Flushing af t er c hanging t ype of oil
m
When servicing a vehicle, the type of oil in the vehicle's
A/C system should be noted to prevent a cross-contam-
ination inside the ACX1180. If a PAG system is serviced
and another vehicle with a POE system is to be serviced
next, a flush routine must be performed to prevent a
cross-contamination of the oils.
m
If the ACX1180 is not flushed, the internal hydraulic
system and the vehicle air conditioning system could be
damaged as a result of cross-contamination. MAHLE
cannot accept liability for any such damage.
1. Use and to scroll to High Volt age Oil Flush and
press YES.
2. Follow the menu prompting.
