QUICK START
Dehumidier efciency varies depending on room
temperature and relative humidity.
•A lower temperature and lower relative humidity will reduce the moisture removal rate.
• The compressor operates in dehumidication mode only when the set humidity is lower than the room
humidity.
The operating temperature is 5°C to 32°C.
• The dehumidier cannot be used at 0°C or below because the dehumidied water could freeze.
• At 32°C or higher, the dehumidier may stop running automatically to protect itself from overheating.
The room temperature increases while the dehumidier is
running.
• This dehumidier does not have temperature control functions.
• The dehumidier 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 dehumidication can be restarted after three minutes.
• If you attempt to restart the dehumidier immediately after stopping it, the compressor will start running
again after about three minutes for product safety reasons.

CHECKLIST BEFORE USAGE 9
EN
CHECKLIST BEFORE USAGE
Dehumidication amount changes according to indoor temperature and relative
humidity.
- If the temperature or relative humidity is low, dehumidication amount is decreased.
- Dehumidication 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, dehumidied water will freeze, and dehumidication cannot be performed.
- If it is over 32°C, the temperature inside the dehumidier will rise, and there will be cases of stopping the
operation by protective device activation to avoid excessive usage.
When the dehumidier is under operation, the indoor temperature will rise.
- Dehumidier 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 protect 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 rst 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.
