Scale accumulation in the bottom of the storage tank may be removed by turning off main power and draining the tank. Once all water is removed, the hand hole access can be removed. This will allow large accumulations of scale to be cleaned from the bottom of the tank.

NOTE: All gaskets on disassembled clean-out openings must be replaced with new gaskets on re-assembly.

Gaskets are available from your distributor.

Water scale accumulations on the immersion heating element reduce the ability of the elements to heat water and may cause noise to occur during operation. It is recommended that a heating element be removed at least once a year for examination. If it is scaled, all of the elements should be removed and cleaned. The element gasket must be replaced when the element is removed for cleaning.

Small accumulations of lime scale may be removed with a stiff bristle brush. Severe accumulations of lime scale should be removed by dissolving the accumulation in a commercial delimer. Do not use muratic or hydrochloric acid base deliming solutions to remove lime scale from the elements. Do not pour delimer into tank. Deliming solutions may damage the glass lined interior of the tank

DANGER:

Keep all delimers away from anode rods to prevent the formation of flammable and explosive gas.

1.Drain the heater following “SHUTDOWN PROCEDURE” instructions.

2.On some high kW input models it is necessary to remove a side panel to gain access to the exposed ends of the elements which are not accessible through the front element access door.

3.Disconnect the wires attached to the element terminals. Try not to disturb the wiring unnecessarily and reconnection will be easier.

4.Loosen the screw-in element flange with a socket and breaker bar. Do not use an impact gun (air or electric) to remove the element flanges from the tank. Mark the location of each element in the tank openings so they may be returned to their original position.

5.Remove the elements from the opening with a twisting, pulling action if the elements are scaled beyond the size of the tank flange openings. Brush loose scale from elements.

6.Place scaled ends of heating elements into a delimer solution and allow scale to dissolve. Do not permit delimer or water to contact heating element electrical terminals.

7.Flush clean ends of elements with water when deliming or cleaning is completed.

8.Clean remaining gasket recess on each screw-in element flange. Do not reuse element gaskets.

9.Install a new gasket on each element. Install element into the tank opening where it was originally installed. Tighten the flange with the socket and breaker bar used to remove the element.

10.Attach wires to element terminals from which they were removed.

11.Follow “FILLING THE WATER HEATER” instructions to restore hot water service. Check for water leaks around elements and proper operation when heater is filled.
