II. Fill Orca CO
2
from Bulk Tank Pump
1. Remove hoses from storage tubes, set in place and open
cabinet doors.
2. Connect supply tank vapor balance hose to Vapor
Balance (DC-5) connection and connect ll hose from
supply tank to Fill Line (DC-1) connection.
3. Open supply tank vapor balance and dispense valves.
a. This assumes supply tank is at a lower pressure than
Orca CO
2
. If Orca CO
2
is at a higher pressure, swap
Orca CO
2
and supply tank in steps 3 and 4.
4. Open and close Vapor Balance Line Drain (V-45) and
Fill Line Drain (V-9) valve to purge air from hoses.
5. Slowly open Vapor Balance (V-44) valve to equalize
pressure in tanks.
6. Open Bottom Fill (V-17) and Pump Inlet/Fill (V-1)
valve.
7. Start supply tank pump lling and monitor liquid level.
8. When liquid level is getting close to full (3/4 of net
capacity), open Vapor Balance Line Drain (V-45) valve.
a. The vapor balance line serves as the 95% full trycock.
9. When liquid exits the Vapor Balance Line Drain (V-45),
valve stop the pump and close the Bottom Fill (V-17)
valve.
10. Close the Vapor Balance Line Drain (V-45), Pump
Inlet/Fill (V-1), and Vapor Balance (V-44), supply tank
dispense & vapor balance valves.
11. Open and close the Fill Line Drain (V-9) and Vapor
Balance Line Drain (V-45) valves to drain and release
all pressure.
Warning! Fast depressurization of liquid
CO
2
can cause dry ice to
form, holding in pressure that
quickly releases when the dry
ice melts. Follow proper safety
procedures for draining and
venting liquid CO
2
from hoses.
12. Disconnect hoses from Vapor Balance (DC-5) and Line
(DC-1) connections.
13. Close cabinet doors and stow hoses. Replace all dust
caps.
III. Fill Orca CO
2
from Onboard Pump
1. In order to minimize pump cavitation and surging:
a. The liquid level in the supply tank must be above the
Orca CO
2
pump inlet height. As such, supply tanks
should be limited to vertical tanks or horizontal tanks
located above the Orca CO
2
pump height.
b. Additional subcool in the supply tank will be
benecial.
c. If the Orca CO
2
tank pressure is signicantly lower
than the supply tank, causing the supply-tank pressure
to drop below the saturation of the supply liquid when
vapor balancing, pressure in the supply tank must be
added to subcool the liquid.
2. Start truck and engage PTO, turn on cruise control and
increase engage speed to set point.
a. Engine must be at low idle speed to engage PTO.
Caution! Engage the PTO when not at
low idle speed will damage the
PTO.
b. Engine will go to set speed with one push of the
cruise control speed increase button.
Caution! Supply tank must have a
vapor balance circuit for this
functionality otherwise pump
damage may occur.
3. Remove hoses from storage tubes, set in place and open
cabinet doors.
4. From delivery tank connect vapor balance hose to Vapor
Balance (DC-5) connection and connect ll hose from
delivery tank to Fill Line (DC-1) connection.
5. Slowly open supply tank liquid valve to ll pump supply
hose with liquid.
6. Open Fill Line Drain (V-9) valve until CO
2
snow comes
out and close valve. This purges air and lls the hose
with liquid.
7. Make sure Pump Inlet/Fill (V-1) valve is closed.
8. — If supply tank is higher pressure than Orca CO
2
:
a. Open Bottom Fill (V-17) valve.
b. Start pump with Switch (SW-1).
c. When supply tank pressure comes within 5 psig
of Orca CO
2
tank pressure, open supply tank
