Draining the internal 5 L and external 20 L tank

Note This process is required only when you operate your Dionex IC Pure system with a
pretreatment cartridge and without any external 20 L tank with level control.
CAUTION Without the external 20 L tank with level control, the concentrate of the pretreatment
cartridge is redirected into the tank, which degrades the feedwater purity and increases the
conductivity. Therefore, at a filling level of 30% the tank water needs to be changed to prevent the
shortening of the ultrapure cartridge lifetime.
