THERMOSTAT
To set the desired room temperature, rotate the
thermostat knob to the desired setting. After
the set temperature is achieved the thermostat
will automatically start and stop the compressor
in order to maintain the desired set temperature.
Rotate the thermostat knob clockwise for
higher cool settings. Higher cool settings will
provide lower room temperature. Rotate the
thermostat knob anticlockwise for lower
cool settings. Lower cool settings will provide
higher room temperature.
Thermostat
The thermostat is used to set the desired room
temperature when the unit is being operated in
the COOL MODE.
NOTE:
1. After rotate the thermostat knob to adjust the cool settings
during operation in cool mode, do not rotate it again in 3 minutes
otherwise the fuse may blow due to an overload of the unit.
AUTO SWING
OFF ON
AUTO SWING
Horizontal air flow adjustment (automatically)
When the AUTO SWING switch is turned to ON
position, the vertical louvers automatically oscillate
right and left sweeping the cold air alternately to
obtain comfortable cooling. The vertical louvers will
be stopped at any position when the AUTO SWING
switch is turned OFF .
2. Between 9~12 set points is the lowest temperature operation
mode, 12 set point is TEST
MODE.
Caution: TEST MODE is designed for factory testing only,
evaporator freeze up may occur when unit continues operating
at TEST MODE,DO NOT SELECT TESTMODE DURING
NORMAL OPERATION!
OPERATION INSTRUCTION
COOLER
TEST MODE

The air filter behind the inlet grille should be checked and
cleaned at least once every 2 weeks (or as necessary) to
maintain optimal performance of the air conditioner.
Air Filter
Grasp the right of the control panel cover and
pull it upwards to open it .
Close the control panel cover and press the
right of the cover again until it snaps into the
locked position.
To adjust vertical air flow direction of the up or low horizontal
louvers, adjust any one of the up or low horizontal louver blades.
Manual vertical air flow adjustment
Always keep the top or bottom blades in horizontality. This can
prevent water drops condensed on the front panel of the unit.

Vent Control
The vent control is located above the control panel. The operation method is different
on different models (see the following figures).
For maximum cooling efficiency, CLOSE the vent. This will allow internal air circulation.
OPEN the vent to discharge stale air.
CLOSE VENT OPEN
To open the vent, pull the lever toward
To close it, push it in.
To open the vent, set the lever to the right position
To close it, set the lever in the left position.
CLOSE OPEN
NEVER operate the air conditioner without the
air filter, as dust/dirt particles can cause
equipment failure.

1. Remove the rubber plug from the bottom of the cabinet and
attach to the back drain hole.
2. Take out the drain tray and screws (which are provided with
the air conditioner accessory).
3. Install the drain tray at the bottom of the unit and secure with
screws provided.
4. Connect the drain hose to the outlet located at one side of the
drain tray. You can purchase the drain hose or tubing locally to
satisfy your particular needs .
Suggestion: To ensure the condensed water drain off
smoothly, always keep the drain outlet of the the drain tray
downward when install the drain tray.
See the following procedures to perform bottom drainage:
If you choose non-drainage,both the bottom and the back drain hole of the unit should be
inserted with the rubber plug.

How to remove the air filter
1. Hold the tabs under the front panel, then uplift it outwards,
and remove the front panel.
2. Pinch the handle under the air filter and make the air filter
arched, remove it from the slot from underside to upside.
3. Clean the filter with warm water. The water
O
should be below 40 C to prevent distortion of the filter.
4. Rinse off and gently shake off excess water from the
filter. Allow the filter to dry before re-install it. To prevent
distortion of the filter, do not dry it in direct sunlight.

1. To avoid vibration and noise, make sure the unit is installed securely and firmly.
2. Install the unit where the sunlight does not shine directly.
If the unit is installed under direct sunlight, build an awning to shade the cabinet.
3. There should be no obstacle, such as a fence or wall, within 50cm from the back of the
cabinet because it will prevent heat radiation of the condenser.
Restriction of outside air will greatly reduce the cooling efficiency of the air conditioner.
4. Install the unit a little obliquely outward not to leak the condensed water into the room
(about 10mm with level).
5. Install the unit with its bottom portion 75~150cm above the floor level.
6. The power cord must be connected to an independent circuit. The yellow/green
wire must be earthed.

does not cool as
it should
Air conditioner
does not work
Air conditioner
freezing up
Problem Possible Causes What To Do
The air conditioner is
unplugged.
Make sure the air conditioner plug is pushed
completely into the outlet.
Please review the chart first before you call for service.
Normal Operation
You may hear a pinging noise caused by water being picked up and thrown against the
condenser on rainy days or when the humidity is high.
You may hear the thermostat click when the compressor turns on and off.
Water will be collected in the base pan during high humidity or on rainy days .The water may
overflow and drip from the outdoor side of the unit.
The fan may continue operation when the compressor is off.
The fuse is blown/circuit
breaker is tripped.
Check the house fuse/circuit breaker box and
replace the fuse or reset the breaker.
Power failure.
If power failure occurs, switch off and disconnect
/unplug the power cord. When power is restored,
reconnect (plug in) the power cord, switch on the
power and wait 3 minutes to restart the air
conditioner to prevent tripping of the compressor
overload.
Airflow is restricted .
Make sure there are no curtains, blinds, or
furniture blocking the front of the air conditioner.
Clean the filter at least every 2 weeks.
See the operating instruction section.
When the air conditioner is first turned on, it takes
some time for the room to cool down.
Check for open furnace floor registers and cold
air returns.
Set the air conditioner's vent to the closed position.
See "Air conditioner freezing up" below.
The air filter is dirty.
The room was hot.
Cold air is escaping.
Cooling coils have iced up.
Ice blocks the air flow and
stops the air conditioner
from cooling the room.
Set the fan at MED or HIGH until the ice melts.
