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...

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;
4.  Check all water and electrical connections for tightness after...

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...

V.  PHASE CONVERSION
   A. IMMERSION THERMOSTAT MODEL
      THREE PHASE TO SINGLE PHASE
    1. Disconnect blue wires and yellow wires from terminal L-3.
    2. Connect all blue wires to terminal L-1 (with black wires).
    3. Connect all yellow wires to terminal L-2 (with red wires).
    4.  Incoming power will be connected to 
      terminals L-1 and L-2 at job site.
  
  
  
   B.  IMMERSION THERMOSTAT MODEL 
      SINGLE PHASE TO THREE PHASE
  1.  Disconnect blue wires from terminal L-1.

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. 
 
 C. Peel off back of caution label and attach label to upper right hand corner of c\
ontrol panel door.
  D. CRATE IDENTIFICATION
    Using  a  black  magic  marker,  cross...

 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\
s...
