4. Recovered refrigerant must come from a

“contaminant-free” system. To decide whether the

system is contaminant free, consider:

• Type(s) of previous failure(s)

• Whether the system was cleaned, evacuated

and recharged properly following failure(s)

• Whether the system has been contaminated

by this failure

• Compressor motor burnouts and improper

past service prevent refrigerant re-use.

• Refer to “System Contamination Cleanup” to

test for contamination.

5. “Substitute” or “Alternative” Refrigerant

• Must use only Manitowoc-approved alternative

refrigerants.

• Must follow Manitowoc-published conversion

procedures.
