Section 6 Refrigeration System

Refrigerant Re-Use Policy

Manitowoc recognizes and supports the need

for proper handling, re-use, and disposal of,

CFC and HCFC refrigerants. Manitowoc

service procedures require recapturing

refrigerants, not venting them to the

atmosphere.

It is not necessary, in or out of warranty, to

reduce or compromise the quality and

reliability of your customers’ products to

achieve this.

Important

Manitowoc Ice, Inc assumes no responsibility

for use of contaminated refrigerant. Damage

resulting from the use of contaminated,

recovered, or recycled refrigerant is the sole

responsibility of the servicing company.

Manitowoc approves the use of:

1. New Refrigerant

• Must be of original nameplate type.

2. Reclaimed Refrigerant

• Must be of original nameplate type.

• Must meet ARI Standard 700 (latest

edition) specifications.

3. Recovered or Recycled Refrigerant

• Must be recovered or recycled in

accordance with current local, state

and federal laws.

• Must be recovered from and re-used in

the same Manitowoc product. Re-use

of recovered or recycled refrigerant

from other products is not approved.

• Recycling equipment must be certified

to ARI Standard 740 (latest edition)

and be maintained to consistently meet

this standard.

• 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” on page 6-15 to test for

contamination.

4. “Substitute” or “Alternative” Refrigerant

• Must use only Manitowoc-approved

alternative refrigerants.

• Must follow Manitowoc-published

conversion procedures.
