3. EAKAGE OR HIGHER PRESSURE OPERATION A single pressure adjusting nut at the handle end of the valve is used for pressure adjustment If you need operation up to a higher pressure or if there is a leak between the stator and stator ring remove the handle set screws This gives access to the pressure adjusting nut Using a wrench tighten the adjusting nut about 1 20th turn Use the red dot and punch mark as guides Column A Sample Injector Detector Column B Position A Sample Injector If there is still leakage at this new setting repeat the process Finish by retightening the handle set screw into the hole on the shaft Replace the rotor seal and stator face assembly if the leak continues Note When the valve is not panel mounted the pressure adjusting nut can be hard to turn In this case loosen the three stator screws a 1 4 turn before adjusting the nut Retighten the stator screws before testing for leaks Note Model 9010 Injector only Vent Line 6 should be the same horizontal level as the luer tube to avoid siphoning A siphoning leak will stop when the vent line and sample loop are empty A leak due to a damaged rotor seal will continue Column A Detector Column B Position B Fig 5 Two column selection using Model 3000 3000 038 or 9010 without the loop Page 2 of 4 2320662B 10 08 Rheodyne LLC e A Unit of IDEX Corporation e 600 Park Court e Rohnert Park CA 94928 707 588 2000
