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 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 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 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 nearby 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.
Closing curtains during heating also helps keep the heat in
Doors and w indow s should be kept closed

Operation mode selection
Optimal operation
While two or more indoor units are simultaneously operating, make sure the modes do not conflict with each other. The heat mode claims precedence over all other modes. If the unit intially started to operate in HEAT mode, the other units can operate in HEAT mode only. For example: If the unit intially 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 diplay “–” (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) wil light up, or the operation indication light will flash rapidly, and the timer indication light will turn off ( for the floor and standing type).
M aintenance
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 dry 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 or a customer service centre if the unit requires servicing.
NOTE: Before you clean the air conditioner, be sure to switch off the unit and disconnect the power supply plug.
To achieve optimal performance, please note the following: · Adjust the direction of the air flow so that it is
notblowing 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 a 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 per formance may be reduced. · Do not operate unit with horizontal louvre in closed position.
Suggest ion: For units that feature an electric heater, w hen the outside ambient temperature is below 0°C (32°F), 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.
