Pinch the charging pipe with pliers. Remove the service valve and solder the hole together.
Brush off all solderings in the system and check for possible leakage with an electronic leak detector. Check the pressure side when the compressor is in operation and the suction side when the system is pressure equalized.
Coat the area around the solderings with tectyl or paint for corrosion protection.
Test the unit. Check to ensure that the evaporator frost over as usual.
The refrigerant bag is dismounted from the vacuum pump outlet and the refrigerant is later emptied to a pressure vessel intended for used refrigerant. This is done using a special emptying unit - see section 2.1.2.
