b.
If a mechanical inverter is not available, a
makeshift inverter can be made using sand
bags or any available tools. The cylinder
should be inverted with its top resting on
one sand bag and the bottom end resting
on pile of two or three sandbags.
c.
A Snap-on standard high-pressure hose
(optional; available from GrainPro) should
be connected between the cylinder and the
gas inlet valve.
NOTES:
The hose should withstand a pressure of
88 atmospheres (1,300 psi or 92
kg/cm
2
).
Ensure that all connections are done properly and gaskets are installed as required.
The high-pressure hose should have a length of about 2 meters to facilitate easy connection to the
inlet valve.
d.
Open the outlet port located at the back
(top) of the Cocoon Cargo to displace air
during purging.
e.
Open the gas inlet valve connected to the
inlet port and then open the cylinder tap.
NOTES:
During purging, the liquid CO
2
enters the
liner and evaporates. This pushes the air
upward starting from the bottom.
Following a piston effect, the air is
displaced through the outlet port.
5.9.3.
Safety warning
Caution: CO
2
, although not poisonous, is an
asphyxiant and displaces oxygen. Use either
large vented room or duct attached to outlet
port venting to outdoor.
5.9.4.
Ice formation along the pressurized hose
during CO
2
flushing
a.
During this procedure, some ice may form
around the gas inlet and high pressure
hose.
b.
If this happens do not touch the PVC liner
because it becomes brittle, loses its
flexibility and may crack!
