3.Connect the charging hose of the low-pressure side of manifold gauge to a gas service port as seen in the picture.

4.Open the valve of the low pressure side of manifold gauge counterclockwise.

5.Purge the air in the connected pipes using the vacuum pump for about 15 minutes.

Make sure that pressure gauge shows -0.1MPa(-76cmHg) after about 10 minutes.

This procedure is very important to avoid a gas leak.

Close the valve of the low pressure side of manifold gauge clockwise.

Turn off the vacuum pump.

Check for 2 minutes if there is any pressure change.

Remove the hose of the low pressure side of manifold gauge.

6.Set a valve cork of liquid and gas service port to the open position.

7.Mount the valve stem nuts and the service port cap to the valve, and tighten them at the torque of 183kgf•cm with a torque wrench.

8.Check for a gas leak paying particular attention to the 3-way valve’s stem nuts and to the service port cap (Refer to page 41).
