Intended Application for 50Hz Quest 706 Dehumidifier
The 50Hz Quest 706 Dehumidifier is designed to operate in temperatures between
56° and 110°F. In order to efficiently control humidity levels, the area in
which the dehumidifier is to be operated must be free of water intrusion or
excessive fresh (outside) air infiltration. Before installing the 50Hz Quest
706 Dehumidifier, water intrusion and air infiltration problems should be
addressed or noted in calculations.

Installation
Location
The 50Hz Quest 706 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 50Hz Quest 706 Dehumidifier as a bench or table.
- DO NOT place the 50Hz Quest 706 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 1 meter clearance around the air intake and exhaust.
Electrical Requirements
- High Voltage Connections
- The 50Hz Quest 706 Dehumidifier must be wired directly to the electrical service. The current draw under normal operating conditions is listed in section 3.
- 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. A ground fault interrupter protected circuit is recommended.
- 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
Condensate Water Removal
Condensate drains by gravity via the drain port. Use 3/4” male NPT PVC pipe.
An optional condensate pump kit may be installed if a lift is required to
dispose of the condensate. Optional parts list for information on the kit.

Hanging Diagram
WARNING:
- Hanging installation must meet all state and local codes.
- Installation should be done by a qualified agency in accordance with these instructions. The qualified service agency installing this high-efficiency refrigeration system is responsible for the installation.
- Check the supporting structure to be used to verify that it has the sufficient load-carrying capacity to support the weight of the unit. Suspend the unit only from the threaded nut retainers. Do NOT suspend from the cabinet.
- Recommended maximum hanger rod is 6 feet (1.8m)
Control Options
The 50Hz Quest 706 Dehumidifier is controlled by an external remote humidistat through a 24V terminal block. External control NOT provided.
Humidity Control
A 24VAC signal is sent by the remote humidistat signals the fan or fan and
compressor to actuate.
Quest Control Options:
- Cloud Control
- DEH 3000R
- Honeywell Humidistat
- Any 24V signal to Dehumidify
24VAC Wiring
The terminal block, low-voltage circuit breaker, and power switch are located
on the intake side of the unit. Turn the power switch to the off position
while wiring the unit.
- FLOAT: {External normally closed dry contact float switch.} No voltage may be applied to the float switch.
- FLOAT: Applying voltage may damage the control and void the warranty. {If no float is used in the system, leave the jumper connected to the terminal block.}
- DEHU: Dehumidification (compressor and fan operation).
- R: 24VAC output
- FAN: Fan operation only.
- C: 24VAC neutral (common)
Note: External devices can be powered between 24V/COM (10VA max). 24V circuit is protected by circuit breaker.
Maintenance
Standard Air Filter
The 50Hz Quest 706 Dehumidifier ships with two standard MERV 13 efficient
pleated fabric filters. This filter should be checked every six months.
Operating the unit with a dirty filter will reduce dehumidifier capacity and
efficiency. To access the air filter, the filter should be readily visible and
can be removed by pulling it straight out of the 50Hz Quest 706 Dehumidifier.
For agriculture, we recommend changing the filter with every grow cycle.
Service
WARNING: Servicing the 50Hz Quest 706 with its high-pressure refrigerant system and high voltage circuitry presents a health hazard that could result in death, serious bodily injury, and/or property damage. Only qualified service personnel should service this unit.
Warranty
A warranty certificate has been enclosed with this unit; read it before any
repair is initiated. If a warranty repair is required, call the factory first
at 1-877-420-1330 for warranty claim
authorization and technical assistance.
Technical Description (Nonstandard patented)
The 50Hz Quest 706 Dehumidifier uses a refrigeration system to remove moisture
from incoming air, and add heat to the air that is discharged. Hot, high-
pressure refrigerant gas is routed from the compressor to the condenser coil.
The refrigerant is cooled and condensed by giving up its heat to the air that
is about to be discharged from the unit. The refrigerant liquid then passes
through a filter/drier and expansion drier which causes the refrigerant
pressure and temperature to drop. It next enters the evaporator coil where the
cool refrigerant absorbs heat from the incoming air and evaporates. The
compressor evacuates the cool refrigerant vapor from the evaporator and
compresses it to a high pressure and temperature to repeat the process.
Ducting Guidelines
CAUTION: 50Hz Quest 706 is intended for use in statics under .5”WG.
- Ducting either the intake or exhaust uses custom Therma-Stor Intake and Exhaust Duct Kits.
- Grills or diffusers on the duct ends must not excessively restrict airflow.
- Effective dehumidification may require ducting to be branched to isolated or stagnant flow areas. Be sure to use appropriate size duct branches to maintain proper feed throughout the ducting system.
- System control should be placed remotely from the dehumidifier in a central location.
- Intake and exhaust ducting should have a minimum of 1 meter from the unit before any turns and maximum of 8m for total run.
Optional duct kits are available from the factory; Exhaust Kit 4039868 and Intake Kit 4038642. See figures below for plenum dimensions and duct diameters. Alternatively, licensed contractors can fabricate duct plenums and reference figures below for safe fastener mounting points.
