5. Installation

5.1 Dehumidifier Setup

5.1 A Location

The Quest 185 Cool 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 185 Cool Dehumidifier as a bench or table. 
•  DO NOT place the Quest 185 Cool 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 185 Cool 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 185 Cool Dehumidifier will help the unit drain with gravity flow. Do not place 

the Quest 185 Cool Dehumidifier directly on structural building members without vibration absorbers or unwanted noise 

may result.
