4. Installation
4.1 Location
The Quest Dual 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 the back and side panels for maintenance and service and also to allow easy
access to the filter cover panel. DO NOT INSTALL UNIT WITH THE FRONT PANEL OR FILTER COVER
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 Dual Dehumidifier as a bench or table.
• DO NOT place the Quest Dual 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.
Place the Quest Dual Dehumidifier on supports that raise the base of the unit 2.5” above the top of the flanges on the
drain pan beneath it. Raising the Quest Dual Dehumidifier will help the unit drain with gravity flow. Do not place the
Quest Dual Dehumidifier directly on structural building members without vibration absorbers or unwanted noise may
result.
The Quest Dual Dehumidifier may be suspended with steel hanger straps or a suitable alternative from structural
members, unit must be supported from underneath. Don’t hang from sides or ends. Remember to place a drain pan
under the unit if it is suspended above a finished area or above an area where water leakage could cause damage.
See
section 4.4
4.2 Electrical Requirements
The Quest Dual Dehumidifier plugs into NEMA rated Receptacles. The amp draws for each unit under normal operating
conditions are listed on page 4. A ground fault interrupter protected circuit is required.
Install the remote control panel in a central area of the structure where it will sense the relative humidity of the structure
accurately. Do not install the control panel where it may not accurately sense the relative humidity such as near HVAC
supply registers, near exterior doors, or near a pool or spa.
The installer must supply the wiring between the Quest Dual
Dehumidifier and the control panel. Be sure to safely route the control wiring to prevent damage during installation. Be
careful not to cross the wires when connecting the Quest Dual Dehumidifier and the remote control panel.
The remote controls of the Quest Dual Dehumidifier are powered by a low voltage circuit (24 VAC) and must NEVER
contact or be connected to a high voltage circuit. The control terminals and remote control are labeled and numbered to
prevent confusion. Be sure to consult the electrical schematic in this manual or inside the access panel of the Quest Dual
Dehumidifier before making the control connections.
