1. Turn up one side of the rubber cap in

HOW TO HANDLE AN ANODE-CAP
1. Do not use sharp objects which may cause damage to the
surface of the anode-cap.
2. Do not squeeze the rubber covering too hard to avoid damaging
the anode-cap. A material fitting called a shatter-hook terminal
is built into the rubber.
3. Do not force turn the foot of the rubber cover. This may cause
the shatter-hook terminal to protrude and damage the rubber.
