7.1 Standard Air Filter
The Quest 185 Cool Dehumidifier ships with a standard MERV 11 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, remove the filter access panel from the end of the Quest 185 Cool Dehumidifier. The filter should
be readily visible and can be removed by pulling it straight out of the Quest 185 Cool Dehumidifier.
We recommend changing the filter at least with every grow cycle.
7.2 Impeller Fan Oiling
The impeller fan motor is factory lubricated for many years of normal operation, and no further oiling is required.
8. Service
8.1 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.
8.2 Refrigerant Charging
WARNING!
Servicing the Quest 185 Cool 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.
Service must be performed by a qualified service technician.
If the refrigerant charge is lost due to service or a leak, the leak should be repaired and a new charge must be ac-
curately weighed in. If any of the old charge is left in the system, it must be recovered before weighing in the new
charge. Refer to the unit nameplate for the correct charge weight and refrigerant type.
