FOREWORD
The purpose of this manual is to explain how to change the voltage and wattage of your commercial electric water \
heater
by changing the elements. This manual is not intended to explain the rebuilding of commercial electric water heaters
in the field.
Addition of heating elements or subtraction of heating elements in the field is not approved by Underwriters Laboratories,
Inc., and therefore, is not allowed and should not be attempted.
Please note the limitation that “both the heater...](http://img.usermanuals.tech/thumb/388/5721/w64_heavyduty-commercial-electric-conversion-kit-instructions-stce-itce-1478788741_d-1.png "Page 2

CONVERSION GUIDELINES
Be sure to read and understand the conversion limitations and instructio\
ns prior to conversion.1. No addition or substraction of heating elements are allowed in the conve\
rsion process;
2. Conversion kits are designed for specific voltage with Delta configuration, no other configuration or voltage is
allowed;
3. Refer to “Branch Circuit Section” in User’s Manual for electrical specifications;

CONVERSION INSTRUCTIONS
REQUIRED ABILITY
CONVERSION OF ANY WATER HEATER LISTED IN THIS MANUAL REQUIRES ABILITY EQUIVALENT TO THAT OF A LICENSED ELECTRICAL TRADESMAN
I. INTRODUCTION
Satisfying a customer order for a commercial electric heater from inventory may require modification to the KW input,
the voltage, or the phase. Conversions may involve revision to 1, 2, or \
all 3 of these electrical characteristics.
II. HEATER PREPARATION
The heater should be placed in a well lit area. Complete removal...](http://img.usermanuals.tech/thumb/388/5721/w64_heavyduty-commercial-electric-conversion-kit-instructions-stce-itce-1478788741_d-3.png "Page 4

The voltage, element KW, total KW data of the rating plate must be modified by covering them with the label provided in
the conversion kit. Be sure the new ratings on the label match the conv\
ersion you have just completed.
Peel off the back of the label and paste over the existing rating plate as show\
n below.

B. ELEMENT SIZE VERIFICATION
All elements are marked with both wattage and voltage. Verification can be made by measuring the ohms
resistance across the terminals of the elements. Element must be discon\
nected from the circuit. The following
table gives resistance in ohms for all elements used in commercial elect\
ric water heaters.
Element ohms resistance should be within ±5% of the above values.
Examples: Elements with an ohm resistance of 14 ohms indicates that it i\
