Test Run
Precautions
(1) Change the indoor control unit switch from “ON” → “TEST”.
(The outdoor unit will not operate for 3 minutes after the
power is turned ON and after operation is stopped.)
(2) All the indicator lamps blink while the test run is in progress.
(3) Temperature control is not possible during the test run.
(4) If correct operation is not possible, the trouble will be
indicated by the indicator lamps.
Refer to “Table of Self-Diagnostic Functions and Corrections
(Type K1)” and correct the problem.
(5) After the test is completed, change the control unit switch
from “TEST” → “ON”.
Confirm that the indicator lamps have stopped blinking. (A function is included which cancels the test run after
a 60-minute timer has elapsed, in order to prevent continuous test run operation.)
This mode places a large load on the devices. Use it only for performing test runs.
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.
A test run is not possible if the power is turned ON with the switch in the TEST position.
After the power has been turned ON, change the switch once to ON or OFF, then switch it back to the TEST
position.

TEST
* If 220 – 240 V AC is accidentally applied, the indoor or outdoor unit control PCB fuse (0.5 A for both indoor
and outdoor units) will blow in order to protect the PCB.
Correct the wiring connections, then disconnect the 2P connectors (indoor: blue) (outdoor: blue, serial 1)
that are connected to the PCB, and replace them with 2P connectors (indoor: brown) (outdoor: brown, serial 2).
If operation is still not possible after changing the brown connectors, cut off the jumper (outdoor unit : JP007)
or the varistor (indoor unit) on the PCB. (Be sure to turn the power OFF before performing this work.)
