TEMPORARY SWITCH
Use the temporary switch for start or stop operation when operation cannot be done with the remote controller.
By pressing the temporary switch, [use non-conductor stick (for example: toothpick),] the operation will follow previous
operation mode.
When the operation is done using the temporary switch, after the power source is turned off and is turned on again, the
operation is done in automatic mode.
AIR DEFLECTORS
Vertical deflectors at both sides of outlets can be set to
either auto-swing or static position to direct discharge air
rightward, leftward or forward direction.
Horizontal deflectors at both sides of the outlets can
be set to direct discharge air upward, downward or
forward direction.
VERTICAL DEFLECTORS HORIZONTAL DEFLECTORS
To avoid dew forming on the deflectors which eventually may drip to the floor, please do not adjust horizontal deflectors
extremely downward position or vertical deflectors extremely leftward or rightward position during cool operation for a long
time.
Also, do not adjust the vertical deflectors position by hand or any other object.
!
CAUTIONS
AIR EXHAUST LEVER
WASABI AIR PURIFYING FILTER
Set the air exhaust lever to the down ( OPEN) position for air ventilation in
the room. The air exhaust lever should normally be kept in up ( CLOSE)
position during cooling operation and in the case of typhoon.
NOTES ON OPERATION
TEMPERATURE AND HUMIDITY
Avoid to use the room air conditioner for cooling operation when the outside temperature is below 21°C (70°F). Recommended
operation humidity should be below 80%. Continuous operation at over 80% humidity (indoor) will cause some dews form
on the outlet grille and deflectors of the unit.
NOISE
In a quiet environment during the starting or stopping the operation, phenomena like flowing sound of refrigerant in the
refrigerating cycle and rubbing noise from the fan casing may occasionally occur, but this is normal for the operation.
Water will be condensed on the evaporator coil and collected in the bottom tray, it is picked up by the condenser fan and
blown onto the condenser coil, this creates a “splashing” sound which is normal.
ODOR
The odor will possibly be emitted from the room air conditioner especially at the starting of operation and in a high
humidity condition. This is not abnormal phenomena because of the various kind of odors emitted by smoke, food stuffs,
cosmetics and others which may stick to the room air conditioner. So, the pre-filter and the evaporator regularly must be
cleaned to reduce the odor.
THE IDEAL WAYS OF OPERATION
Suitable Room Temperature
Warning
Freezing temperature
is bad for health and a
waste of electric power.
!
Install curtain or blinds
It is possible
to reduce heat
entering the room
through windows.
Ventilation
Caution
Do not close the room for a long period of
time. Occasionally
open the door and
windows to allow the
entrance of fresh air.
!
Do Not Forget To Clean The Pre-Filter
Dusty pre-filter will reduce the air
volume and the cooling efficiency.
To prevent from wasting electric
energy, please clean the pre-filter
every 20 days.
Please Adjust Suitable Temperature
For Baby And Children
Please pay attention to the
room temperature and air flow
direction when operating the
unit for baby, children and old
people who have difficulty in
movement.
FOR USER’S INFORMATION
The Air Conditioner And The Heat Source In The Room
Caution
If the amount of heat in the room is above the cooling capability of the air conditioner (for
example: more people entering the room, using heating equipments and etc.), the preset
room temperature cannot be achieved.
!
When Lightning Occurs
Warning
To protect the unit during lightning, please stop operating the unit and remove the plug
from the socket.

●Secure tightly the cabinet with screws to the frame. Otherwise there may be danger of the air conditioner dropping.
●Please keep the recommended installation dimensions. Otherwise waterdrops or malfunction may occur.
!
CAUTIONS
POWER SOURCE
●Check the capacity of wiring and power outlet. The power outlet should be used exclusively for the air conditioner. Do
not use it with other appliances. Any wiring must follow the national wiring regulation.
●Ground the air conditioner to prevent danger of electric shock.
●Connect the air conditioner with power source securely.
●Use a fuse as below:

CAUTION
When using operation of auto swing function, if the vertical deflector swing angle is incomplete, please turn the deflector manually to
the utmost left angle. An abnormal sound will occur when adjusting the vertical deflector. This sound indicates that the engagement of
gear is in position and does not affect the operation.
When raining, rain water will enter the outdoor side. An abnormal sound will occur during operation of unit in raining conditions and
approximately 10 minutes after rain stop. This will not affect the performance or liability of the room air conditioner.

PRE-FILTER
If the pre-filter is clogged with dust, the air flow volume will be decreased and resulting in poor cooling performance, and
increased operating noise. Be sure to clean the filter about every 20 days.
1 Remove the suction grille by pulling the bottom corner and slightly lift up the
suction grille.
2 - 3 Pull downward to unhook the suction grille and remove the suction grille.
●Lift and unhook the bottom of the pre-filter and remove it.
●Remove dust from the pre-filter by using a vacuum cleaner. If the pre-filter
is very dirty, wash it with detergent and rinse properly with water. Dry
the pre-filter with soft cloth and do not expose it to heat or under direct
sunlight.
●Install the pre-filter by fitting the top hooks and then hook the bottom of
the pre-filter.
●Attach the suction grille back to its place by hooking at the top side to
the front cover, then gently push at bottom corner.
Clean the front cover and suction grille with a soft dry cloth. When it is excessively dirty, wipe it with a soft cloth dampened
with mild soap, then wipe it again thoroughly with a soft dry cloth.
The suction grille can also be removed and be washed with water and mild soap. Remove the suction grille in the
following manner.
1 Remove the suction grille by pulling the bottom corner
and slightly lift up the suction grille .
2 - 3 Pull downward to unhook the suction grille and remove
the suction grille.

1Is the power cord loosened or unplugged?
2Is the fuse blown out or the circuit breaker tripped?
3Is the voltage normal?
4Is the main switch set to “OFF” position?
1Is the pre-filter covered with heavy dust?
Clean pre-filter and replace it.
2Is the temperature setting correctly?
3Is the sunlight fall directly in the air conditioner?
4Is the air flow on the rear side (outdoor) blocked?
Leave a space of 900 mm (3 feet) behind the rear side of air conditioner.
5The doors or windows may be opened widely or there are other sources of heat in
the room.
6Is the ventilation damper opened?
Symptom Check
If the power supply cord is damaged, it must be replaced by the manufacturer, its service agent or similiarly qualified
persons in order to avoid a hazard.
CAUTION
!
Remove all the shipping parts before installation and consult an authorised dealer concerning installation requirements,
otherwise may damage the air conditioner.
LOCATION
