9. TEST RUN WHEN CONNECT TO RAC MULTI OUTDOOR
9-1. Precautions
● Request that the customer be present when the test run is performed.
At this time, explain the operation manual and have the customer perform the actual steps.
● Check that the 230 VAC power is not connected to the inter-unit control wiring connector
terminal.
* If 230 VAC is accidentally applied, the indoor unit control PCB fuse will blow in order to
protect the PCB.
In this case, make the wiring correctly.
Then disconnect the 2P connectors (OC) that are connected to the indoor unit control PCB,
and replace them with 2P connectors (EMG).
If operation is still not possible after changing the brown connectors, cut the jumper on the
indoor unit control PCB.
(Be sure to turn the power OFF before performing this work.)
