DURING
THE
AIR CONDITIONER
OPERATION
l
A built-in
protective
device
may prevent
the unit from operating
when the
ambient temperature
is extremely
high or low.
l
Dew may form on the air outlet when the unit operates continuously
in the COOL
or DRY mode when the humidity is over 80%.
3-MINUTE
PROTECTION
After the unit has been turned off, a protective
mechanism
prevents
it from being
turned on again for three minutes.
FAN SPEED
l
When the fan speed is set to AUTO in the COOL mode, the fan speed automati-
cally decreases
as the room temperature
nears the thermostat
setting.
l
When the room temperature
reaches the thermostat
setting in the HEAT mode,
the compressor
stops and the indoor fan changes to the SOFT setting or stops.
l
In the DRY mode, the fan speed is controlled
automatically.
PREHEATING
FUNCTION
In the HEAT operation, the indoor fan may not start for 2-5 minutes after the unit is
turned on to prevent the air from circulating
before the unit is sufficiently
warmed
UP*
DE-ICING FUNCTION
l
When ice forms on the heat exchanger
in the outdoor
unit during the HEAT
operation,
an automatic de-icer provides heat for about 2-10 minutes to remove
the ice. During de-icing, the inside and outside fans stop operating.
l
After de-icing
is completed,
the unit automatically
resumes
operation
in the
HEAT mode.
HEATING EFFICIENCY
l
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.
l
If low outside
temperatures
adversely
affect the heating
efficiency,
use an
additional
heater.
l
It takes time to warm up and heat the entire room because this unit employs a
forced air circulation
design. To warm up the room in advance,
use the timer in
the HEAT operation.
