Quest Dry RDS 10
Installation, Operation and Maintenance Instructions
3.8 Hour Meter
The digital hour meter displays the amount of time the dehumidifier has been turned on to the tenth of an
hour. The hour meter continuously cycles between total machine hours and job hours every 3 seconds.
Hours are stored in memory even when the unit is unplugged. The previous totals will be displayed next
time the unit is powered on.
3.9 HOURS Button
Pressing the HOURS button displays the hour meter when the unit is turned off but plugged into power. To
reset job hours, press and hold the HOURS button for 5 seconds when the unit is operating.
3.10 DEFROST Light
The DEFROST light turns on when the unit is in defrost cycle and indicates when the compressor is off.
4. Maintenance
4.1 Air Filter
The Quest Dry RDS 10 is equipped with a pleated media air filter that must be checked regularly. The
standard filter is a MERV-8 high efficiency filter. Operating the unit with a dirty filter will reduce the
dehumidifier’s capacity and efficiency and may cause the compressor to cycle off and on unnecessarily. The
filter can generally be vacuumed clean several times before needing replacement. Replacement filters can be
ordered from the manufacturer or purchased locally if available.
IMPORTANT: DO NOT operate the unit without the filter or with a less effective filter as the heat
exchanger and coils inside the unit could become clogged and require disassembly to clean.
4.2 Storage
There are two issues to consider when the Quest Dry RDS 10 is stored between uses and both pertain to the
water trapped in the unit: damage caused by freezing or biological growth. The effect of the trapped water
can be greatly reduced if precautions are taken to remove as much as possible before storage.
1. Use the pump PURGE button to reduce the water level in the reservoir
2. Walk out the hose to drain it completely
In order to reduce biological growth flush the unit with a biofungicide that is approved for use with
copper, aluminum, polyethylene and ABS. To flush:
1. Run the hose to a drain
2. Plug in the unit but do not turn it on
3. Remove the air filter. Slowly pour a pint of the chemical through the top so that it drains into the heat
exchanger
4. Use PURGE button to remove chemicals in reservoir. Run PURGE until hose runs dry
5. Walk out hose to drain completely
6. Replace air filter
