6.1.2 Cascade Filling From Storage
Cascade filling procedure will allow the user
to fill more bottles from the system storage
banks before he must rely on the fill rate of
the compressor. This example is written for
a four bank storage system and assumes
that all four banks are full.
Begin the filling procedure from section 6.1.
Never open both To Bank and From Bank
valves(see section 4.3 #1 & #2) of the
same bank while refilling a bank and
cascading off of another bank.
As Banks are depleted (less than 1000psi.)
they should be removed from the cascade
rotation. (i.e. when Bank #1 drops below
1000psi. start the next filling cycle with
Bank #2)
As Banks are removed from the cascade
rotation they can be refilled one at a time
by turning on the compressor and opening
the correct To Bank valve(see section 4.3
#1) while more bottles are being filled with
the air already in storage.
1. - Make sure all valves on fill panel and in
containment drawer are closed.
2. - Check that the visual inspections and
hydro test of the bottle to be filled are
current. Check the bottle to be filled for it’s
correct pressure rating.
3. - Open From Bank #1 valve.(see section
4.3 #3) The inlet pressure gauge(see
section 4.3 #4) will immediately read the
same pressure as the bank #1 pressure
gauge.(see section 4.3 #2)
4. - Check that the regulator outlet pressure
(see section 4.3 #8) matches the pressure
rating of the bottle.
All bottles being filled together must have
the same pressure rating and filled at the
lowest recommended fill rate.

Danger!
5. - Open fill station containment shield box
drawer.(see section 4.2 #4)
6. - Load customer supplied bottles into the
bottle cells(see section 4.2 #3) and connect
fill hoses.
7. - Open valves on customer supplied
bottles and fill hose valves that are being
used.
For any fill hoses that are not being used
the fill hose valve must be closed.
8. - Close fill station containment shield box
drawer.(see section 4.2 #4)
9. - Open fill valve in accordance with bottle
manufacturer's instructions. Typically filling
is a slow process.
10. - Close fill valve(see section 4.3 #11)
when bottle pressure(see section 4.3 #10)
and regulator outlet pressure(see section
4.3 #8) equalize at desired pressure and
continue to step #11.
or
If pressures equalize and desired pressure
is not obtained continue to step#19
11. - Open fill station containment shield
box drawer.(see section 4.2 #4)
12. - Close valves on customer supplied
bottles and fill hose valves.
13. - Open bleed valves on any air hoses in
use.
14. - Disconnect fill hoses from bottles.
15. - Remove bottles.
16. - Close all bleed valves.
17. - Repeat process beginning at Steps 1
until all bottles are filled.
18. - Continue to step #40
19. - Close “From Bank #1” valve.(see
section 4.3 #3)
20. - Open “From Bank #2” valve.(see
section 4.3 #3)
