Hatco Electric Booster Water Heaters are a product of extensive research and field testing. The materials used were selected for maximum durability, attractive appearance and optimum performance. Every unit is thoroughly inspected and tested prior to shipment.

IMPORTANT! Read the following important safety instructions to avoid personal injury or death, and to avoid damage to the equipment or property.

⚠️ WARNINGS

To avoid personal injury or damage to equipment, the booster heater must be installed by qualified, trained installers. Installation must conform to all local electrical and plumbing codes. Check with your local plumbing and electrical inspectors for proper procedures and codes.
To avoid any injury or damage to the booster heater turn the power OFF at the disconnect switch/circuit breaker and allow to cool before performing any maintenance or adjustments.
⚠ For proper electrical installation conforming to local electrical codes and the National Electrical Code (N.E.C.), consult a licensed electrical contractor.
To avoid injury or damage to dishwashing equipment do not connect Hatco Electric Booster Water Heaters to domestic (consumer) dishmachines or other domestic utilized equipment.
To avoid any injury or damage to equipment and to assure proper operation do not connect an expansion tank of any type to booster heater water lines.
To avoid personal injury or damage to the Hatco Electric Booster Water Heater, only use plumbing material suitable for a minimum water temperature of 200°F (93°C). Materials used must meet National Sanitation Foundation (NSF) specifications and all local plumbing codes and regulations.
To avoid personal injury or damage to the unit aftermarket covers must not be placed on or over the booster heater. Doing so can cause temperature and moisture build-up resulting in premature failure and electrical shock.
It is essential to recognize that even though a water heater may be properly installed initially and approved, there always exists the possibility that unknowing individuals might alter or change the installation in a manner that would render it unsafe. Therefore, it is important that all safety programs provide some mechanism to assure that these installations are inspected periodically.

! WARNINGS

Hatco has always endorsed the use of safety equipment when using a booster water heater or storage-type water heater. Hatco booster heaters are shipped with a temperature/pressure relief valve at no extra charge. This valve must be installed into the marked opening provided in the tank. Valves supplied by Hatco are designed for high temperature commercial operation. Do not substitute Hatco supplied valves with valves designed for domestic operation.
Temperature/pressure protective equipment should not be less than a combination temperature/pressure relief valve certified by a nationally recognized testing laboratory that maintains periodic inspection of the production of this equipment and meets the requirements for Relief Valves and Automatic Shutoff Devices for Hot Water Supply Systems, ANSI Z21.22-1979. The temperature/pressure relief valve must be marked with a minimum set pressure not to exceed the marked hydrostatic test pressure of the booster heater as noted on the unit specifications.
To avoid personal injury or damage to the equipment make sure the dishtable is strong enough to support the weight of the booster heater and water when installing with slide mounting brackets.
To avoid personal injury or damage to the equipment, follow standard welding procedures when attaching sliderails to bottom of dishtable.
⚠️ Water in the unit is very hot. Wear protective gloves and proper attire when operating to avoid injury.
To assure proper operation and avoid a possible unsafe condition, the booster heater must be installed in a horizontal position with the base parallel to the floor and the inlet connection at the lowest point.
This product contains fiberglass, a product known to the state of California to cause cancer, birth defects or other reproductive harm.
To avoid any injury or damage do not install the unit in an area where flammable liquids or combustible vapors are present.

IMPORTANT! Read the following important safety instructions to avoid personal injury or death, and to avoid damage to the equipment or property.

⚠️ WARNINGS (CONTINUED)

FOR INSTALLING PRESSURE AND TEMPERATURE RELIEF VALVES IN ACCORDANCE WITH AMERICAN NATIONAL STD. Z21.22-1979. Combination pressure and temperature relief valves with extension thermostats must be installed so that the temperature-sensing element is immersed in the water within the top 6" (152 mm) of the tank. They must be installed either in the hot outlet service line or directly in a tank tapping. Combination pressure and temperature relief valves that do not have extension elements must be mounted directly in a tank tapping located within the top 6" (152 mm) of the tank, and shall be adequately insulated and located so as to assure isolation from the flue gas heat or other ambient conditions that are not indicative of stored water temperature. TO AVOID WATER DAMAGE OR SCALDING DUE TO VALVE OPERATION, DRAIN PIPE MUST BE CONNECTED TO VALVE OUTLET AND RUN TO A SAFE PLACE OF DISPOSAL. Discharge line must be as short as possible and be the same size as the valve discharge connection throughout its entire length. Drain line must pitch downward from the valve and must terminate between 1-1/2" (38 mm) and 6" (152 mm) above the floor drain where any discharge will be clearly visible. The drain line shall terminate plain, not threaded, with material serviceable for temperatures up to 250°F (121°C) or greater. Excessive length, over 30' (9144 mm), or use of more than four elbows can cause a restriction and reduce the discharge capacity of the valve. No shut-off valve shall be installed between the relief valve and tank, or in the drain line. Valve lever must be tripped periodically to assure that waterways are clear. This device is designated for emergency safety relief and shall not be used as an operating control. The valves are set to relieve at 150 psi (1034 kPa) or when water temperature reaches 210°F (99°C). Read tag on valve for additional information.

