Approximate Humidity Levels Per Setting:
“Drier”
20% to 30% Relative Humidity
“Normal”
45% to 55% Relative Humidity
(Recommended)
“Humid”
80% to 90% Relative Humidity
The dehumidifier will run until the relative humidity (RH) is reduced to the humidity control dial setting.
Quality humidity meters are available from the factory and are recommended to accurately monitor humidity
levels. Refer to the options and accessories table in this document.
6.2 Fan Switch
Turning the impeller switch to “FAN ON” will cause the unit’s internal impeller to run continuously, whether the
unit is dehumidifying or not. This function is desirable if the unit is used for air circulation.
Turning the fan switch to “FAN AUTO” will cause the unit’s internal blower to run only while the unit is
dehumidifying.
7. Maintenance
CAUTION! NOTE: Do not operate the unit without the filter or with a less effective
filter. The heat exchange coils inside the unit could become clogged and require
disassembly to clean.
7.1 Air Filter
The Quest 110 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.
