attached to the machine as
explained in the Setup section.
2) Fill the oil inject bottle with
new oil as explained in the
Setup section.
The charge process is
automatically interrupted and
the machine operates in a

Once tank pressure is sufficient,
the machine automatically
completes the charge.
Press ESC. Refer to Recover
section and recover refrigerant
before proceeding.
Refer to Manually Fill the
