Check local codes and HVAC supplier. Check existing electrical supply, and read “Electrical Requirements” and “Location Requirements” before purchasing parts.

LocationRequirements

■The dehumidifier may be installed on all new or existing furnaces or air handlers used in residential applications.

■The whole house dehumidifier is designed to be located indoors.

■Locate the whole house dehumidifier as close to the return air duct of an existing furnace or air handler as possible to minimize the required ductwork for connecting the dehumidifier to the existing furnace or air handler.

■The location should allow for access to the filter access panel at the front of the dehumidifier for inspection and replacing the filter. See the Minimum Clearance Requirements chart.

■The location must allow for access to the electrical access panel for servicing and maintenance.

■Locate the whole house dehumidifier in an area where the temperature is between 40ºF (4ºC) and 125ºF (52ºC). If the dehumidifier is located in an area of extreme heat or high humidity, additional external insulation may be required to prevent condensation on the exterior of the dehumidifier.

■If the dehumidifier is located above a living area or above an area where water leakage may cause damage (see local codes for other requirements), a secondary drain pan must be installed under the dehumidifier.

■The controls for the whole house dehumidifier are remote from the dehumidifier and must be located in the space that is to be conditioned. The controls are low voltage (24-volt) and should be connected to the dehumidifier with code approved, low voltage thermostat cable.

■If the dehumidifier is located directly on structural building members, use vibration absorbers/eliminators.
