4. INSTALLATION
4.1 LOCATION
The Quest 506 Dehumidifier can be installed in a variety of locations to meet the owner’s needs as
listed below. In all cases keep the following cautions in mind:
• It is designed to be installed INDOORS IN A SPACE THAT IS PROTECTED FROM RAIN AND
FLOODING.
• Install the unit with space to access side panel for maintenance and service. DO NOT INSTALL
UNIT WITH ACCESS PANEL INACCESSIBLE.
• Avoid discharging the air directly at people, or over the water in pool areas.
• Be certain there is NO chance the unit could fall into water or be splashed and that it is plugged
into a GROUND FAULT INTERRUPTER.
• DO NOT use the Quest 506 Dehumidifier as a bench or table.
• DO NOT place the Quest 506 Dehumidifier directly on structural members. Provide vibration
isolation in order to minimize operational vibration and/or noise.
• A drain pan MUST be placed under the unit if installed above an area where water leakage could
cause damage.
• DO NOT obstruct the supply or return air. Maintain a minimum 3’ clearance around supply and
return air.
4.2 ELECTRICAL REQUIREMENTS
WARNING!
Electrical shock hazard: Electrical power must be present for
some test. These test should be performed by a qualified service person.
The Quest 506 dehumidifier plugs into NEMA 6-20R rated receptacle. The Quest 506 277v
dehumidifer plugs into a NEMA L7-20P rated receptacle. The amp draws are listed on page 4 of
this manual. Connecting to electrical power must comply with all national, state and local electrical
codes. A ground fault interrupter protected circuit is recommended. This unit shall not be used with
an extension cord.
WARNING!
The On/Off switch above the 24VAC control reset only turns off
the 24VAC circuit. It does not disconnect the main power.
Low Voltage Connections
Install the external control in a central area of the structure where it will sense the relative humidity
accurately. Do not install the control sensor where it may not accurately measure the relative
humidity such as near HVAC supply registers, near exterior doors or near pool or spas. The installer
must supply the wiring between the dehumidifier and the external control. Be sure to safely route
the control wiring to prevent damage during installation. Be careful not to cross the wires when
connecting the dehumidifier and the external control.
The controls of the dehumidifier are powered by a low voltage circuit (24VAC) and must NEVER contact
or be connected to a high voltage circuit. The control terminals are labeled to prevent confusion.
WARNING!
Damaged power cords can only be replaced with one by the unit
manufacturer.
