Dionex ICS-3000 - Rebuilding a High-Pressure (Injection) Valve

9.19 Rebuilding a High-Pressure (Injection) Valve
Dionex recommends rebuilding the injection valve annually. The Injection Valve
Rebuild Kit (P/N 057896, 6-port valve; P/N 061759, 10-port valve) contains all
required replacement parts. This procedure also applies to high-pressure valves
installed in an ICS-3000 Automation Manager.
NOTE Substitution of non-Dionex parts may impair valve
performance and void the product warranty.
NOTE If you prefer, you can replace the high-pressure valve
“pod,” instead of rebuilding the valve. Replacing the
pod is easier and faster than rebuilding the valve.
1. Turn off the pump flow from the Control panel in Chromeleon or Chromeleon
Xpress or press
PUMP FLOW on the front of the pump.
2. Press the
POWER button on the front of the DC to turn off the DC.
3. Open the DC door.
4. Disconnect each liquid line connected to the valve.
5. Follow the instructions provided in the Rebuild Kit to replace the rotor seal,
isolation seal, and stator face.
To avoid injury, wait for the DC to cool down before opening the door
or performing any maintenance or service procedures.
Afin d'éviter toute brûlure, laisser refroidir le DC avant d'ouvrir la
porte ou d'effectuer des opérations de maintenance.
Um Verletzungen zu vermeiden, warten Sie bitte, bis der DC abgekühlt
ist, ehe Sie die Tür öffnen bzw. Wartungs oder Servicearbeiten
durchführen.
