INSTALLATION METHODS
1. Caster installation method: Take the machine body, caster axis,
caster and screws of the packaging case, and incline the machine
body. As shown in picture 2, fix the caster axis on the machine body
with 4 screws in counter-position, and fix the caster at both sides
of the axis also in counter-position. Upon end of the fixing, put the
body upright.
2. Upper steel pipe installation method: screw down the two screws at
top of the body, turn the upper steel pipe by 180 degrees, and fix the
upper steel pipe with the screws in counter-position.
*Tip: Upon end of installation, keep the machine out of any action
for 2h before starting to use.
3. Water tank usage: You may use the water tank in two ways. I) Direct
use. When the water tank is full, the machine automatically shuts
down and enters the standby state, the LED displays the "Full Water"
signal and the hummer alarms. When the water tank is emptied and

Continuous drainage. As shown in Fig. 3, to restore the performance
of the water tank, you need to take out the water tank, remove the
drain plug, and install the drain pipe. Put the water tank back to its
original position, and the water pipe goes out from the side plate.
*Tip: In continuous drainage, the drainage pipe shall not be set
higher than the water tank.
WARNING:
If the power cord is damaged, it must be replaced by the professional
person from manufacturer, the maintenance department or similar
departments.
Product Introduction
Core Parts: GMCC/GREE rotating compressors adopted, of higher
performance and less power consumption than reciprocating compressor
of identical refrigerating capacity.
Tips: For physiological health of the humanity, protection of furniture and
other items indoors and energy saving, the humidity is recommended to
range from RH50% to 70%, provided no special requirements are made.

Function Description
1. Humidity Control
When room humidity value 3% lower than set, compressor shut
down, fan delay 3 minutes and shut down; and when it's 3% higher
than the humidity value set, both fan and compressor operate.
Note
◊ When the humidity is set at the minimum value, it's defaulted to enter
the continuous dehumidifying mode
◊ Upon fault of the humidity sensor, it turns to the continuous
dehumidifying mode
◊ Upon fault of the coil sensor, it turns to the timing defrosting mode
(See the defrosting mode)
◊ When it's shut down, the fan will be closed 10s later.
2. Protection Function
◊ Once shut down, the compressor takes 3min to start. Quick start is
available for the first power-on.
◊ Power off memory: For abrupt power outage or accidental
unplugging of the plug, the system will automatically archive the
operating state right before the incident, and continue at that state
for the next power-on.
◊ Full water protection: When the water tank is full, the dehumidifier
automatically shuts down and enters the standby state, the indicator
light "Full Water" on and buzzer alarms.
