7.1 Air Filter
The Quest 150 Dual ships with a standard MERV 8 pleated fabric filter. This should be checked every six months. The
pleated fabric filter can generally be vacuumed clean several times before needing replacement. Operating the unit with a
dirty filter will reduce dehumidifier capacity and efficiency and may cause the compressor to cycle on and off unnecessarily.
Replacement filters can be ordered from your dealer or by calling 1-800-533-7533.
8. Service
WARNING! Servicing the Quest 150 Dual 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.
CAUTION: If the supply cord is damaged, it must be replaced by the manufacturer, its service
agent or similarly qualified person in order to avoid a hazard.
8.1 Technical Description
The Quest 150 Dual 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 capillary tubing which cause the refrigerant pressure
and temperature to drop. It next enters the evaporator coil where it absorbs heat from the incoming air and evaporates.
