White mist emerging from the indoor unit
Compressor protection
The compressor cannot restart for 3 minutes after it stops. Anti-cold air (cooling and heating models only)
The unit is designed not to blow cold air on HEAT mode, when the set temperature has not been reached and the indoor heat exchanger is in one of the following three situations:
A white mist may be generated due to a large temperature dierence between air inlet and air outlet in COOL mode in places with high relative humidity.
A white mist may be generated due to moisture created in the defrosting process when the air conditioner restarts in HEAT mode after defrosting.
A) Heating has just started B) The unit is defrosting C) The unit is heated at a low temperature
The indoor or outdoor fan stops running when defrosting (cooling and heating models only).
Frost may be generated on the outdoor unit during a heat cycle when the outdoor temperature is low and the humidity is high, resulting in lower heating eciency in the air conditioner.
Under these conditions, the air conditioner will stop heating operations and start defrosting automatically.
The time to defrost may vary from 4 to 10 minutes, depending on the outdoor temperature and the amount of frost buildup on the outdoor unit. Auto-restart (some models) In case of power failure, the system will immediately stop. When power returns, the operation light on the indoor unit will flash. To restart the unit, press the ON/OFF button on the remote control. If the system has an auto-restart function, the unit will restart with the same
Noise coming from the air conditioner
You may hear a low hissing sound when the compressor is running or has just stopped running. This is the sound of the refrigerant owing or coming to a stop.
You may also hear a low "squeaking" sound when the compressor is running or has just stopped running. This is caused by heat expansion and cold contraction of the plastic parts in the unit when the temperature is changing.
A noise may be heard due to the louver restoring itself to its original position when power is rst turned on.
Dust blowing out from the indoor unit.
This happens when the air conditioner has not been used for a long time or during its rst use.

The air conditioner turns to FAN ONLY mode from COOL or HEAT (for cooling and heating models only) mode.
When the indoor temperature reaches the set temperature, the compressor will stop automatically and the air conditioner will turn to FAN ONLY mode. The compressor will start again when the indoor temperature rises in COOL mode or falls in HEAT mode to the set point.
Droplets of water may form on the surface of the indoor unit when cooling occurs in relatively high humidity (dened as higher than 80%). Adjust the horizontal louver to the maximum air outlet position and select HIGH fan speed.
Heating mode (for cooling and heating models only)
The air conditioner draws in heat from the outdoor unit and releases it via the indoor unit during heating. When the outdoor temperature falls, heat drawn in by the air conditioner decreases accordingly. At the same time, heat loading of the air conditioner increases due to the larger dierence between the indoor and outdoor temperatures. If a comfortable temperature cannot be achieved by the air conditioner alone, it is recommended that you use a supplementary heating device.
Lightning or a car wireless telephone operating nearby may cause the unit to malfunction. Disconnect the unit from its power source and then reconnect the unit with the power source. Push the ON/OFF button on the remote control to restart operation.
Energy-Saving Tips
DO NOT
When the unit is cooling, close curtains to avoid exposure to direct sunlight.
Keep doors and windows closed to keep cool or warm air in the room.
DO NOT
Set a timer and use the built-in SLEEP/ECONOMY mode if applicable.
If you don’t plan to use the unit for a long time, remove the batteries from the remote control.
Clean the air filter every two weeks.
Adjust louvers properly and avoid direct airflow.
set the unit to excessive temperature levels.
place objects near the unit's air inlet or outlet.

Operation Mode Selection
When two or more indoor units are operating simultaneously, make sure the modes do not conict with each other. HEAT mode claims precedence over all other modes. If the unit initially operated in HEAT mode, the other units can operate in HEAT mode only. For example: If the unit initially operated in COOL (or FAN) mode, the other units can operate under any mode except HEAT. If one of the units selects HEAT mode, the other operating units will stop operation and diplay ”--” (for units with a display window) or the auto and operation indication light will ash rapidly, the defrost indication light will turn o, and the timer indication light will remain on (for units without a display window). Alternatively, the defrost and alarm indication light (if applicable) will light up, or the operation indication light will ash rapidly, and the timer indication light will turn o (for the oor and standing types).
Optimal Operation
To achieve optimal performance, please note the following:
Adjust the direction of the airow so that it does not blow directly on people.
Adjust the temperature to achieve the highest possible level of comfort. Do not adjust the unit to excessive temperature levels.
Close doors and windows in COOL mode or HEAT mode.
Use the TIMER ON button on the remote control to select a time for the air conditioner to start.
• Do not place any object near the air inlet or outlet,
as the eciency of the air conditioner may be reduced and it may stop running.
• Clean the air lter periodically. Otherwise,
cooling or heating performance may be reduced.
• Do not operate the unit with the horizontal
louver in the closed position.
Manual Operations
and Maintenance
Maintenance
If you plan to leave the unit idle for a long time, perform the following tasks:
1. Clean the indoor unit and the air lter.
2. Select FAN ONLY mode and let the indoor fan run for a time to dry the inside of the unit.
3. Disconnect the power supply and remove the battery from the remote control.
4. Check the components of the outdoor unit periodically. Contact a local dealer or a customer service center if the unit requires servicing.
NOTE: Before you clean the air conditioner, be sure to switch o the unit and disconnect the power supply plug.
Suggestion: For units that feature an electric heater, when the outside ambient temperature is below 32° F (0° C), it is strongly recommended that you keep the machine plugged in to guarantee smooth operation.
When the air conditioner is to be used again:
Use a dry cloth to wipe o the dust accumulated on the rear air intake grille to avoid the dispersion of the dust from the indoor unit.
Check that the wiring is not broken o or disconnected.
Check that the air lter is installed.
Check if the air outlet or inlet is blocked after
the air conditioner has not been used for a long time.

