Dehumidifying cannot be performed
or only a small amount of water is
dehumidified under the condition of
low humidity and low temperature.
Is the dehumidifier used in the
low-humidity and low-temperature
environment ?
1) Dehumidifying (Auto) : Blower fan stops when temperature is 27
℃
or less, and current humidity is –1% of set humidity or less.
2) Intelligent laundry : It stops in a minimum of about 84 minutes and
a maximum of about 12 hours.
3) Deo-dry : It stops in about an hour.
4) Bathroom mildew guard : A minimum of about 4 hours and a maximum
of about 12 hours
5) OFF timer : Is the timer operation selected ?
It stops at the set time.
6) All operation modes:Is the timer operation selected with other
operation mode ? Timer operation has priority over other modes,
so it stops at the set time.
1-6 indicate that the unit is operating normally. Explain that to the
customer.

It is normal.
The unit can operate in a room temperature range of 1-35
℃
.
①
When the room temperature is less than 1
℃
, dehumidified water freezes
and it hinders dehumidifying.
②
When the room temperature is more than 35
℃
, internal temperature of
the unit rises, which activates the protective device.
