HOW TO HANDLE AN ANODE-CAP
1 Do not damage the surface of anode-caps with
sharp shaped objects.
2 Do not press the rubber too hard so as not to
damage the inside of anode-cap.
A metal fitting called the shatter-hook terminal is
built into the rubber.
3 Do not turn the foot of rubber over too hard.
The shatter-hook terminal will stick out or damage
the rubber.
