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!
REMOVE COMPRESSOR SHIPPING TIE FROM THE UNIT. FAILURE TO REMOVE SHIPPING TIE
WILL CAUSE EXCESS VIBRATION TO BE TRANSMITTED TO THE FRAME.
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.
• 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 unwanted
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. The Ultra Aire XT205H requires a dedicated 20 Amp circuit.
• 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.
