HOW TO HANDLE AN ANODE CAP

1.Do not use sharp objects which may cause damage to the surface of the anode cap.

2.To avoid damaging the anode cap, do not squeeze the rubber covering too hard. 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.

When one side of the rubber cap separates from the anode button, the anode cap can be removed by turning the rubber cap and pulling it in the direction of arrow c .
