5.2 Chemical disinfection
Immediately following the CIP, perform the disinfection, if required. The disinfection takes place with the
valve remaining in its closed position.
There are 2 recommended ways to carry out the disinfection:
A) by letting the disinfectant ow through the valve chamber
B) by lling the valve chamber with the disinfectant (advantage: smaller volume of disinfectant
needed and quicker and more reliable disinfection)
Steps to perform, when adopting A:
1. Connect a hose with an empty bottle to the lower hose piece. This
bottle or similar recipient is to collect the disinfectant (step 3) and the
rinsing water (step 6).
2. Fill a exible bottle with the dened amount of disinfectant.
3. Connect the exible bottle via a hose to the upper hose piece and
press the disinfectant slowly through the valve to wet the interior of
the valve.
4. Allow the disinfectant to act for the prescribed time.
5. Disconnect the hose from the upper hose piece and connect a exible
bottle with cleaned water to the upper hose piece.
6. Rinse through the upper hose piece by squeezing the bottle, thus
pressing the water through the valve chamber.
7. Leave the squeezed bottle connected to the hose piece and clamp
the hose to avoid contamination from air being sucked in through the
valve.
