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 hightemperature 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.
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.

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 800-690-2966; or

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.
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.
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.

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.

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.
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.
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.
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.

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
WARNING
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.
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.
