2.4 Special warnings
2.5 Ambient operating limits
2.6 Residual risks
The Frigus maker is used for combining ice-
cream mixture with sanitary air in fixed
quantities and, subsequently, for forming the
ice-cream with the addition of cold generated
by a refrigeration cycle.
The mixture of ice-cream and sanitary air is
blended inside a manifold by means of the
pressure of a rotating pump and the injection of
compressed air which is then pushed to the
cylindrical evaporator of a refrigerating system
for the treatment of ice-cream.
Several issues arise when adapting the pre-
printer to suit the needs of man: more precisely,
centralizing the controls on a single instrument
panel for the functions of adjustment and control.
The top lid of the freezing cylinder is interfaced
with a safety microswitch. The machine will stop
if the lid is removed.
All the transmission parts, the kinematic motions
and the refrigerating system are protected by
fixed boards.
Dismantling side panels (anchored in place with
screws) permits contact with moving parts.
This residual risk is referred to in section
3.5
Prohibition and hazard signs
and with a sign
indicating moving parts positioned on the
panels.
A signal of danger is placed on the flap of the
electric box to indicate live equipment.
For additional safety, the remaining risk is
recalled in paragraph
3.5 Instructions on ban
and danger signals.
