LabTower EDI
Ultrapure water system
41
To disinfect the Ultrapure water system proceed as follows:
1.
The Ultrapure water system must be in the “Stand by” operating mode.
2.
Switch the system off.
3.
Turn off the feedwater supply to the system.
4.
Open the dispensing valve until water no longer runs out and then close it.
5.
Remove the covering hood from the storage tank.
6.
Remove the cartridge cover from the system (refer to the “Changing the ultra pure
water module” section in the LabTower EDI operating instructions”).
Take off the quick connects from the feedwater and ultra pure water side of the ultra
pure water module and close the connectors with the stoppers that you have saved.
7.
Remove the ultra pure water module.
8.
Take hold of the disinfection cartridge and screw out the stopper from the lid of it. Fill
water in through the opening until the cartridge is full and then pour the contents of a
can of MICRO-Chlor in.
Important: The cartridge must be completely filled with water for successful
disinfection.
9.
Screw the stopper back in the lid of the disinfection cartridge and connect up the
cartridge in the system (as described in the “Changing the ultra pure water module”
section in the operating instructions for the system).
10.
Turn the feedwater supply on.
11.
Switch the Ultrapure water system on and allow it to run for 2 hours in “Stand by”
operating mode.
12.
Now open the residual drainage (dispensing valve) of the storage tank and discard all
of the water that runs out. Close the residual drainage.
13.
Fill the storage tank until the “Stand by” operating mode has been reached and empty
the tank as in 12. Repeat this process a second time.
Do not take any water from the dispensing valve or the storage tank during
disinfection.
14.
Switch the system off.
15.
Remove the disinfection cartridge and fit in the new ultra pure water module.
16.
Switch the system off.
17.
Finally replace the covering hood on the storage tank.
