Switch Assembly, Micro; Thermostat And Solenoid Valve(Hot Gas Defrost); Humidistat; Dryer Assembly - LG DHA1260HL Service Manual

1.6.3 SWITCH ASSEMBLY, MICRO

The micro switch assembly, which is located on the back of the unit, automatically shuts off the dehumidifier when the bucket is
full (note, the Auto Shut Off lights, to indicate bucket must be emptied). Once the bucket has been emptied and replaced, the
unit once again turns itself on.
1.6.4 THERMOSTAT AND SOLENOID VALVE (Hot gas defrost)
The THERMOSTAT senses frost build-up on the evaporator coil and automatically shuts off the fan. The compressor continues
to run, hot gas(solenoid valve is open) is supplied through the coil and melting the frost. When the coil is defrosted, the fan
automatically restarts, and hot gas valve is closed, and dehumidifying resumes.

1.6.5 HUMIDISTAT

Humidistat maintains the constant relative humidity in the
room automatically to satisfy particular need.
(When the relative humidity in the room increases to the
selected level, the dehumidifier starts automatically.) Once
the relative humidity drops to the selected level, the
dehumidifier stops automatically.
When first using the dehumidifier, it is recommended, for
the first three or four days, to operate the unit with the
humidistat control set at the 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 DRYER ASSEMBLY

Dryer is used to prevent water from overflowing in all tubes
and H/E assembly-condenser assembly and evaporator
assembly-and an acid, water and bad material from heating
oil. 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.
