SPECIFICATIONS

Booster Heater Sizing Chart
Use the table below or the “Booster Heater Sizing Formula” to determine what Booster Heater kW rating is needed with your dish machine.

1. Determine the water temperature rise.

   • Subtract the lowest incoming water temperature supplied to the Booster Heater from the desired output water temperature of the Booster Heater. The difference is the Water Temperature Rise. Typically 145°F (63°C) is a low-temperature chemical sanitizing application and 185°F (85°C) is high-temperature heated water sanitizing application.

2. Follow the appropriate “Water Temperature Rise” column down and locate the Gallons Per Hour (GPH) of the dish machine’s rinse cycle (round up to the next size if the exact GPH isn’t listed).
   NOTE: The primary water heater must be able to supply the Booster Heater with the incoming water temperature at the GPH usage of the dish machine. Failure of the primary water heater to supply a continuous temperature will result in an inadequate output temperature of the Booster Heater.

3. Follow the GPH row to either of the “Booster Heater kW” columns for the appropriate Booster Heater kW rating.
   Example: An incoming water temperature of 115°F (46°C) with the desired output temperature of 185°F (85°C) would be a 70°F (39°C) water temperature rise. A 70°F (39°C) water temperature rise with a dish machine capable of 185 GPH usage will require a minimum of a 36 kW Booster Heater.

NOTE: When incoming water temperatures are less than 85°F (29°C), consult the factory for a suitable Booster Heater.

Wire size is based on THHN insulated, copper wire for branch circuit protection at 0.91 derate factor. Circuit breakers and fused disconnects are to be mounted remotely and wired by the contractor. Sizes are based on the 2002 NEC table 310-16. Conduit size based on conductors plus ground wire sizing per Table C1 from Appendix C. Only 6, 7, and 9 kW models can be field converted to single or three phases (open delta on 3 phase). Check the wiring diagram supplied with the unit when converting the phase of the unit. A larger branch circuit is required than for a balanced 3 phase of equal kW. Balanced 3 phase available, consult factory.

EXPLOSION HAZARD: Do not store or use gasoline or other flammable vapors or liquids in the vicinity of this or any other appliance.
Install booster water heater as close as possible to a commercial dish machine. Employ re-circulation if the distance between the water heater and dish machine exceeds National Sanitation Foundation (NSF) specifications of five (5) linear feet (1524 mm).
Install booster water heater in a horizontal position with the base parallel to the floor and the inlet connection at the lowest point. Improper installation could create an unsafe condition.

1. Remove the unit from the box.
   NOTE: To prevent delay in obtaining warranty coverage, complete online warranty registration. See the IMPORTANT OWNER INFORMATION section for details.

2. Remove tape and protective packaging from all surfaces of unit.

3. If unit is equipped with legs, carefully lay unit on its side and install the four legs. NOTICE
   Do not lay the unit on the side with the control panel or inlet and outlet pipes. Damage to the unit could occur.
   NOTE: If the unit is not level, use an adjustable wrench to adjust the foot of each leg until unit is level. Each leg is adjustable from 6″ (152 mm) to 7″ (178 mm).

4. Place the unit in the appropriate location.

   • The location must have a solid foundation along with being clean and dry.
   • Adequate front clearance is required to allow for accessibility to the control compartment. Hatco recommends the side clearance be at least 2″ (51 mm).
   • The location must have adequate clearance to allow for inspection, testing or replacement of pressure and/or temperature relief valve.
   • Install the booster heater as close as possible to the commercial dish machine for efficient operation.
     WARNING
     Make sure the dishtable is strong enough to support the weight of the booster heater and water when installing with slide mounting brackets.
     Follow standard welding safety and operational procedures when attaching slide rails to the bottom of dishtable.

5. Install unit under dishtable using mounting slide brackets, if applicable (Compact Series only).

   • Weld slide rails to the bottom of the dishtable.
   • Using Hatco slide brackets as a template, drill 1/8″(3 mm) holes into the sides of the heater jacket.
   • Attach slide brackets to the sides of the heater with supplied screws.
   • Slide heater onto slide rails under dishtable.

