Regulations on wire size differ from locality to locality. For field wiring requirements, please refer to your local electrical codes. Make sure that the installation fully complies with all local and national regulations.

(1)Remove access panel “C”. (Fig. 32)

(2)Connect the inter-unit wiring and power line according to the drawing on the panel side.

(3)Be sure to size each wire allowing approx. 10 cm longer than the required length for wiring. Store excess wiring inside the cabinet.

(4)When connections are completed, check that all connections are correct as shown in the wiring system diagram on panel side.

(5)Be sure to ground the unit according to your local codes.

6. Test Run

Performing a test run

Refer to the test run procedures in the indoor unit installation manual.

Perform the test run separately for each connected indoor unit. If 2 units are operated simultaneously, it is not possible to correctly check for errors in tubing and wiring.

If the room temperature is 15°C or below, it may not be possible to check for tubing errors with cooling operation. If this occurs, perform heating operation for each unit individually, and check that warm air is dis- charged from each unit. If there is cold air mixed in with the warm air, check the tubing connections again.

Checking tubing and wiring

Perform the test run and check that operation is normal. If there is an error in tubing or wiring, the refrigerant may flow to indoor unit B when indoor unit A is operated (for example).

CAUTION

Stop operation immediately if there is an error in tub- ing or wiring. Turn the power (breaker) OFF, and check whether the inter-unit cables are connected incorrectly, or whether the narrow tubes A and B are connected in reverse. Correct the connections.

If there is an error in tubing, pump-down must be performed. Be sure to perform pump-down. After making corrections, again purge the air from the tubes.
