-- IMPORTANT --
Always reference the full model number and serial number when calling the factory.
WARNING / CAUTION
- Tank is to be completely filled with water and all air is to be vented before energizing.
- Due to the rigors of transportation, all connections should be checked for tightness before heater is placed in operation.
-
Safety relief valve must be installed in tapping provided.
-
The refractory material used in heating elements may absorb some moisture during transit, periods of storage, or when subjected to a humid environment. This moisture absorption results in a cold insulation resistance of less than one (1) megohms. If this heater has been subjected to the above condition, each heating element must be checked for insulation resistance before energizing. Contact the factory for a replacement element.
-
KEEP AWAY FROM LIVE ELECTRICAL CIRCUITS.
Do not perform any maintenance, make any adjustments, or replace any components inside the control panel with the high voltage power supply turned on. Under certain circumstances, dangerous potentials may exist even when the power supply is off. To avoid casualties, always turn the power supply safety switch to off, turn the charge or ground the circuit before performing any maintenance or adjustment procedure.
-
The unit is designed to operate at pressure not more than 150 psi.
-
Generalized instructions and procedures cannot anticipate all situations. For this reason, only qualified installers should perform the installations. A qualified installer is a person who has licensed training and a working knowledge of the applicable codes, tools, equipment, and methods necessary for safe installation of an electric resistance water heater. If questions regarding installation arise, check your local plumbing and electrical inspectors for proper procedures and codes. If you cannot obtain the required information, contact the company.
-
Water Quality Requirements – Recommended water hardness is 4 to 6 grains of hardness per gallon (GPG). Water hardness above 6 GPG should be treated by a water conditioner (water softener or in-line treatment). Water hardness below 4 GPG also requires treatment to reduce potential corrosion. Excessive GPG will result in higher operating and maintenance costs and will reduce product longevity. Chlorides must not exceed 50 parts per million (ppm). Excessive chlorides will result in metallic corrosion and will reduce product longevity. Water treatment has been shown to reduce costs associated with de-liming the booster as well as reducing metallic corrosion. Product failure caused by these conditions is not covered under warranty. See warranty for complete details.
-
This water heater is not intended for space heating applications.
-
The water heater is factory set at 185^ F for booster water heating applications. This results in the possibility of a scalding water injury. A full thickness skin burn can occur in less than one second of exposure to water at this temperature.

Load switching is done by a heavy-duty resistive (non-inductive) load type definite purpose magnetic contactor. The contactor supplies power to the heating element(s) when the relay on the control board is closed, thereby pulling in the contacts until the desired temperature is reached. At this point, the contacts will drop out, which in turn disconnects power from the elements. Units with multiple contactors will turn on and off in stages. This contactor is good for 200,000 cycl

WARNING / CAUTION
- DO NOT TURN ON THE ELECTRIC POWER SUPPLY to this equipment until heater is completely filled with water and all air has been released. If the heater is NOT filled with water when the power is turned on, the heating elements will burn out.
- For protection against excessive pressures and temperatures, local codes require the installation of a temperature-and-pressure (T&P) relief valve certified by a nationally recognized laboratory that maintains periodic inspection of production of listed equipment of materials, as meeting the requirements for Relief Valves and Automatic Gas Shutoff for Hot Water Supply Systems. ANSI Z21.22-1971. THE CUSTOMER IS RESPONSIBLE TO PROTECT PROPERTY AND PERSONNEL FROM HARM WHEN THE VALVE FUNCTIONS.
- All water heaters have a risk of leakage at some unpredictable time. IT IS THE CUSTOMER'S RESPONSIBILITY TO PROVIDE A CATCH PAN OR OTHER ADEQUATE MEANS, SO THAT THE RESULTANT FLOW OF WATER WILL NOT DAMAGE FURNISHINGS OR PROPERTY.
- Installation or service of this unit requires ability equal to that of a licensed tradesman in the field.
- The installation must conform to these instructions and any local authority having jurisdiction. Grounding and electrical wiring connected to the unit must also conform to the latest version of the National Electric Code NFPA-70.
WATER HEATER PLACEMENT
NOTE: For most effective operation, install the booster heater as close as possible to the dishwasher. If the distance between the booster and the dishwasher exceeds NSF requirements, recirculation methods must be employed.
-
Place the heater on a solid, level foundation in a clean, dry location as near as possible to the dish washing machine.
-
The water heater should be protected from freezing and waterlines insulated to reduce energy and water waste.
-
Leave a minimum of 18" clearance for element withdrawal and control access.
-
Do not install in an area where flammable liquids or combustible vapors are present.
SLIDE BRACKETS FOR HANGING SUPPORT MOUNTING
- Weld slide rails to bottom of dishtable. Spacing should be 17" for J6 models up to 18kW and 22" for J6 models 24 to 58.5kW. J16 models are not designed for use with slide brackets.

