Test run
Before test run
• Before turning on the power supply, carry out the following procedure.
1. By using an insulation tester (500 VMΩ), check that resistance of 1 MΩ or more exists between the terminal block L
to N and the earth (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.)
CAUTION
Be careful of the long - time forced operation because it may result in break.
Perform the test run check with cooling/heating, and check that it is satisfactory with the whole system.
