Section 7 Refrigeration System
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.
