Operation considerations

Defrost operation The evaporator within the dehumidifier can frost over during normal operation (at temperatures of approx.15℃ or less). The unit automatically removes the frost at intervals of approximately 30 minutes or more (for a duration of approximately 5 minutes).While this unit performs this cycle both the dehumidifying function and the air cleaning function are suspended ● Do not turn off or disconnect the unit during the defrosting operation.

This dehumidifier is not suitable for sustained lowering of humidity (approx.50% or less) This dehumidifier is designed to remove uncomfortable levels humidity in daily life and for enhanced indoor drying. It is not suitable for sustaining very low humidity levels

Room temperature rises during dehumidifier operation. This dehumidifier does not have a cooling function. It produces heat during normal operation which will have an effect on the surrounding environment. Further more any temperature changes will be respective to the size of the room it is located in. Therefore appropriate considerations should be taken when deciding how and where to locate this unit.

Note the following phenomena are normal under standard operating conditions

Phenomenon Reason Operation stops

occasionally

The unit is defrosting (See the page5 )

Dehumidified

volume is small

Dehumidified efficiency is less when the room temperature is low (see the page 6). The unit

stops dehumidifying because the humidity in a room drops to 60% or less while in

“Automatic” mode. (See page 5).

Humidity remains

high

The room size may be too large .(see the page5)

Doors or windows may be opened and/or closed frequently.(see the page5)

The dehumidifier is used to close to moisture emitting devices (some types of heaters).

Bad smell during

operation

While the humidity levels are high mould can form. When the unit is operating it will raise

area temperatures and increase air flow.

Sound is produced

from unit

Circulation of the refrigerant may cause sound until levels have stablised.

The buzzer sounds The buzzer sound when the water tank is full of water.
