MAINTENANCE

WARNING! Do not operate the unit without the filter or with a less effective filter. The heat exchange coils inside the unit could become clogged and require disassembly to clean. Filter non-compliance invalidates the product warranty.

STANDARD AIR FILTER

The Quest 506 Dehumidifier ships with a standard MERV 13 efficient pleated fabric filter. This filter should be checked every six months. Operating the unit with a dirty filter will reduce dehumidifier capacity and efficiency and may cause the compressor to cycle off and on unnecessarily on the defrost control.
To access the air filter, the filter should be readily visible and can be removed by pulling it straight out of the Quest 506 Dehumidifier.
We recommend changing the filter at least with every grow cycle.

SERVICE

WARNING! Servicing the Quest 506 with its high-pressure refrigerant system and high voltage circuitry presents a health hazard which could result in death, serious bodily injury, and/or property damage. Only qualified service people 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 (NON-STANDARD PATENTED)

The Quest 506 Dehumidifier uses a refrigeration system similar to an air conditioner’s to remove heat and 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.

TROUBLESHOOTING

Test to determine if the problem is with the unit or control:

1. Detach field control wiring connections from unit.
2. Connect the 24V and FAN together; only the impeller fan should run. Disconnect the wires.
3. Connect the 24V and DEHU together; fan should run, Compressor should come on after a short delay.
4. Run the unit for 1 hour in an environment that is greater than a 50 F dew point. The unit should produce water from the drain port.
5. If these tests pass, the unit is working properly. You should check the control and field wiring for problems if the unit is not activating. Check for air restrictions, low temperature, low humidity, and refrigerant charge if the unit is not producing water.

DUCTING GUIDELINES

CAUTION! Quest 506 is intended for use in statics under .25”WG.

• Ducting either the intake or exhaust use a minimum of two 12” diameter round ducts minimum.

• 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 4 feet from the unit before any turns.
  CAUTION! Do not connect with a static pressure greater than +.25”wg. Contact technical support for additional details.

• Optional duct kits are available from the factory: Exhaust Kit 4038641 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.