Attach slide bracket angles to heater with #8 sheet metal screws. It will be necessary to drill 1/8" holes into heater jacket for screw pilot holes.
-
Slide heater onto slide rails under dishtable.
PIPING INSTALLATION - See Diagrams
NOTES:
- No check valve may be installed in the supply line to the booster.
- All shut-off valves must be gate or ball valves – not globe valves.
- To minimize heat loss and maximize efficiency, hot water piping should be insulated.
-
Teflon tape should be used on all NPT threaded pipe connections.
-
Install the optional dielectric unions on the inlet and outlet piping.
-
Connect the cold/warm water inlet and hot water outlet to the appropriate connections as shown; refer to the specifications for location and sizes.
IMPORTANT – Be certain to connect the outlet piping to the final rinse and not to the wash tank. Insulate if over 3 feet.
IMPORTANT (applies to J6 Models only) – Do not turn the entering warm water or exiting hot water nipples from their factory installed positions. The internal diffusers are aligned at the factory and turning the nipple will change the diffuser position and affect performance. Hubbell recommends that the inlet and outlet pipes are insulated to prevent excessive heat loss.
IMPORTANT (applies to J6 Models only) – Do not apply heat directly to the entering warm water or exiting hot water nipples. If sweat connections are to be used, sweat tubing to the adapter before threading the adapter to the nipple on the heater. Any heat applied to the heater nipple will damage the internal plastic diffuser and affect performance.
- Install the pressure reducing valve in the entering cold/warm water inlet line and adjust to 20-psi. The standard PRV comes preset to 25psi. The optional brass PRV is preset to 50psi and must be adjusted to 25psi. The set screw located at the top of the diaphragm adjusts the pressure, turn clockwise to increase the pressure and counterclockwise to decrease the pressure. NOTE: Be sure to install the valve with flow in the proper direction as indicated by the directional arrow on the valve. IF A STANDARD PRESSURE REGULATOR IS USED, it acts as a check valve and it is possible that thermal expansion will cause the relief valve to drip or occasionally blow off a small amount of water. To overcome this condition, it is recommended that a 3/8" by-pass arrangement with a horizontal check valve be installed around the pressure regulator. This will prevent annoyance caused by the relief valve dripping or blowing off.
NOTE: It is strongly recommended that a pressure reducing valve with built-in bypass is installed in models where one is not supplied.
- Install the combination temperature and pressure safety relief valve in the tapping provided. Note that this is required by law for safety considerations.

- Open the valve to the cold/warm water inlet and allow the heater and piping system to completely fill, as indicated by a steady flow of water through the dishwasher rinse nozzles.
NOTE: Flush the tank at full flow for 10 minutes prior to putting into service.
ELECTRICAL INSTALLATION
-
Enter the base through the factory cut KO's with properly sized feeder leads, See Wiring Chart. Single-phase installations require two (2) leads. All Hubbell 3-phase heaters are intended for use with a 3-wire delta system plus ground. No neutral is required. For a 4-wire plus ground system, install 3 legs of power plus the ground and terminate the neutral leg.
-
Install these power leads into the box lugs on the power distribution block or magnetic contactor, as required.
-
Connect incoming ground wire to ground lug supplied.
-
Check for proper grounding. Check for AC millivolts (mV) between the ground connection at the booster and the inlet piping past the optional dielectric union (on the building side, not the booster side). There should be zero potential/millivolts (mV). If not zero, then the piping should be re-grounded.
-
All other electrical connections are made at the factory; therefore, no other electrical connections are necessary.
-
Check all connections, including factory connections, for tightness.
OPTIONAL XB1 EXPANSION BOARD (used for temperature alarm / interlock)
-
If desired, the XB1 can be used as an alarm relay or a temperature interlock at a setpoint other than the water temperature setpoint on the booster heater.
-
If the XB1 is not factory installed, mount the XB1 to the control panel and connect the XB1 to the T1000 control board with the factory supplied cable between JX4 on the XB1 and J1 and J4 on the T1000 and connect the ground between JX6 on the XB1 and J8 on the T1000.
-
Make connections as required to the relay term inal block. When the temperature drops below the XB1 setpoint the relay is open between Normally Open (NO) and Common
(C) and the LED will flash green. When the temperature is above the XB1 setpoint the relay is closed between NO and C and the LED will be solid green. Use NO and C for low temperature interlock or high temperature alarm. Use Normally Closed (NC) and C for low temperature alarm. A red LED indicates an error.

