Refrigerant Charging; Table 3 - Refrigerant Charge - York YD A Operating & Maintenance

SECTION 6 – MAINTENANCE

REFRIGERANT CHARGING

To avoid the possibility of freezing liquid within the
evaporator tubes when charging an evacuated system,
only refrigerant vapor from the top of the cylinder
must be admitted to the system pressure until the sys-
tem pressure is raised above the point corresponding to
the freezing point of the evaporator liquid. For water,
the pressure corresponding to the freezing point is 8.54
PSIG (58.9 kPa) for R-134a (at sea level).

While charging, every precaution must be taken to pre-
vent moisture laden air from entering the system.
The charging connection should be purged each time
a full cylinder of refrigerant is connected or changed.
Refrigerant may be furnished in cylinders contain-
ing either 30, 50, 125 or 1750 lbs. (207, 345, 862, or
12,066 kg) of refrigerant.
