Energy Saving Tips

• 

DO NOT 

set the unit to excessive temperature levels.

 

• 

While cooling, close the curtains in order to avoid direct sunlight. 

• 

Doors and windows should be kept closed so as to keep cool or warm air in the room. 

• 

DO NOT 

place objects near the air inlet or outlet of the unit. 

 

• 

Set a timer and use the built-in SLEEP/ECONOMY mode if applicable.

• 

If you do not 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 toward people, animals, or plants.

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 shifts 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 during 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 wireless devices 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.

Closing curtains during heating also
              helps to keep the heat in  

Doors and windows should be kept 
          closed as much as possible  

Inverter models will adjust their refrigeration
capacities automatically based on actual room
loads. Fan will keep running during operation.