Use a NO (Normally Open) relay to turn the booster OFF when energizing the relay coil or to turn the booster ON when de-energizing the relay coil.
OPTIONAL REMOTE ALARM CONTACTS
- If desired, the control board can be wired to a remote alarm to indicate a reset fault condition. These fault conditions include over-temperature, no probe, and low water (when the configuration is set to manual reset).
- This alarm can be wired to the J4 connector on the control board as shown below. To facilitate this installation, an optional adapter, Hubbell P/N PLUG ADAPTER J4, can be purchased to provide wire connections.

J4 Connector PLUG ADAPTER J4 Note: Rating (resistive) Max. Switching Power: 60W, 62.5VA Max. Switching Voltage: 220VDC, 250VAC Max. Switching Current: 2A Max. Carrying Current: 3A Common (NO) (NC)Note: That when the XB1 expansion board is used, the J4 PLUG ADAPTER should plug into the JX1 connection on the XB1.
OPTIONAL FIELD CONVERSION FROM SINGLE TO THREE PHASE OR THREE TO SINGLE PHASE (J6 and J16 models in 6, 7, and 9 kW at 208 and 240 volts and J411 models only)
- Re-wire the unit to desired configuration as indicated below.
NOTE: The wire to be used for internal wiring must conform to SEW-2 or PTFE (200°C) and must match the wire size currently in use. Contact the factory for assistance, if required.
- Contact the factory for correct labels. The factory will need the serial number for proper identification.
-
If desired, the heater can be wired to operate only when supplied with a 24-volt signal through the heater interlock adapter. When no 24-volt signal is supplied through the heater interlock adapter the heater is interlocked and will not energize. When interlocked the display will show “III.d”. The heater will resume normal operation when a 24-volt signal is re-applied through the heater interlock adapter.
-
To utilize this feature, plug the 24-volt heater interlock adapter into terminal J1 of the T1000 control board (note: if the XB1 expansion board is used, plug the adapter into terminal JX3 of the XB1) and verify that the configuration is set to "Hon", see the controller operation section for further detail. The signal can be either AC or DC. However, if a DC signal is utilized and the interlock feature does not operate, switch the two 24-volt supply wires at the heater interlock adapter.

