p. Rinse well in running water.
q. Reassemble the parts in precisely the same
position as before.
Be very careful when positioning the blades (6);
the sharp part must be facing the cylinder. The
latch on the cover (2) of the cylinder between
the knobs is connected with a safety system;
when closing the cylinder again, tighten up the
knobs (by hand) to enable machine operation.
WARNING:
To prevent blows that could damage the freezer
cylinder, a “shaft raiser ring” is supplied. The ring
must be positioned on the cylinder as shown in the
figure below. Then assemble the shaft (3), being very
careful not to hit and damage the ring on the
mechanical seal at the bottom (4). Finally, remove
the ring and continue assembling all parts.
r. Sanitise the freezer by pumping a sterilising
solution. Rinse and then drain the solution.
s. Before beginning production, it is
recommended that rinse water be pumped
through the system for 2 to 3 minutes. Drain
the water by disconnecting the pump from the
cylinder.
t. The freezer is now ready for use again.
