7. Maintenance
7.1 Standard Air Filter
The Quest 215 Dual is equipped with a pleated cloth air 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 215 Dual. The filter should be readily
visible and can be removed by pulling them straight out of the Quest 215 Dual.
The pleated cloth filter can generally be vacuumed clean several times before needing replacement. Replacement filters
can be ordered from the factory or purchased locally if available. DO NOT operate the unit without the standard filter
or with a less effective filter than the standard filter. The heat exchange coils inside the unit could become clogged and
require disassembly to clean. Filter non-compliance invalidates the product warranty.
7.2 High Efficiency Air Filter - MERV 14
An optional high efficiency pleated microglass paper filter is available for the Quest 215 Dual . This filter is rated as 90%-
95% efficient by the ASHRAE Dust Spot test method 52-76. The high efficiency pleated microglass paper filter should
be used in conjunction with the standard filter, and placed directly beneath the standard filter.
This filter is able to remove allergy causing particles from the airstream. The high efficiency filter has a much larger
surface area than the standard filter, thus the standard filter may need to be cleaned or replaced several times before the
high efficiency filter requires replacement. Be careful not to damage the fabric media when handling the high efficiency
pleated paper filter. Do not attempt to clean the high efficiency pleated paper filter. It should be replaced when it
becomes restrictive (See Figure 7).
7.3 Impeller Fan Oiling
The impeller fan motor is factory lubricated for many years of normal operation, and no further oiling is required.
7.4 Optional Fresh Air Return
Check and clean the screen on the outdoor fresh air return seasonally. The screen may become plugged during the
seasons when there are many particles in the outdoor air.
