ADDITIONAL NOTES ON OPERATION
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 continu-
ously in the COOL or
DRY mode when humid-
ity 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-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.
