Panasonic S-36PU1E5A Service Manual page 318

1
Type U1, T2, F1, N1 and Y2 (for Link Wiring)
Caution
This unit may be used in a single-type refrigerant system where 1 outdoor unit is connected to 1 indoor unit,
and also in a system where 1 outdoor unit is connected to multiple indoor units (maximum 2 < Twin >).
This test run explanation describes primarily the procedure when using the wired remote controller.
If link wiring is used, set the outdoor unit system address to allow the combination of indoor and outdoor units to
be identified.
At the same time, indicate the indoor-outdoor unit combination number in a location where it can be checked easily
(near the indoor unit nameplates). (This number will be required for subsequent maintenance.)
Request that the customer be present when the test run is performed. At this time, explain the Operating Instructions
and have the customer perform the actual steps.
Be sure to pass the manuals and warranty certificate to the customer.
Check that the 220 – 240 V AC wiring is not connected to the inter-unit control wiring connector terminal.
If 220 – 240 V AC is accidentally applied, the indoor or outdoor unit control PCB fuse will blow in order to protect
the PCB. Correct the wiring connections, then disconnect the 2P connectors (indoor: blue, OC) (outdoor: blue,
serial 1) that are connected to the PCB, and replace them with 2P connectors (indoor: brown, EMG) (outdoor:
brown, serial 2).
If operation is still not possible after changing the brown connectors, try cutting the varistor (black).
(Be sure to turn the power OFF before performing this work.)
