2.1.2. Emptying used Refrigerant to Pressure Vessel
from Refrigerant Bag
Connect the suction valve on the emptying unit with hose to the
outlet valve on the emptying rack for refrigerant bags. Open the
main valve and the valve for the bags to be emptied.
Connect the pressure valve on the emptying unit to the vessel

connected to the emptying unit.

enter the vessel causing the pressure to rise the pressure sen-
sitive switch will also stop the emptying unit and the pressure
vessel should be bled. (Can be bled by means of the bleeder
valve on the emptying unit.)

of used refrigerant and the contents allowed for the vessel -
