The table below gives the steps of the pre- filling with SF
Step
1 Remove the valve cap (5) of the
filling tool (4).
2 D Open the SF
D Open and close the cock (11) of
the pressure reducer to eliminate
any air inside the tube (12)
(approx. 3 s at low flow- rate).
D Close the SF
3 Connect the tube (12) to the filling
tool (4).
4 Open the SF
and adjust gas output by acting on
the cock (11) of the pressure
reducer (reduced flow rate).
D Close the tap (9) from time to
time to check pressure on the
gauge (13).
D Start filling again until the
required pressure about 0.05 MPa
is reached.
D Close in this order : the tap (9),
then the cock (11).
