independently of refrigeration unit(s) for 31/2 minutes out of every 36 minutes. The temperature
control will operate agitator(s) and refrigeration unit(s) whenever cooling is required.
Subsequent Milkings
1.
Just prior to milking, turn agitator timer to a delayed start position. Agitator(s) will not run for
approximately 10 minutes. The agitator(s) will then start and run for approximately 31/2 minutes
blending warm and cold milk. During this period, warm milk entering cooler will cause the
refrigeration unit(s) to start. Agitator(s) and refrigeration unit(s) will continue to run until milk is
cooled to the temperature control setting.
2.
Leave selector switch in “COOL” position.
Butterfat Sampling
1.
After pick-up tank truck driver records the temperature and amount of milk in the cooler, he will
want to agitate milk for a butterfat sample.
2.
To agitate milk for a sample, turn agitator timer knob clockwise to “ON” position while selector is
in “COOL” position. The agitator will run for approximately 31/2 minutes before shutting off
automatically. Agitation can be halted by advancing timer knob. Coolers smaller than 1,600 gallons
should be agitated through two time cycles. Agitate 1,600-gallon and larger coolers through three
time cycles.
26
5.5
5.6
External Measuring Gauge
1.
After determining milk volume, close milk outlet valve on cooler.
2.
Disconnect hose from fitting on outlet valve and dispose of milk that drains from hose and tube.
3.
Remove hex nut and quick-connect tube coupling from outlet valve and place in wash vat for
hand cleaning.
4.
If gauge is used between milkings and cooler will not be washed immediately, close outlet valve
and dispose of milk in gauge tube. Properly clean and sanitize the gauge tube by disconnecting
hoses from cooler and flushing from the top to remove milk residue. Then, reconnect the hoses.
Emptying Cooler
The following steps must be taken before pumping milk out of the cooler:
1.
!
IMPORTANT: Be sure vent assembly is over milk inlet opening and release hold-down clamps on
manhole cover to provide additional venting. To equalize pressure inside and outside of cooler during
filling, emptying, and washing, it is mandatory that vent assembly be kept on the inlet at all times.
2.
5.7
Move selector switch on control cabinet to “OFF” position.
Empty cooler and rinse out remaining milk solids with tepid water.
Washing Cooler
After cooler has been emptied, it should be washed in the following manner:
1.
Remove the nut and locking cap from the outlet valve. Remove the pump suction hose from the
hanger and attach to the outlet valve. If the milk cooler is equipped with an external gauge,
connect the external gauge quick connect to the pump discharge quick connect.
2.
To wash external gauge tube with Mueller Matic, connect lower gauge hose to fitting located
above and to the right of the outlet. Be sure upper hose is connected to fitting on top of cooler.
3.
Be sure the vent assembly is properly installed to equalize pressure inside and outside of cooler
during washing.
4.
Remove the dispenser bowl labeled “Detergent,” discard its contents, and rinse the bowl. Add the
proper amount of detergent recommended for the brand used. The concentration should be based
on the gallons of wash water shown in Table 2, “Water Consumption Chart.”
HAZARD: Never mix chlorinated sanitizers or detergent with acid. Be sure that there is no
previous product residue in the bowl before adding acid.
5.
Move selector switch on control cabinet to “WASH” position and turn Mueller Matic timer knob to
first rinse (clockwise only) to automatically start system. The Mueller Matic will pre-rinse, wash,
rinse, and acid rinse, then turn off automatically.
6.
Sanitizing should be done immediately before milking according to procedures outlined under
Section 5.1, “First Milking.”
7.
If the Mueller Matic does not operate properly, consult Section 6.6, the troubleshooting chart.
27
SECTION 6.0 - GENERAL MAINTENANCE INSTRUCTIONS

This cooler is designed for use with a Mueller cooling control and wash system.
Working Pressure PSI
This cooler is designed for every-day or every-other-day pickup. The maximum rate at which milk can
enter the cooler and meet the cooling requirements of the 3-A Sanitary Standards for Farm Milk Cooling and Holding Tanks, Serial Number
13-10, is
U.S. gallons per hour for every-day pickup and
U.S. gallons per hour for every-other-day
pickup. When milk enters the cooler at the maximum rate, the minimum condensing unit capacity is
Btu/hr at
°F saturated suction temperature. The agitator of this cooler is designed that it must be in continuous operation
minutes before removing a product sample. The agitator of this tank is designed so that the portion of the
agitator shaft outside of the farm tank does not have to be in the milk room when used with an external weather shield.
NUMBER 13-10
Note: The cooling performance specified above is based upon use of the largest condensing unit recommended for this cooler.
Smaller condensing units may be used, but at reduced fill rates. Contact your Mueller dealer for assistance in condensing unit sizing.
