The conversion procedure outlined in the instruction manual is to be executed only by Qualified Service
V
Personnel.
Read these instructions first before proceeding with the conversion.
The purpose of this instruction manual is to instruct about the changing of wattage and voltage for Light
Duty 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 kits must be used for these conversions. Below is a list of the kits that have
been prepared for the various wattages and voltages.
These instructions do not allow for the modification that adds or deletes the number of heating
elements originally supplied with the water heater; therefore such a modification must not be attempted.

10. Thread new element(s) clockwise into tank. Tighten
element(s) with a 1 ½" deep well socket or wrench. Do
not over tighten. Over-tightening may damage gasket.
Note: Clean any debris from element(s) fitting to tank.
Lubricate element(s) threads as needed with thread
lubricant.
