LEVEL CONTROL BOARD REPLACEMENT:
Disconnect electrical power to the BE unit before replacing
the Level Control Board.
When replacing a Level Control Board take care to install the proper wires onto the proper terminals. If any
of the wire’s push-on connectors seem loose or corroded, replace the connectors as well. Two “Series” of
Level Control Boards with two different voltage ratings have been used:
 For units E91 to E92, the replacement Level Control Board and is a 120-volt version and is identical to
the original part (Series 16). No wiring changes or modifications are required.
 For units F92 to I93, the replacement Level Control Board is a 240-volt version and will be slightly
different (Series 16 to Series 26). Minor wiring changes are required—see diagram below.
 For units J93 to present, the replacement Level Control Board is a 240-volt version and is identical to the
original part (Series 26). No wiring changes or modifications are required.
