● Before starting the test run, measure the voltage at the primary side of the safety breaker.
● Check that all liquid and gas stop 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
PC-board. However, the wiring error check switch will not
function for 3 minutes after the safety breaker is turned on, or
depending on the outside air conditions (See Note 2.).
Approximately 15 ~ 20 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 manual.
If self-correction is not possible, check the indoor unit wiring and
piping in the usual manner.
