Dionex IC Pure system

Unplug the system from the power outlet for all maintenance work on the system.

The installation area must have a drain at floor level with at least a nominal outer diameter of 63

mm or 2.48 in (DN 50 pipe). Should no such drain be available, it is recommended to install a
water watcher (only for European specification). Otherwise, the manufacturer will not accept
liability for any possible water damage.
Proceed as follows if the unit is inactive for an extended period, e.g., over extended weekend, or

during a vacation period:
Switch the system off (unplug the main power plug).

Close the feedwater inlet (close the feedwater tap).

The pump would be damaged if the unit were to run without any supply of feedwater. The
manufacturer will not accept any liability should this occur.
The unit must be disinfected or rinsed after an extended down time. The rinsing procedure is

explained under "Rinsing procedure" on page 69, and the disinfection procedure under
"Disinfection procedure" on page 66.
The surface or wall on which the unit is to be installed or mounted must have an adequate

load-carrying capacity (check the capacity and stability of the wall). The dry weight of the unit is
given under "Dimensions and weight of Dionex IC Pure system (50132810) with ultrapure
cartridge (09.1006)" on page 14. When the internal tank is filled, the unit has a weight during
operation of approx. 32 kg (70.55 lb).
The surface on which the unit is installed must be level and stable - not to exceed a maximum of

2% deviation from evenness is recommended.
When installing the water purification unit, always ensure that there is adequate space all

around the unit (see "Accessibility to Dionex IC Pure system and external 20 L tank" on
page 16) to ensure that ease of use or easy replacement of materials (e.g., filter change,
connection) is possible at all times.
Visually inspect the unit at regular intervals. Clean up any water or spills found around the unit

immediately.
CAUTION Never look directly into a switched-on UV-lamp, as UV-light endangers eyesight!
CAUTION To avoid the risk of pinching, crushing, cutting or electrical shock, never perform
maintenance on the unit without its protective housing, or while it is in operation. Maintenance work
on the unit may only be performed by trained, authorized specialists.
