Envirowise SD12 Installation Instructions
GENERAL SET UP
Important Precautions
• The dehumidier is designed to be installed indoors in a space that is protected from rain and ooding.
• Install the dehumidier with enough space to access the back and 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 dehumidier 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 dehumidier as a bench or table.
• DO NOT place the dehumidier directly on structural building members without vibration absorbers or unwanted
noise may result. Place the dehumidier on supports to raise the base of the unit.
• A drain pan with a oat switch MUST be placed under the dehumidier if installed above a living area or above
an area where water leakage could cause damage.
Location Considerations
• Avoid using the dehumidier in stand-alone crawl space or basement applications. The cool air in the crawl
space or basement, along with the cool air produced by the dehumidier, will have a negative eect on the
performance of the machine and cause the system to fall into a defrost cycle.
• Allow sucient clearance to handle the unit’s overall dimensions as well as the necessary return and supply
ductwork to the unit.
• Allow sucient clearance for lter removal and to prevent airow obstruction.
• Electrical service access will require the removal of a side panel. Allow sucient clearance on a side of the unit.
• Locate the dehumidier in an area where the cord’s length (9') easily reaches a 115 VAC electrical outlet with a
minimum of a 15 Amp dedicated
circuit capacity.
• Locate the dehumidier in an area
where eld 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 dehumidier, especially
when connecting to the supply
ducting system. The backdraft
damper prevents supply air from
counter owing through the
dehumidier when it is not
operating. The dehumidier’s
location should be chosen to
allow installation of this accessory
if necessary.
• The dehumidier may be suspended
from structural members with steel
hanger straps or a suitable
alternative, ensuring the assembly
supports the dehumidier’s base
in its entirety. DO NOT hang the
dehumidier from its cabinet.
• Allow for proper routing and drainage
of needed drain pipes.
