❚ Safety precautions
• Do not touch the aluminum fi ns on the
air heat exchanger.
It may result in injury.
• Do not place household electrical
appliances or household items under
neath the indoor or outdoor units.
Condensation falling from the unit may
stain objects and cause accidents or
electrical shock.
• Do not operate the system without
the air fi lter.
It can cause malfunction of the system
due to clogging of the heat exchanger.
• If you operate the system together
with a combustion appliance, you
must regularly ventilate the indoor
air.
Insuffi cient ventilation may cause acci-
dents due to oxygen defi ciency.
• Stand fi rmly on a stepladder or other
stable object when removing the inlet
panel and fi lters.
Failure to observe this may result in
injury through insecure objects toppling
over.
• When you clean the system, stop the
unit and turn off the power source.
Never open the panel while the internal
fan is rotating.
• Do not place objects near the out-
door unit or allow leaves to gather

If there are objects or leaves around the
outdoor unit, small animals may enter
unit and contact electrical parts and may
cause a break-down, smoke or fi re.

immediately after stopping the
operation.
Wait at least 5 minutes, otherwise there
