Features

• Protection of the air conditioner Compressor protection

  • The compressor cannot restatr 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 indoor heat exchanger is in one of the following three situations and the set temperature has not been reached.

  • A. When heating has just started.
  • B. During defrosting.
  • C. Low temperature heating.
    The indoor or outdoor fan stop running when defrosting (cooling and heating models only).

• Defrosting (cooling and heating models only)

  • Frost may be generated on the outdoor unit during a heat cycle when outdoor temperature is low and humidity is high resulting in lower heating efficiency 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 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 using the same settings.

• White mist emerging from the indoor unit

  • A white mist may be generated due to a large temperature difference between air inlet and air outlet on 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 operation after defrosting.

• Noise coming from the air conditioner

  • You may hear a low hissing sound when the compressor is running or has just stopped running. This sound is the sound of the refrigerant flowing 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 tempera 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 first 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 first use.

• Smell emitting from the indoor unit

  • This is caused by the indoor unit giving off smells permeated from building materials, furniture or smoke.

• The air conditioner turns to FAN ONLY mode from COOL or HEAT mode (for cooling and heating models only)

  • When the indoor temperature reaches the set temperature setting, the compressor will stop automatically, and the air conditioner turns to FAN only mode. The compressor will start again when the indoor temperature rises on COOL mode or falls on 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 (defined as high 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 larger difference between indoor and outdoor temperature.
  • If a comfortable temperature cannot be achieved with the air conditioner alone, it is recommended that you use a supplementary heating device. Lightning or a car wireless telephone operating neraby may cause the unit to malfunction. Disconnect the unit from its power source and then re-connect the unit with the power source again. Push the ON/OFF button on the remote controller to restart operations.

Energy Saving Tips

• DO NOT set the unit to excessive temperature levels.
• While cooling, close the curtains to avoid direct sunlight.
• Doors and windows should be kept closed to keep cool or warm air in the room.
• DO NOT place objects near the air inlet and outlet of the unit. This will reduce the efficiency of the unit.
• 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. A dirty filter can reduce cooling or heating efficiency.
• Adjust louvers properly and avoid direct airflow.

Manual Operation and Maintenance

Operation mode selection

While two or more indoor units are simultaneously operating, make sure the modes do not conflict with each other. The heat modes claims precedence over all other modes. If the unit initially started to operate in HEAT mode, the other units can operate in HEAT mode only. For example: If the unit initially started operates under COOL (or FAN) mode, the other units can operate under any mode except HEAT. If one of the unit selects HEAT mode, the other operating units will stop operation and display “–” (for units with display window only) or the auto and operation indication light will flash rapidly, the defrost indication light will turn off, 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 flash rapidly, and the timer indication light will turn off (for the floor and standing type).

Maintenance

If you plan to leave the unit idle for a long time, perform the following tasks

1. Clean the indoor unit and air filter.
2. Select FAN ONLY mode and let the indoor fan run for a time to try the inside of the unit.
3. Disconnect the power supply and remove the battery from the remote control.
4. Check components of the outdoor unit periodically. Contact a local dealer of a customer service centre if the unit requires.

NOTE: Before you clean the air conditioner, be sure to switch off the unit and disconnevy the power supply plug.

Optimal operation

To achieve optimal performance, please note the following

• Adjust the direction of the air flow so that it is not blowing 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 controller to select time you want to start your air conditioner.
• Do not place any object near the air inlet or air outlet, as the efficiency of the air conditioner may be reduced and the air conditioner may stop running.
• Clean the air filter periodically, otherwise cooling or heating performance may be reduced.
• Do not operate unit with horizontal louver in closed position.

SUGGESTION: For units that feature an electric heater, when the outside ambient temperature is below 0ºC (32ºF), it is strongly recommended that you to keep the machine plugged in so as to guarantee smooth operation.

When the air conditioner is to be used again

• Use a dry cloth to wipe off the dust accumulated on the rear air intake grille in order to avoid the dust being dispersed from the indoor unit.
• Check that the wiring is not broken off or disconnected.
• Check that the air filter is installed.
• Check if the air outlet or inlet is blocked after the air conditioner has not been used for a long time.

Troubleshooting

CAUTION: If one of the following conditions occurs, switch off the power supply immediately and contact your dealer for further assistance.

• The operation light continues to flash rapidly after the unit has been restarted.
• The remote control buttons do not work.
• The unit continually trips fuses or circuit breakers.
• A foreign object or water enters the air conditioner.
• Other abnormal situations.

Common Problems

The following symptoms are not a malfunction and, in most situations, will not require repairs.

Unit does not turn on when pressing ON/OFF button

| The unit has a 3-minute protection feature that prevents the unit from overloading. The unit cannot be restarted within three minutes of being turned off)
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 in order 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 in order to defrost the unit.

The unit changes from COOL mode to FAN mode

| The unit may change 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 off the compressor. The unit will continue operating when the temperature fluctuates again.
The indoor unit emits white mist| In humid regions, a large temperature difference between the room’s air and the conditioned air can cause white mist.
Both the indoor and outfoor units emit white mist| When the unit restarts in HEAT mode after defrosting, white mist may be emitted due to moisture generated from the defrosting process.

The indoor    unit          makes noises

| 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 running the unit in HEAT mode due to expansion and contraction of the unit’s plastic parts.
Issue| Possible Causes
---|---

Both the indoor unit and outdoor unit make noises

| A low hissing sound during operation: This is normal and is caused by refrigerant gas flowing through both indoor and outdoor units.
A low hissing sound when the system starts, has just stopped running, or is defrosting: This noise is normal and is caused by the refrigerant gas stopping or changing direction.
The outdoor unit makes noises|

The unit will make different sounds based on its current operating mode.

Dust is emitted from either the indoor or outdoor unit

| The unit may accumulate dust during extended periods of non-use, which will be emitted when the unit is turned on.
