CombiFlash Torrent Solvent Tanks Instruction Sheet - Isco

CombiFlash Torrent ®Solvent TanksInstruction SheetInstruction Sheet 60-5243-188November 30, 2010Pressurized solvent tanks are a convenient way tomanage solvents for purification runs on the CombiFlashTorrent. Solvent tanks contain vapors yet still supportsolvent level sensing. These instructions apply to the20-, 40- and 60-liter size tanks.InstallationNoteThe CombiFlash Torrent power should be OFF whilecompleting the electrical, air, and solvent connections.Electrical ConnectionsThe CombiFlash Torrent system controls an air solenoid/regulatormodule. This module supplies ~3 psi tankpressure when the system is on.To connect the solenoid, attach the solenoid moduleto the connector labeled Fraction Valve on the rearpanel of the CombiFlash Torrent. Position the solenoidmodule in an accessible location where you can laterconnect the air supply.Air and Solvent ConnectionsNoteThe tanks are labeled “Tank A” for A solvent and“Tank B” for B solvent. Note that Tank A has twovalves.Refer to Figure 1 for the following instructions.1. Connect the A Solvent Line from the Torrent’s AInlet to the Solvent Quick Connect on Tank A.Repeat for the B Solvent Line.2. Connect the A Level Sense Line from the Torrent’sA Level port to the Union on Tank A.Repeat for the B Level Sense Line.3. Connect the Reference Pressure line from theTorrent’s “Press Ref” port to the side of the crossfitting on Tank B.4. Connect the 1 /4-inch tubing between the cross fittingson the Tank A and Tank B.OPTIONALPRESS REF (

Instruction Sheet 60-5243-188 November 30, 20105. Connect the tubing between the Solenoid/regulatormodule and the top connection on the MainPressure Valve (Tank A).6. Connect the pressurized air or gas supply to theinlet on the Solenoid/regulator Module. The supplyshould be dry and regulated to 15–150 psi.7. Locate the 1 /8-inch plug (209-0165-21) in the CombiFlashTorrent Accessory Kit (60-5249-002).Attach this plug to the B Prime port on the Torrent.8. Ensure that the A and B Solvent Shut-off valvesare open (in-line).System Configuration SettingsThe system configuration settings must be modifiedto disable the B Prime Pump. To do so:1. Place the front panel power switch in the ONposition.2. When the main PeakTrak ® window is displayed,select the Tools>Configuration menu command.3. On the Instrument Configuration tab, deselectthe “Enable solvent B priming pump” option.4. Click OK to save the new configuration setting.The CombiFlash Torrent is ready for operationOperationBefore operating the CombiFlash Torrent with pressurizedtanks, first verify the following:● the Air or Gas supply is on● the Main Pressure Valve points up● the A and B Solvent Shut-off valves are open(in-line)● the pressure gauge on each tank reads about 3psi.The system is ready when the above conditions aremet. The tanks should be filled with solvent before arun, and re-filled if the CombiFlash Torrent detects thata tank solvent level is low.Filling the TanksTo fill a tank:NoteThe tank pressure must be at 0 psi before opening thetank or disconnecting any air or solvent fitting.1. Observe the pressure gauge on the tank. If thetank is pressurized, turn the Main Pressure Valvedown to relieve the pressure in both tanks.2. When the gauge indicates 0 psi, lift the bail(latch) to loosen the cap. Rotate the cap andremove it from the tank.3. Fill the tank. Leave at least 5 cm (2 inches) ofhead space.4. Replace the cap and latch the bail.5. Repeat steps 2 through 4 to fill the other solventtank.6. Turn the Main Pressure Valve up to pressurizethe tank. Note that the CombiFlash Torrent mustbe powered on to actuate the Solenoid/regulatormodule and pressurize the tanks.Replacing TanksIf additional tanks are on hand to quickly replenishthe solvent during a run, swap the tanks using theinstructions below:NoteThe tank pressure must be at 0 psi before opening thetank or disconnecting any air or solvent fitting.1. Observe the pressure gauge on the tank. If thetank is pressurized, turn the Main Pressure Valvedown to relieve the pressure in both tanks.2. Close the Solvent Shut-off valve on the tank.3. Obtain a container that will hold the volume ofsolvent in the inlet line.4. When the gauge indicates 0 psi, disconnect theSolvent Quick Connect fitting on the tank. Drainthe inlet line into the container.5. Disconnect the air lines from the tank.6. Swap the tank with a full one.7. Reconnect the air lines and solvent line.8. Open the Solvent Shut-off valve.Repeat steps 2 through 8 to replace the othertank if necessary.9. Turn the Main Pressure Valve up to pressurizethe tank.Assistance AvailableShould you require assistance with these instructions,contact your Teledyne Isco representative or thefactory.Last modified November 30, 2010Teledyne Isco, Inc.P.O.
