the nut of refrigerant charging mouth.
5. Use inner hexagon spanner to twist off the liquid valve
body and at the same time use screwdriver to open
the valve core of the liquid valve. Now gas shall flow
out.
6. After gas continues flowing out for about 15 second
and refrigerant gas begins to flow out, close the valve
core and tighten the nut of refrigerant charge mouth.
7. Completely open the valve body of the liquid valve
and the gas valve. (See Fig 13)
8. Turn and tighten the valve cap, then use soap water
or a leak detector to check if there is gas leakage at