Setpoint 18.5 2nd Contactor (if supplied) 1st ContactorANNUAL INSPECTION
- Monitor water temperature
a. Let water heater com pletely heat to a designated temperature setting.
b. After controller satisfies (that is, when the magnetic contactor actually clicks off), draw water from as close as possible heater outlet and measure the temperature.
c. Compare the water temperature of outlet water to the temperature setting of the display when it satisfies. Normal variation between the two points is approximately ±5^ F.
d. If these two readings do not coincide within acceptable tolerances and verification has been made of the accuracy of the temperature-reading gauge, replace the control board and/or the sensor probe.
-
Lift test lever on relief valve and let water run through valve for a period of approximately 10 seconds. This will help flush away any sediment that might build up in water passageways.
-
Inspect element for leakage as follows:
a. Shut off power supply.
b. Remove front cover.
c. Visually inspect around heating element for evidence of leaks.
d. Rub around the heating element with a rag. Check for any evidence of moisture. If moisture is present or a water drip is observed, follow procedure outlined in Section V.
CAUTION: The area around the heating element may be hot.
- Scale and mineral build-up on heating elements is a normal condition. It is recommended that the heating element be removed for examination and if scaled, should be cleaned. In an area of known hard or poor water conditions, the elements may need to be checked more frequently. This will improve the efficiency of the heater and increase the element life.
NOTE: Failure of the elements due to scale and mineral build-up is not covered under warranty. See warranty for complete details.
a. Shut off power supply.
b. Drain the tank.
c. Remove front cover.
d. Disconnect the element wiring. It is recommended that one element at a time is removed to simplify re-wiring.
e. Unscrew element.
f. Lime scale removal
i. Place limed ends of the heating element in a de-limer solution, designed for potable water applications, and allow lime to dissolve. Do not allow de-limer to contact heating element terminals.
g. Other scale removal
i. Silicates, sulfates, and aluminates must be removed by scraping or other mechanical means. De-limers will not dissolve these types of scale.
h. Flush the cleaned ends of the elements with clean water.
i. Re-install element with new o-ring.
j. Re-attach element wires.
k. Continue until all heating elements are cleaned.
- Fill the heater following the filling instructions provided in Section II and check around the elements for leaks.
m. Re-apply power.
- Check for loose electrical connections. Tighten as necessary.
SECTION IV - TROUBLESHOOTING
ERROR MESSAGES

a. This message will flash when the controller does not detect that the probe is connected to the control board. To clear this error reinsert the probe connector and press RESET.
- Err, too, hot, ### (where ### is the actual temperature of the water.)
a. This message will display if the temperature of the water exceeds the high limit temperature setpoint. To clear this error, wait until the temperature is below the operating setpoint and press RESET. Note that the unit will not reset until the indicated temperature is below 195^ F. If this message continually occurs, follow the troubleshooting flow chart for continuous over-temperature condition.
- Err, No, H20
a. This message will display when the water level in the tank has dropped below the sensor probe. To clear this message, refill the tank. If the low water reset is set for automatic, the error will clear. If the low water reset is set for manual, when the tank is full press RESET. Check the heater and the piping for leaks. Check for mineral buildup on the probe and clean as required. Check for continuity between the yellow wire and ground. See diagram 2 on the following page.
- Err, H2O, LEA
a. This message displays if the leak detection sensor determines there is water in the base of the heater shell. To clear this message, remove the water from the leak detection sensor. Check the unit and piping for leaks.
- CC
a. This message displays if the display cable is installed into the control board backwards. To clear this message, remove and correctly install the display cable.
6.255
a. This message indicates that the probe is likely out of calibration. To clear this message, it is recommended that the probe be removed and replaced.
- HLD
a. This message indicates that the 24-volt interlock feature is enabled, there is no 24-volt signal present, and the heater is in standby mode. If it is not the intention to operate the heater with the 24-volt interlock feature, this feature should be disabled as shown in the controller operation section. (Only available with r23 or later software).
CONTACTOR CARE
- A chattering or humming from the contactor is due to dust or debris on the contact points that prevents the contactor from making proper contact. The debris can be removed by utilizing a can of antistatic cleaning and dusting spray (pressurized air) and spraying through the side of the contactor to remove the debris.
DISPLAY BUTTONS
- If the display randomly changes or does not respond when the buttons are pressed, loosen the four (4) screws holding the display to the base, reseat the display in the center of the opening, leaving the screws loose.
MISCELLANEOUS
- If the display flashes when the unit is first turned on or turned on after maintenance, check that the J5 terminal on the controller is engaging all four pins on the board.
- Note that before replacing the control board, display, or probe, it is recommended that the power supply to the booster heater be turned off at the main circuit breaker disconnect to the booster heater to reset and clear the electronic controller.
CAUTION: Do not use plumber's tape/Teflon tape/pipe dope when installing the probe. Tape will prevent the low water detection system from operating properly and will cause false low water errors. Lubricate O-ring prior to installation.
| Symptom | Probable | Cause Corrective Action |
| Water reaches setpoint temperature but does not last through the entire dishwasher cycle. | Low incoming water temperature. | Incoming water temperature must be adequate for the booster size. Increase the incoming water temperature. |
| Incoming water temperature is dropping. | Primary water supply is not adequate to continually provide correct temperature in sufficient quantities. Increase the supply of primary warm water. | |
| Water pressure is too high. | Higher water pressure uses an excessive supply of hot water. Verify a pressure reducing valve is installed and adjust the water pressure to 20 psi. | |
| Booster heater may be undersized. | The booster heater must be properly sized for the incoming water and rinse requirements of the dishwasher. If required, replace with a properly sized unit. | |
| Incorrect voltage. Voltage | Available at the booster heater must be correct for unit. Verify voltage on all phases matches nameplate on the booster heater. | |
| If two magnetic contactors are utilized, one is not energizing. | Verify that both magnetic contactors are operating. If not, see the ‘Magnetic Contactor Troubleshooting’ section. | |
| One or more elements are not energizing. | Verify that each element is drawing the correct amperage. Replace elements as required. | |

