The CIP washing cycle described above is the best
way of washing the machine with little need for labour.
If the washing system is not available and the machine
must be washed manually, it will be necessary to
dismantle a number of parts and reassemble them
very carefully after washing.
In this case, proceed as follows:
a-d. Turn off the machine as described in points a
through d above.
e. Disconnect the mix supply from the vat and
supply the freezer pump with warm water, no
hotter than 60 to 65ºC.
f. Start up the dasher using the switch (3- 6.3).
g. Start up the pump using the switch (2- 6.3).
h. Let hot water flow through the machine until
the water flowing out of it is fairly clean. Keep
washing as short as possible to prevent damage
to the pump.
i. Stop the dasher and the pump by turning the
switches (2- 6.3) and (3- 6.3) anti-clockwise.
j. Disconnect the pump delivery from the cylinder
intake (1) to let air out.
k. Remove the cover (2) by unscrewing the knobs
holding it in place.
l. Disconnect the pipes and the valve (5) on top
of the cover.
m. Remove the dasher (3) using the tool provided,
and dismantle the blades (6). Wear strong non-
slip gloves to protect against cuts from the
blades.
n. Dismantle the cylinder bottom (4).
o. Wash all components thoroughly, immersing
them in a solution containing the recommended
percentage of an appropriate detergent.
