Copeland Scroll Compressor ZP61K5E

Follow the lockout/tag out procedure and national regulations

Ensure compressor is connected to a grounded system

Use screwed electrical connections in all applications

Verify 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

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.

Ensure maximum pressure delta of ≤ 40 bar between the high-pressure side and the low-pressure side to protect the compressor internal check valve.

Activate the check valve with a fast pressure increase.

Once the check valve is activated, slow down the pressure increase.

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, corresponding to the compressor low-pressure PS.

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

Ensure personal safety requirements are considered

Refer to test pressures prior to test

Use only dry inert gases for leak testing

Ensure no other industrial gases are used

Verify the following conditions before starting the test

Perform leak-pressure test after opening or modifying connections

Follow lockout/tag out procedure and national regulations before maintenance

Use compressor with grounded system only

Ensure electrical connections are made by qualified personnel

Remove all refrigerant before opening the system

Remove contaminated oil with the compressor in case of motor burnout

Install suction and liquid line filter-dryers

Was the suction accumulator replaced?
