Note the following phenomena are normal under standard operating conditions Phenomenon Operation stops occasionally Dehumidified volume is small Humidity remains high Bad smell during operation Sound is produced from unit The buzzer sounds Reason The unit is defrosting (See the page5 ) 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). 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). While the humidity levels are high mould can form. When the unit is operating it will raise area temperatures and increase air flow. Circulation of the refrigerant may cause sound until levels have stablised. The buzzer sound when the water tank is full of water. Please record the following items.
