Installing the Refrigerant Pipe Work (Continued)
To Close the Valve Stem
1
Open the cap and turn the valve stem clockwise by using a
hexagonal wrench.
2
Tighten the valve stem until it reached the sealing edge.
Note
Do not apply excessive force to the valve stem
and always use special instruments. Otherwise,
the contact surface between valve stem and
sealing edge can be damaged and refrigerant
can leak through this damaged surface.
If refrigerant would leak, turn the valve stem
back by half and
tighten the valve stem again, then check the
leakage. If there is no leakage any more,
tighten the valve stem entirely.
3
Tighten the cap securely.
