SERVICE - Continued
Brazing
Braze joints within the air conditioner as follows:
1.
Position the component to be installed.
2.
To prepare a joint on a valve for brazing, disassemble the valve to the extent possible. Then wrap all but the joint
with a wet rag to act as a heat sink.
3.
Protect insulation, wiring harnesses, and surrounding components with appropriate shields.
4.
Be sure the work area is well ventilated and that dry nitrogen is flowing through the refrigeration system at a rate of
less than 1-2 cfm (0.028-0.057 m3/ minute).
5.
Apply sufficient heat uniformly around the joint to quickly raise it to a temperature that will melt the filler alloy.
Remove heat as soon as brazing is completed.
