Test Run and Final Check
• Before starting the test run, measure the voltage at the primary side of the safety breaker. Check that it is 220-240V.
• Check that all liquid and gas shut-off valves are fully open.
• Check that piping and wiring all match. The wiring error check can be conveniently used for underground wiring and other wiring
that cannot be directly checked.

Wiring error check
• This product is capable of automatic correction of wiring error.
• Press the "wiring error check switch" on the outdoor unit service monitor
print board. However, the wiring error check switch will not function for
one minute after the safety breaker is turned on, or depending on the
outside air conditions (See NOTE 2.). Approximately 10–15 minutes
after the switch is pressed, the errors in the connection wiring will be
corrected.
The service monitor LEDs indicate whether or not correction is
possible, as shown in the table below. For details about how to read the
LED display, refer to the service guide.
If self-correction is not possible, check the indoor unit wiring and piping
in the usual manner.
