Important Safety Information - Hatco Imperial S Series Installation And Operating Manual

English
Read the following important safety information before using this equipment to avoid
serious injury or death and to avoid damage to equipment or property
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.
Form No. EBOOSTERm-0613

IMPORTANT SAFETy INFORMATION

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.
