■
Do not remove the caps from the lines or system connection
points until connections are ready to be completed.
Prepare Tubing
■
All cut ends are to be round, burr free, and cleaned. Failure to
follow this practice increases the chances for refrigerant
leaks.
■
The suction line is spun closed and requires a pipe cutter to
remove the closed end.
Post Brazing
■
Cool all welded joints with water or a wet rag.
