Safety and Installation Instructions
For use with Model 1700 Whole-Home Dehumidifier
WARNINGS
115 volts may cause serious injury from electrical shock.
Disconnect electrical power to the furnace, air conditioner and

BACKGROUND
The Service Part Number 4522 Basement Kit is used to
facilitate installation of the Model 1700 Dehumidifier in the
“Whole House/Localized Convertible Installation” application.
With the Model 1700 installed in this configuration, the
dehumidifier will automatically switch between whole-house
dehumidification when the HVAC equipment is on, and
localized dehumidification when the HVAC equipment is off.
Typically, this installation configuration is used to dehumidify a
whole house and a separate conditioned living space like a
finished basement.
PARTS PROVIDED
(2) Normally Closed 8” Damper, Model 6508.
(2) Normally Open 8” Damper, Model 6608.
(1) 40VA, 24 VAC plug in transformer, Model 8027.
INSTALLATION PROCEDURE
Installer should refer to the Model 1700 Safety and
Installation Instructions prior to installing the Basement Kit.
1. Install the normally closed dampers (6508) in the duct runs
leading to the air handler supply and return plenums.
2. Install the normally open dampers (6608) in the duct runs
leading back to the unconditioned space.
3. Wire power to the damper actuators using the 40VA,
24 VAC transformer (8027). The transformer is wired in
series with the damper actuators and the wires are
terminated to the Model 1700 control board at terminals
labeled DEH DAMPER. Plug transformer into 115 VAC
grounded wall receptacle.
4. Complete installation, set-up and checkout of the Model
1700 Dehumidifier as documented in the Model 1700 Safety
and Installation Instructions.
SEQUENCE OF OPERATION
When the HVAC blower and the model 1700 Dehumidifier are
on, the dampers will energize and the dehumidifier will
operate in the whole-house mode. When the HVAC blower is
off, the dampers will be de-energized and the dehumidifier
will operate in the localized mode.
Note – The dampers will also be de-energized when the
dehumidifier is off. This will prevent backflow of air when only
the HVAC blower is on.
