Operating temperature range
• The built-in protective device may prevent the unit
from operating when used out of this range.
• Condensation may form on the air outlet if the unit
operates continuously in the COOL or DRY mode
when humidity is over 80 percent.
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-ice
function 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 atmosphere and releases it into the room.
The outside 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 can 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
Take advantage of the timer off function
Disconnect the power supply when the unit is not
going to be used for an extended period of time
• The indoor unit still consumes a small amount of power
when it is not operating.
