Recommended Closet Installation - Ultra-Aire 70H Installation Instructions Manual

Recommended Closet Installation

Due to space limitations, a closet installation may require additional considerations. Locate the dehumidifier
under or next to the HVAC system as space allows. A passive vent or louver door is required to allow air to
be pulled in from the living space.
• No inlet duct is required. Air is pulled through the louvers or grille from the living space.
• Install a 6" insulated duct from outside, teeing into the 8" return duct of the Ultra-Aire 70H to provide
fresh air ventilation (optional).
• Control should be placed in a central location or the on board control can be used for this installation.
• Where inlet space is restricted, the inlet duct collar is optional.
• Where outlet space is restricted, the outlet duct collar is optional or vertical flow through may be preferred.
WARNING!
WHEN INSTALLING THE DEHUMIDIFIER AS PART OF A COMBUSTION TYPE HVAC SYSTEM (GAS,
OIL, PROPANE, ETC.), FOLLOW ALL LOCAL AND NATIONAL BUILDING AND SAFETY CODES.
