•
If needed, carry out an equipotential bonding,
using the screw placed on the rear of the machine
below the frame and marked with the symbol
shown to the left.
•
Make sure that the cold water supply line intended
for condensation has pressure values between 1
and 3 BAR and temperature between 13° and
20°C.
•
Connect the cold water supply pipe intended for
condensation onto the machine inlet as shown in
the figure. Use a Ø1/2” fitting and place a gate
valve in the operator's reach.
•
Connect the condensation water drain pipe onto
the machine outlet as shown in the figure, using a
Ø1/2” fitting.
•
Always use new pipes suitable for hot water and
for pressure up to 10 bar both for delivery and
draining. Never use worn or consumed piping. Use
suitable DIN 3017 hose clamps.
•
The drain pipe must have an inclination of at least
3 cm for each meter of length.
•
After having connected the water inlet and outlet
pipes, with the machine stopped, open the cut-off
cock and make sure that water does not leak from
the drain.
•
Turn off the master switch and press the
AUTOMATIC button on the batch freezer control
panel to check the following:
1. Motor rotation direction.
The machine is equipped with a sophisticated
electronic system which is able to automatically
detect if the beater motor rotation direction of
the batch freezer is the correct one (anti-
clockwise).
If the phases are inverted in the plug, after a
few seconds of operating in production mode,
the machine stops and the display shows the
relative alarm message. To connect the phases
properly cut the power and invert the two phase
wires in the plug.
