4. To install the replacement drier remove
factory seals and solder the refrigerant lines and
the capillary tube taking precautions to NOT
OVERHEAT the drier body.
5. Thoroughly evacuate the system to remove
moisture and non condensable after drier
replacement.
6. Charge the system with proper refrigerant
by weight (see data plate of machine) and check
for leaks.
7. Replace panels previously removed.
M. REPLACEMENT OF THE FREEZING
CYLINDER
1. Follow the steps at item H to remove the ice
spout.
