System Contamination Clean-Up

General

This section describes the basic requirements for

restoring contaminated systems to reliable service.

DETERMINING SEVERITY OF CONTAMINATION

System contamination is generally caused by either

moisture or residue from compressor burnout entering

the refrigeration system.

Inspection of the refrigerant usually provides the first

indication of system contamination. Obvious moisture

or an acrid odor in the refrigerant indicates

contamination.

If either condition is found, or if contamination is

suspected, use a Total Test Kit from Totaline or a

similar diagnostic tool. These devices sample

refrigerant, eliminating the need to take an oil sample.

Follow the manufacturer’s directions.

If a refrigerant test kit indicates harmful levels of

contamination, or if a test kit is not available, inspect

the compressor oil.

1. Remove the refrigerant charge from the ice

machine.

2. Remove the compressor from the system.

3. Check the odor and appearance of the oil.

4. Inspect open suction and discharge lines at the

compressor for burnout deposits.

5. If no signs of contamination are present, perform

an acid oil test.

Check the chart on the next page to determine the

type of cleanup required.
