Ultra-Aire 70H Installation Instructions
www.Ultra-Aire.com | 1-800-533-7533
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 all sides for maintenance and service. The entire shell needs to be
removed in order to do repairs.
• 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 unwanted
noise may result. Place the Ultra-Aire 70H on supports to raise the base of the unit.
• A drain pan 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 the outside shell. Allow sufficient clearance around the unit.
• Locate the dehumidifier in an area where the cord’s lenght (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 70H, especially
when connecting to the supply
ducting system. The backdraft
damper prevents supply air
from counter flowing through
the Ultra-Aire 70H when it is
not operating. The dehumidifi-
er’s location should be chosen
to allow installation of this
accessory if necessary.
• The Ultra-Aire 70H may be
suspended with the hang kit
or a suitable alternative from
structural members,
ensuring the assembly
supports the dehumidifier’s
base in its entirety. DO NOT
hang the Ultra-Aire 70H from
its’ cabinet.
• Allow for proper drainage and
routing of needed drain pipes.
