WHEN POWER FAILURE OCCURS
This air conditioner has a memory function to store settings when a power failure occurs.
After power recovery, the unit will automatically re-start in the same settings which were active before
the power failure, except for timer settings.
If the timers were set before a power failure, they will need to be re-set after power recovery.
PREHEATING FUNCTION
In the HEAT operation, the indoor fan may not start for two to five minutes after the unit is turned on
to prevent cold air from blowing out of the unit.
DE-ICING FUNCTION
• When ice forms on the heat exchanger in the outdoor unit during the HEAT operation, an automatic
de-icer provides heat for about 5 to 10 minutes to remove the ice. During de-icing, the inside and
outside fans stop operating.
• After de-icing is completed, the unit automatically resumes operation in the HEAT mode.
HEATING EFFICIENCY
• The unit employs a heat pump that draws heat from the outside air and releases it into the room.
The outside air temperature therefore greatly affects the heating efficiency.
• If the heating efficiency is reduced due to low outside temperatures, use an additional heater.
• It takes time to warm up and heat the entire room because of the forced air circulation system.

TIPS ON SAVING ENERGY

Below are some simple ways to save energy when you use your air conditioner.
SET THE CORRECT TEMPERATURE
• Setting the thermostat 1°C higher than the desired temperature in the COOL mode and 2°C lower
in the HEAT mode will save approximately 10 percent in power consumption.
• Setting the temperature lower than necessary during cooling operation will result in increased
power consumption.
BLOCK DIRECT SUNLIGHT AND PREVENT DRAFTS
• Blocking direct sunlight during cooling operation will reduce power consumption.
• Close the windows and doors during cooling and heating operations.
SET PROPER AIR FLOW DIRECTION TO OBTAIN THE BEST AIR
CIRCULATION
KEEP FILTER CLEAN TO ENSURE THE MOST EFFICIENT OPERATION
MAKE MOST OF THE TIMER OFF FUNCTION
DISCONNECT THE POWER CORD WHEN THE UNIT IS NOT USED FOR AN
EXTENDED PERIOD OF TIME
• The indoor unit still consumes a small amount of power when it is not operating.
