Ultra-Aire.com | (800) 533-7533
Important Precautions
• The device is designed to be installed indoors in a space that is protected from rain and flooding.
• Install the unit with enough space to access one of the side panels for maintenance and service.
• Avoid directing the discharge air at people. The dehumidifier should be used in the upright position.
• If used near a water source, be certain there is no chance the unit could fall into the water or get splashed and
that it is plugged into a dedicated circuit and Ground Fault Circuit Interrupter (GFCI) protected outlet.
• DO NOT use the dehumidifier as a bench or table.
• DO NOT place the dehumidifier directly on structural building members without vibration absorbers or unwant-
ed noise may result. Place the Ultra Aire Dehumidifier on supports to raise the base of the unit.
• A drain pan with a float switch MUST be placed under the dehumidifier if installed above a living area or above
an area where water leakage could cause damage.
Location Considerations
• Allow sufficient clearance to handle the unit’s overall
dimensions as well as the necessary return and
supply ductwork to the unit.
• Allow sufficient clearance for filter removal and to
prevent airflow obstruction.
• Electrical service access will require the removal of
a side panel. Allow sufficient clearance on a side of
the unit.
• Locate the dehumidifier in an area where the cord’s
length (9') easily reaches a 115 VAC electrical outlet
with a minimum of a 15 Amp circuit capacity.
• Locate the dehumidifier in an area where field wiring
the control (low voltage) to the unit will be possible.
• It is recommended that a backdraft damper be
used in the discharge duct of the Ultra Aire
Dehumidifier, especially when connecting to the supply ducting system. The backdraft damper prevents supply
air from counter flowing through the Ultra Aire Dehumidifier when it is not operating. The dehumidifier’s
location should be chosen to allow installation of this accessory if necessary.
• The Ultra Aire Dehumidifier may be suspended from structural members with steel hanger straps or a suitable
alternative, ensuring the assembly supports the dehumidifier’s base in its entirety. DO NOT hang the Ultra Aire
Dehumidifier from its cabinet.
• Allow for proper routing and drainage of needed drain pipes.

Removal of Compressor Shipping Support
The Ultra Aire Dehumidifier uses a compressor to power the
refrigeration system. To protect the compressor and refrigeration
system during shipping, a plastic tie wrap secures it to the unit’s
frame. Remove the tie wrap by cutting the tie wrap and pulling
from the unit as shown. After removing tie wrap, insert plastic plugs
provided into the holes.
CAUTION!
CAUTION!
REMOVE COMPRESSOR SHIPPING TIE FROM THE UNIT. FAILURE TO REMOVE SHIPPING TIE
WILL CAUSE EXCESS VIBRATION TO BE TRANSMITTED TO THE FRAME.
