENT
There are two methods of anchoring AIRE-O2® TRITON® flotation assemblies. The variables
listed below are considered to determine the most practical anchoring method for a given
installation. (See 1-13 below.) They are also used to select wire rope cable size, cable anchors,
power cable size, AIRE-O2® TRITON® positioning, anchor weight, anchor shape, and anchor
position.
VARIABLES:
1. AIRE-O2® TRITON® horsepower
2. Number of AIRE-O2® TRITON® (s)
3. Water depth
4. Water level fluctuation
5. Dimensions of body of water
6. Shape of body of water
7. Wind and wave action
8. Snow and ice loading
9. Embankment or wall height above water surface
10. Continuous or seasonal use
11. Navigation requirements
12. Maintenance considerations
13. AIRE-O2® TRITON® orientation in body of water
Aeration Industries International, lnc., provides technical assistance on sizing and placement
of the AIRE-O2® TRITON® (s). Cabling or anchoring method should be determined before
installation.
4.2
CABLE SAG ALLOWANCE
Cable sag is measured at the midpoint of the longest span length between anchor cable
supports. Supports include cable anchor posts, aeration flotation, and auxiliary flotation. When
installing new anchor cable, sag allowance must be decreased to compensate for in-service
stretch.
The following chart lists sag allowances for span-direct anchor cabling configurations. This is
the minimum sag allowed. Allowing more sag will place less strain or tension on the cable and
its anchors. Under no circumstances should the anchor or power cable allowed to be in the
water.

SPAN DIRECT MOORING
4.3.1 3,4, 5 AND 7 FLOAT
The span direct cabling system will accommodate water level fluctuations up to three feet. To
insure proper slack (cable sag), the span direct cables should be installed with the water at its
lowest level. If this is impractical, then close observation must be maintained as water levels
change to prevent either excessive cable tension or slack.
The standard span-direct cabling attaches the AIRE-O2® TRITON® perpendicular to the cable.
Position the cable along the front cross member and attach it with cable clamps.
Once the AIRE-O2® TRITON® unit has been attached to the span cable, run the appropriate
electrical cable to the AIRE-O2® TRITON®. Attach it to the cable with plastic ties, leaving slack
between each tie.
Note: All four flotation assemblies use the following assembly for Span Direct Mooring

IN-LINE SPAN MOORING
Cable clamps attach the cable to each end of the in-line channel. In certain applications, a
channel iron is fabricated to be used in mounting the cable. The channel iron is bolted to the
flotation frame. The cable is then fastened to the channel using cable clamps. The specific
method used is determined from site factors and is engineered with these factors or requirements
in mind.

