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

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.
Doors and windows should be kept closed
