FIAT FIORINO/QUBO NATURAL POWER3) Excess flow,intervenes if the pipes
break and limits the flow of methane ex-
iting to non dangerous levels.
The flow restrictor valve is located to al-
low it to operate even if the solenoid valve
casing is broken due to an impact.
4) Manual tap,it is located upstream of
the solenoid valve.
SOLENOID
VALVES/SAFETY
DEVICES
The solenoid valves Fig. 5and Fig. 6are
bolted directly onto the methane cylinders
with the main function of interrupting the
flow of methane to the supply circuit.
The solenoid valves are open when:
❒the switching button is in the methane
position;
❒the pressure in the cylinder is sufficient
for operation;
❒the engine is running.
The solenoid valve assembly is equipped
with the following safety devices:
1) Fuse pad,in the case of overheating
(temperature above 110 °C), it totally
eliminates the danger of excess pressure
making the methane in the cylinder flow
out as quickly as possible in a controlled
manner.
2) Mechanical excess pressure device
(Burt Disk),in the case of excess pres-
sure (above 330 bar), it ensures that the
methane escapes as quickly as possible in
a controlled manner.It separates the cylinder from the methane
system to allow maintenance operations.
The taps are accessible from outside the
vehicle and are located, in the case of the
lengthwise middle cylinder, at the rear of
the cylinder and, in the case of the trans-
verse rear cylinder, towards the wheel
right side.
To close the taps D-Fig.7: turn the knob
in the direction (1) shown by the arrow
(clockwise
OFF).
To open the taps D-Fig.7: turn the knob
in the direction (2) shown by the arrow
(anticlockwise
ON).
5) Check valve,this prevents the
methane from flowing back to the filler.

CHECKING LEVELS
Fig. 20
Never smoke while
working in the engine
compartment: flammable gases
and vapours may be present,
constituting a fire risk.
IMPORTANT
When topping up, take
care not to confuse the
various types of fluids:
they are not interchangeable and
could seriously damage the car.
1. Engine coolant
2. Battery
3. Windscreen washer fluid
4. Brake fluid
5. Engine oil
6. Power steering fluid
