Before connecting or disconnecting the power cable, switch the main switch onto position 0. If the power
supply cable is damaged, it must be replaced by the manufacturer, by its after-sales service technician or
similarly qualied persons, to avoid any danger.
For electrical safety, make sure that the device is properly earthed.
The manufacturer disclaims any liability for damage caused by improper earthing.
The device must be connected to a water network with a pressure of 1 to 8 bar (0.1 to 0.8 MPa) and a tap
readily accessible must be tted in front of the water supply tube. The device is to be installed with adequate
backow protection to comply with applicable federal state and local codes.
In case of emergency (re, surge, abnormal noise, etc. the rst thing to do is to cut o󰀨 the current and close
the water tap.
Be careful not to obstruct the air inlets of the machine with towels or other objects.
Beware of hot surfaces such as cup heaters, the unit heads and the hot water and steam outputs.
Never install containers lled with liquid on the top of the machine.
Beware of jets of hot water or steam.
The machine should be descaled only by a qualied technician.

3-MACHINE INSTALLATION
The machine must be installed on a horizontal plane.
A space of 5 cm (1.9”) should be left all around the machine; and do not obstruct the air inlets on the top of
the machine.
Provide an electricity supply corresponding to the power of the machine, a water supply and a “waste water”
drain.
►Preparation of the machine
The machine is delivered in a cardboard packing case and is screwed to a wooden pallet.
♦Unpacking the machine
- Cut the banding with shears.
- Open the packing case and remove the box containing the accessories.
- Unscrew the nuts holding the machine to the palette by tilting the pallet slightly.
- Separate the packing case from the pallet
- Remove the machine from the pallet and install it on wooden blocks.
- Remove the transport screws and washers.
♦Installing the machine
- Position the machine in its nal location, and level it using rubber washers if necessary.
♦Fitting high feet
Reference UNIC feet NSF: NM-176
Reference UNIC M8 x 16 bolts: 50402
For tting the aluminium feet, once the machine is installed in its location:
Screw the 50402 bolts to the aluminium feet, tip the machine onto the front
two feet to screw in the aluminium feet at the base of the rubber feet at the
back, and then do the same operation for bolting the feet to the front.
►Hydraulic connections
The machine is delivered with a complete connection kit including a stainless steel braided water hose 2 m
length and a drain hose 2m (78.7”) in length with a clamp located in the box of accessories.
- Slide the lower trims toward the front
- Remove the basin grille
- Remove the basin after unscrewing the central screw.
- Remove the right-hand side of the ACE,
- Screw the angled part (3/8’) of the stainless steel braided exible
pipe to the 3/8G tting of the water safety lter block and the straight
part (3/8’) on the water softener outlet union.
The water softener must be fed directly by the mains via a shut-o󰀨
tap allowing a su󰀩cient ow, Ø 8cm (3.1”) min.
Do not forget the seals. An opening in the chassis allows the hose
to pass through
- Put the softener in the ush position.
- Open the supply tap.
- Run a ush of the softener.
- Put the softener in the working position.
- Fit the drain hose on the tting located in the centre of the machine
- Check for leaks, and make sure that the drain tube allows a ow to
the main drain without any reverse slope.
- Ret the bowl, not forgetting the seal which must be between drain
blockandthebasin, and not between the central screwand the basin.
- Ret the trims and the basin grille.

►Electrical connections
Put the machine main switch in position 0, before any intervention.
The machine is delivered with a 5-core electric cable and a system of straps to allow for
3-phase or single-phase connection according to the installation.
The machine is pre-wired in accordance with the indications on the order and the country of destination.
Before connection, check the conformity of the machine with the electrical circuit to which it is going to be
connected.
To do this:
Compare the indications on the data plate, inside the drawer housing, with the characteristics of the circuit
to which the machine is to be connected. Remove the left side of the machine and check that the connection
of the straps on the terminal strip corresponds to the connection required (a diagram is glued to the inside of
the side).
ADAPTATION OF THE TOROIDAL TRANSFORMER TO THE VOLTAGE OF THE CIRCUIT
The machine is equipped with a multi-voltage transformer in order to ensure the correct supply voltage to the
electronics and 24-volt motors.
The machine is pre-set in the factory according to the country of destination (see page 6 and/or 7).
E.g.:
For Europe, the red wire is connected to the 230V terminal.
Oncetheconnectionhasbeenperformedcorrectly,itisnevertheless
advisable to check that the voltage is 230V± 5 %.
The low voltage should be about of 22V. These voltages should be
checked with the machine working and the main switch closed.

4-COMMISSIONING
►Switching on the machine and Turning on the heating
Once all the connections are made and checked (water supply, electricity supply and drain).
Set the main switch in position 1.
As soon as the electricity is switched on, the boilers ll automatically.
Remember to open the water tap supplying the machine.
The heating of all the parts starts automatically if the lling is correct.*
When the machine reaches its operating temperature, it performs a self-check.
Theseinitializationphasesare very important for the proper functioningof the machine.Theyareonlypossible
if the co󰀨ee grounds drawer is in place, and they must not be interrupted, for instance by removing the drawer.
(The steam pressure and the temperature of the groups are visible on the screen during heating).
The machine is operational once heating has been switched on and the self-check performed.
It is advisable to leave the machine heating on permanently.
