Consulting the manual
The GLOBAL VISTA CNG compressed natural gas dispenser is used in areas that are potentially dangerous
and with flammable products.
We recommend scrupulously to follow the precautions and warnings described hereafter. Non-compliance
with the rules listed in this manual could potentially bring serious damages to things or persons.
Warnings and safety
Always follow safety precautions in the CNG area of the fuelling station.
Display the following the signs in clearly visible areas:
NO SMOKING
NO OPEN FLAMES
FLAMMABLE PRODUCTS
TRIPPING HAZARD
PERIODICALLY INSPECT THE PROPER FUNCTIONING OF THE EXTINGUISHERS
RISK OF EXPLOSION
ALWAYS USE PROPER PERSONAL PROTECTION
DISCONNECT ALL ELECTRICAL CONNECTIONS BEFORE WORKING ON THE
DISPENSER
VERIFY PROPER FUNCTIONING OF GROUNDING SYSTEM
The positions of these warnings depend on local conditions but they must be visible from the dispenser.
Ensure that all station attendants know how to behave in an emergency situation
Protection from pressure-related risks
The hydraulic circuit of the dispenser works under pressure.
Before performing any maintenance, accurately close the cut-off valve/s located at the base of the dispenser
and release the internal circuit pressure. Pay particular attention in releasing pressure, as, if not performed
properly, some sections of the hydraulic circuit can remain under pressure due to the presence of check
valves and/or motorized valves. To release the dispenser pressure follow the instructions mentioned later on
in the manual.
Preventing CNG leaks
Take all the necessary measures to prevent any gas leaks.
Breakaway devices
In some countries the use of breakaway devices are obligatory by law. We recommend it nonetheless even in
countries where it is not compulsory, in order to guarantee interruption of gas flow in case of an accidental
pull on the hose.
