High Pressure Cutout Switch Installation

Install the high pressure cutout switch by performing the following steps:

1. Apply Locktite sealant to the threads of the switch.

2. Install switch in compressor flange.

3. Pressurize the compressor with refrigerant and check for leaks.

4. Evacuate the compressor (see “Evacuation and Cleanup of the Refrigeration System”).

5. Route wires into the control box and connect to proper terminals.

6. Back seat the discharge service valve by turning the valve fully counter-clockwise.

7. Back seat the suction service valve by turning the valve fully counter-clockwise.

8. Turn the digital service valve one quarter turn to the left.

9. Perform a controller pretrip test to verify system operation.
