4.5 ACTIVATION (INTENDED FOR QUALIFIED PERSONNEL)
FRIGOMAT declines all and any liability for damage caused by failure to comply with the
following indications. This lack of compliance causes the warranty to terminate.
Connection of the machine to the water mains must be performed in compliance with
national regulations of the Country where the machine is installed.
To commission the machine, bring it to the place of use, checking what is requested for its
installation:
1. Electrical power supply 3 phases + neutral + earth (5 wires);
2. Cold water mains supply (13° - 20°C);
3. Condensation water drain.
•Make sure the appliance is positioned on a solid, stable, flat and levelled surface.
•Block the machine by acting on the relevant brake lever on the rear wheels.
•Leave at least 10 cm between the machine and the walls or other obstacles.
•Check the exact correspondence between the voltage and power of the mains
compared to the values carried on the data plate applied on the rear panel;
•Connect the machine to the electrical power supply system. Install a omnipolar master
switch upstream the appliance with minimum contact opening of 3 mm of adequate
power, with a fuse and circuit breaker protective system. Use an approved interlocking
plug to allow only the open circuit to connect and disconnect.
•The cable must be well laid, without being rolled-up or overlapped. It must not be
exposed to blows or tampering. It must not be in the vicinity of liquids or water and heat
sources. It must not be damaged in any way. If so, before connecting the machine to
the mains, have it replaced by qualified personnel with another having a 5G4 H07RN-F
(400 V version), 5G6 H07RN-F (220 V / 3 version) cross-section.
•For safety purposes, make sure the earthing system to which the machine plug is
connected is compliant with standards and perfectly efficient.

ENGLISH
•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.

2. Condensation pressure
With the machine in production mode, After a
few seconds condensation water must come
out of the drain pipe at a temperature of about
C136°C. If this is not the case, the pressure
switch valve shown in the figure must be
adjusted.
Three-phase machines are powered with three-
phase + neutral lines: be careful never to
connect the phase lines with neutral.
FRIGOMAT will not be held liable for damage
to the machine deriving from non-compliance
with this rule.
•Press the STOP button to stop the machine .
•Operating temperature should be between 15° and C136°C.
•Humidity should be between 30 and 60%.
FRIGOMAT s.r.l. will not be held liable for personal harm and/or damage to objects
deriving from incorrect installation and/or by failure to comply with work Accident-
prevention Standards. Never intervene on the machine with your hands, neither during
normal operating cycles or during cleaning and maintenance, without first having stopped
the machine by pressing the STOP button and having turned off the master switch. Never
clean the appliance using a high-pressure water jet. Never shut the water cut-off cock
while the machine is running. Be careful never to damage the power cable. If so, have it
replaced.
Machines with water cooling which are left in places at a temperature below or close to
0°C, must first have all the water drained from the condenser.

5. SAFETY DEVICES
Limbs shearing-prevention safety device (batch freezer): Implemented by means of a
safety circuit compliant with the European directive, it intervenes when the door is opened
and/or when the safety grid on the hopper is lifted, temporarily switching the machine to
STOP mode.
Limbs shearing-prevention safety device (heater): Implemented by means of a safety
circuit compliant with the European directive, it intervenes when the lid is opened,
temporarily switching the machine to STOP mode.
Motor overheating safety device: Implemented by means of automatic reset thermal
relays; they protect the machine's beater motors from overloads, by signalling the relative
alarm message on the display, emitting an intermittent acoustic signal and enabling to
reset directly from the push button control panel.
Semi-hermetic compressor motor overheating safety device: Implemented by means
of an automatic reset thermal relay; it protects the machine compressor motor operation
from overloads, by signalling the relative alarm message on the display, emitting an
intermittent acoustic signal and enabling to reset directly from the push button control
panel.
Chiller circuit over-pressure safety device: implemented by the approved automatic-
restoration safety pressure switch; it protects the integrity of the chiller circuit from
overpressure.
Heat elements safety device: implemented by means of safety thermostat; it protects the
heat element from overheating, by signalling the relative alarm message on the display,
emitting an intermittent acoustic signal and allowing restore directly from the push button
control panel.
Protection against short circuit of auxiliary utilities: Implemented by fuses which
intervene on the logic unit or auxiliary power supply in the event of short-circuits.
SELV safety circuit: the push button control panel is powered at low voltage by means of
an approved dual-insulation safety transformer, protected against short circuits by fuses.
Bain-marie fluid level safety device: implemented by a conductivity probe inside the tank
which signals alarm on the display and coupled with an intermittent acoustic signal if the
fluid level is insufficient.
