Field Conversion Of Kw, Voltage And Phase - Bradford White E32-50S Service Manual

The E32 series medium duty commercial electric water heaters are field convertible. This allows Qualified Service
Providers the ability to convert wattage, voltage and phase using a factory supplied conversion kit as required per the
installation. Underwriters Laboratories Inc. recognizes this procedure as herein presented and no deviation from these
instructions are allowed.
KW Conversion
All E32 series medium duty commercial water heaters are factory wired to the maximum electrical duty for which they
have been designed. Therefore, internal electrical components satisfy the maximum voltage and maximum electrical
current conditions.
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.
Special factory prepared "Conversion Kits" must be used for these conversions. These kits contain the heating
elements, element gaskets and product labeling overlays related to the newly created electrical parameters.
18 KW heaters suitable for operation with 208vac cannot be created by conversion since there are no "kits" established
for this electrical system. These heaters can be obtained by ordering directly from the factory.

*265-43942-18 will require control box replacement (included in kit).
Following the heating element removal and replacement instruction on page 16, remove elements and replace with
elements from appropriate kit listed above.
The heaters rating plate will need to be modified because the conversion altered the electrical characteristics of the
heater. This rating plate is placed on every Commercial Electric water heater produced by Bradford White Corporation.
Element kits above contain rating plate label overlays related to the newly created electrical parameters. Follow the
instruction on page 8 For placement of overlays.
Voltage Conversion
1. Voltage conversion is accomplished by replacing the existing elements with elements that are rated at the
required voltage.
2. To accomplish this conversion refer to the above procedure for KW Conversion ---- Element Changes.
Control Box Conversion
1. Open front panel of control box installed on water heater and
disconnect the (6) load wires from fuse blocks.
2. Remove (4) screws joining control box to water heater and
remove control box.
3. Install new control box onto the water heater by feeding the
wires through the back of the control box and reinstall (4)
mounting screws.
4. Reconnect wires to new fuse blocks. Be certain to
match wire colors to Line side of fuse blocks.
