process tube closed.
13. Clamp low-side process tube with pinchoff tool while
unit is running. Remove low-side process tube
adaptor and solder process tube closed.

1. With refrigerator turned OFF, leak test all low-side
system components.
2. Turn unit ON and run until condenser is warm. Leak
test high-side system components.
