6.3 PRECAUTIONS DURING BRAZING SERVICE VALVE 10. Replace cap on service ports. Do not remove the flare caps from the service ports except when necessary for servicing the system. Precautions should be taken to prevent heat damage to service valve by wrapping a wet rag around it as shown in Fig.
Procedure of using stop valve Open the spool until it touches the stop block. Do not attempt to open further. Use a spanner or a similar tool to tighten the bonnet. The bonnet tightening torque is shown in aboveTable “Tightening torque”. Fig.6-3 Use refrigerant tank to expel air (see Fig.6-2 and Fig.6-3 ) Upon completion of installation, open all valves before trial run.
