DEHUMIDIFIER ELECTRICAL REQUIREMENTS

The dehumidifier plugs into a common grounded 115 VAC outlet. The device draws 1.4 Amps at 80°F and 60% RH and can 

be plugged into a shared branch circuit. Locate the dehumidifier in an area where the cord’s length (10') easily reaches a 

115 VAC electrical outlet. If used in an area that may become wet, a GFCI protected circuit is recommended. Consult local 

electrical codes for further information. Field wiring must comply with the National Electric Code (C.E.C. in Canada) and 

any applicable local codes or ordinances.
Quest offers a variety of control devices for use with the Quest 185 Cool. The control is to be located  

remotely from the dehumidifier and placed in the space to be conditioned. A low voltage (24 Volt) control MUST be used with the 

Quest 185 Cool and MUST be connected with low voltage (18-22 gauge) thermostat wire.

CAUTION!

DO NOT ALLOW THE YELLOW LEAD TO CONTACT THE RED OR WHITE LEAD ON THE  

DEHUMIDIFIER OR DAMAGE TO THE TRANSFORMER WILL RESULT. 

Electrical Precautions

•  Do not install the control where it may not accurately sense 

the relative humidity such as near HVAC supply registers, near 

exterior doors, on an outside wall, near a window, or near a water 

source. 

•  The control wires leaving the Quest 185 Cool and the control 

are numbered and color-coded to  

prevent confusion. 

•  Be sure to consult the electrical schematic in the 

CONTROLS Section (page 26) of this manual or inside 

the access panel of the dehumidifier before making control 

connections.

 

WARNING!

THE REMOTE CONTROLS OF THE QUEST 185 COOL ARE POWERED BY A LOW VOLTAGE CIRCUIT 

(24 VAC) AND MUST NEVER CONTACT OR BE CONNECTED TO A HIGH VOLTAGE CIRCUIT.

 

CAUTION!

SOME OF THE CONTROL WIRES LEAVING THE 

QUEST 185 COOL MAY NOT BE USED WITH  

CERTAIN CONTROLS AND SHOULD BE LEFT 

UNCONNECTED WITH WIRE NUTS TAPED 

ONTO THE STRIPPED ENDS FOR SAFETY.
