Frigomatic Milano Manual v1 PAGE 8
GROUNDING AND CLEANING THE KEEL COOLER:
Provision is provided for a grounding/bonding wire to be attached. It is very important that
the Keel Cooler is electrically connected to the battery negative, with no switch in the
circuit between the Keel Cooler connection and the battery negative.
If the Keel Cooler being installed is the type without zincs, it must also be connected to the
vessel’s bonding system and a sacrificial zinc anode. This is an important safety
precaution and a connection must be made to the battery negative whether the keel cooler
has zincs or not.
The keel Cooler should not be painted and must be inspected periodically for corrosion.
Clean occasionally with a brush, never with a metal scraper.
For details on the recommended grounding please see the Frigoboat Correct
Bonding document
