Section 7 Refrigeration System
7-58
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.
