| Problem | Caused by | Resolution |
| Product flow problems | No or low product flow | No or low inert gas supply | Check the pressure gauges on gas cylinder or source to ensure an adequate supply is available. Replace the gas tank, if needed. |
| Product flow problems | No or low product flow | Gas or solvent supply valves closed | Check to ensure the gas and solvent valves in your system are open. Open the valves, if needed. |
| Product flow problems | No or low product flow | Pressure regulator malfunction | Check both the inlet and outlet pressures on all solvent and gas regulators. Adjust pressure regulator controls. If adequate pressure is seen on inlet side of regulator and outlet pressure does not respond to adjustment, repair or replace regulator. |
| Product flow problems | No or low product flow | Obstruction in solvent lines | Verify the solvent flow at various points throughout your plumbing system. Start with a point closest to the container and work your way toward the dispensing area. This will help you pinpoint the area that is obstructed. Repair or replace and obstructed tubing and/or pipes. |
| Product flow problems | No or low product flow | Malfunctioning Pressure Relief Valve or Rupture Disk Assembly | Check to see if gas is leaking from the PRV or PRDA. If gas is leaking from these areas turn the gas supply off and contact Avantor Technical Service Department for assistance. |
| Product flow problems | Gas, instead of solvent, is discharged from the container dispenser | Empty CYCLE-TAINER container | Check to see if there is any solvent left in the container. If it is empty, replace the empty container with a full container. |
| Product flow problems | Excessive gas bubbles in product supply lines | Outgassing of dissolved gas from the solvent | Pressurize and dispense product from the CYCLE-TAINER containers at the same temperature as the end use. Cool temperatures at a storage and pressurization point promote higher gas solution. This can result in outgassing (bubbles) at a warmer end use location. |
| Incorrect container instrument readings | Volume readings are erratic or display is blank on the Liquid Level Indicator (LLI) cube | Incompatible LLI cube for the container | Check the label on the front of the LLI to see which container type (C or S) the cube is designed for. If the label says S, then a type S container must be used. If the cube is labeled type C, then it should only be used with a type C container. |
| Incorrect container instrument readings | Volume readings are erratic or display is blank on the LLI | Poor plug connection | Check to ensure male and female connectors on the container and LLI signal line are properly mated. Reconnect the cable, if needed, to re-secure the connection. |
| Incorrect container instrument readings | Volume readings are erratic or display is blank on the LLI | Bent pins on the LLI cable | Check to ensure male connectors on the LLI signal line are not bent or broken. If they are bent or broken, please call Avantor Customer Service at 1-800-582-2537 for a replacement. |
| Incorrect container instrument readings | Volume readings are erratic or display is blank on the LLI | Dead batteries | Open the Indicator by unscrewing the four recessed screws on the front panel. Replace the two batteries with 9-volt alkaline batteries. Caution: Do not tamper with or remove electronic chip from its holder. Reattach front panel. |
| Incorrect container instrument readings | Pressure gauge reads zero upon container receipt | Conditions during transit | Container is shipped with a blanket of high purity gas on the solvent. Gas going into solution and temperature fluctuations during transit may cause the gauge to read near zero (0). The solvent integrity will be maintained as long as the container will hold pressure upon use. |
| Incorrect container instrument readings | Pressure gauge reads zero upon applying gas to the container | Various | Refer to "product flow problems" above. |
| Quick-connect problems | Quick-connects will not easily connect or will not connect at all | Vapor lock | Hydroscopic pressure between the valve and the male stem may have built up. Open the valve and let the container sit a few minutes. Then try to reconnect the quick-connects. |
| Container malfunction | Quick-connects or container valves malfunction or leak | Defective or broken part or accessory | Contact Avantor Customer Service to obtain assistance with returning the container for repair. |
| Container malfunction | Container pressure relief valve malfunctioning or leaking | Defective or broken part or accessory | Contact Avantor Customer Service to obtain assistance with returning the container for repair. |
| Container malfunction | Quality seals are broken or missing upon receipt of the container | Defective or broken part or accessory | Contact Avantor Customer Service to obtain assistance with returning the container for repair. |
