Please don't connect the dehumidifier on the socket with lower electric rating
than the dehumidifier.
Don't damage or refit the power line. Don't put heavy things or high-temperature
objects on the power line. Don't pull or coil the power line while operating
the dehumidifier.
Please don't catch the power line in the door to avoid damaging it.

sticks or other objects into the air outlet of the dehumidifier, or the fan blade
runs with high speed may cause serious injury.
The water in the tank must be emptied out.
(Eating or using the water remained in the tank on other purposes may cause
disease or accident.)
The dehumidifier must be placed on a smooth and stable surface.
Don't spray or moisten the dehumidifier to avoid electric shock.
Don't use the dehumidifier outdoors. The direct exposure to the sun or rain
may cause it superheated, get an electric shock or fire.
Don't place the objects, such as vases on the dehumidifier.
(If they are overturned, the water enters into the dehumidifier may worsen the electrical
insulation, which may cause electric shock, leakage current or fire.)
Don't use the dehumidifier for other purposes, such as keeping food or
artwork, or it may cause quality deterioration.
Please don't use the dehumidifier in the places may leak oil or hold

Defrosting operation
The room temperature increases during the operation.

Accessory
Installation
Note
The evaporator in the dehumidifier may defrost if it is operated in the room temperature
no more than 15°C. The defrosting device may start up and operate for some time (about 5
minutes) automatically every 30 minutes or even longer.
During the defrosting operation, the dehumidification function and air purification
function may intermit.
Please don't turn off the switch or pull out the power plug of the dehumidifier during the
defrosting operation.
This dehumidifier can't be applicable to keep extreme low temperature.
The purpose of this dehumidifier is to pump off the unpleasant high temperature in daily
life and dry the wet things. But it can't be used to keep extreme low temperature.
This dehumidifier doesn't have cooling function. It will produce heat during the operation
and increase the room temperature to 1 to 4°C. This temperature rise may be very distinct
in the cabinet or other similar spaces. In addition, the door and windows are closed and
other appliances in the room can give out heat as well as the radiation of the sun can raise
the room temperature.
Dehumidifying capacity
The illustration below shows the daily dehumidifying capacity of the dehumidifier. This
capacity is based on the 30°C of room temperature the dehumidifier sets, 80% of relative
humidity and the data when the air outlet is fully open. At different temperatures and relative
humidity, it may have different dehumidifying capacities.
In the same room temperature, the dehumidifying capacity is higher in higher relative
humidity and the dehumidifying capacity is lower in lower relative humidity. In the same
relative humidity, the dehumidifying capacity is higher in higher temperature and the
dehumidifying capacity is lower in lower temperature.
If the dehumidifier is placed in the cabinet, its dehumidifying capacity may highly reduce in
a short period after operating, that is, the humidity in the cabinet has been highly reduced.

If the dehumidifier gets interference from the
household appliances, such as television and
radio cassette player, please keep the
equipment away from the dehumidifier for
over 70cm.

Clean the filter (maintain it every two weeks)
The dehumidifying capacity may reduce while the filter is blocked by dirty matters.
Take out the filter according to the method showed in the figure and clean the dust
with dust collector and put it back to the machine unit.
The dust is usually cleaned with dust collector. If the filter is too dirty, clean it
with the water added with neutral detergent and install it back to the machine
unit after it is dry.
Replace the filter (replace it every half year)
The time of use of the filter is 6 months. Please replace a new filter after using over 6 months.

Phenomenon
Intermittent stop during the operation
Causes
Malfunction disposals
Please check each item first before applying for maintenance:
Make sure the phenomena below happen while the malfunctions
above are not included:
The defrosting or humidity valve of the machine unit may reach a
set value. When the humidity rises again above the set value, the
machine unit may start automatically.
Small dehumidifying capacity
The dehumidifying capacity drops with the room temperature and
humidity. See the illustration above for reference.
The humidity of the room can't reduce
The room area is too big, which is over its application scope.
The door and windows of the room aren't closed.
The machine unit is operated with a kerosene heater (which releases
steam) together.
Unpleasant smell The smell may come from the wall, furniture and other things,
The machine unit makes a sound
during operation.
The sound made by the flowing of the refrigerant may eliminate
or lower automatically while the system operates stably.
Water is in the tank.
Since each machine unit has taken operation test before leaving the
factory, some water remains on the evaporator flows to the water tank.
The FULL indicator light is on. When the water tank is full, the FULL indicator light is on for reminding.
