3. Open the gas USE valve and adjust the outlet regulator – normally to 90 psig (6.2
bar/621 kPa).
4. Tighten the supply line fittings at the use point.
Schedule delivery before the container contents drop below ¼ full. This will improve
the filling characteristics as well as the gas withdrawal capabilities.
1. Inspect the easycarb™ for proper vent, supply and fill line installation before
attempting to fill the container.
2. Check supply container valves to ensure they are open.
3. Check the pressure and contents of the supply container(s).
4. Extend the fill hose to the fill box.
5. Inspect all connections for cleanliness. Any moisture that is present can freeze
during liquid transfer. Use a clean, dry cloth to wipe connections if necessary.
6. Open liquid ball valve and purge the fill gun vent until liquid appears. After this is
complete shut the liquid ball valve. Next shut the vent ball valve.
7. Connect the fill gun to the fill connector and read the customer tank pressure to
ensure a positive differential.
8. Open the liquid valve on the fill gun to begin the fill. Never leave the Fill Gun
unattended during the fill.
9. When the pressure indicated on the fill gun begins to rise sharply, terminate the
fill.
10. Close the Liquid Fill valve, and disconnect the fill gun from the fill station. Open
the fill gun Vent valve to relieve trapped pressure .
WARNING:
Delivery systems with operating pressures greater than 300 psig (20.7bar/2068
kPa) may over-pressurize the easycarb™ if not used properly. Do not allow the
pressure, as displayed on the fill gun, to exceed 300 PSI during the fill.
For specific maintenance procedures refer to the applicable paragraph that follows,
and to the replacement parts list.
WARNING:
Isolate components and slowly de-pressurize the plumbing to be repaired
before attempting repairs. The sudden release of pressure could cause per-
sonal injury. Observe safety precautions to prevent dangerous accumulation of
gas. Safety devices and liquid level contents gauge cannot be isolated, there-
fore all liquid must be removed and all pressure in vessel must be relieved
before attempting to repair them.
Note:
During first fill the easycarb™
will be warm and pressure may
equalize before tank is full. If
this occurs, shut off liquid on
fill gun and vent pressure in
easycarb™ down to 125 psig
(8.6 bar/862 kPa) through fill
gun. Repeat if necessary. If
you are not sure if the
easycarb™ is full simply
check liquid contents gauge on
the easycarb™ before venting.
MAINTENANCE
CAUTION:
Carbon dioxide may form into
the solid phase (dry ice) if the
pressure over the liquid is
allowed to drop below 70 psig
(4.8 bar/483 kPa). Pressure in
the container must be
maintained above this value to
ensure solid CO
2
will not form
inside the container. Before
performing maintenance, the
contents of the easycarb™
must be transferred to another
container so that pressure can
be released.
