Components
Supplied With Unit
Temperature/Pressure Relief Valve
Blended Phosphate Water Treatment
System
Pressure Reducing Valve
Temperature/Pressure Gauge (2)
Shock Absorber
3/4" Plug (installed)
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
Water Heater water lines.
Use only copper plumbing material. Non-copper plumbing
material may create an unsafe condition.
Do not connect Booster Water Heater directly to a boiler or
furnace coil or any other uncontrolled temperature source.
The Booster Water Heater thermostat could be damaged
causing unit to overheat.
NOTE: If a check valve or water backflow protector is installed
and cannot be removed install a back pressure relief
valve, Hatco 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 Water Heater.
Discharge must be to open site drain.
Pressure And Temperature Relief Valves
For protection against excessive pressures and temperatures
in the Booster Water Heater, install temperature and pressure
protective equipment by local codes. Hatco supplies valves
constructed with brass working parts and heat resistant silicone
seat discs for all Booster Water Heater models.
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, CSA AN SI Z21.22 /CSA 4.4. The temperature/
pressure relief valve must be marked with a minimum
set pressure not to exceed the marked hydrostatic test
pressure of the Booster Water Heater as noted on the unit
specifications.

Back Pressure Relief Valve
CAUTION
Optional With Unit
FOR INSTALLING PRESSURE AND TEMPERATURE
RELIEF VALVES IN ACCORDANCE WITH CSA ANSI
Z21.22/CSA 4.4. 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.
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. Damages caused by the use of these valves on
unit will not be covered by warranty.
