Fuel Dispensers TATSUNO EUROPE ‐ Installation and User Manual , revision 10, January 2022
5.3.2. LPG DELIVERY
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 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.
LPG delivery into motor vehicles with attendants
The operation of the dispenser 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. After
pressing the control button (START button) located on the counter case, the reset of the electronic counter is
performed and the pump electric motor located at the storage tank starts. Delivery can be terminated at any
time by releasing the control button. When refilling the "full" tank, after reaching the 80% fill level the tank filler
neck is closed and the safety control (electronic counter) terminates the delivery within 10 seconds regardless
of the control button. Delivery data remains recorded on the counter display. Dispensers equipped with an
electronic pre‐selection allow pre‐selection of the exact quantity required which is determined by volume or
amount. These stands are equipped with a two‐stage solenoid valve.
NOTICE
Pursuant to EN 14678‐1:2013, article 4.5.8, LPG dispensers designed for self‐service operation must be
equipped with a "dead man button" (START button) to ensure that the delivery process can only be started and
maintained by pressing this button. Release of this button shall immediately stop the flow of LPG.
NOTE
According to EN 14678‐1:2013, article 4.5.1.1, LPG dispensers must be equipped with a breakaway or
shear coupling located between the delivery nozzle and the dispenser. This breakaway coupling disconnects the
flow rate at both ends in case of emergency. LPG dispensers are standardly equipped with a breakaway coupling
which breaks if a force greater than 200N and less than 500N is applied to it.
