5. Troubleshooting
Ice On Separator
It is normal for the high pressure clamps and flexible metal lines on the top of the separator to form
ice during operation. If ice is forming on the outside of the separator vessels this is an indication that
there is no flow inside the separator cooling jacket. The system should be shut down by pressing the
Recover CO
2
Button on the Manual screen. This will put the system into recovery mode so that the
cooling system can be inspected.
Ensure that the chiller/heater is turned on. Ensure that all blue coolant lines are properly connected.
Ensure that the collection cup coolant lines are properly connected to the first separator. Ensure that
the correct size orifice is being used inside Separator 1. Normal operating pressures within the
separators is between 350-380psi. If pressures are much lower than 250psi, then ice may start to
form on the separators. Also ensure that the temperature of the surrounding environment is no colder
than 65°F, it is possible for the chiller/heater to have difficulty maintaining system temperatures if the
surrounding environment is to cold.
Do not attempt to work on the cooling system while the system is running.
Low Extractor Pressure
If the extractor pressure is unable to meet the target pressure, first verify that the CO
2
cylinder has
sufficient CO2 (bottle gauge above 400 psi). If the bottles have plenty of C02, check to see if the
orifice size is to large (if separator pressure stays above 400 psi this may be an indication). Finally
check to see if the pump outlet is hot (Caution: can be up to 160 F). If pump outlet is cool, the pump
may have lost prime.
Extractor Overpressure
– Orifice Clog, or Orifice is to small
The valveless expansion technology uses a small orifice to regulate pressure. This orifice can
become plugged when foreign material is entered into the plumbing between the extraction vessel
and separator vessel
In the event that separator pressure decreases and/or extractor pressure increases causing an
extractor high pressure fault, it is most likely a clogged orifice or your orifice you are using is too
small. Follow the steps below to clear an orifice clog.
5.1.1
From the Home Screen, Press the Manual Screen Button.
5.1.2
From the Manual Screen, Press the Clear Clogged Orifice Button.
5.1.3
Wait for the system to provide a message popup indicating it is safe to Open Valve
10 and clean the orifice.
5.1.4
Open Valve 10
5.1.5
Verify that both Separator vessel gauges read zero.
5.1.6
Remove the flexible metal lines from the top of the separators. Use two wrenches to
prevent the NPT fittings from loosening in the separator cap.
5.1.7
Remove the yellow wire connected to the Separator #1 thermocouple.
5.1.8
Use the 5/8-in ratchet wrench to remove the high pressure sanitary clamps from the
top of Separator #1.
5.1.9
Remove the cap from the top of Separator #1.
5.1.10
Ensure you are using the correct size orifice and inspect for clogs.
5.1.11
Clean the orifice by soaking it in alcohol and blowing it out with compressed air.
Verify the orifice is clear by looking through it.
5.1.12
An orifice cleaning tool is available on the online store for stubborn clogs.
5.1.13
Reassemble the orifice.
5.1.14
Replace the separator cap and tighten the clamp bolts.
