Surface Mounted Thermostats
E32 series medium duty commercial water heaters use only surface mounted thermostats. Surface mounted thermostats are mounted into a bracket which holds the thermostat against the side of the tank. Surface mounted thermostats respond to tank surface temperatures to sense a call for heat, set point temperature settings and high limit (ECO) activation. It is import that the entire back surface of the thermostat is in full contact or flush with the tank. An improperly mounted thermostat will lead to improper heater operation.

SEQUENCE OF OPERATION

E32 series medium duty, field convertible commercial electric water heaters are designed to operate using single phase or three phase service connections. One size fits all Internal fusing is factory installed for all units. When field conversions are required, no fuse change is necessary. Three surface mounted thermostats operating independently
are used to control a corresponding heating element.

Sequence of Operation.

  1. Single phase line voltage is applied across terminals L1 and L2 of terminablock. Or Three phase line voltage is applied to terminals L1 through L3 of terminal block. Line voltage continues through terminal block and fuse blocks and connects to thermostats at terminals L1 & L3.BRADFORD WHITE Medium Duty E32 Series Commercial Electric Water Heaters - Sequence of Operation
  2. ECO (high limit) in thermostat is closed, so there is line voltage present at terminal L4 of thermostats and to one side of each element.BRADFORD WHITE Medium Duty E32 Series Commercial Electric Water Heaters - thermostat is closed
  3. Water in tank is cold, so all thermostats are closed at terminal T2 (calling For heat). This completes the circuit and allows current to flow through heating element.
  4. As each thermostat is satisfied, it opens at terminal T2 interrupting current flow through the respective element. The system is now in stand-by mode, waiting for the next call for heat.

FIELD CONVERSION FOR: KW, Voltage and Phase

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.

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.

NOTICE
Control box conversion is ONLY required when converting water heater to 18kw 208v (Kit# 265-43942-18)
CAUTION
Use caution to not damage any of the wire insulation when removing control box.

Electrical Phase Conversion
Electrical phase conversion will require a change from single-phase to three- phase or an opposite conversion change from three-phase to single-phase. Each of these conversions will be explained separately as follows:

Three-Phase to Single-Phase

  1. Disconnect blue and yellow wires from terminal L-3 of the terminal block
  2. Connect yellow wire to terminal L-1 of the terminal block. The black wires should remain connected to L-1 of the terminal block as it was originally manufactured.
  3. Connect blue wire to terminal L-2 of the terminal block. The red wires should remain connected to L-2 of the terminal block as it was originally manufactured.
  4. Field wiring for the heater power supply will eventually be connected to terminals L-1 and L-2 of the terminal block when the product is installed.

Single-Phase to Three-Phase

  1. Disconnect yellow wire from terminal L-1 of the terminal block
  2. Disconnect blue wire from terminal L-2 of the terminal block
  3. Connect blue and yellow wires to L-3 of the terminal block

TROUBLESHOOTING

Most common cause for improper electric water heater operation can be linked to heating element failure.
When troubleshooting an electric water heater with the incidence of “No Hot Water” or “Insufficient Amount of Hot Water” It is always a good idea to check the heating elements first following the procedure on page 11.
Common Heating Element Failures Are:

  1. Dry Firing. Element may be partially submerged in water or most likely, completely exposed with no water in tank. In some cases sediment or lime build up around an element can eventually cause an air pocket, and within seconds, result in a dry fired element. At this point the element becomes inoperative. When element replacement is required, be sure tank is full of water prior to energizing the water heater.
  2. Grounded Element. An element with a short circuit to ground will in most cases cause the circuit breaker in the service panel to open or shut off. In some cases there may not be enough current draw for the circuit breaker to open. This will allow the heating element to be in continuous operation resulting in over heated water, limited only by the ECO or Energy Cut Off located in the thermostat. Repeated actuation of the ECO reset button on the thermostat usually is the result of a grounded element.
  3. Sediment build up. Slow hot water recovery can usually be traced back to sediment or lime build up around heating element. Sediment build up can also over time cause a dry fired element.

The illustration below shows a common “Screw-In” type heating element identifying certain features commonly referred to throughout this manual.
