10. Slowly open the high-side manifold gauge valve to
allow the compressor to remove any refrigerant
trapped in the high-side hose and the process
fitting.
11. Close both of the manifold gauge valves. If the
high-side gauge reading rises, the pinch-off must be
corrected before proceeding.
12. Remove the high-side process tube adapter and
solder the process tube closed.
13. Clamp the low-side process tube with the pinch-off
tool while the unit is running. Remove the low-side
process tube adapter and solder the process tube
closed.
14. Check the process tubes for refrigerant leaks.
Final Leak Test
1. With the refrigerator turned OFF leak test all
low-side system components.
2. Turn the unit ON and run until the condenser is
warm. Leak test the high-side system components.
