IMPORTANT SAFETY INFORMATION
Form No. EBOOSTERM-0712
3
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 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.