START-UP
5.1
ELECTRICAL CHECK
Startup
5.0
WARNING: The main power supply control panel must be a "Power Out Manual Reset"
configuration.
After stoppage of the aerator due to a power outage, voltage spike or any other situation, single
or multiple units must not be allowed to automatically restart, or damage may occur. The
aerators must be either manually bumped and restarted as specified under the start-up section
of the O&M manual or a control panel must be supplied using technology similar to a soft start.
Failure to follow this procedure will void the factory warranty.
WARNING: Do not splice power cable or use quick disconnects between the motor and
the power supply cable at the motor or any other place.
WARNING: Always wear an approved life vest when working on the aerator near or over
water.
1. Install electrical cable onto the span-direct or in-line mount using plastic wire-ties. Space
the wire-ties to limit electrical cable sag between attachments to 2 inches maximum.
Excessive sag may allow the cable to oscillate continuously in strong winds leading to
wear damage.
WARNING: Keep cables off of walkways if provided.
2. Install the electric cable between the span-cable and the motor junction box along a
convenient frame component using wire ties for span-direct or in-line mounts.
3. Electrical cable connection to motor must be completed by a certified electrician using
the wiring diagram provided by the motor manufacturer. Failures due to improper
electrical connection are not covered by the warranty.
4. Electrical cable should not be placed over the sharp edges of the metal frame. Machine
vibration and movement due to wind or wave action will cause abrasion to the cable
insulation.
5. Mounting of the power cable should prevent any tension on any component. This applies
at all points from motor controller to motor junction box.
Use of flexible electrical cable permits easy installation. It allows the AIRE-O2® TRITON® to be
tilted-up for maintenance. Properly installed power cable should not be subjected to constant
flexing due to wind or wave action. This will assure its long life.
A qualified electrician is to check and record voltage supplied to the operating motor upon startup. (See Start-Up Procedure in this manual.)
55
Startup
5.2
MOTOR INTERNAL CONNECTIONS
Your first source of wiring information should be the motor nameplate. Some motors will display
wiring information inside the junction box cover. Others may have sheets accompanying the
motor. Another source of wiring diagrams are found in the motor wiring diagrams in this manual.
Remove the cover of the motor junction box. The numbered wire lead ends will be identified.
5.3
START-UP PROCEDURE
Prior to start-up, electrical power connections should be completed. The AIRE-O2® TRITON®
should be positioned in the water secured by cabling or other means. The propeller should be
free and clear of any obstruction. Keep in mind that once the AIRE-O2® TRITON® is started,
thrust generated will move the AIRE-O2® TRITON® in the water. The distance it will move
depends on cable tension and sag allowance.
WARNING: The AIRE-O2® TRITON® will move or surge when first turned on. No one
should be near the unit or in the water when the machine is turned on or while it is
running.
CAUTION: The AIRE-O2® TRITON® will move when first turned on. This surge or motion
is the result of the thrust created by the unit. All anchoring hardware and/or cabling
should be firmly fastened. Personnel should be clear of the AIRE-O2® TRITON® and its
propeller.
NOTE: Never run the AIRE-O2® TRITON® out of the water. The lower bearing is water
lubricated and will overheat without water lubrication. This may cause severe damage
to the bearing and sleeve. This kind of damage is not covered by the warranty.
5.4
ROTATION CHECK
Once the AIRE-O2® TRITON® (s) is anchored securely in position and all the electrical
connections are checked for correctness, the AIRE-O2® TRITON® (s) are ready for a rotation
test. Check each AIRE-O2® TRITON® individually.
1. Use two people. One operates the ON/OFF switches. Turn on for less than one
second ). The other person observes the AIRE-O2® TRITON® water flow.
CAUTION: Do not operate the AIRE-O2® TRITON® motor in reverse rotation.
2. When visually checking the water flow of the AIRE-O2® TRITON®. The water flow is
the same as a boat with a motor. With correct operation the water/air mixture flows
smoothly away from the unit. Water should not splash up toward the motor end of the
unit.
3. If the rotation is wrong, switch or reverse any two of the three power leads in the motor
starter or at the motor junction box (three-phase). Single phase motors are reversed by
reversing connection of the starter winding leads inside the motor junction box. Most
motors have a wiring diagram for reference printed inside the motor junction box cover.
56
5.5
FUNCTIONAL ELECTRICAL CHECK
Startup
Verify the amperage and voltage for each AIRE-O2® TRITON® at the motor control box. The
motor should be running at this time. This check should be made only by qualified people.
I.
The amperage and voltage readings should be equal to or less than the rating on the
motor nameplate.
2. The voltage supply should read approximately the same on all three leads (three phase).
Keep a record of both current and voltage readings. (Use sheets provided in the
Appendix of this manual.)
These initial readings will provide a reference for comparing with future readings. Any
significant change would signal a problem with the motor, propeller or bearing assembly.
5.6
OPERATIONAL CHECK
1. The AIRE-O2® TRITON® should run smoothly and quietly. Consult the troubleshooting
guide if noise is excessive.
2. Check for vortexes above the propeller. The vortex shield may need repositioning to
eliminate all vortexing. Allowing vortexing to continue may damage the propeller from
cavitation.
After the unit runs several minutes, note the operating position of the AIRE-O2® TRITON® unit.
The AIRE-O2® TRITON® may have to be repositioned on the cables to point it in the optimum
direction. Refer to the AIRE-O2® TRITON® placement drawings provided by Aeration Industries
international or the consulting engineer to reference the installation drawing or arrangement.
IMPORTANT: Because of the various environments that the aerator can be subjected to,
adjustments in the frequency of inspections will vary. Aeration Industries international
Inc. recommends that each aerator is disassembled for thorough inspection of parts at
least once a year.
Required Maintenance Summary
• Grease motor bearings.
• Grease the drive shaft U-joint once a year when disassembling for inspection.
• Inspect and clean debris out of the housing and water lubrication holes.
• Inspect the sleeve, lower bearing, propeller, and drive shaft for wear and debris.
Replace if required.
• Confirm the propeller and atomizer assembly are tightly seated.
• Confirm all fasteners to the aerator, motor and pontoons assembly are secured.
• Inspect electrical and mooring cables for improper sag and wear. Correct as required.
• Confirm all fasteners to all electrical cables are properly secured.
• Monitor and compare voltage and current readings to start-up readings.
• Clear any debris from the motor breather drain / weep hole.
• Inspect for damaged or missing parts.
• Check for proper tension on the motor cord-grip.

