8. When you have charged the system, close both manifold
handwheels. Let the compressor run and check the
manifold’s gauge pressure readings to be sure the
system is operating properly. If it is not, adjust the
system as necessary. To disconnect the manifold when
the system is operating correctly, see the steps below for
your specific manifold.
• For the 40134A manifold, first close the high side
coupler valve. Open the low side coupler valve. Then
disconnect the red high side hose from the A/C system.
After disconnecting, go to step 9.
• For all other manifolds, close both handwheels on the
manifold. Carefully remove the charging hoses from the
system. Charging is now complete.
9. Restart the A/C system, then open both manifold
handwheels. Refrigerant from both hoses will be drawn
quickly into the A/C system through the blue low side
hose.
10. When both gauges show the lowest operating pressure
recommended by the manufacturer, close the low side
valve and turn off the A/C system.
11. Close the low side coupler valve and disconnect the low
side hose from the A/C system.
