Copeland Scroll Compressor ZP72KCE

Follow the lockout/tag out procedure and national regulations before maintenance.

Ensure compressor is used with a grounded system.

Use screwed electrical connections in all applications.

Ensure electrical connections are made by qualified personnel.

Remove all refrigerant before opening the system.

Avoid working with an unshielded flame in a refrigerant-charged system.

Compressor Operation Precautions

Define the system high-side PS ≤ compressor high-side PS.

Isolate the high- and low-pressure sections of the system by closing valves, solenoid valves, expansion valves or by other means.

Use the internal check valve of the compressor on the discharge side or add an external check valve. To protect the compressor internal check valve, observe a maximum pressure delta of ≤ 40 bar between the high-pressure side and the low-pressure side.

Activate the check valve with a fast pressure increase. Once the check valve is activated, the pressure increase can be slowed down.

Apply the system test pressure of 1.1 x system high-side PS for a short time.

Ensure the pressure inside the compressor does not exceed the maximum PS value, which corresponds to the compressor low-pressure PS.

Define the system low-side PS ≤ compressor low-side PS.
