6.1 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.
7. Service
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.
7.1 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.
7.2 Technical Description
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.
8. Ducting Guidelines
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.
Do not connect with a static pressure greater than +.25”wg. Contact
technical support for additional details.
