Trouble-shooting faults in the pump unit
FAULTS IN OPERATION CAUSES REMEDIES
Leakage of mixture under the
machine where the pump unit
is located
O-ring (3) are worn or broken
Check and replace if necessary
Ice-cream does not contain air
(does not increase in volume)
Compressed air is not reaching the
machine.
Compressed air is not reaching the
pumps.
It is possible that the check valve
of compressed air (22a) is blocked
or glued to its washer (22g)
Check the compressed air unit inside
the machine. Check the pressure
regulator S, see page 15.
Check and replace O-ring (22g).
Ice-cream has too much air in
it although the same pressure
of compressed air was used.
Mixture reaching the machine is
too cold and therefore stickier so
that the pump in the first stage has
difficulty in sucking it up.
The mixture storage tank is too far
away (more than 4 m.) and the
pump in the first stage has
difficulty in sucking it up.
Check the temperature of the mixture.
Check the distance of the tank and if it
is not possible to bring it closer, use a
servo-freezer positioned close to the
machine.