Maintenance And Service Schedule
The maintenance record sheet follows on page 42. Make copies and use them to insure
documentation and performance of maintenance procedures. File for a maintenance record.
Honoring any warranty claim will require these signed, dated, and completed sheets as
evidence of proper maintenance.
Daily Observations
Aeration Industries International, Inc., recommends when possible that each unit be observed
daily. The AIRE-O2® TRITON® should run quietly without excessive vibration. Also note the flow
of water and air from the AIRE-O2® TRITON®. Noise, vibration, and disrupted air or water flow
are indicators of operational problems. Daily observation will ensure that problems will be
corrected before damage can occur to the AIRE-O2® TRITON®.
Quarterly Inspection
The record sheets on page 48 should be copied for use during scheduled maintenance of the
AIRE-O2® TRITON® throughout each year of service. Keep the completed sheets on file as a
record of maintenance performed. Copy or reproduce one sheet for each AIRE-O2® TRITON®
for each year of service.
Perform inspection and maintenance at 3, 6, 9, and 12 month intervals. The date of service and
the name of the servicing person should be recorded.
Assign a number to each AIRE-O2® TRITON® and note its location in the lagoon or basin. This
number is used to specify each individual AIRE-O2® TRITON®. Record any changes in location
if needed.
Yearly Inspection
Aeration Industries International Inc. recommends disassembly of the AIRE-O2® TRITON® at
least once a year for universal U-joint lubrication and to visually inspect bearings, sleeve and
shaft for wear or damage.
NOTE: Disassembly and Assembly instructions are covered in the "Service Addendum"
starting on page 74.
Blower Preventive Maintenance

