4.3.2 Piping Preparation
All cut ends are to be round, burr free, and cleaned. Failure to follow this practice
increases the chances for refrigerant leakage.
First, wrap the rubber grommet with water saturated cloth, and then weld off the
cap closures from the gas and liquid pipes. Then weld the gas and liquid pipes with the
connecting pipes.
