NOTICE
The conversion procedure outlined in this manual is to be executed
ONLY by Qualified Service Personnel. Before attempting conversions
it is recommended that you read the detailed instructions described
herein.
The purpose of this instruction manual is to instruct about the changing of wattage, voltage, and electrical
phase for the commercial electric water heaters manufactured by Bradford White Corporation. Underwriters
Laboratories Inc. recognizes this procedure as herein presented and no deviation from these instructions
are allowed.
Special factory prepared “Conversion Kits” must be used for these conversions. There are separate
conversion kits that have individual instructions and MUST be followed. Page 4 of these instructions lists
the kits that have been prepared for the various wattages and voltages.
These instructions do not allow for a modification that adds or deletes the number of heating elements
originally supplied with the heater; therefore such a modification must NOT
be attempted.
These conversion kits are only applicable to Models E32-50S / E32-80R / E32-120R.
The following information is provided to assist in the successful conversion of the water heater:
