Under normal working conditions, your Reverse Osmosis (RO) water filter will not 
have any microbiological matter (bacteria) growing inside it. Unexpected extraneous 
conditions (eg temporary local water treatment problems, static water due to lack of 
use, poor maintenance etc) can result in bacteria growing inside your RO unit. Left 
unchecked, this bacteria can be detrimental to health in a clinical application and 
needs removing.
We recommend MONTHLY testing of the water dispensed from your RO unit with a 
TVC (total viable count) 

dipslide

 to check whether bacteria has grown inside the RO 

unit. In the unlikely event of your microbiological test detecting bacteria, we supply 
a simple ‘

RO cleaning kit

’ (supplier code EY90200-ST), which contains components 

needed to clean the RO system. In addition, you will need a 5L bottle of ‘

Cl

’ 

biofilm cleaner, all available from your local supplier.
A video for how to run the procedure is available online on YouTube, simply type in 
‘Clean Eau Flow 505 RO’ in the search bar.

decontamination processes that are purpose designed’.
