CCB COVER REMOVAL AND REPLACEMENT
The cover on the CCB enclosure must be removed for various service procedures outlined in this Service Handbook. Refer to the
instructions below when removing and replacing the CCB cover.
Wiring to and from the CCB and other water heater components enters the CCB enclosure on the bottom.
Removing the enclosure cover is a simple procedure. Care must be taken when replacing the CCB cover to ensure the wiring is routed
properly and the cover is replaced correctly. Follow the procedures below to ensure the wiring is not pinched or damaged and no
connectors are accidentally unplugged.
COVER REMOVAL PROCEDURE:
1. Ensure power to the water heater is turned off.
2. Remove the water heater’s top cover, UIM and the bottom plastic cover.
3. Remove the temperature probe connectors.
4. Unlock clips on both sides and remove the cover.
COVER REPLACEMENT PROCEDURE:
1. Follow Cover Removal Procedure in reverse order to replace cover.
Service Notes:
If any operational problems, fault conditions or Control System lock outs occur after the CCB enclosure cover has been removed and
replaced, remove the cover again to ensure none of the wiring connectors are unplugged and/or any of the wiring has been pinched,
cut or damaged. Unlike previous water heaters in this product line, the individual control boards inside the plastic enclosure are
serviceable parts. See the Parts List that was shipped with the water heater for the appropriate part numbers for each component.
