This section introduces the hazards and safety precautions
associated with installing, inspecting, maintaining, or servicing
this product. Before performing any task on this product, read
this safety information and the applicable sections in this
manual, where additional hazards and safety precautions for
your task will be found. Fire, explosion, electrical shock, or
pressure release could occur and cause death or serious injury,
if these safe service procedures are not followed.
Preliminary Precautions
You are working in a potentially dangerous environment of
flammable fuels, vapors, and high voltage or pressures. Only
trained or authorized individuals knowledgeable in the related
procedures should install, inspect, maintain, or service this
equipment
.
Emergency Total Electrical Shut-Off
The first and most important information you must know is how
to stop all fuel flow to the pump/dispenser and island. Locate
the switch or circuit breakers that shut off all power to all fueling
equipment, dispensing devices, and Submerged Turbine
Pumps (STPs).
The EMERGENCY STOP, ALL STOP, and
PUMP STOP buttons at the cashier
’
s station
WILL NOT shut off electrical power to the
pump/dispenser. This means that even if you
activate these stops, fuel may continue to flow
uncontrolled.
You must use the TOTAL ELECTRICAL
SHUT-OFF in the case of an emergency and not
the console
’
s ALL STOP and PUMP STOP or
similar keys.
