5-18. CHARGING THE SYSTEM (cont.).
CAUTION
Do not attempt to charge liquid refrigerant into the suction line. The compressor would be
damaged.
NOTE
Two kinds of refrigerant cylinders are in general use. One is equipped with a single shutoff
valve, and must be inverted when charging liquid refrigerant. The other is equipped with a
vapor valve and a liquid valve, which makes it possible to charge with either liquid or
vapor when the cylinder is upright.
Whenever available, use recycled refrigerant for charging the refrigeration system.
