ENGLISH
Dehumidifier efficiency varies depending on room tempera-
ture and relative humidity.
• A lower temperature and lower relative humidity will reduce the moisture removal rate.
• The compressor operates in dehumidification mode only when the set humidity is lower than the
room humidity.
The operating temperature is 5°C to 32°C.
• The dehumidifier cannot be used at 0°C or below because the dehumidified water could freeze.
• At 32°C or higher, the dehumidifier may stop running automatically to protect itself from over-
heating.
The room temperature increases while the dehumidifier is
running.
• This dehumidifier does not have temperature control functions.
• The dehumidifier generates heat while operating, raising the room temperature by about 2°C or
3°C depending on the usage conditions (room air pressure and room size).
The dehumidification can be restarted after three minutes.
• If you attempt to restart the dehumidifier immediately after stopping it, the compressor will start
running again after about three minutes for product safety reasons.

CHECKLIST BEFORE USAGE 9
ENGLISH
Dehumidification amount changes according to indoor temperature and
relative humidity.
- If the temperature or relative humidity is low, dehumidification amount is decreased.
- Dehumidification is performed with compressor operation only when the desired humidity is
lower than the current humidity.
The product can operate in the temperature boundary of 5°C~32°C.
- At 0°C or less, dehumidified water will freeze, and dehumidification cannot be performed.
- If it is over 32°C, the temperature inside the dehumidifier will rise, and there will be cases of
stopping the operation by protective device activation to avoid excessive usage.
When the dehumidifier is under operation, the indoor temperature will rise.
- Dehumidifier does not have a cooling/heating function.
- Heat is generated during the operation, so the temperature may be increased by about 2°C~3°C
according to the usage conditions (indoor temperature, size of the room).
Operation will restart after 3 minutes.
- If it is restarted right after the stop, the compressor will start about 3 minutes after to protect the
product.
It automatically protects the product during the continuous operation.
If it is operated for 24 hours or more continuously, the compressor will stop automatically to pro-
tect the product, and it will restart after 1 hour.
Please have gap of 30cm or more from the wall.
If it is not ventilated well, the air suction performance will be degraded.
There may be water remaining in the drain water tank at the first time
usage.
There may be water remaining in the drain water tank by the product outgoing inspection to check
the normal operation of the product. It is not a failure.
