The Quest 185 Cool 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.
5.1 B Electrical Requirements
The Quest 185 Cool 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 185
Cool 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 185 Cool Dehumidifier and the remote control panel.
The remote controls of the Quest 185 Cool 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 185 Cool Dehumidifier before making the control connections.
CAUTION! For proper drainage, the unit must be mounted so the drain outlet is at least 4”
above the floor drain, and must be fully supported under the base.
5.1 C Condensate Water Removal
Condensate drains by gravity via the drain port. Use 3/4” male NPT PVC pipe. Route drain pipe to drain. Install a trap if
possible. Take care when installing drain pipe to drain port. Use an adjustable wrench to secure the drain port. An optional
condensate pump kit may be installed if a lift is required to dispose of the condensate. The condensate pump kit can be
ordered directly from the factory. See the optional parts list for information on the kit.
When installing the drain hose make sure the feet are extended such that the dehumidifier is 2 1/2” off the ground.
Then coil the drain hose under itself or position a spacer to lift the hose 1” off the ground after the hose has touched the
ground. This procedure will create a trap that ensures your unit drains correctly. See the diagram below for further visual
clarification.
