detergent with as much as 50% the ensuing
alkaline cleaning.
Ensuring sufficient regularity of alkaline
cleaning is especially important for VMS
since the milking station make use of
DeLaval milk meter MM25 equipped with
conductivity-measuring electrodes. A
phosphated, alkaline detergent such as
DeLaval Ultra must be used in order to
remove impurities on these electrodes, and
consequently to ensure proper functioning
of the milk meters.
Note: The table must be followed with
flexibility since the conditions may change in
different farms. After changing the detergent
dose, the result should always be checked
up to six weeks.

Alternating acid and alkaline
detergent
The parameter settings for the cleaning
strategy that alternates between acid and
alkaline detergent are described in chapter
"Milking station" in the instruction book
"VMSMgmt 2007".
Always consult your DeLaval service
engineer before changing parameter
settings. Some parameters may also need
authorisation to be changed.
Note: Mixing of an alkaline chlorinated
cleaning solution with an acid cleaning
solution should be avoided; the solutions
may react and produce poisonous gasses.
