ADDITIONAL NOTES ON
OPERATION
OPERATING TEMPERATURE RANGE
COOLING
HEATING
• 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
2
for two to fi ve 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.
1
• After de-icing is completed, the unit automatically
resumes operation in the HEAT mode.
3
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 effi ciency.
• If the heating effi ciency 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.
