4. Installation
4.1 Location
The Quest 876 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.
• DO NOT use the Quest 876 Dehumidifier as a bench or table.
• DO NOT place the Quest 876 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 air intake and exhaust. Maintain a 4ft clearance around the air intake and exhaust.
4.2 Electrical Requirements
Electrical shock Hazard: Electrical power must be present for some
tests. These tests should performed by a qualified service person.
High Voltage Connections
The Quest 876 Dehumidifier must be wired directly to the electrical service. The current draw under normal operating
conditions is listed in section 3. A ground fault interrupter protected circuit is required.
Information required for proper electrical service installation and overcurrent protection may be found on the
Dehumidifier nameplate. The unit power switch is a disconnect switch. Route power and ground wires through the
electrical knockout hole. Electrical input power wiring must comply with all national, state, and local electrical codes.
Make electrical connections according to the wiring diagram provided in this manual and inside the access panel of the
Dehumidifier.
Low Voltage Connections
Install the external control in a central area of the structure where it will sense the relative humidity accurately. Avoid
installing the sensor near HVAC supply registers, near exterior doors, or near pool or spa. The installer must supply the
wiring between the Dehumidifier and the control panel. Be sure to safely route the control wiring to prevent damage
during installaion. Be careful not to cross the wires when connecting the Dehumidifier and the 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.
For more information on controls, see section 5.