AIRE-O2® TRITON® SERVICE PROCEDURES
7.1
AIRE-O2® TRITON® SERVICE
The AIRE-O2® TRITON® shaft-housing assembly may be removed for servicing without the
need for removing the heavy motor. This permits leaving the AIRE-O2® TRITON® installation in
place, simplifying routine maintenance. AIRE-O2® TRITON® (s) may be pivoted raising the
propeller out of the water so that inspection, lubrication, and repairs can be made. If motor repair
or replacement is to be performed, then a hoist will be needed. A boat will be needed to service
AIRE-O2® TRITON® (s) mounted on floats.
NOTE: Disassembly and Assembly instructions are covered in the "Service Addendum"
starting on page 74.
DANGER: Turn off electrical power and lock the AIRE-O2® TRITON® “out of service”
before servicing . Use lock-Out Cards.
1. Turn the motor off and lock the unit out of service.
2. Approach the AIRE-O2® TRITON® (using the boat) to reach the motor mounting
brackets. Disconnect the vortex shield to take it out of the way.
3. Loosen the four mounting bolts, permitting the AIRE-O2® TRITON® to tip to a nearly
horizontal position. This lifts the propeller and housing assembly out of the water. Lock
the motor assembly in the nearly horizontal position by replacing a bolt and nut through
the mount bracket slot and a hole in the mounting flange.
4. Move the boat around the AIRE-O2® TRITON® flotation to approach the propeller end
with the rear of the boat. Position the boat between the pontoons and under the AIREO2® TRITON®, Inspect the AIRE-O2® TRITON®. The points listed may be followed in any
order. The specific items checked will prevent problems and extend service life.
7.2
INSPECT THE AIRE-O2® TRITON®
1. Check the bolts on the housing and motor mounting flange and retighten.
2. Look for any signs of corrosion.
3. Check the flotation unit for any loose bolts, parts, or damage. Correct as necessary.
4. The propeller and atomizer should be free of debris.
5. Closely examine the propeller and diffuser for indication of wear Slight propeller wear
grooves are acceptable if the profile or shape of the propeller blade is not affected.
Should wear be extensive, replace the worn item.
6. Remove any debris obstructing the bearing water lubrication holes. These holes are
locatedin the lower end of the housing just above the propeller.
7. Visually inspect the bearing for wear. Wear groves should be visible and even. Replace
the bearing and sleeve if the wear groves are gone or uneven wear is evident replace
the bearing.
64
Note: Replace the sleeve if it is showing any wear.
Maintenance
8. Manually turn the shaft. The sleeve should rotate with the shaft. Keeping the propeller
tight will hold the sleeve to the shaft. If the sleeve slips on the shaft it must be replaced
to prevent further damage to the shaft.
9. To properly inspect the sleeve both the atomizer and power mix propellers must be
removed. Remove the nylon washer and slide the sleeve off the shaft. The sleeve must
be replaced to prevent additional damage if there are groves, ships or signs of cracking.
Note: The sleeve must rotate with the drive shaft
10. The hollow shaft should be open and free of debris.
11. Attach a rat tail (bottle) brush to a rod. Use it to clean the interior of the shaft. Be sure
the brush reaches to the air intake holes.
12. Manually turn the shaft. It should turn freely. If it does not, check the motor bearings and
elastomeric bearings (surrounding the sleeve) for binding. (See "Problem Analysis"
pages 54-57.)
13. Lubricate the grease zerk fitting at the universal joint. Access to the zerk fitting is attained
by removing the atomizer, power mix propeller and the four bolts that hold the housing
to the mounting flange. Slide the housing away from the motor to expose the universal
joint. Grease and reassemble.
NOTE: See lubrication instructions on Page 52)
14. Examine electrical cable, cable mounting, and connections. If insulation is damaged,
repair the damage or replace the cable, All fastenings should be secure.
( Do not under any circumstances splice the power cable.)
15. The positioning or securing of the wire rope cable should be in satisfactory condition with
clamps or mounting devices properly tightened.
Once the above checks have been completed, the AIRE-O2® TRITON® motor should be
positioned as it was before Steps 3 and 4. Tighten bolts securely.

Maintenance
7.3
LUBRICATION
An adequate procedure and schedule of bearing lubrication is necessary to prolong bearing life
yet prevent motor damage from over greasing.
The motor manufacturer's standard recommendation are that all motors should be greased
every 3 months
The motor should be warm and should have been operating at least 20 minutes immediately
prior to lubrication.
Examine the motor to determine the procedure to be used. Where Alemite or zerk fittings are
provided, clean the fittings. Insert the lubrication fitting on the motors provided with plugs.
Remove both upper and lower grease relief plugs before greasing. Check for hardened grease
by inserting a wire into the grease relief tube to clean it. Evidence of hardening or waxy grease
would require through cleaning of the tube.
Grease both the upper and lower bearings of the motor. Use a limited amount of lithium based
grease.
WARNINGS:
-
Do not pump grease through the bearing to "Flush" it out. Excessive greasing is
detrimental to motor life.
The motor should be "Off" when greasing or performing other maintenance.
After greasing, run the motor one hour before replacing the relief plugs. This allows excess
grease to be purged or any pressure build-up to be relieved.
U- Joint Lubrication
Lubricate the grease zerk fitting once a year when the unit is disassembled for inspection.