If a transformer is installed, verify proper power supply voltage to the primary side of the transformer and verify approximately 240VAC on the secondary side of the transformer. If voltage is present of the primary side but not on the secondary side, replace the transformer.
-
If circuit breakers are installed, verify that the circuit breaker is ON. Verify proper power supply voltage between each phase (L1 to L2, L2 to L3, and L1 to L3) to the line side of each circuit breaker and to the load side of each circuit breaker. If voltage is present of the line side but not on the load side, replace the circuit breaker.
-
Verify that the booster heater is wired according to the proper wiring schematic for the unit. Correct as required. If unit still does not operate, contact the factory.
MAGNETIC CONTACTOR TROUBLESHOOTING
-
With the unit ON and calling for heat, check for lit decimal points on the display. If the unit has a single contactor, the first decimal to the right of the display should be lit. If two decimals are lit, verify that the configuration is set for one contactor. If the unit has two contactors, verify that two decimals are lit. If only one decimal is lit, verify that the configuration is set for two contactors. If no decimals are lit, continue to the 'P65 Probe Troubleshooting' section.
-
With the unit ON and calling for heat and one decimal lit, check for 240VAC between pin 1 (white wire) and pin 4 (yellow wire) of the J5 connector on the T1000 control board. If no voltage is present, replace the control board (T1000). If voltage is present, check for voltage across the contactor coil. If voltage is present at the contactor coil, replace the magnetic contactor. If no voltage is present, verify that the booster heater is wired according to the proper wiring schematic for the unit.
-
If the unit has two contactors, with the unit ON and calling for heat and two decimals lit, check for 240VAC between pin 1 (white wire) and pin 3 (red wire) of the J5 connector on the T1000 control board. If no voltage is present, replace the control board (T1000). If voltage is present, check for voltage across the contactor coil. If voltage is present at the contactor coil, replace the magnetic contactor. If no voltage is present, verify that the booster heater is wired according to the proper wiring schematic for the unit.
P65 PROBE TROUBLESHOOTING
- Unplug and reseat the P65 probe wire in the jack on the T1000 control board. Note that the error message “Err, No, Prb” will be displayed and the reset button must be pressed to clear the message.
- If problem persists, unplug the P65 probe from the control board and plug into the RJ45 pigtail (not supplied).
- If the problem is with temperature control or high limit:
a. Change the configuration to 'dS t' to display the actual water temperature.
b. Check the temperature of the water with a thermometer and compare that with the temperature on the display. If the two temperatures coincide, replace the T1000 control board. If the two temperatures do not coincide, continue to the next step.
c. Unplug the P65 probe from the control board and plug into the RJ45 pigtail (not supplied). Check the resistance value (ohms) between the blue wire of the pigtail (#1) and the red wire of the pigtail (#4). Compare the resistance value measure with the chart below at the measured temperature of the water. If the two values coincide, replace the T1000 control board. If the two values do not coincide, replace the P65 sensor
- If the problem is with low water:
a. Verify that the unit is filled with water.
b. Check for continuity between the yellow wire of the pigtail (#2) and ground. If continuity exists, replace the T1000 control board. If no continuity exists, replace the P65 sensor probe.
