NOTE
• Do not apply excessive force to the stop valve and
always use special instruments. Otherwise, the
stopping box can be damaged and the back sheet can
leaks.

half, tighten the stopping box, then check the leakage
again. If there is no leakage any more, tighten the axis
entirely.

2 Turn the stop valve clockwise by using a hexagonal
wrench.
3 Tighten the axis until the valve reached the sealing
point.

hose, too.
• Check the leakage of refrigerant gas after tightening the
cap.
• Must use a spanner and wrench when you open/tighten
the stop valve.
