OPERATING TIPS
Instructions relating to heating (*) are applicable only to “HEAT & COOL MODEL” (Reverse Cycle).
In Event of Power Interruption
AUTO Restart
● If a power failure occurs during TIMER operation, the timer
will be reset and the unit will begin (or stop) operation at
the new time setting. In the event that this kind of timer
fault occurs the TIMER Indicator Lamp (green) will flash
(see page. 4).
● Use of other electrical appliances (electric shaver, etc.) or
nearby use of a wireless radio transmitter may cause the
air conditioner to malfunction. In this event, temporarily
disconnect the power supply, reconnect it, and then use
the remote control unit to resume operation.
● The air conditioner power has been interrupted by a
power failure. The air conditioner will then restart auto-
matically in its previous mode when the power is restored.
● Operated by setting before the power failure.
● Acoustic Noise Information: The maximum sound pressure level is less than 70 dB (A) for both indoor unit and outdoor
unit. According to IEC 704-1 and ISO 3744.
● 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.
● When the outdoor temperature drops, the outdoor unit’s fans may switch to Low Speed.
● If the unit is used for long periods under high-humidity conditions, condensation may form on the surface of the indoor
unit, and drip onto the floor or other objects underneath. (About 80% or more)
