The dehumidifier is supplied with two 8” round collars. An integral backflow damper is installed in the outlet collar. In a ducted installation, the
dehumidifier pulls air from the living space or HVAC return duct and supplies the dehumidified air to the HVAC supply duct (See Figures 5, 6 & 7).
DUCTED INSTALLATION
• Move supply collar to the desired location, if necessary. (See Supply Collar in SET-UP section.)
• The unit can be ducted to the supply or both the return and supply. The dehumidifier inlet ducting must be a minimum of 6” upstream of the
HVAC system air cleaner and the outlet must be ducted a minimum of 6” downstream of the cooling coil.
An additional option is to duct the dehumidifier inlet and outlet to the return duct. This installation must include wiring the dehumidifier to
activate the HVAC blower during dehumidification. (See Wiring to HVAC System in WIRING section.)
• Use the least amount of ductwork possible. To ensure best performance, do not exceed a total of 50 feet of duct installed in accordance with
SMACNA Standards. UL approved, 8” diameter, insulated duct is recommended for all connections.
• All joints and seams must be sealed.

dehumidifier. See Figure 10.
LEVELING
WIRING
The dehumidifier can be wired to activate the HVAC blower during dehumidification. This is recommended because it offers better circulation
and balancing of the indoor air conditions. Note: Running the HVAC blower during dehumidification does not affect moisture removal efficiency.
If the unit is not wired to the HVAC system, air is pulled through the unit, dehumidified, and circulated solely by the dehumidifier blower.

as desired for comfort or economy. This will vary depending on
location and conditions. Moving the knob toward “MORE DRY”
will increase the amount of time the dehumidifier runs, making
conditions dryer. Moving the knob toward “LESS DRY” reduces the
amount of time the dehumidifier runs, allowing for higher humidity
levels. See Figure 18 for knob setpoint.
START UP/SYSTEM CHECKOUT
1. Check the wiring and restore power to the HVAC equipment
(if applicable).
2. Plug in the dehumidifier and turn on/off switch ON.
3. Check LED indicators located below the wiring access panel. Verify
the green LED is on. The green LED is on when power is applied to
the system.
4. Rotate the dehumidistat knob fully clockwise to ON position.
5. If setup is correct, the dehumidifier blower, and HVAC fan
(if applicable) will turn on. The compressor will turn on after
the dehumidifier blower has run for 3 minutes. Refer to the
TROUBLESHOOTING GUIDE if the dehumidifier blower and/or
compressor do not activate.
6. Check LED indicators. Green should remain on. If Red LED is on,
refer to the TROUBLESHOOTING GUIDE. The red LED turns on
when a fault condition is active. Possible fault conditions include
open float switch or open high temperature switch.
7. After verifying operation, rotate the dehumidistat knob counter-
clockwise to set the dehumidifier to the desired dryness level. Start
at 2-1/2 as the initial setpoint for economy, property protection
and upper end of comfort range. Change dryness level up or down

Technical Support is available Monday through Friday, 8:00 a.m. to 5:00 p.m. CST, at [phone]. Use the troubleshooting guide to help
find and correct system faults. Contact Technical Support before replacing the unit or components or for additional troubleshooting.
SEQUENCE OF OPERATION
The dehumidistat continually measures the humidity of the air in which it is located and controls to the dryness level set on the dial. When
the humidity level rises above the dial setting on the dehumidistat, the dehumidifier blower will turn on and the DEH Amber LED on the power
board (not visible unless dehumidifier cover is removed, see wiring schematic) will illuminate. The HVAC system blower, along with the HVAC
Amber LED (not visible unless dehumidifier cover is removed, see wiring schematic) will also turn on if the dehumidifier is wired to the HVAC
system. After three minutes of blower operation, the dehumidifier compressor will turn on along with the COMPR Amber LED (not visible unless
dehumidifier cover is removed, see wiring schematic). When the humidity level drops below the dial setting on the dehumidistat, both the
compressor and dehumidifier blower will turn off. If wired to the HVAC system, the HVAC blower will also turn off unless the system thermostat
keeps it running. To prevent short-cycling, the compressor will turn on 3 minutes after the blower.
The dehumidifier is equipped with an automatic defrost feature. When the evaporator coil temperature drops below the cut-out point of the frost
sensor, the dehumidifier begins the defrost cycle and the dehumidistat will turn off the compressor and the blower will continue to run. The
compressor will remain off until the evaporator coil temperature rises above the cut-in point of the frost sensor.
