Ultra-Aire 98H Installation Instructions
www.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 unwanted
noise may result. Place the Ultra-Aire 98H 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 98H, especially
when connecting to the supply ducting
system. The backdraft damper prevents
supply air from counter flowing through
the Ultra-Aire 98H when it is not
operating. The dehumidifier’s location
should be chosen to allow installation
of this accessory if necessary.
• The Ultra-Aire 98H 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 98H from its cabinet.
• Allow for proper routing and drainage
of needed drain pipes.
