Part 3 Test Run

1. Checkbefore Test Run

1

Check to see whether there is any refrigerant leakage, and check whether the power or transmission

cable is connected properly.

 

2

3

Check whether the liquid pipe and gas pipe valves are fully opened.

NOTE: Be sure to tighten caps.

Confirm that 500 V meter shows 2.0 MΩ or more between power supply terminal block and ground. Do not operate when there is of 2.0 MΩ or less.

NOTE: Never carry out mega ohm check over terminal control board.

Otherwise the control board may break.

Immediately after mounting the unit or after leaving it turned off for an extended length of time, the resistance of the insulation between the power supply terminal board and the ground may decrease to approx. 2.0 MΩ as a result of refrigerant accumulation in the internal compressor.

If the insulation resistance is less than 2.0 MΩ, turn on the main power supply.
