Test run

 Before test run
• Before turning on the power supply, carry out the following procedure.
1) By using 500 V-megger, check that resistance of 1 MΩ or more exists between the terminal block L to N
and the grounding.
If resistance of less than 1 MΩ is detected, do not run the unit.
2) Check the valve of the outdoor unit being opened fully.
• To protect the compressor at activation time, leave power-ON for 12 hours or more before operating.
• Do not press the electromagnetic contactor to forcibly perform a test run. (This is very dangerous because the
protective device does not work.)
• Before starting a test run, set addresses by following the Installation Manual supplied with the outdoor unit.
 Execute a test run
• When a fan operation is to be performed for an individual indoor unit, turn off the power, short CN72 on the circuit
board, and then turn the power back on. (First set the operating mode to "fan," and then operate.) When the test
run has been performed using this method, do NOT forget to release the shorting of CN72 after the test run is
completed.
Operate the unit with the wired remote control as usual.
For the procedure of the operation, refer to the attached Owner's Manual to the outdoor unit.
A forced test run can be executed in the following procedure even if the operation stops by thermostat-OFF.
In order to prevent a serial operation, the forced test run is released after 60 minutes have passed and returns to
3
the usual operation.
.
CAUTION
Do not use the forced test run for cases other than the test run because it applies an excessive load to the devices.
