ALWAYS USE A FUSE WITH THE CORRECT CURRENT RATING.

This unit is designed for human comfort. Do not use for applications such as a kennel or nursery to raise animals or plants.

TIPS ON SAVING ENERGY

Below are some simple ways to save energy when you use your air conditioner.

SET THE CORRECT TEMPERATURE

• Setting the thermostat 1°C higher in COOL mode, and 2°C lower in HEAT mode than the desired temperature will result in a 10% saving in electricity.
• Setting the temperature colder than necessary during cooling will result in excess power consumption.
• Make an effective use of the SAVE MODE. (Refer to page 17)

KEEP OUT DIRECT SUNLIGHT AND DRAFTS

• Keeping out direct sunlight when cooling will aid in reducing the power consumption.
• Close the windows and doors when heating and cooling the room.

SET PROPER AIR FLOW DIRECTION

- Set the louvres to obtain the best air circulation.

KEEP FILTER CLEAN

- Keep the filter clean to ensure the most efficient operation.

MAKE MOST OF TIMER

- Make the most of the AUTO SLEEP (TIMER OFF) function.

UNPLUG THE POWER CORD WHEN THE UNIT IS NOT TO BE USED FOR AN EXTENDED PERIOD

- Unplug the power cord when the unit is not to be used for a long period of time. The indoor unit still consumes a small amount of power when it is not operating.

TEST RUN

IMPORTANT OPERATIONAL POINTS

DURING THE AIR CONDITIONER OPERATION

• A built-in protective device may prevent the unit from operating when the ambient temperature is extremely high or low.
• Dew may form on the air outlet when the unit operates continuously in the COOL or DRY mode when the humidity is over 80%.

3-MINUTE PROTECTION

After the unit has been turned off, a protective mechanism prevents it from being turned on again for three minutes.

FAN SPEED

• When the fan speed is set to AUTO in the COOL mode, the fan speed automatically decreases as the room temperature nears the thermostat setting.
• When the room temperature reaches the thermostat setting in the HEAT mode, the compressor stops and the indoor fan changes to the SOFT setting or stops.
• In the DRY mode, the fan speed is controlled automatically.

PREHEATING FUNCTION

In the HEAT operation, the indoor fan may not start for 2-5 minutes after the unit is turned on to prevent the air from circulating before the unit is sufficiently warmed up.

DE-ICING FUNCTION

• When ice forms on the heat exchanger in the outdoor unit during the HEAT operation, an automatic de-icer provides heat for about 2-10 minutes to remove the ice. During de-icing, the inside and outside fans stop operating.
• After de-icing is completed, the unit automatically resumes operation in the HEAT mode.

HEATING EFFICIENCY

• The unit employs a heat pump that draws heat from the outside air and releases it into the room. The outside air temperature therefore greatly affects the heating efficiency.
• If low outside temperatures adversely affect the heating efficiency, use an additional heater.
• It takes time to warm up and heat the entire room because this unit employs a forced air circulation design. To warm up the room in advance, use the timer in the HEAT operation.

MAINTENANCE

Be sure to unplug the power cord from the wall outlet or turn off the circuit breaker before performing any maintenance.

ADDITIONAL NOTES ON OPERATION

THE FOLLOWING ARE NORMAL CONDITIONS FOR THE UNIT.
UNIT DOES NOT OPERATEIf you restart the air conditioner within 3 minutes after turning it off, or change the mode during operation, a protective device will work to shut off the unit for 3 minutes.	LOW NOISEA soft, swishing noise can be heard during operation or immediately after the unit is turned off. This is the sound of the circulating refrigerant.
WARM AIR DOESN'T COME OUTWarm air does not come out of the air outlets in the preheating or the de-icing operation.	WATER VAPOURIn the COOL and DRY operation, water vapour can sometimes be seen coming from the air outlet due to the difference in temperature between the room air and the outlet air.In HEAT operation, water vapour may come out of the outdoor unit during the de-icing operation.
ODORSOdors present in the room, such as those from the carpet or furniture, may be emitted from the unit.	INDOOR UNIT FAN SPEEDWhen using the air swing mode, the speed of the indoor fan may vary slightly as the louvre moves up and down.

BEFORE CALLING FOR SERVICE

If the unit appears to be malfunctioning, check the following points before calling for service.

IF THE UNIT FAILS TO OPERATE

Check to see if the circuit breaker has tripped or the fuse has blown.

IF THE UNIT FAILS TO COOL THE ROOM PROPERLY
Check the filter. If it's dirty, clean it.	Check the outdoor unit to make sure nothing is blocking the air inlet or outlet.	Check whether the thermostat is set properly. If it is set too high in the COOL mode or too low in the HEAT mode, the unit may fail to operate properly.
Make sure all windows and doors are closed tightly. Air entering from outside can prevent the room from cooling sufficiently.	A large number of people in the room can prevent the desired temperature from being reached.	The use of heat-generating appliances in the room will adversely affect cooling efficiency.

IF THE UNIT FAILS TO RECEIVE THE REMOTE CONTROL SIGNAL
Check whether the remote control batteries have become old and weak.	Check whether the remote control batteries are installed in the proper polarity.	Try to send the signal again with the remote control pointed properly towards the unit's receiver window.

PRECAUTIONS FOR INSTALLATION

LOCATIONThe unit may not function well in locations where there is excessive dust, fumes or moisture in the air.REMOVALDo not attempt to remove the unit yourself. Consult your dealer or other qualified service personnel for assistance.
