Operation Mechanism
Heating performance
z
Since this air conditioner utilizes outside air for heating,
its heating performance deteriorates as outside tempera-
ture decreases.
(Due to heat pump system)
→In that case, use another heating appliance.
Defrosting
z
This appliance may start defrosting operation to melt
frost formed in the outdoor unit.
Defrosting starts
: The indoor unit fan stops (or the
speed becomes extremely slow).
→“
” (STANDBY) appears.
Heating operation resumes after several
minutes
: The indoor unit fan remains stopped (or
it will run at a very slow speed) until the indoor heat
exchanger coil warms up sufciently.
→ “
” (STANDBY) is shown.
Defrosting is complete
: The indoor unit fan starts
operation.
→ “
” (STANDBY) disappears.
‘‘DRY’’ operation
z
Once the room temperature reaches the level that was
set, the outdoor unit repeats the cycle of turning on and
off automatically.
z
When the outdoor unit is turned off, the indoor unit fan
will stop, too.
(To prevent the humidity in the room from rising again)
z
When the room temperature is more likely to reach the
level that was set, the fan speed is set to ‘‘breeze’’ (light
wind) automatically.
Should the power failure occurs while the
unit is running
When the unit automatically resumes operation after
temporary power failure, it uses the same settings before
the power was cut off.
WARNING
z
For safety, be sure to turn the air conditioner off and disconnect
the power before cleaning. (Otherwise, electric shock or injury may
result because the fan is rotating at high speed.)
z
Do not pour water on the indoor unit. (This may damage the internal
components and cause an electric shock hazard.)
CAUTION
z
Never use solvents or harsh chemicals. Also, do not wipe plastic
parts using very hot water. (This may cause deformation or change
in colour.)
z
Some metal edges and ns are sharp. Be careful when you clean
those parts. (Injury may result.)
z
Use a rm stool or ladder when cleaning an indoor unit installed in
high locations.
