ANODE

Inspect the anode. If it is worn out, replace it with a
new one. If scaling of the surface is evident, remove
the anode and clean it with a wire brush, and
remove all trace of oil or grease. After cleaning, pol-
ish the contact surfaces of the anode mount, and
re-install.
cC
Never paint the anode. To ensure good electrical
contact, keep the anode contact surface clean
of oil or grease.
