Notes:
• The unit must have at least 10 lbs. of refrigerant
available in the ISV (as indicated on the display)
for charging.
• If the ush process is interrupted by an
accidental power-down or other fault, use the
Recover mode to remove the refrigerant from
the vehicle.

Note: During this procedure, up to 12 lbs. of
refrigerant is charged into the vehicle A/C
system. If the ushing cycle is stopped before it is
complete and the external source valve is open,
the unit automatically adds refrigerant to the ISV,
and there will be no room to recover the refrigerant
used for ushing.
