WARRANTY
All covered components − Limited five year warranty
in residential applications, one year in non-residential
applications.
Refer to Equipment Limited Warranty certificate
included with equipment for details.
APPROVALS
All units are E.T.L. Listed.
Energy Star® certified unit (CCWH-065 model only) is
designed to use less energy, help save money on utility
bills, and help protect the environment.
APPLICATIONS
The Complete Comfort™ Whole Home Dehumidifier is
designed to control humidity throughout the home or
in specific locations such as an attic or basement. Also
used for air cycling and ventilation control.
CCWH-090 and CCWH-135 models are equipped
with a humidity sensor that automatically and
continually measures the relative humidity. Based on
that measurement, the unit will operate to control the
humidity based on the set point.
CCWH-090 and CCWH-135 models feature a built-in,
automatic air cycling feature can be utilized to activate
the furnace/air handler blower to cycle air throughout
the whole home for proper balance and comfort.
CCWH-090 and CCWH-135 models feature a patented,
built-in ventilation feature allows fresh air to be brought
into the home from the outside. The dehumidifier will
condition the incoming air, if needed.
FEATURES
Filter
Includes washable, MERV 8 (Minimum Efficiency
Reporting Value) filter.
Blower
CCWH-065 Model
Blower assembly is a UL approved impeller type
with backward curved centrifugal fan equipped with
maintenance free ball bearings.
CCWH-090-135 Models
Blower assembly includes shaded-pole, heavy-duty,
direct drive blower and blower wheel.
Operates during both ventilation and dehumidification
modes.
Compressor
R-410A, rotary-type compressor.
Cabinet
Constructed of 22 gauge, pre-painted steel.
Interior is lined with 1 in., foil-faced, expanded
polystyrene to eliminate noise, condensation and air
loss.
Duct start collars are included.
CCWH-065 only - Supply collar can be relocated from
the end of the cabinet to the top if space is restricted
The supply outlet is equipped with a built-in backflow
damper.
Adjustable feet (-065 model up to 4 in., -090-135
models - up to 3 in.) to level unit.
If the dehumidifier is installed in an attic or location
requiring leak protection, the unit should be placed in a
secondary condensate drain pan with a normally closed
condensate overflow safety switch (float switch).

Controls
CCWH-065 Model
Dehumidistat is furnished and factory installed on the
unit cabinet inlet panel. It can be easily removed for
relocation to another area within the living space.
The dehumidistat continually measures the humidity in
the air to control the dryness level set on the dial.
Terminal strip for connections of HVAC equipment,
furnace or air handler and float switch.
When connected to HVAC equipment the dehumidifier
automatically controls indoor blower operation during
dehumidification operation.
Two on-board LED’s provides instant status of
operation and maintenance required.
Power is applied to system - Green
Service Required - Red
Three internal, amber LED’s provide status of
dehumidifier impeller (DEH), compressor (COMPR)
and indoor unit blower (HVAC) (if applicable). Viewable
when the dehumidifier cover is removed.
CCWH-090-135 Models
Factory installed control handles operation of unit.
Terminal strip for connections of furnace/air handler,
float switch, ventilation dampers, outdoor air sensor,
and optional Whole-Home Dehumidistat.
DIP switches are used to configure system set (whole
house, zoned or combination system) and ventilation
times (30, 60, 90 or 120 minutes).
DIP switches are used to configure ventilation cycle
periods (1/2, 1, 2, or 3 hours) and a knob for configuring
cycle times (from 0 to 60 minutes).
Knob on the front of the unit sets the desired humidity
level.
On-board humidity sensing allows for better whole
home monitoring and control of humidity.
Optional remote Whole-Home Dehumidistat can be
used to provide easy humidity control accessibility.
On-board LED provides instant status of operation and
maintenance required.
Normal Operation – Green
Air Sampling or Defrosting – Flashing Green
Service Required – Flashing Red
When equipped with overflow safety switch (field
provided and installed), the dehumidifier will continue
to ventilate but the compressor is disabled when the
switch is open.
FEATURES
REQUIRED COMPONENTS
(-065 MODEL ONLY)
Drain Pan
Required if unit is installed in an attic or location
requiring leak protection.
(-090, -135 MODELS ONLY)
Backflow Damper
Constructed of rolled galvanized steel with stiffening
ribs to maintain rigidity. A single steel offset blade is
attached to a one piece aluminium shaft connected
with nylon bearings for smooth operation. Spring return,
normally closed, power open. Requires 24V transformer
ordered separately.
Transformer
120V primary, 24V secondary, 40VA transformer for
powering backflow damper.
OPTIONAL ACCESSORIES
OPTIONS (-090, -135 MODELS ONLY)
Whole-Home Dehumidistat
Whole-Home Dehumidistat is
used to control the dehumidifier
if the unit is installed in a
difficult to access location such
as an attic or crawl space.
Provides an accessible means
of turning the dehumidifier on
and off and allows for adjustment of the humidity level
set point.
Control contains its own sensors that override the
dehumidifier’s main control board sensors.
Basement Kit
Includes components typically needed for basement
dehumidification application.
Includes two 8-in. normally open dampers, two
8-in. normally closed dampers and one 24V, 40VA
transformer.
Ventilation and Zone Dampers
Constructed of rolled galvanized steel with stiffening
ribs to maintain rigidity. A single steel offset blade is
attached to a one piece aluminium shaft connected with
nylon bearings for smooth operation. Spring return with
a normally closed or normally open configurations are
available.Requires 24V transformer ordered separately.
Transformer
120V primary, 24V secondary, 40VA transformer for
powering dampers.
Outdoor Air Temperature Sensor
Prevents the CCWH from using outside air for
ventilation if the outdoor temperature is above 100°F or
below 0°F.
Ventilation (-090-135 MODELS ONLY)
The built-in ventilation feature is designed to be meet
ASHRAE 62.2 Standard for Ventilation.
Utilizes the dehumidifier and furnace/air handler blower
to make-up any remaining ventilation required based on
chosen set point.
In hot, humid climates, supplemental dehumidification
of fresh air is recommended.
Automatically monitors and controls the humidity of
the incoming air. The dehumidifier can also operate an
optional ventilation damper to bring air in from outside.
To keep it from using outdoor air above 100°F or below
0°F, an optional Outdoor Temperature Sensor must be
field installed.
Air Cycling (-090-135 MODELS ONLY)
An integrated air cycling feature can activate the
furnace/air handler blower to cycle air through the
house to balance the indoor air conditions.
Monitors furnace/air handler blower run-time to
efficiently ventilate the whole home,
Air cycling will cycle furnace/air handler blower to the
values set on the control.

SIZING GUIDELINES
1. Find the home location (and corresponding region) in the map below
2. Estimate the air change rate of the home:
a. 1.00 air change per hour is an older home, that is not particularly tight.
b. 0.50 air change per hour is a reasonably tight home.
c. 0.35 air change per hour is a very tight home, typical of new home construction.
3. Determine how many dehumidifiers are required by comparing the actual home size and corresponding
air change rate, to the “Maximum Recommended Home Size” in the table.
4. This is a general guideline. Consider any special circumstances that may require more water removal
capacity and, if necessary, adjust your dehumidifier choice(s) accordingly.