⚠️ To avoid any injury or damage, the booster heater must only be serviced by qualified personnel.

⚠️ WARNINGS

Valves supplied by Hatco are designed for high temperature commercial operation. Do not substitute Hatco valves with valves designed for domestic water heaters.
⚠️ Units are equipped with a High Temperature Limit Safety Switch that will shut the power off if the unit overheats. To avoid any injury to personnel or damage to the unit, contact an Authorized Hatco Service Agent if the High Temperature Limit Safety Switch cannot be reset or continues to trip.
To avoid personal injury and to assure safe operation install the booster heater as close as possible to the commercial dishwasher. Employ recirculation if distance between booster and commercial dishwasher exceeds National Sanitation Foundation (NSF) specifications of five (5) linear feet (1524 mm).
To avoid personal injury and avoid damage to the booster heater refer to BOOSTER HEATER SIZING CHART in this manual.
If service is required on this unit, contact your Authorized Hatco Service Agent, or contact the Hatco Service Department at 800-558-0607 or 414-671-6350; fax [phone] or International fax [phone].
This product has no "user" serviceable parts. To avoid damage to the unit or injury to personnel, use only Authorized Hatco Service Agents and Genuine Hatco Replacement Parts when service is required.
Genuine Hatco Replacement Parts are specified to operate safely in the environments in which they are used. Some aftermarket or generic replacement parts do not have the characteristics that will allow them to operate safely in Hatco equipment. It is essential to use Hatco Replacement Parts when repairing Hatco equipment. Failure to use Hatco Replacement Parts may subject operators of the equipment to hazardous electrical voltage, resulting in electrical shock or burn.

IMPORTANT! Read the following important safety instructions to avoid personal injury or death, and to avoid damage to the equipment or property.

CAUTIONS

To assure proper operation do not use antisiphon or check valve on the incoming water line.
Do not connect the heater directly to a boiler or furnace coil or any other uncontrolled temperature source, or the thermostat could be damaged causing the unit to overheat.
Unit is not weatherproof. For safe and proper operation the unit must be located indoors where the ambient air temperature is constant and is a minimum of 70^ F ( 21^ C).

CAUTIONS

Hatco requires that two temperature/pressure gauges, Hatco part number 03.01.003.00, be installed to assure proper operation. Install one in the supply line before the pressure reducing valve and one in the outlet line as close to the booster heater as possible. This provides a visual check of the water temperature and pressure before and after the water heater.

If water supply pressure to the booster inlet is over 20 psi (138 kPa) during flow, install Hatco pressure reducing valve with built-in bypass, Hatco part number 03.02.004.00, for proper operation of dishwater rinse nozzles.

NOTE: The pressure reducing valve must be the type equipped with a high pressure bypass as supplied by Hatco.

Do not turn on power to the booster heater until the tank has been filled with water and all air has been vented through the dishwasher rinse nozzle. The heating elements will burn out in seconds if operated when they are not immersed in water.

To assure proper operation on all Large Compact Series units, (C-24 to C-57), do not turn or adjust outlet water connection.

CAUTIONS

To prevent electrolysis or plumbing damage dielectric couplings should be used in connecting dissimilar metals, such as galvanized to copper.

To avoid possible leaks, do not back out or loosen any pipe fitting.

Do not lay unit on the side with the control panel or damage to unit could occur.

To avoid damage to the unit always drain the booster heater with power to the unit off, or element burnout could occur.

