Advantages of fresh air ventilation:
■Outside air is filtered before entering the building.
■Outside air will be dehumidified by the dehumidifier before entering the building.
■Outside air entering the building through the dehumidifier helps equalize pressure to prevent humid air from entering the building through other means.
■In cold climates, outside air can have a lower dew point and can lower humidity inside the building without running the dehumidifier.
WARNING
Electrical Shock Hazard
Disconnect power before servicing.
Replace all parts and panels before operating.
Failure to do so can result in death or electrical shock.
NOTE: When using the existing duct system, the dehumidifier fan and the existing system fan must be interlocked by using the low voltage interlock method provided with the dehumidifier. See the wiring diagrams in the “Electrical Connections” section.
WARNING
Excessive Weight Hazard
Use two or more people to move and install dehumidifier.
Failure to do so can result in back or other injury.
2.Place the dehumidifier in final location. See “Location Requirements.”
3.Attach ³⁄₄" PVC pipe to the condensate drain outlet. See “Location Requirements.”
4.Run the PVC pipe to an outdoor drain. Any horizontal run of drain pipe must have an
5.If needed, install a condensate pump kit (optional).
6.Using a 10" duct, attach the discharge air supply on the dehumidifier to the return air supply on the existing furnace or air handler.
NOTE: Install ductwork in accordance with NFPA 90B Standard for the Installation of Warm Air Heating and Air Conditioning Systems (latest edition) and any local codes.
7.Attach the return air supply on the dehumidifier to the return air supply on the existing furnace or air handler near the return air grille.
NOTE: Do not draw air directly from the kitchen, bathroom, laundry room or unconditioned isolated basement.
8.Using a 6" diameter insulated duct, attach to the return plenum on the dehumidifier.
9.Install the outside air intake in a location away from undesirable fumes, gases and odors.
10.Install a screened intake hood on the outside air intake duct. Be sure screen is clear of debris at all times to ensure proper air flow to dehumidifier.
11.Install a manual damper on the return air side of the dehumidifier.
NOTE: If desired, a power damper may be installed.
