6. Maintenance
Do not operate the unit without the filter or with a less effective filter.
Filter non-compliance invalidates the product warranty.
6.1 Standard Air Filter
The Quest 876 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 Quest 876
Dehumidifier.
For agriculture, we recommend changing the filter with every grow cycle.
7. Service
Servicing the Quest 876 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 personnel 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
(Non standard patented)
The Quest 876 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.
