Correct the error.

• After completing installation and the wiring and piping of the indoor and outdoor units, check for refrigerant leakage, looseness in the power supply or control wiring, wrong polarity, and no disconnection of one phase in the supply.

• To avoid damage to the compressor, make certain that all three phases of the power supply voltage are in the proper phase sequence.

• If connected in the reverse phase sequence, the indoor unit will not be able t o provide sufficient cooling air. The fan on the outdoor unit that is connected in the reverse phase sequence will tarn in the wrong direction

and makes the compressor rattle.

• If the outdoor unit is connected to the power supply voltage in the wrong phase sequence, P8 error occurs, or the built-in thermostat triggers the compressor to stop and results in P8 error. Once the built-in thermostat is triggered, it will take a long time until it returns to its pre-set temperature. Until then, the compressor cannot be started, even after the phase sequence is corrected.

• Use a 500-volt megohmmeter to check that the resistance between the power supply terminals and ground is

at least 1.0M".

• Do not carry out this test on the control wiring (low voltage circuit) terminals.

Warning: Do not use the air conditioner if the insulation resistance is less than 1.0M".

11-7. TIMER OPERATION

● Timer operation can be performed by setting the wired timer. Start and stop times can be set in 10-minute increments within a 24-hour period.

● When used in combination with the central control remote controller of the M-NET control system for the outdoor unit, one program timer can be used for individual timer settings for each group of the central control system. (Each timer setting can be stored in data memory so timer settings for up to 50 groups can be set individually.)

✻ Please refer to the MELANS catalog or technical information for details about the central control remote controller.

11-5. POWER OUTAGE AUTOMATIC RECOVERY OPERATION

• Whenever a power outage or switching of the power supply causes the power supply of an operating air conditioner to go

from OFF to ON, this function will automatically restore the operation of the air conditioner to its previous operating mode.

w If the power is turned from OFF to ON when the air conditioner is not in operation, the air conditioner will not automatically

be turned on. However, the timer operation will be cancelled if the air conditioner is in timer operation (including when the unit is waiting for its start time). Setting for timer operation must be performed once again.

• If there is a momentary power outage of less than one second while the air conditioner is in operation, there may not be a

clear determination of whether or not there was a power failure. When it has been determined that there has been a power failure, recovery will take approximately four minutes after the power is restored. Please wait. (Once "PLEASE WAIT" has appeared on the display, a protection system will operate to prevent the unit from restarting for three minutes.)

When it has been determined that there has been no power failure, operation will continue as is.

• Settings can be made by function selections from the remote controller.

• When there is group control, selection of all refrigerants is required.

11-6. INDIVIDUAL CONTROL OPERATION FROM A SEPARATE ROOM

• By simply centralizing the remote controllers installed in each room in a separate control room, individual control or central-

ized monitoring of the air conditioners in each room can be attained.

• Air conditioner control can be performed up to a total of 500 meters away by connecting the indoor units and remote con-

trollers with 0.3 to 1.25 mm

2-core cable.

• If a remote controller is installed in a room and control room, refer to the section on operating with two remote controllers.