Plumbing Installation

WARNING

• Do not connect booster water heaters to domestic (consumer) dish machines or other domestically utilized equipment. This booster may damage domestic equipment.
• Use only copper plumbing material. Non-copper plumbing material may create an unsafe condition.
• Refer to the BOOSTER HEATER SIZING CHART in this manual to ensure proper sizing and avoid personal injury and/or damage to the booster heater.

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

NOTICE

• Use dielectric couplings when connecting dissimilar metals, such as galvanized to copper. This will prevent electrolysis or premature plumbing damage.
• Do not turn or adjust inlet or outlet water connection on Compact Series Booster Heaters or internal water flow will change and the unit will not produce a consistent outlet temperature.
• Do not back out or loosen any pipe fittings. Doing so may cause leaks.
• Do not lay unit on the side with the control panel or inlet and outlet pipes. Damage to the unit could occur.
• Incoming water in excess of 3 grains of hardness per gallon (GPG) (0.75 grains of hardness per liter [GPL]) must be treated and softened before being supplied to booster heater(s). Water containing over 3 GPG (0.75 GPL) will decrease efficiency, increase energy use, and reduce the operating life of the unit through the increased lime build-up. Product failure caused by liming or sediment buildup is not covered under warranty.
• Do not use deionized water. Deionized water will shorten the life of water reservoir and heating element.
• NOTE : Product failure caused by liming or sediment buildup is not covered under warranty.
• NOTE : A 3/4″ union and a drain valve are required for easy servicing.
• NOTE : An optional flow restrictor (P/N 03.02.074.00) is available for installation on the water inlet line.
  NOTE : Some dish machines require two booster heaters to be plumbed in series (not parallel) to meet the demand. To ensure proper operation, a 29°F (16°C) temperature differential must be maintained between the inlet and outlet of each booster heater.

Inlet
Use the following procedure to install the inlet assembly. Refer to the appropriate “Plumbing Connections” diagram in this section for more information.

1. Connect the booster water inlet to a copper hot water supply line from a normal water heater.

   • Water temperature from the water heater should be 115°–145°F (46°–63°C) and should not exceed 155°F (68°C). The minimum temperature differential between inlet and outlet should never be less than 29°F (16°C).
     NOTE: Refer to BOOSTER HEATER SIZING CHART for application information.
     NOTE: The red mark on the inlet and outlet water pipes of Compact series units must remain in the top most position.

2. Install a shut-off valve (a full opening gate or ball type).

3. Install one of the temperature/pressure gauges.

   • When installing the temperature/pressure gauge, the temperature sensing element must be in the water stream and the gauge must be mounted upright (see illustration below).

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

CAUTION
Hatco requires that two temperature/pressure gauges (Hatco P/N 03.01.003.00) be installed to ensure 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 or backflow prevention is installed and cannot be removed, install a back pressure relief valve (P/N 03.02.039.00) preset at 125 psi (862 kPa) on the incoming line between the pressure reducing valve and the inlet to the booster heater. Any discharge must be directed to an open site drain.
• If the back pressure relief valve is not acceptable, a high-temperature thermal expansion tank may be substituted. The thermal expansion tank must be installed on the inlet side of the booster. The appropriate size and rating of the thermal expansion tank must be determined by qualified personnel, assuming a minimum 212°F (100°C) thermal, and 150 psi (1034 kPa) rating to match the built-in safety devices on the booster.
• Install the pressure-reducing valve if water pressure available to the booster heater inlet is over 25 psi (172 kPa).
• Set pressure reducing valve at 20 psi (138 kPa) flow pressure.

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

CAUTION
If water supply pressure to the booster inlet is over 138 kPa (20 psi) during flow, install a standard pressure-reducing valve with a built-in bypass (Hatco P/N 03.02.004.00) for proper operation of dish machine rinse nozzles.

• NOTE : The pressure-reducing valve must be the type equipped with a high-pressure bypass, as supplied by Hatco.
• NOTE : Optional brass pressure reducing valve with built-in bypass (Hatco P/N 03.02.015.00) also available.
• Install the temperature/pressure relief valve directly into the marked fitting on the rear or side of the unit.
• Mini-Compact Series: P/N 03.02.020.00
• Compact and Imperial Series: P/N 03.02.022.00

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.

