Liquid leaks - ERD 500 - ERS 500e - ERS 500 Carbonate - DRS 600 - Liquid leaks - ERD 500 - ERS 500e - ERS 500 Carbonate - DRS 600

Procedure

1. If there is leakage from the side seam of the Dionex DRS 600, Dionex ERS 500e or Dionex AERS 500 Carbonate, check for leakage from one of the four ports of the Dionex ERS 500 into the housing and check the back pressure after the suppressor.
2. If there is liquid coming out of any of the four ports of the Dionex DRS 600, Dionex ERS 500e, or Dionex AERS 500 Carbonate, carefully tighten the fittings in the leaking port – the fittings do not need to be more than ¼-turn past finger tight. If tightening the fittings does not stop the leak, replace the ferrules and bolts on the tubing.
3. If the system backpressure is greater than 450 psi, the leaks are likely caused by excessive back pressure downstream from the suppressor. Find and eliminate the source of the pressure. The suppressor will usually recover from momentary overpressure conditions if allowed to stand approximately 20 minutes with the membranes fully hydrated. SeeStart-up.
4. If the suppressor continues to leak when operated within the proper back pressure range, it must be replaced.
