Operation and efficiency
Defrosting operation
The evaporator in the dehumidifier may defrost automatically if it is operated in the room
temperature less than 18℃. The defrosting process may start up and operate for some time (about
5 minutes) automatically every 25 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 the dehumidifier is to pump off the unpleasant high humidity in daily life and dry
the wet things. But it can't be used to keep extreme low temperature.
The room temperature increases during the operation.
This dehumidifier doesn't have cooling function. It will produce heat during the operation and
increase the room temperature to 1 to 4℃. 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℃ 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.
