7.1 Washing procedure
Before washing the machine, make sure that the
main switch is turned to OFF.
The procedure for washing the filling machine is
as follows:
a- Prewash with hot water (50ºC).
b- Detergent wash. Use a foaming alkaline
detergent or gel detergent which is a powerful
fat emulsifier in a concentration of 2% to
10%, depending on how dirty the machine is
and on the hardness of the water supply.
c- Rinse with water. Wait 10 minutes and then
rinse thoroughly to remove the dirt emulsified
by the detergent.
d- Descaling wash. Use an acidic descaler with
low viscosity containing a mixture of wetting
agents and emulsifiers in a concentration of
2% to 3%. It should remain in contact for at
least 15 – 20 minutes.
e- Rinse with water.
f- Disinfectant wash. Use an appropriate
disinfectant diluted in water, in a concentration
of 1 – 1.2%. It should remain in contact for at
least 15 – 20 minutes.
g- Rinse with water.

7.1.2 C.I.P. washing
The C.I.P. washing cycle performs cycles of
dispenser opening and closing by keeping the
by-pass valve shut for the entire washing time.
The dispenser opens with the crosspiece in the
downward position and it closes with the
crosspiece in the upward position.
The duration of the washing and the opening/
closing frequency of the dispenser can be set up
to a maximum of 60 minutes with intervals of
maximum 60 seconds.
The C.I.P. washing envisages the following
phases:
a- Unblock the clamp lockups (Pos.1, Fig.7.1)
and remove the nozzles (Pos.2, Fig.7.1).
b- Fix the exhaust manifold (Pos.3, Fig.7.1) to
the dispensers with clamp lockups (Pos.1,
Fig.7.1).
c- Connect the delivery side and the return of the
detergent liquid to the by-pass valves (Pos.4/5,
Fig.7.1) and to the exhaust manifold (Pos.6,
Fig.7.1).
