OPERATING TIPS
Notice
Instructions relating to heating (*) are applicable only to "HEAT & COOL MODEL" (Reverse Cycle).
*● During use of the heating mode, the outdoor unit will
occasionally commence the defrost operation for brief
periods. During the defrosting operation, if the user sets
the indoor unit for heating again, the defrosting mode
will continue, and the heating operation will begin after
completion of defrosting, with the result that some time
may be required before warm air is emitted.

● If the air conditioner is operated under higher temperature conditions than those listed, the built-in protection circuit may
operate to prevent internal circuit damage. Also, during Cooling and Dry modes, if the unit is used under conditions of lower
temperatures than those listed above, the heat-exchanger may freeze, leading to water leakage and other damage.
● Do not use this unit for any purposes other than the Cooling, (*)Heating, Dehumidifying, and air-circulation of rooms in
ordinary dwellings.
