1.6.5 HUMIDISTAT
Humidistat controls constant relative humidity in the room
automatically.
When the relative humidity in the room increases to the
selected level, the dehumidifier starts automatically. And the
relative humidity drops to the selected level, the
dehumidifier stops automatically.
When the first using the dehumidifier, it is recommended,
for the first three or four days, to operate the unit with the
humidistat control set to MAX. At this setting, the unit will
run continuously.
When the sweating has stopped and the dampness odors
have gone, it is preferable to select the humidistat position
that will best suit local conditions.
The relative humidity range it can control is from 20 % to
80%. (See Figure 3)
NOTE: The relative humidity at the number is the
approximate value.
1.6.6 DRIER (For some models)
Dryer is used to prevent capillary blockage from moisture in
the refrigerant system and H/E, condenser and evaporator.
Also, dryer is used to remove corrosion of the components.
NOTE: When dryer is replaced, proper injection to
capillary is needed. On opening the dryer, it
should be welded instantly. The oxidization of
dryer inside and all tubes inside after welding
can be prevented.

1.6.3 MICRO SWITCH
The micro switch assembly, which is located on the barrier of inside unit, automatically shuts off the dehumidifier when the
bucket is full (note, the Auto Shut Off lights, to indicate bucket must be emptied). The bucket replaces in its place, the unit again
turns itself on.
1.6.4 AUTO DEFROST
When frost builds up on the cooling coils, the compressor will cycle off until the frost disappears. The fan continues to run.
NOTE: This unit is designed to be operated at temperatures above 65°F(18°C). If the dehumidifier is operated in low
temperature conditions, the temperature and humidity conditions of room are low, some frost can be formed in
its evaporator coil and the unit will be operated ON/OFF repeatedly. In this case, please check on your room
temperature condition and stop the unit.
