TEST RUN

Preparation
 Before turning on the power supply, carry out the following procedure.
1) Using 500V-Megger, check that the resistance of 1MΩ or more exists between the terminal block of the power supply
and the earth (grounding).
If resistance of less than 1MΩ 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.
 Never press the electromagnetic contactor to forcibly perform the test run. (This is very dangerous because the protective
device does not work).
 Before starting a test run, be sure to set addresses following the installation manual supplied with the outdoor unit.

operation stops by thermo-OFF.
In order to prevent a serial operation, the forced test run is released after 60 minutes have passed and returns to the usual
