●
A circuit breaker should be installed depending on the mounting site of the unit. Without a circuit
CAUTION
breaker, the danger of electric shock exists.
●
Do not install near location where there is Á ammable gas. The unit may catch À re if Á ammable gas
leaks around it.
●
If drain pan is used, please ensure that when installing the drain hose, water is able to Á ow freely
without any obstruction.

AUTO SWING
●
When the AUTO SWING switch is turned to "ON" position, the vertical deÁ ectors automatically oscillate right and left
sweeping the cold air alternately to obtain comfortable cooling.
●
The vertical deÁ ectors will stop to swing when the AUTO SWING switch is turned "OFF"
OPERATION MODE SELECTOR DIAL

THERMOSTAT DIAL
Setting the desired room temperature. Turn the dial further clockwise for cooler indoor temperature.
CAUTIONS
●
Do not set the dial to "TEST" for normal usage. This setting is only for technician. If the unit
is operate at "TEST" for normal use, it may cause the evaporator frosted and consequence
of no cooling, noisy and water leakage may be found.
●
If the evaporator is found frosted, it means the temperature at evaporator is too low. Please
turn the dial anti-clockwise and check if any obstacle in front of air outlet and inlet like curtain.
●
When the compressor stops, please wait 3 minutes before turning the dial clockwise.
AIR DEFLECTORS
VERTICAL DEFLECTORS
Vertical deÁ 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.
CAUTIONS
To avoid dew forming on the deÁ ectors which eventually may drip to the Á oor, please do not adjust horizontal deÁ ectors
extremely downward position or vertical deÁ ectors extremely leftward or rightward position during cool operation for a long
time.
Also, do not adjust the vertical deÁ ectors position by hand or any other object.
AIR EXHAUST LEVER
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.
AIR PURIFYING FILTER
Always stop the operation before installing the air purifying À lter.
1. Pull and remove the suction grille
Air purifying À lter is washable and can be use for 1 year time. Type number for this air purifying À lter is <SPX-CFH8W>.
Please use this number for ordering when you want to renew it.
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 deÁ ectors of the unit.
NOISE
In a quiet environment during the starting or stopping the operation, phenomena like Á 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-À lter and the evaporator regularly must be
cleaned to reduce the odor.
THE IDEAL WAYS OF OPERATION
Install curtain or blinds
Suitable Ro

Warning

waste of electric power.
Do Not Forget To Clean The Pre-Filter
Dusty pre-À lter will reduce the air
volume and the cooling efÀ ciency.
To prevent from wasting electric
energy, please clean the pre-À lter
every 20 days.
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.
HORIZONTAL DEFLECTORS
Horizontal deÁ ectors at both sides of the outlets can
be set to direct discharge air upward, downward or
forward direction.
