•
Switch the control of the pump to "pres-
sure" and, keeping the valve in the ver-
tical axis, check that it is possible to
pressurise the valve up to values
slightly below 1.45PSI(~0.87PSI)
10kPa(~6kPa) 100mbar(~60mbar).
Note: The setting pressure is easily recognisable
in that, when it is reached, the valve discharges
the air emitting a little noise.
•
Position the valve in the horizontal axis
and check that you can pressurise it to
values well above the setting pressure
(eg. 7.25PSI (50 kPa) (0.5bar) without
guaranteeing the maintenance).
If you detect abnormal behaviour, replace the
valve.
Note: Any malfunction of the valve can cause de-
formation of the fuel tank or aggravate the working
conditions of the canister.
