Install Dehumidifier—Attic Installation
NOTES: 
Install a secondary drain pan with a drain or float interrupt 
under the dehumidifier to prevent damage to ceiling or living 
space below.
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. 
1. Disconnect power.
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 anti-siphon vent for it to drain 
properly.
5. If needed, install a condensate pump kit (optional).
6. Place a secondary drain pan under the dehumidifier.
7. Using a 10" duct, attach the discharge air supply on the 
dehumidifier to the return air supply on the existing lower 
level 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.
8. Attach the return air supply on the dehumidifier to the return 
air supply on the existing upper level 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.
9. If desired, install a fresh air duct. See “Install Dehumidifier—
Existing Furnace or Air Handler with Fresh Air Duct.”
10. If desired, install a supply air duct to the basement or crawl 
space. See “Install Dehumidifier—Existing Furnace or Air 
Handler with Dry Air to the Basement or Crawl Space.”
