OPERATING TIPS
AUTO Restart
In Event of Power Interruption
●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.
●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 will flash (see Page. 3).
●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 Plug, reconnect it, and then use the Remote Control Unit to resume operation.

Simultaneous Use of Multiple Units
●When using a
●Seasonal and outdoor temperature conditions, the struc- ture of the rooms and the number of persons present may also result in differences of operating efficiency. We recommend that you try various operating patterns in order to confirm the level of heating and cooling out- put provided by your units, and use the units in the way that best matches your family’s lifestyle.
●If you discover that one or more units delivers a low level of cooling or heating during simultaneous opera- tion, we recommend that you stop simultaneous opera- tion of the multiple units.
●Operation cannot be done in the following different op- erating modes.
If the indoor unit is instructed to do an operating mode that it cannot perform, the OPERATION indicator lamp (red) on the indoor unit will flash (1 second on, 1 sec- ond off) and the unit will go into the standby mode.
Heating (COIL DRY) mode and cooling mode (or dry mode)
Heating (COIL DRY) mode and fan mode
●Operation can be done in the following different operat- ing modes.
Cooling mode and dry mode
Cooling mode and fan mode
Dry mode and fan mode
Heating mode and COIL DRY mode
●The operating mode (heating (COIL DRY) mode or cool- ing (dry) mode) of the outdoor unit will be determined by the operating mode of the indoor unit that was oper- ated first. If the indoor unit was started in fan mode, the operating mode of the outdoor unit will not be deter- mined.
For example, if indoor unit (A) was started in fan mode and then indoor unit (B) was then operated in heating mode, indoor unit (A) would temporarily start opera- tion in fan mode but when indoor unit (B) started oper- ating in heating mode, the OPERATION indicator lamp (red) for indoor unit (A) would begin to flash (1 second on, 1 second off) and it would go into standby mode. Indoor unit (B) would continue to operate in heating mode.
Notice
●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.
●During use of the heating mode, the top of the indoor unit may become warm, but this is due to the fact that coolant is circulated through the indoor unit even when it is stopped; it is not a malfunction.
