Delivery
start
Before
the
delivery
starts,
the
dispenser
attendant
checks
whether
the
storage
tank
in
a
vehicle
has
a
homologation
mark,
the
vehicle
engine
and
all
electrical
devices
are
turned
off.
Then
he/she
visually
inspects
the
condition
or
wear
of
the
filling
neck/connector
that
could
be
the
reason
for
leaks.
If
he/she
finds
serious
deficiencies,
he/she
is
entitled
to
refuse
storage
tank
filling.
In
case
of
gas
leak
or
danger
the
attendant
shall
finish
the
delivery.
The
operation
of
the
dispenser
itself
is
ensured
by
the
employee
of
the
fuel
station
who
lifts
the
delivery
nozzle
from
the
dispenser
and
connects
it
to
the
storage
tank
of
the
vehicle
which
must
be
secured
against
moving.
Immediately
after
the
nozzle
is
lifted
the
display
test
is
performed
–
displaying
all
segments
–
and
then
it
is
reset
and
the
product
unit
price
is
displayed.
After
pressing
the
START
button
located
on
the
counter
case
the
electromagnetic
valve
opens
at
the
inlet
of
the
first
pressure
section
and
the
pressure
storage
tank
of
the
vehicle
is
filled
with
compressed
natural
gas.
In
the
moment
when
the
delivery
speed
decreases
under
the
defined
limit,
the
electronic
counter
automatically
switches
delivery
to
the
second
section
and
then
potentially
to
the
third
pressure
section
–
depending
on
the
dispenser
and
fuel
station
configuration.

dispensers,
especially
non
‐
public
‐
company
dispensers,

is
performed
after
pressing
the
