Section 7 Refrigeration System
Part No. 80-1100-3 7-61
7. Is other special equipment required to service HFC
refrigerants?
No. Standard refrigeration equipment such as
gauges, hoses, recovery systems, vacuum pumps,
etc., are generally compatible with HFC refrigerants.
Consult your equipment manufacturer for specific
recommendations for converting existing equipment
to HFC usage. Once designated (and calibrated, if
needed) for HFC use, this equipment should be
used specifically with HFC refrigerants only.
8. Do I have to recover HFC refrigerants?
Yes. Like other refrigerants, government regulations
require recovering HFC refrigerants.
9. Will R-404A or R-134A separate if there is a leak in
the system?
No. Like R-502, the degree of separation is too small
to detect.
10. How do I charge a system with HFC refrigerant?
The same as R-502. Manitowoc recommends
charging only liquid refrigerant into the high side of
the system.