overloading. The unit cannot be restarted within 3 minutes of being turned o.
Cooling and heating models: If the operation light and PRE-DEF (Pre-heating/ defrost) indicators are lit up, the outdoor temperature is too cold and the unit’s anti-cold wind is activated to defrost the unit.
In cooling-only models: If the “fan only” indicator is lit up, the outdoor temperature is too cold and the unit’s anti-freeze protection is activated to defrost the unit.
The unit changes its setting to prevent frost from forming on the unit. Once the temperature increases, the unit will start operating again.
The set temperature has been reached, at which point the unit turns o the compressor. The unit will resume operating when the temperature fluctuates again.
In humid regions, a large temperature dierence between the room’s air and the conditioned air can cause a white mist.
When the unit restarts in HEAT mode after defrosting, a white mist may be emitted due to moisture generated from the defrosting process.
A squeaking sound is heard when the system is OFF or in COOL mode. The noise is also heard when the drain pump (optional) is in operation.
A squeaking sound may occur after the unit is run in HEAT mode due to expansion and contraction of the unit’s plastic parts.

SYSTEM OPERATION
COOLING OPERATION
How it works:
In cooling mode, your indoor unit will absorb heat from the room, then the outdoor unit will discharge the heat to the outdoors. The cooling capacity decreases as the outdoor temperature increases. This causes the unit to work harder and longer to hold the selected room temperature.
Indoor Coil Freeze Protection:
Frost may form on the indoor coil during cooling operation when the outdoor temperature is below 50° F (10° C). Prolonged operation may cause ice to form on the indoor coil and block airow. If the indoor unit microcomputer detects ice on the indoor coil, it will stop the compressor to defrost the coil and protect the unit.
HEATING OPERATION
How it works:
In heating mode, your outdoor unit will absorb heat from the outdoor ambient, then the indoor unit will discharge the heat to the room. The heating capacity will decrease as the outdoor temperature decreases.
During extremely cold outdoor temperatures, you may need an additional heating source to supplement the heating output.
Defrost Function:
In heating mode, frost may form on the outdoor coil during humid and low outdoor temperature conditions. Prolonging operation may cause ice to form on the outdoor coil and block airow. This will reduce the unit's, heating capacity.
If the microcomputer detects ice on the outdoor coil, it will switch automatically to defrost mode to melt the ice and clear the coil. During defrost mode, heating will be discontinued and the indoor unit will ash the defrost indicator. The compressor will continue to run, but the indoor and outdoor fans will stop. It is normal to see steam or vapor coming from the outdoor unit in defrost mode. Defrost mode will terminate 12 minutes after the initiation of the defrost cycle or when the outdoor coil temperature is 50° F (10° C) or greater.
ENERGY-SAVING TIPS
1. Relaxing room temperature at night is OK: During the nighttime
hours, you don’t require the same level of conscious cooling or heating. Try using Sleep Mode to gradually relax the room temperature and allow the unit to run less and save energy.
2. Curtains and shades: In the summer, you need to block the effects of the sun. Close window curtains and shades on the south and west sides of your home to help block solar heat. In winter, the sun is your friend. Open curtains and shades to allow solar heat into your room.
3. Close doors: If you don’t need to heat and cool your entire home,
confine the heating and cooling to one room by closing doors. Limit the space you’re heating and cooling to the specified capability of the unit.
4. Service the unit: You may need only some basic maintenance.
The outdoor unit will greatly benefit from a good hosing out, especially in treed areas where seeds and other debris can stick to coil fins and make the unit work up to 15% harder.
5. Rearrange the room: If furniture obstructs airflow, you could be heating
and cooling the back of a chair or the front of a sofa instead of actual living space. Use the swing louvers to help point the air in the right direction for the room. Remove or rearrange obstacles that block airflow.
6. Lighting: Turning lights off can help reduce heat. Each light bulb is
a tiny heater. Your air conditioner wastes energy overcoming the heat from your lights to reach and hold your desired room temperature.
7. Is anyone home? If possible, while you’re away, turn your unit to Auto
mode and make sure windows and drapes are closed. Although the room temperature will be uncomfortable for a few minutes when you come home, the unit will bring the room back to your desired temperature in no time.
8. Don’t forget the fan: The fan is much llike a car: the faster it runs, the
more energy it uses. Sometimes we need the car to go fast, but slow is good enough most of the time. Try saving money by using the comfortable and quiet low fan speed as much as possible.
