Note This additional tank indicator has already been
calibrated at the factory. If recalibration is required refer
to "Recalibration of the tank sensor for an additional
tank indicator" .
Note Fill the external 20 L tank with ASTM Type II
water.
When using the pretreatment cartridge option and the
content of the external 20 L tank has reached a level of
30%, drain the remaining tank water and fill the
external 20 L tank manually again with ASTM type II
water.
It is necessary to reduce the ionic content of the
feedwater in the external 20 L tank. The concentrate
back flow from the Dionex IC Pure system into the
external 20 L tank, multiplies the ion content of water in
the external 20 L tank.

the unit and check the filling level.
Connecting the external 20 L tank with level
control (optional)
Note The external 20 L tank with level control allows the automatic filling of the external tank. The
external 20 L tank with level control must be connected to a pressurized source. The feedwater
pressure may not exceed 400 kPa (58 psi). If the pressure is higher, an additional pressure regulator
must be installed.
Note To hook up the external 20 L tank with level control, ensure the Dionex IC Pure system is
turned off, unplugged from power supply and the 5 L internal tank should also be drained.
CAUTION When operating the Dionex IC Pure system without a pretreatment cartridge, connect
the external 20 L tank with level switch control to a central system that supplies ASTM Type II
pretreated water. If you are using a pretreatment cartridge in the Dionex IC Pure system, connect the
external 20 L tank with level control to a potable water supply. Additionally, route the concentrate line
directly to an atmospherically vented drain.