THREE PHASE MOTOR CONNECTIONS
Wound coil ends terminating in the motor junction box are identified as T1, T2, T3, T4, etc. You
will find 3, 6, 9, or 12 of these leads.
L1, L2, and L3 identify 3 - phase line connecting points.
Reversing motor rotation on 3 - phase motors involves interchanging any two of the three power
leads, L1, L2, or L3.
A small triangle may be used to indicate Delta winding connections. Y connections may be
called “star-” or “wye” The following configurations apply to both 50 Hz and 60 Hz motors.
3 LEADS
Motors with 3 leads (T1, T2, T3) are connected directly to LI, L2, and L3 in any order. Reversing
any two of the three leads will reverse the rotation of the motor.

POWER CABLE SELECTION
10.1
POWER CABLE SIZE/LENGTH SELECTION OVERVIEW
Power Cable Selection
10.0
The following charts will aid in determining the power cable conductor size for a given
horsepower and installation distance.
In the interest of long motor life, it is recommended that voltage drop between the motor
controller and the motor be less than 2% of the motor nameplate voltage. This design criterion
is particularly important where motors are to operate reliably under high ambient temperature
and “brown out” voltage conditions.
The recommendations are based upon information obtained from the 2002 National Electric
Code (NEC).
Certain installations may pose unusual design problems. Consult with Aeration Industries
International, Inc. before committing to designs that may compromise motor life.
NOTE: AIRE-O2® TRITON® blower motors are designed to handle a broad range of world
voltages and power supply variations. Our dual voltage 3 phase motors are factory
tested and certified to operate on both: 200 / 230 / 460 VAC 3 Phase 220 / 380 / 440 VAC
3 Phase 50 Hz. Our dual voltage 1 phase motors are factory tested and certified to operate
on both 104-115 / 208-230 VAC 1 Phase 60 Hz and 100-110 / 200-220 VAC 1 phase 50 Hz.
All voltages above can handle a ±10% voltage fluctuation.

Cable length calculations are based on 125% motor full-load amperage (FLA), NEC Article 430-22 (A).
For special motors wired for Wye-Start, Delta-Run, the selection of conductors between the controller and the motor may be based on 58
percent of the motor full-load currrent [NEC 430.22 (C)]. It is recommended that the contractor/electrician contact Aeration Industries for

Allowable Ampacities, obtained from NEC Table 310-16, Ampacities of Insulated Conductors - Copper Conductor at 75o C, “——” indicates inadequate Ampacity.
NOTE: Length calculations are based on resistance values obtained from NEC Table 9, AC Resistance and Reactance for 600 VAC Cables, 3 Phase, 60 Hz, 75o
C (167o F). Typically the power cable is sized using the distance between the junction box on the shore and the motor, this being refered to as the "hard wire" connection.
The power cable between the junction box and the controller is then sized separately using this new distance. This is especially critical where there is a great distance
to a central control station and a heavier gage wire is required.

