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 deﬂ ectors 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 deﬂ ectors 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 deﬂ ectors which eventually may drip to the ﬂ oor, please do not adjust horizontal deﬂ ectors

extremely downward position or vertical deﬂ ectors extremely leftward or rightward position during cool operation for a long

time.

Also, do not adjust the vertical deﬂ ectors 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 deﬂ ectors of the unit.

NOISE

In a quiet environment during the starting or stopping the operation, phenomena like ﬂ owing 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-ﬁ lter 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-ﬁ lter will reduce the air

volume and the cooling efﬁ ciency.

To prevent from wasting electric

energy, please clean the pre-ﬁ lter

every 20 days.

Please Adjust Suitable Temperature

For Baby And Children

Please pay attention to the

room temperature and air ﬂ ow

direction when operating the

unit for baby, children and old

people who have difﬁ culty 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.

is very dirty, wash it with detergent and rinse properly with water. Dry

the pre-ﬁ lter with soft cloth and do not expose it to heat or under direct

sunlight.

● Install the pre-ﬁ lter by ﬁ tting the top hooks and then hook the bottom of

the pre-ﬁ lter.

● 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.
