15.2.1 Using the stop valve and service port
To handle the stop valve
Take the following guidelines into account:
▪ The gas and liquid stop valves are factory closed.
▪ Make sure to keep all stop valves open during operation.
▪ Do NOT apply excessive force to the stop valve. Doing so may
break the valve body.
To open the stop valve
1 Remove the dust cap.
2 Insert a hexagon wrench into the stop valve.
3 FULLY turn the stop valve counterclockwise and tighten until
the correct tightening torque value is achieved (see "Tightening
torques"[428]).
NOTICE
Stop valves need to be opened on torque specified in this
manual. It is not allowed to turn valve "a quarter turn" back
when opening it.
4 Install the dust cap.
Result: The valve is now open.
NOTICE
Reinstall dust cap to prevent aging of O-ring and risk of
leakage.
