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.

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.

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.

IMPORTANT SAFETY INFORMATION

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

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.

T o 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.

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.

CIRCUIT BREAKER & FUSED DISCONNECT SWITCH SIZES - 36 to 57 kW

Wire size is based on THHN wire for branch circuit protection at .91 derate factor. Circuit breakers and fused
disconnects are to be mounted remote and wired by 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 & 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.

INSTALLATION

WARNING
T o 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 V ALVE 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.

Form No. EBOOSTERM-0406

20

INSTALLATION

CAUTION
To assure proper operation do not use an anti­siphon 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.

INSTALLATION

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.

2. 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.

3. 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.

INSTALLATION

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.

WARNING
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.

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.

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.

2. 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). (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 p art 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.

TROUBLESHOOTING

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.)

9. Primary water heater temperature should not
exceed 160°F (71°C).