Incoming water in excess of 3 grains of hardness per gallon ([GPG] .75 grains of hardness per liter [GPL]) must be treated and softened before being supplied to booster heater(s). Water containing over 3 GPG or .75 GPL will decrease efficiency, increase energy use, and reduce the operating life of the unit through increased lime build-up. Product failure caused by liming or sediment buildup is not covered under warranty.

To assure proper performance Hatco Electric Booster Water Heaters are only to be connected to the same power supply as indicated on the specification decal. Units connected to an incorrect power supply voids the product warranty and may damage the equipment.

To assure proper operation on all Compact Series Booster Heaters, do not turn or adjust inlet water connection on unit. Doing so will change the internal water flow.

Only 6, 7 & 9 kW models can be field converted to single or three phase (open delta on 3 phase). Larger branch circuit required than for balanced 3 phase of equal kW. Balanced 3 phase available, consult factory.
NOTE: 250 kcmil maximum wire size for terminal block.

Figure 7. Components Shipped with the Heater Unit

WARNING

To assure proper operation and avoid a possible unsafe condition, the booster heater must be installed in a horizontal position with the base parallel to the floor and the inlet connection at the lowest point.

WARNING

This product contains fiberglass, a product known to the state of California to cause cancer, birth defects or other reproductive harm.

PRESSURE AND TEMPERATURE RELIEF VALVES

For protection against excessive pressures and temperatures in the booster heater, install temperature and pressure protective equipment required by local codes. Hatco supplies temperature and pressure relief valves constructed with brass working parts and heat resistant silicone seat discs for all booster heater models.

WARNING

Valves supplied by Hatco are designed for high temperature commercial operation. Do not substitute Hatco valves with valves designed for domestic water heaters.

WARNING

Temperature/pressure protective equipment should not be less than a combination temperature/pressure relief valve certified by a nationally recognized testing laboratory that maintains periodic inspection of the production of this equipment and meets the requirements for Relief Valves and Automatic Shutoff Devices for Hot Water Supply Systems, ANSI Z21.22-1979. The temperature/pressure relief valve must be marked with a minimum set pressure not to exceed the marked hydrostatic test pressure of the booster heater as noted on the unit specifications.

WARNING

FOR INSTALLING PRESSURE AND TEMPERATURE RELIEF VALVES IN ACCORDANCE WITH AMERICAN NATIONAL STD. Z21.22-1979. Combination pressure and temperature relief valves with extension thermostats must be installed so that the temperature-sensing element is immersed in the water within the top 6" (152 mm) of the tank. They must be installed either in the hot outlet service line or directly in a tank tapping. Combination pressure and temperature relief valves that do not have extension elements must be mounted directly in a tank tapping located within the top 6" (152 mm) of the tank, and shall be adequately insulated and located so as to assure isolation from the flue gas heat or other ambient conditions that are not indicative of stored water temperature. TO AVOID WATER DAMAGE OR SCALDING DUE TO VALVE OPERATION, DRAIN PIPE MUST BE CONNECTED TO VALVE OUTLET AND RUN TO A SAFE PLACE OF DISPOSAL. Discharge line must be as short as possible and be the same size as the valve discharge connection throughout its entire length. Drain line must pitch downward from the valve and must terminate between 1-1/2" (38 mm) and 6" (152 mm) above the floor drain where any discharge will be clearly visible. The drain line shall terminate plain, not threaded, with material serviceable for temperatures up to 250°F (121°C) or greater. Excessive length, over 30' (9144 mm), or use of more than four elbows can cause a restriction and reduce the discharge capacity of the valve. No shut-off valve shall be installed between the relief valve and tank, or in the drain line. Valve lever must be tripped periodically to assure that waterways are clear. This device is designated for emergency safety relief and shall not be used as an operating control. The valves are set to relieve at 150 psi (1034 kPa) or when water temperature reaches 210°F (99°C). Read tag on valve for additional information.

CAUTION

To assure proper operation do not use an anti-siphon or check valve on the incoming water line.

PRESSURE REDUCING VALVE

CAUTION

If water supply pressure to the booster inlet is over 20 psi (138 kPa) during flow, install Hatco pressure reducing valve with built-in bypass, Hatco part number 03.02.004.00, for proper operation of dishwater rinse nozzles.

NOTE: The pressure reducing valve must be the type equipped with a high pressure bypass as supplied by Hatco.

