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.

Preparation for use
Installation of dehumidifier air filter.
1. Remove the back cover.
Use the indents to lift away cover
2. Remove the filter holder from the back cover.
Filter holder is clipped to the inside of the cover.
The filter holder then unclips and is ready for the filter
3. Installing/changing filter.
Remove the filter out of its packaging and put in
the filter holder. Repeat in reverse step 2, placing
the filter holder on the clips of the back cover with the flat surface
facing up, and set the holder to the four catches in the
cover (with the convex portions of the holder upward).
Replace the cover securely, pressing its perimeter making sure
It is flush
● In case of incorrect alignment of the filter, the cover cannot be correctly replaced.
____________________________________________________________________________
Replacing the cover.
To ease installation, install
one side of the cover first, and
then the other.
____________________________________________________________________________
Water tank orientation.
NB. The dehumidifier will not operate if the water tank
Is full of water or it is not located correctly.
How to remove
Draw the water tank gently toward you by holding the
Concave sides of the tank.
How to install
Push the tank horizontally and gently. The
handle folds down flat within the take.
Take care, not to damage to level float in either operation

Emptying water from a water tank
1. Remove water tank from the dehumidifier and fold up handle
2. Tilt the tank to the direction as shown. and slowly empty
the water out of the tank.
3. Set the tank in the dehumidifier taking care not to damage the
level float.
Note
As part of the dehumidifiers’ operation, water is
collected in the water tank.. Once the tank is full,
the dehumidifier stops automatically and the
buzzer sounds.
The buzzer will sound for 10 seconds while the
tank is removed for emptying.
For continuous draining, see the page 16.

Caution
Stopping operation
Press “power” switch again.
● The mode select indicator will go out and unit will shut down.
● Once the unit has stopped, close any flaps and remove and dispose of any collected water.
Buzzer
Be sure to allow free airflow movement though the unit. If the unit does not have sufficient air movement around
it, overheat protection devices will stop the dehumidifier from working properly.
Due to the nature of this device the dehumidifying operation commence approximately 3 minutes after the unit is
first connected or restarted after a power failure.
Immediately after a power failure, the “Automatic” mode lamp will flash. Press the “Power” switch to restart the
units’ operation
The Efficiency of the dehumidifier is dependant on air flow around the unit. For optimum efficiently, try to avoid
excessive opening and closing of windows and doors.
For the best performance, operate the dehumidifier under the normal operating temperatures. For safety purposes
the dehumidifying operation will stop automatically and change to air cleaning when the ambient temperature
exceeds approx. 36℃.
Initial circulation of refrigerant may cause sounds from within the dehumidifier when the unit is first started.
However after the circulation is stable, the sound will diminish.
To change the timer setting
press “timer select” Switch
until desired time is
Whenever a function is selected the buzzer will sound indicating a change in operation.
To stop the timer operation To cancel the timer operation
Press “Power” Switch
Note:
Press “timer Select ”Switch
The timer lamp will go off.
Notes
●Except for “Continuous” mode operation, the timer setting will be cancelled whenever the
“Mode” switch is pressed. Set the timer again after pressing “Mode” switch, if necessary.
●The timer stops when the water tank is full of water. After the tank is emptied, the timer will
start.

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.
