Indoor Units (Type E2, E1) (for Link Wiring)
2-16. Caution
This unit may be used in a single-type refrigerant system where 1 outdoor unit is connected to 1 indoor unit.
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. Refer to 2-21-2, 3, 4.)
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.
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.)
