It is recommended that a heating element be removed periodically
for examination. If it is scaled, all of the elements should be removed
and cleaned. If the tank bottom has an accumulation of sediment it
should be cleaned.

delimer. Do not use muriatic or hydrochloric acid base
deliming solutions to remove lime scale from the elements.
THE PROCESS FOR LIME SCALE REMOVAL IS AS FOLLOWS:
1. Turn off electrical disconnect switch.

3. Open front panel.
4. Disconnect the element wiring. Try not to disturb the wiring
unnecessarily and reconnection will be easier.
5. Unscrew each element.
6. Remove the elements and gaskets from the openings.
