Introduction
These conversions have been brought into being in order to expedite the water heater replacement activity.
Water heaters suitable for conversion have been wired at the factory to the maximum electrical duty for
which they have been designed. Therefore, internal electrical components are provided that satisfy the
maximum voltage and maximum electrical current conditions
Wattage, voltage, and phase requirements can be readily fitted to the heater. Conversions may involve
altering any one or all of these electrical characteristics.
Required Materials and Tools
• Screw-in element removal wrench --- or --- 1 ½” deep well socket wrench.
• Phillips head screwdriver
• Standard screwdriver
• Conversion Kit that includes: conversion instructions, electrical elements, product label overlay
(related to the newly created electrical parameters), and element gaskets. Refer to page 4 of these
instructions in order to determine the correct Conversion Kit numbers.
Water Heater Preparation
Locate the areas of the carton to be opened opposite the three electrical elements. A dotted line locates
the position on the carton that needs to be scored and cut. Make these three-sided cuts and fold the carton
flap outward to make an opening in the carton. The carton flap will be closed to seal the carton after
conversion is completed. Remove the three element cover screws and the element covers from the water
heater in order to provide access to the elements.
