WARNING

ELECTRIC SHOCK HAZARD:

• Unit must be installed by qualified, trained installers. Installation must conform to all local electrical and plumbing codes. Installation by unqualified personnel will void the unit warranty and may lead to electric shock or burn, as well as damage to unit and/or its surroundings. Check with local plumbing and electrical inspectors for proper procedures and codes.
• Turn OFF power at fused disconnect switch/circuit breaker and allow unit to cool before performing any cleaning, adjustments, or maintenance.
• Consult a licensed electrical contractor for proper electrical installation conforming to local electrical codes and the National Electrical Code (N.E.C.).
• Unit is not weatherproof. Locate unit indoors where ambient air temperature is a minimum of 70^ (21°C).
• Do not place aftermarket covers on or over booster heater. Doing so can cause temperature and moisture build-up resulting in premature failure and electrical shock.
• This unit must be serviced by qualified personnel only. Service by unqualified personnel may lead to electric shock or burn.
• Use only Genuine Hatco Replacement Parts when service is required. Failure to use Genuine Hatco Replacement Parts will void all warranties and may subject operators of the equipment to hazardous electrical voltage, resulting in electrical shock or burn. 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.

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

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.

EXPLOSION HAZARD: Do not store or use gasoline or other flammable vapors or liquids in the vicinity of this or any other appliance.

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 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, 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' (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. 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.

Use only 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.

Units are equipped with a high temperature limit safety switch that will shut off the power if the unit overheats. Contact an Authorized Hatco Service Agent if the high temperature limit safety switch cannot be reset or continues to trip.

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.

Do not connect booster water heaters to domestic (consumer) dish machines or other domestic utilized equipment. This booster may damage domestic equipment.

Read the following important safety information before using this equipment to avoid serious injury or death and to avoid damage to equipment or property.

WARNING

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

Install booster water heater as close as possible to a commercial dish machine. Employ re-circulation if distance between water heater and dish machine exceeds National Sanitation Foundation (NSF) specifications of five (5) linear feet (1524 mm).

Follow standard welding safety and operational procedures when attaching sliderails to bottom of dishtable.

Make sure the dishtable is strong enough to support the weight of the heater AND water when installing with slide mounting brackets.

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.

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.

This unit has no "user-serviceable" parts. If service is required on this unit, contact an Authorized Hatco Service Agent or contact the Hatco Service Department at 800-558-0607 or 414-671-6350; fax [phone]; or International fax [phone].

CAUTION

BURN HAZARD:

• Water in unit is very hot. Wear protective gloves and proper attire when operating to avoid injury.
- 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 anti-siphon valves on incoming water line.

Check valves on incoming water line is not recommended. Damages caused by the use of check valves on unit will not be covered by warranty.

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

Do not connect an expansion tank of any type to booster heater water lines.

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.

If water supply pressure to the booster inlet is over 20 psi (138 kPa) during flow, install pressure reducing valve with 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.

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

NOTICE

Always drain booster heater with power to the unit off or element burnout could occur.

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 outlet water connection on all Large Compact Series units (C-24 to C-57).

Do not turn or adjust inlet water connection on Compact Series Booster Heaters or internal water flow will change.

Do not back out or loosen any pipe fittings or leaks may occur.

Do not lay unit on the side with the control panel. 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 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.

Units are voltage-specific. Refer to specification label for electrical requirements before beginning installation. Connecting unit to incorrect power supply will void product warranty and may damage unit.

Plumbing Installation

WARNING

Do not connect booster water heaters to domestic (consumer) dish machines or other domestic utilized equipment. This booster may damage domestic equipment.

Do not connect an expansion tank of any type to booster heater water lines.

Use only 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.

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 booster heater directly to a boiler or furnace coil or any other uncontrolled temperature source. The booster heater thermostat could be damaged causing 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 water connection on Compact Series Booster Heaters. Doing so will change the internal water flow.

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. 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 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 30^ F (-1°C) temperature differential must be maintained between the outlet of the first booster heater and the inlet of the second 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 hot water supply line from a normal water heater.

- Water temperature from the water heater should be 110°–140°F (43°–60°C) and should not exceed 160°F (71°C). Minimum temperature differential between inlet and outlet should never be less than 30°F (-1°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.

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

2. 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.

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 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.

Line drawing of a pressure gauge with a central shaft and dial (no text or symbols)

Temperature/Pressure Gauge

1. 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 directional arrow. Valve will reduce pressure only during flow conditions.

CAUTION

If water supply pressure to the booster inlet is over 20 psi (138 kPa) during flow, install standard pressure reducing valve with 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 optional brass pressure reducing valve with built-in bypass (Hatco P/N 03.02.015.00) also available.

Pressure Reducing Valve

1. Install the temperature/pressure relief valve.

• Mini-Compact Series: P/N 03.02.020.00
- Compact and Imperial Series: P/N 03.02.022.00

Temperature/Pressure Relief Valve

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, 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' (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. 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

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 incoming water line.

2. Connect the booster heater water outlet to the commercial dish machine sanitizing rinse pipe connection using a 3/4" union and piping.

NOTICE

DO NOT turn or adjust water outlet connection on Large Compact Series units (C-24 to C-57).

NOTE: Red mark on water outlet 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^) .

NOTE: Some dish machines require two booster heaters to be plumbed in series (not parallel) to meet the demand. To ensure proper operation, a 30^ F (-1°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 (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.

CAUTION

DO NOT turn on power to the booster heater until 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.

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 110° to 140°F (43° to 60°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 160°F (71°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 manufacture 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.

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.

Symptom Probable	Cause Corrective Action
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.

WARNING

This unit must be serviced by qualified personnel only. Service by unqualified personnel may lead to electric shock or burn.

	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.
Relief valve dribbles. No pressure	reducing valve installed or incorrect valve installed causing pressure build-up inside booster tank.	A pressure reducing valve with 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).
