9. When satisfied that the unit is operating correctly,
clamp the high-side process tube with the pinch-off
tool while the unit is still running.

allow the compressor to remove any refrigerant

corrected before proceeding.

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 adaptor and solder the process tube
closed.