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 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 ambient conditions that are not indicative of stored water temperature. TO AVOID WATER DAMAGE OR SCALDING DUE TO VALVE OPERATION, THE DRAIN PIPE MUST BE CONNECTED TO THE VALVE OUTLET AND RUN TO A SAFE PLACE OF DISPOSAL.

The discharge line must be as short as possible and be the same size as the valve discharge connection throughout its entire length. The 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′ (9.1 m), 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. The 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 the water temperature reaches 210°F (99°C). Read the tag on the valve for additional information.

CAUTION

BURN HAZARD:
Valves supplied by Hatco are designed for high-temperature commercial operation. Do not substitute Hatco valves with valves designed for domestic water heaters. Do not use an anti-siphon or check valves on the incoming water lines.

   DO NOT turn or adjust the water outlet connection on Large Compact Series units (C-24 to C-57).
   NOTE: Red marks on the water inlet and outlet pipe for C-24 to C-57 series units must remain in the topmost position.
   NOTE: Be certain the connection is made to the final rinse and not to the wash tank.

3. 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.

   • The water temperature at the outlet should be 185°–190°F (85°–88°C).

• NOTE : Some dish machines require two booster heaters to be plumbed in series (not parallel) to meet the demand. To ensure proper operation, a 29°F (16°C) temperature differential must be maintained between the inlet and outlet of each booster heater.
• NOTE : Hatco recommends installing an optional shock absorber (P/N 03.04.057.00) in the outlet line as close as possible to the commercial dish machine solenoid rinse valve. The shock absorber softens the water hammer caused by automatic dish machine valves.

Plumbing Installation Inspection

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

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

WARNING

• 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.
• 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.

TROUBLESHOOTING GUIDE

IMPORTANT! Read Before Using the Troubleshooting Guide
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.

WARNING

ELECTRIC SHOCK HAZARD:

• Turn OFF power at fused disconnect switch/circuit breaker and allow unit to cool before performing any cleaning, adjustments, or maintenance.
• This unit must be serviced by qualified personnel only. Service by unqualified personnel may lead to electric shock or burn.

Before proceeding with the “Troubleshooting Guide” to diagnose an issue, check ALL of the following outside factors.

Water Temperature

• Check the temperature of the water feeding into the booster tank. It must be 115° to 145°F (46° to 63°C), depending on the heating capability of the unit. The inlet water supply must be of sufficient quantity to hold its temperature throughout the dishwashing operation.
• If the wash tank of the dish machine 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 dish machine.
• Primary water heater temperature should not exceed 155°F (68°C).

Water Pressure

• Water pressure at the inlet to the booster heater must be adequate for proper operation of the rinse cycle of the dish machine, not to exceed 20 psi (138 kPa). Check with dish machine manufacturer for specific details.
• If incoming water exceeds 20 psi (138 kPa), a pressure-reducing valve must be installed.

Electrical Connections

• Booster heater voltage must be correct for voltage available. Check the specification label on the booster heater for full information.
• The breakers or fuses MUST be properly sized.

Plumbing Connections

• The temperature/pressure relief valve must be properly installed and be supplied by Hatco.
• 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 (P/N 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.

If the unit does not function properly after performing these checks, continue to the “Troubleshooting Guide” in this section.

WARNING

• This unit must be serviced by qualified personnel only. Service by unqualified personnel may lead to electric shock or burn.
• ELECTRIC SHOCK HAZARD: Turn OFF power at fused disconnect switch/circuit breaker and allow unit to cool before performing any cleaning, adjustments, or maintenance.

Water reaches 180°F (82°C) but does not last through the entire dish machine operation.| Low incoming water temperature.| Incoming water temperature must be adequate for booster size. Increase incoming water temperature.
Incoming water temperature drops.| Primary water supply is not adequate to provide correct temperature in sufficient quantities. Increase supply of primary hot water.
Flow pressure is too high.| Higher pressure uses an excessive quantity of hot water. Adjust flow pressure to 20 psi (138 kPa).
Booster heater may be undersized.| Booster heater must be properly sized for incoming water temperature and rinse requirements of the dish machine.
Incorrect voltage.| Check voltage on heater serial plate and make sure supplied voltage matches. A 240V booster heater operating on 208V reduces wattage to 76% efficiency.
The booster heater does not heat at all or only delivers water at 120°- 150°F (49°-66°C).

