6. Maintenance
WARNING! NOTE: Do not operate the unit without the filter or with a less e
ff
ective filter.
The heat exchange coils inside the unit could become clogged and require disassembly to clean.
Filter non-compliance invalidates the product warranty.
6.1 Standard Air Filter
The Quest Dual Dehumidifier ships with a standard MERV 11 e
ffi
cient pleated fabric filter. This filter should be checked
every six months. Operating the unit with a dirty filter will reduce dehumidifier capacity and e
ffi
ciency and may cause the
compressor to cycle o
ff
and on unnecessarily on the defrost control.
To access the air filter, remove the filter access panel from the end of the Quest Dual Dehumidifier. The filter should be
readily visible and can be removed by pulling it straight out of the Quest Dual Dehumidifier.
We recommend changing the filter at least with every grow cycle.
6.2 Impeller Fan Oiling
The impeller fan motor is factory lubricated for many years of normal operation, and no further oiling is required.
7. Service
WARNING! Servicing the Quest 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.
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.
