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.

CONVERSION GUIDELINES Be sure to read and understand the conversion limitations and instructions prior to conversion. 1. No addition or substraction of heating elements are allowed in the conversion 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; 4. Check all water and electrical connections for tightness after conversion.

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.

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 conversion you have just completed. Peel off the back of the label and paste over the existing rating plate as shown below. SAMPLE RATING PLATE WITH CONVERSION LABEL C. Peel off back of caution label and attach label to upper right hand corner of control panel door. D.

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 disconnected from the circuit. The following table gives resistance in ohms for all elements used in commercial electric water heaters. OHMS RESISTANCE TABLE VOLTAGE WATTAGE 208 240 480 2000 21.63 28.80 115.20 3000 14.42 19.20 76.80 4000 10.82 14.40 57.60 4500 9.61 12.80 51.20 5000 8.65 11.52 46.
