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 for used refrigerant. This hose is to have a closing valve when connected to the emptying unit.
When the required bag(s) haslhave been emptied the pressure sensitive switch will stop the emptying unit. In case air should 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.)
Make sure to observe all existing rules concerning the recovery of used refrigerant and the contents allowed for the vessel - approx. 75% of the weight stated on the vessel.
Note the specifications stated on the refrigerant bags - e.g.:
Refrigerant bag for R12 | or R134a |
Contents max. 250 g | 200 g |
Temperature max. +60C | +60C |
