9.22 Rebuilding a High-Pressure (Injection) Valve
Thermo Fisher Scientific recommends rebuilding the injection valve annually.
The Injection Valve Rebuild Kit (P/N 074698; 4-port valve; 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 a
Dionex ICS-5000 Automation Manager.
NOTE
Substitution of non-Dionex/Thermo Fisher Scientific parts
may impair valve performance and void the product war-
ranty.
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.
2. Press the
POWER
button on the front of the DC for 2 seconds 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.
6. Reconnect all liquid lines to the injection valve.
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.
