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 Dry
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 Dry and the remote control panel or damage to the transformer may result.
The remote controls of the Quest Dry are powered by a low voltage circuit (24 VAC) and must NEVER contact or be
connected to a high voltage circuit. The control wires leaving the Quest Dry and the remote control panels are numbered
and color-coded to prevent confusion. Some of the control wires leaving the Quest Dry may not be used with certain
control panels and should be left safely disconnected with wire nuts taped onto the stripped ends. Be sure to consult the
electrical schematic in this manual or inside the access panel of the Quest Dry before making the control connections.
4.3 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.
4.4 Ducting
4.4A Installing Duct Collars
The Quest Dry is equipped with 10" and 6" round inlet collars and a 10" round (ovaled) exhaust collar. Follow instructions
included with collars.
4.4B Ducting for Dehumidification
For the ideal installation, draw air from the central part of the area to be dried and return it to the isolated areas. The
ductwork of the existing heating system can be used to supply air to the area. If the existing supply goes to isolated areas
of the structure, discharge the supply of the Quest Dry into the supply of the existing heating system. If the existing
heating system incorporates a central supply, installation of a separate supply duct from the Quest Dry to each isolated
area is recommended. All flexible ducting connected to the Quest Dry should be UL listed.
The inlet of the Quest Dry is the 10” diameter hole in the filter enclosure of the unit. A 10” round collar is supplied with
the unit to attach to round duct. The duct may be permanently attached to the collar. A 6” round collar is provided with
