Maintenance: Freshwater system
Charge air cooler. Check the drain hole
Condensation can form in the charge air cooler during
operation. The condensation can be drained from a
nipple (1) on the bottom of the charge air cooler.
Make sure the nipple is not blocked.
IMPORTANT ! If considerable amounts of water
run out of the drain hole, the insert must be re-
moved and test pressurized. This must be done
by an authorised workshop.
