Start-up of the machine
Connect the Freezer pump unit to a storage mixing tank with a pipe
A
made of rubber or flexible plastic. The pipe must not be more
than
4 meters
in length.
A rigid stainless steel tube should not be used.
Before starting the machine, open faucet
B
so that the thread of the
handwheel protrudes by approx. 4.5 cm.
Connect the panel to the power supply by pressing button
C
“RESET”
(light on).
Start the pump unit on pushbutton
.
Turn handwheel (
T
) (pump speed adjustment) clockwise to position
1.5
(black hand)
Set the air regulation valve (
S
) at the minimum value: Screw the
handle (
4
) clockwise till it gets fixed.
The first load of mixture must be without air.
When the liquid mixture begins to emerge from the outlet pipe,
tighten handwheel
B
so that the thread is approximately 1 cm from
the faucet.
Wait for the pressure inside the machine to reach
5 Bar
(this can be
read on pressure gauge
G
) and then stop the pump unit using
pushbutton
.
Start the mixing turbine
and the fridge compressor
in that order.
Wait a few minutes and then start the pump again by pressing
and inject air in the ice-cream by
unscrewing the handle (
4
) and manage to drag the ball (
5
) at the middle of the scale
(
6
).
While the machine is in operation, make sure that the pressure of the ice-cream inside the freezer, as
indicated on gauge
G
, remains between
10
and
13
Bar by tightening or loosening handwheel
B
of the outlet
faucet.
If production is low, the ice-cream will be too hard and the viscosity therefore increases until it stops the
fridge compressor for a few seconds. To solve the problem, increase the pump speed using handwheel
T
taking the value which appears on display
E
to a higher value (e.g.
200 Lt/h
).
If on the other hand production is too high and the ice-cream is soft, therefore viscosità is too low, reduce the
speed of the pump taking the value to
100 Lt/h
.
In the next few pages instructions are given to calculate the increase in volume and know what increase in
volume the ice-cream should have.
