Precautions
The dehumidifier should not operate at a humidity setting higher than the ambient humidity.
When the water full indicator is on, pour out the water in the water tank. Then put the
emptied water tank back to its original position, and the machine can continue to be used.
When the machine stops, wait at least 3 minutes before restarting to avoid damage to the
compressor.
The usable ambient temperature range is 5~35 degrees.
When the dehumidifier is operating, the operating compressor will generate heat,
which will make the room temperature higher, which is a normal phenomenon.
When you need to move this product, please lift it facing the front of the product.
Drain indication
Drained water can be stored in a tank or externally drained using a hose.
Use of the water tank
The water dehumidified by this machine will automatically flow into the
water tank. When the water is full, the indicator light will be on. When the
water tank is full, the whole machine will stop running. Please empty the
water in the water tank.
