3 Open the valve of the low pressure side of manifold
gauge counter clockwise.
4 Purge the air from the system using vacuum pump for
about 30 minutes.
• Close the valve of the low pressure side of manifold
gauge clockwise.
• Make sure that pressure gauge show -14.5 psi
(-0.1 MPa). after about 30 minutes. This procedure
is very important in order to avoid gas leak.
• Turn off the vacuum pump.
• Remove the hose of the low pressure side of
manifold gauge.
5 Set spindle of both liquid side and gas side of stop
valve to the open position.
6 Mount the valve stem nuts and the service port cap to