STORAGE PROCEDURES
Storage
In case of outdoor storage, the motor must be covered with plastic without sealing it. Otherwise,
condensation will occur, which can cause motor damage.
If the units are left in the water, put a plastic cover securely over the motor without sealing it.
To prevent condensation on the windings when the motors are stopped for a long time, motor
space heaters are required.
Storage Conditions
Short Term
The following storage requirements must be followed:
1. Motors are to be kept in their original containers or provided with equivalent protection
and stored in a warehouse free from extremes in temperature, humidity, and corrosive
atmosphere.
2.
If unusual vibrations exist at the storage location, the motor should be protected with
isolation pads.
3. All breathers and drains are to be operable while in storage and/or the moisture drain
plugs removed. The motors must be stored so the drain is at the lowest point.
Storage Preparation
Improper storage of electric machines will result in seriously reduced reliability of that
equipment. For example, and electric motor that does not experience regular usage while being
exposed to normally humid atmospheric conditions is likely to cause the bearings to rust or rust
particles from surrounding surfaces to contaminate the bearings, The electrical insulation may
absorb and excessive amount of moisture leading to the motor winding failing to ground. The
following preparations should be followed:
1. Minimize condensation in and around the motor by use of desiccants or other humidity
control methods.
2. Motor space heaters when specified are to be energized where there is a possibility that
the storage ambient conditions will reach dew point. Space heaters are an option.
3. Coat all external machined surfaces with a material to prevent corrosion. An acceptable
product for this purpose is Exxon Rust Ban #392.
4. Measure and record the electrical resistance of the winding insulation with a megger or
an insulation resistance meter. Minimum accepted Megohm Level is the insulation kV
rating +l Megohm. If levels fall below the above, contact the nearest Reliance sales
office. The recorded data will be required when removing from storage.
5. Some motors have a shipping brace attached to the shaft to prevent damage during
transportation. The shipping brace, if provided, must be removed and stored for future
use. The brace must be reinstalled to hold shaft firmly in place against the bearing
before the motor is moved.

STORAGE PROCEDURES
Storage
6. Upon placing the motor into extended storage (greater than 3 months), the motors with
greaseable bearings must be greased per Table 1 on page 72, followed by the motor
shaft being rotated a minimum of 15 times after greasing. Non-greaseable motors with
“Do not Lubricate” nameplates should also be rotated 15 times to redistribute grease
within bearing.
7. Motor shafts are to be rotated manually every 6 months and additional grease added
purging some of that cavity. Grease in the bearings is to be purged at the time of
removal from storage, making sure that an ample supply of fresh grease is in each
grease cavity.
8. Remove the grease drain plug, if supplied, (opposite the grease fitting) on bottom of
each end bracket prior to lubricating the motor.) Replace the plug after greasing.
Non-greaseable motors should have their shaft rotated 15 revolutions every 3 months.
9. All breather drains should be fully operable while in storage. The motors must be stored
so the drain is at the lowest point. All breathers and automatic “T” drains must be
operable to allow breathing at points other than through the
bearing fits.
10. The space heaters when specified are to be connected and operable while in storage.
11. Windings are to be meggered at the time equipment is put in storage. At the time of
removal from storage, the insulation resistance reading must not have dropped more
than 50% from the initial reading. Any drop below this point necessitates electrical or
mechanical drying. Refer to “Motor Drying Procedure.”
12. Where motors are not stored in the original containers, but are removed and mounted
on other pieces of machinery, the mounting must be such that the drains and breathers
and space heaters are fully operable. In thisrespect, the drains must be kept at the
lowest point in the motor so that all condensation can automatically drain out.
For Storage of Extended Periods of Time
Greater than 18 months
All requirements of general preparation and short term storage apply with the following
additional requirements.
1. Motor is to be crated in a box similar to EXPORT BOXING but that the “shell” (sides &
top of box) will be LAG- BOLTED to the wooden base (not nailed as export boxes are).
This design will allow for the opening and re-closing the box many times without
destroying the “shell”.
2. The motor will be sealed in an airtight vapor barrier bag with desiccant inside. This
airtight bag will give added protection during shipment of motor to the permanent
storage area.
3. After the first “Inspection” for megger reading, turning the shaft, etc., the vapor bag
should be re-sealed by taping it closed with masking or similar tape. Also add new
desiccant inside bag before closing. The shell should then be placed over the motor and

the lag bolts replaced.
4. If a “zipper-closing” type bag is used instead of the “heated-sealed” type bag, then rezipper the bag closed Instead of taping it.
5. Be sure to add new desiccant inside bag after each periodic inspection.
6. Minimize the accumulation of condensed water in and around the machine.

