Envirowise XT155H Installation Instructions
GENERAL SET UP
Removal of Compressor Shipping Support
The Envirowise XT155H 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 Envirowise XT155H 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
Envirowise XT155H, especially when
connecting to the supply ducting system.
The backdraft damper prevents supply air
from counter flowing through the Envirowise
XT155H when it is not operating. The
dehumidifier’s location should be chosen
to allow installation of this accessory if
necessary.
• The Envirowise XT155H 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 Envirowise
XT155H from its cabinet.
• Allow for proper routing and drainage of
needed drain pipes.
