INSTALL DUCTWORK
DUCTING THE 8190FF
1.
Install insulated ductwork from the 6" ventilation opening to the
fresh air inlet hood.
2.
Tape or mastic the duct to the hood and collar, and seal the duct
insulation on the ends using zip ties or tape.
3.
Install ductwork from the 10" 8190FF collar to a location with air
representative of the whole house. If the 10" duct is located in an
unconditioned space such as an attic or garage, use insulated duct
and tape/seal the duct and insulation as you would the fresh air
intake duct. Suggested dehumidifier inlet ducting:
• Install a separate register with 10" collar in the space to be
dehumidified.
• Connect the 10" duct to a return air plenum or to the return
air duct.
Refer to dehumidifier
Installation Instructions
and
Owner’s Manual
for instructions for ducting the dehumidifier to your HVAC system.
WIRING THE 8190FF
Remove/turn off the fuse or circuit breaker that provides/will provide
power to the dehumidifier before starting wiring. Do not restore
power until all wiring is complete.
1.
Wiring to the Model E100V dehumidifier (see
FIGURE 3
).
• Use the included switched-power jumper wire and 2-wire
connector to attach one of the 8190FF wires to one of the VENT
terminals on the dehumidifier user interface.
• Use the power harness included with the E100V dehumidifier
to connect the dehumidifier power port to the unused VENT
terminal and 8190FF wire.
2.
Wire to a Model E100 or Model 1850 dehumidifier (see
FIGURE 4
).
• Use 18-22 AWG wire to attach one of the 8190FF wires to one of
the VENT terminals on the dehumidifier user interface.
• Install the 24VAC transformer, preferably to the junction box used
for the dehumidifier power outlet. Make sure the fuse or circuit
breaker that serves the junction box to which the transformer is
to be wired, has been removed/turned off
• Use 2-wire cable, 22 AWG minimum, to connect the transformer
to the unused VENT terminal and 8190FF wire.