AIRE-O2® TRITON® DISASSEMBLY AND REASSEMBLY
DANGER: Turn off electrical power and Iock the aerator “Out of Service “ before working
on the aerator. A hoist will be needed if the motor will be replaced. Otherwise servicing
and repairs can be preformed after tipping the unit up raising the propeller above the
water. Lock in place using bolts.
Propeller and Diffuser Disassembly: (Ref: Drawing on page 76)
1. Slip a large screwdriver through the air intake hole in the housing and into the shaft
universal joint, to prevent the shaft from turning. Take care not to damage the grease
zerk in the universal joint.
2. Remove the two (2) set screws from the diffuser (atomizer).
3. Using a wrench, loosen the diffuser, screw the diffuser off in a counter clockwise
direction.
4. To remove the propeller tap the propeller with the rubber mallet and unscrew the
propeller in a counterclockwise direction.
CAUTION: Always wear gloves when handling the propeller. Blade edges may be sharp.
Housing Disassembly:
Remove the housing by unscrewing the four cap screws attaching the housing to the motor
mounting flange. Slide or pry the housing off the shaft.
NOTE: The sleeve may remain in the bearing and come off with the housing. Take care
not to drop the sleeve as it may shatter.
Sleeve Removal:
Slip the sleeve and the two nylon washers off the shaft. Remember, the sleeve will crack or
shatter if dropped.
Shaft Disassembly:
Loosen the two Universal joint set screws holding the aerator shaft to the motor shaft. Slide the
aerator shaft off the motor shaft. Remove the key. Aerator parts can be serviced if needed.
Bearing Removal:
The bearing can be removed from the housing by pressing’ it all the way through from the
propeller end, letting it fall out the flange end of the housing. Scrape off any bearing residue
that may stick to the housing bore.
Another method is to hammer a screwdriver along the inside diameter of the bearing. Once the
black elastomeric portion of the bearing has been split, wedge the screwdriver between the fiber
backing and the housing bore at the point of split. The bearing will crack and can be peeled out.
Scrape off any bearing residue that may stick to the housing bore.

1. Stand the shaft housing vertically, with flange end down, and insert a new bearing into
the prop end of the housing. Place a fiat protective plate over the outside face of the
bearing. Press or pound on the protective plate until the bearing is installed flush with
the face of the housing.
2. Using the three existing holes located in the propeller end of the housing as guides,
match drill holes completely through the bearing. Remove any material shreds
remaining around the newly drilled holes. Use a sharp knife to do this trimming. Bevel
the internal opening. Cut away bearing burrs or shreds to smooth opening.
Mounting Flange And Shaft Assembly:
1. If the mounting flange has been removed, reattach the mounting flange to the motor
using four cap screws and washers. Viewing the motor from the shaft end, with the
electrical junction box at 12 o’clock, orient the pins on the mounting flange in the 9 and
3 o’clock positions.
2. Insert the key into the motor shaft and coat the shaft, key way, and the key liberally with
anti-seize compound.
3. Slide the aerator shaft Universal joint onto the motor shaft until it contacts the shaft
shoulder. It may require tapping with a rubber hammer.
4. Apply anti-seize compound to the two Universal joint setscrews. Tighten the setscrew
over the key first to ensure proper balance of the shaft. Tighten the remaining set screw.
Housing Assembly:
1. Slip the shaft housing, flange end first, over the aerator shaft, bolt it to the motor
mounting flange. Use four cap screws and lock washers.
NOTE: The air intake hole should be in the up position, in line with the motor electrical
box.
Sleeve Assembly:
1. Slide a nylon washer onto the aerator shaft. Apply a grease lubricant to the outer surface
of the sleeve, and slide the sleeve over the protruding shaft end. Insert the sleeve
through the housing bearing until it contacts the shaft shoulder.
2. Slide the remaining nylon washer onto the shaft into place against the sleeve.
Propeller And Diffuser Assembly:
1. Insert a large screwdriver through the air intake hole in the housing and into the shaft
Universal joint to prevent the shaft from turning. Do not damage the grease zerk in the
Universal joint.
2. Inspect the propeller inside bore and threads. Inspect the shaft area protruding from the
housing, and the threads. Remove dirt or debris.
3. Liberally apply anti-seize compound to the entire shaft area protruding from the housing
including the threads and slide the propeller onto the shaft.