Proper operation of the commercial dishwasher rinse nozzles requires available water pressure at the rinse nozzle be between 15 and 25 psi (103 and 172 kPa) when nozzle is operated. 20 psi (138 kPa) is recommended. If water pressure available to the booster heater inlet is over 20 psi (138 kPa), a pressure reducing valve must be installed in the hot water supply line to the booster heater and adjusted to deliver 20 psi (138 kPa) flow pressure.

The valve supplied by Hatco with the unit, Hatco part number 03.02.004.00, has a built-in high pressure bypass which prevents excessive pressure build-up as the booster heats up. Final adjustment required at time of installation.

TEMPERATURE/PRESSURE GAUGES

CAUTION

Hatco requires that two temperature/pressure gauges, Hatco part number 03.01.003.00, be installed to assure proper operation. Install one in the supply line before the pressure reducing valve and one in the outlet line as close to the booster heater as possible. This provides a visual check of the water temperature and pressure before and after the water heater.

NOTE: If a check valve is installed and cannot be removed install a back pressure relief valve, Hatco part number 03.02.039.00, set at 125 psi (862 kPa) on the incoming line between the pressure reducing valve and the inlet to the booster heater. Discharge must be to open site drain. (See Figure 13.)

BLENDED PHOSPHATE WATER TREATMENT SYSTEM (OPTIONAL)

Hatco recommends that the Blended Phosphate Water Treatment System be installed with unions on the incoming 3/4" water supply line after the pressure reducing valve and before the booster heater.

Cartridges supplied have a usage rating of 100,000 gallons (378,541 liters) of water. To assure proper operation the cartridges must be replaced when expired.

NOTE: Product failure caused by liming or sediment buildup is not covered under warranty.

PLUMBING CONNECTIONS

CAUTION

To avoid possible leaks, do not back out or loosen any pipe fittings.

CAUTION

Do not connect the heater directly to a boiler or furnace coil or any other uncontrolled temperature source, or the thermostat could be damaged causing the unit to overheat.

WARNING

To avoid injury or damage to dishwashing equipment do not connect Hatco Electric Booster Water Heaters to domestic (consumer) dishmachines or other domestic utilized equipment.

WARNING

To avoid any injury or damage to equipment and to assure proper operation do not connect an expansion tank of any type to booster heater water lines.

WARNING

To avoid personal injury or damage to the unit aftermarket covers must not be placed on or over the booster heater. Doing so can cause temperature and moisture build-up resulting in premature failure and electrical shock.

WARNING

To avoid personal injury or damage to the Hatco Electric Booster Water Heater, only use plumbing material suitable for a minimum water temperature of 200^ F ( 93^ C). Materials used must meet National Sanitation Foundation (NSF) specifications and all local plumbing codes and regulations.

Inlet

Refer to Figure 8, 9, 10, 11 or 12.

1. Connect the booster water inlet to a hot water supply line from the regular water heater. Water temperature from the regular water heater should be 110^ or 140^ F ( 43^ or 60^ C) and should not exceed 160^ F ( 71^ C). Minimum temperature differential between inlet and outlet should never be less than 20^ F ( 11^ C).

NOTE: Refer to BOOSTER HEATER SIZING CHART for application information.

WARNING

To avoid personal injury and avoid damage to the booster heater refer to BOOSTER HEATER SIZING CHART in this manual.

CAUTION

To assure proper operation on all Compact Series Booster Heaters, do not turn or adjust inlet water connection on unit. Doing so will change the internal water flow.

NOTE: Red mark on inlet water pipe of Compact series units must remain in the top most position.

CAUTION

To prevent electrolysis or plumbing damage dielectric couplings should be used in connecting dissimilar metals, such as galvanized to copper.

CAUTION

To avoid possible leaks, do not back out or loosen any pipe fitting.

CAUTION

Incoming water in excess of 3 grains of hardness per gallon ([GPG] .75 grains of hardness per liter [GPL]) must be treated and softened before being supplied to booster heater(s). Water containing over 3 GPG or .75 GPL will decrease efficiency, increase energy use, and reduce the operating life of the unit through increased lime build-up. Product failure caused by liming or sediment buildup is not covered under warranty.

NOTE: Product failure caused by liming or sediment buildup is not covered under warranty.

1. Provide the inlet line with a shut-off valve, (a full opening gate or ball type), one temperature/pressure gauge, and the pressure reducing valve. Set pressure reducing valve at 20 psi (138 kPa) flow pressure.

