Allow adequate clearance to walls for normal unit service. INSTALLING THE EQUIPMENT CAUTION! Do not install the unit outdoors or in a UNIT LOCATION location where it will be subjected to Unit location is very important as it will determine precipitation of any kind. the overall length of the connection ducts. Locate the unit as close as possible to the indoor portion MOUNTING of the resident’s air conditioning unit or air The unit may be mounted on a flat surface or handling unit, in the attic, basement, garage, or suspended. If mounted on a flat surface use the equipment room. The dehumidifier may be placed four rubber mounting feet provided. To minimize above, below or level with the air handing unit; unwanted vibration select a level mounting however, removal of condensate must be surface. Adjust the four mounting feet to considered when determining the location. compensate for any irregularities in the surface. If the unit is mounted above a ceiling or in an Ensure that the unit is sitting on all four feet.

Ducts should be as short as possible, not to exceed 100 ft. equivalent length and supported in compliance with the manufacturer’s recommendation. CAUTION! All duct connections must be sealed. Any leakage in the duct work will adversely affect the operation of the dehumidifier and may lead to unsatisfactory performance. DAMPERS Optional dampers may be installed in the outlet duct, inlet duct, or in an outside air duct. These dampers must be full flow motorized type. Do not use any type of pressure operated damper as unacceptable pressure drop will affect unit operation. All dampers must be installed in compliance with the manufacturer’s recommendations and be insulated, and sealed per the section on ducts, above.