The error indicator light is illuminated.

| Unit may have been energized without water (dry fired) causing the element(s) to burn out quickly.| Replace the element(s).
Fuses may be blown or circuit breaker tripped.| Check for proper fuse sizing. Replace fuses. Check/reset circuit breaker.
Over-current fuses may be blown.| Check for shorted elements, bad fuse block or short in wiring.
Temperature setting out of calibration or inoperable.| Temperature setting should be maximum of 190°F (88°C).
Contactors do not pull in.| Test for voltage at coils. If coils are open or shorted, replace contactors.
High limit switch may be tripped or defective.| Reset switch, refer to “High Temperature Limit Safety Switch” in the MAINTENANCE section. If switch continues to trip or cannot be reset contact an Authorized Service Agent.
Transformer not working properly.| Check secondary voltage, it should be the same as the control circuit voltage. If not, replace the transformer.
Low water cutoff inoperable, contacts do not close.| Remove probe wire and touch it to the tank. If contacts close, probe is fouled and must be cleaned or replaced.

Relay on circuit board maybe defective. Jumper terminals 6 and 7. If unit energizes, circuit board is defective and should be replaced.

Water at dish machine is not at the proper temperature.| Gauge(s) not working properly.| Check temperature of water with a thermometer to be certain gauges are working correctly. If not, replace gauge(s).
Thermostat set too low.| Adjust or recalibrate, refer to “Thermostat Adjustment” in the MAINTENANCE section. If thermostat will not recalibrate properly, replace it.
Booster heater has more than five (5) linear feet (1524 mm) of water pipe to the dish machine, causing the water to cool off inside the pipe.| If located farther than five  (5)  linear feet (1524 mm), pipes should be wrapped in insulation, and/or a recirculating system installed.
Symptom| Probable Cause| Corrective Action
---|---|---
Relief valve dribbles.| No pressure reducing valve installed or incorrect valve installed causing pressure build-up inside booster tank.| A pressure- reducing valve with a high-pressure bypass must be installed in the incoming water line to allow water to expand back into the feed line.
Bypass in pressure reducing valve may be blocked.| Clean bypass or replace with new valve with built in bypass.
Check valve or anti-siphon valve installed in the feed line.| Remove check valve or anti-siphon valve to allow for water expansion or install a back pressure relief valve (P/N 03.02.039.00) on the incoming water line.
Relief valve opens.| Unit is overheating.| Thermostat may be set too high or is sticking. Recalibrate or replace the thermostat.
Contactor may be sticking in closed position not allowing unit to cycle off.| Replace contactor(s).
High temperature limit safety switch trips.

The error indicator light is illuminated.

| Temperature limit safety switch is defective.| If booster heater is not overheating, replace High Limit Safety Switch.
Thermostat set too high.| Adjust or recalibrate, refer to “Thermostat Adjustment” in the MAINTENANCE section.
Incoming water temperature too high causing nuisance tripping of high temperature limit switch.| Incoming water temperature should not be higher than 160°F (71°C).
Chattering contactor or low water cutoff circuit board| Loose connections or wire connection has insulation under crimp.| Tighten all connections and check crimps
Low voltage.| Check control circuit voltage or secondary voltage with transformer.
Probe may be fouled.| Bypass probe by removing wire from low water cutoff probe and grounding to tank. Clean or replace probe if chattering stops.
Contactor(s) may be bad.| Test contactor coils and replace if needed.
Heating element(s) burn out.| Tank inadvertently drained leaving element(s) in a dry condition.| Replace element(s), and make sure tank is full of water at all times. Check low water cut-off system for proper operation.
Lime buildup in tank causing element(s) to split and burn out.| Replace element(s), and clean or delime tanks periodically. A water softener or blended phosphate treatment system may be required.