NOTE: A 3/4" union and a drain valve are required for easy servicing.

NOTE: Be sure water flows through the pressure reducing valve in the proper direction. Check directional arrow. Valve will reduce pressure only during flow conditions.

1. Install a temperature/pressure gauge in both the inlet and outlet lines. Install the temperature sensing bulb in the water stream. The gauge must be mounted upright. (See Figures 14 and 15.)

NOTE: Tighten gauge during installation by only turning the 1/2" brass nut. DO NOT turn the face of the gauge. Turning the face will cause inaccurate measurements.

NOTE: Some dishmachines require two booster heaters be plumbed in series (not parallel) to meet the demand. (See Figure 9.) To assure proper operation a 20^ F ( 11^ C) temperature differential must be maintained between the outlet of the first booster heater and the inlet of the second booster heater.

Outlet

1. Using a 3/4" union and piping, connect the booster heater water outlet to the commercial dishwasher sanitizing rinse pipe connection.

CAUTION

To assure proper operation on all Large Compact Series units, (C-24 to C-57), do not turn or adjust outlet water connection.

NOTE: Red mark on outlet water pipe for C-24 to C-57 series units must remain in the top most position.

NOTE: Be certain the connection is made to the final rinse and not to the wash tank.

1. Install a temperature/pressure gauge in the outlet line. The temperature sensing element must be in the water stream and the gauge must be mounted upright. Water temperature at the outlet should be 185^-190^ ( 85^-88^ ). (See Figure 14 or 15.)

NOTE: Some dishmachines require two booster heaters be plumbed in series (not parallel) to meet the demand. (See Figure 9.) To assure proper operation a 20^ F ( 11^ C) temperature differential must be maintained between the outlet of the first booster heater and the inlet of the second booster heater.

NOTE: Hatco recommends installing an optional shock absorber, Hatco part number 03.04.057.00, in the outlet line as close as possible to the commercial dishwasher solenoid rinse valve. The shock absorber softens the water hammer caused by automatic dishwasher valves.

Plumbing Installation Inspection

1. Close drain pipe valve and fill booster heater with water.
2. Check all pipe connections for leaks.
3. Make sure relief valve discharge is not blocked.
4. Vent air from tank before operating by opening temperature/pressure relief valve.

CAUTION

Do not turn on power to the booster heater until the tank has been filled with water and all air has been vented through the dishwasher rinse nozzle. The heating elements will burn out in seconds if operated when they are not immersed in water.

WARNING

To avoid any injury or damage, the booster heater must only be serviced by qualified personnel.

WARNING

To avoid any injury or damage to the booster heater turn the power OFF at the disconnect switch/circuit breaker and allow to cool before performing any maintenance.

GENERAL

IMPORTANT! Many times when a booster heater does not appear to be functioning properly, the fault is not with the booster heater itself but with factors outside the heater. Before proceeding with the troubleshooting chart on pages 31-33, perform the following steps first, then review the information on the next page.

1. Check the temperature of the water feeding into the booster tank. It must be 110^ to 140^ F ( 43^ to 60^ C) depending on the heating capability of the unit. The inlet water supply must be in sufficient quantity to hold its temperature throughout the dishwashing operation.
2. If incoming water exceeds 20 psi (138 kPa), a pressure reducing valve must be installed.

3. If the wash tank of the dishwasher is filled through the booster heater, this will use up all of the 180°F (82°C) water in storage. Sufficient time must be allowed to reheat the water in storage before starting the dishwasher.

4. Booster heater voltage must be correct for voltage available. Check nameplate on the booster heater for full information.

5. Water pressure at the inlet to the booster heater must be adequate for proper operation of the rinse cycle of the dishwasher, not to exceed 20 psi (138 kPa). Check with dishwasher manufacture for specific details.
6. The breakers or fuses MUST be properly sized.
7. Be sure that the temperature/pressure relief valve is one supplied by Hatco and properly installed.
8. A check valve should not be installed ahead of the booster.

NOTE: If a check valve is installed and cannot be removed install a back pressure relief valve, Hatco part number 03.02.039.00, set at 125 psi (862 kPa) on the incoming line between the pressure reducing valve and the inlet to the booster heater. Discharge must be to open site drain. (See Figure 13.)

1. Primary water heater temperature should not exceed 160^ F ( 71^ C).

WARNING

To avoid any injury or damage, the booster heater must only be serviced by qualified personnel.
