Check For Refrigerant Leaks; How To Use The Tap Valve - SSANGYONG 2004 Rexton 2.7XDi Workshop Manual

5. Operate the vacuum pump and open the high and low
pressure valves.
6. Check whether the pointer in the low pressure gauge
indicates below pressure of -0.96 kg/cm
is not negative pressure, there may be a pressure leak
in the charging valve. In this case, perform the leak test.
7. Operate the vacuum pump again.
8. Maintain the pointers in both manifold gauges at -0.96
2
kg/cm .
9. Maintain the pointer in the low pressure gauge at -0.96
kg/cm 2 for 15 minutes.
10. After 15 minutes, close both manifold pressure valves
and stop the vacuum pump operation. Disconnect the
hose from the vacuum pump. This is stand-by condition
for charging.

Check for Refrigerant Leaks

1. Connect the center hose of the gauge to the refrigerant
tank.
2. Open the high pressure valve of the gauge to charge with
refrigerant gas.
3. Charge until the low pressure gauge reads 1.0 kg/cm
and close the valve.
4. Using a gas leak detector, check the system for leaks.
5. If any leak is found, replace O-ring or repair the faulty
connection.

How to Use the Tap Valve

1. Rotate the handle counterclockwise fully before
connecting the valve to the refrigerant tank.
2. Rotate the disk counterclockwise fully.
3. Connect the center hose to the valve fitting and then rotate
the disk clockwise fully by hand.
4. Rotate the handle clockwise to drill the sealed hole.
5. Remove the hose nut securing the center fitting of the
manifold gauge and then tighten the nut again in a few
seconds.
