IMPORTANT SAFETY INFORMATION

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°F (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 copper plumbing material. Non-copper plumbing

material may create an unsafe condition.

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.

Form No. EBOOSTERM-0419

IMPORTANT SAFETY INFORMATION

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.

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.

Incoming water temperature should be minimum of 85°F

(29°C). Damage to the heater can occur if water is cooler

than 85°F (29°C).

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 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 or leaks may

occur.

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 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.

Read the following important safety information before using this equipment to avoid serious

injury or death and to avoid damage to equipment or property.

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

dishmachine.

1. Determine the water temperature rise.

a. 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 a high temperature heated water sanitizing application.

2. Follow the appropriate “Water Temperature Rise” column down and locate the Gallons Per Hour (GPH) of the dishmachine’s rinse

cycle (round up to the next size if 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 dishmachine. 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 a 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 dishmachine 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 factory for suitable Booster Heater.

ambient air temperature is a minimum of 70°F (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.

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

distance between 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.

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 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 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 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 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). 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 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.

Form No. EBOOSTERM-0419

English

4. 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 138 kPa

(20 psi) 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 brass pressure reducing valve with built-in

bypass (Hatco P/N 03.02.015.00) also available.

Pressure Reducing Valve

5. 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

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.

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.

Outlet

1. Flush the water supply line to remove any pipe compound

and foreign matter.

2. Connect the booster heater water outlet to the commercial

dish machine sanitizing rinse pipe connection using a 3/4″

union and copper piping.

WARNING

DO NOT turn or adjust water outlet connection on Large

Compact Series units (C-24 to C-57).

NOTE: Red marks on water inlet and 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.

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.

• 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 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.
