3.2. Draining
The drain pipe must be connected to a well or to an air-trap on the floor. Make sure that the drain pipelines in the
wash area are not choked and that they guarantee a quick water outflow. The wall drain pipe must withstand at
least 70°C. This appliance has a gravity drain, therefore the drain should be lower than the tank outlet. If the
machine is equipped with a drain pump, the position of the drain can be on a wall but its position cannot be higher
than the value indicated in fig.D.
4. ELECTRICAL CONNECTIONS
When connecting the machine directly to the electric mains, always use a surge protection device with a contact
gap that allows for complete disconnection in the case of Overvoltage Category III, in compliance with installation
regulations.
Check the integrity of the power cable: if damaged, it must be replaced by the manufacturer, a service centre or
qualified personnel in order to avoid potential hazards.
A "H07RN-F" power cable must be used. Cable cross-section: 5x2.5 mm
the cable may be: 4x4 mm
AN EFFICIENT EARTHING SYSTEM GUARANTEES THE SAFETY OF THE OPERATOR AND THE APPLIANCE.
This is an essential requirement that must be checked and, if in doubt, have the entire electric system checked by
the qualified personnel which made the connections to the electric mains. THE MANUFACTURER WAIVES ALL
RESPONSIBILITY FOR ANY DAMAGE CAUSED BY LACK OF AN ADEQUATE EARTHING SYSTEM FOR THE
APPLIANCE.
It is strictly forbidden to use plug adapters, multiplication plugs and extension cords.
Verify that the electric power supply complies with the technical specifications. The machine must be part of an
equipotential system, in accordance with European regulations. Connect it using the screw (C-9) with the mark, on
the back of the machine.
The connection to the electric mains must be done using a multi polar magnetothermic differential switch rated with
a contact gap equal to or larger than 3 mm.
When selecting the type and size of the power cable consider: the distance between the machine and the power
connection point, the installed power indicated on the ratings plate and the mains tension. The cross section of the
cables must not be less than 2,5 mm
block with cable clamp. Both components are as standard equipment. Avoid any strain on the power cable.
Verify the safety thermostat of the boiler F-B3 (if mounted) by pressing the reset button. The machine is set with a
boiler temperature of 85°C.
5. Accessories
The machine can be fitted with retrofit accessories at a later date even on standard versions and available upon
request:
•
peristaltic detergent dispenser
•
peristaltic rinse-aid dispenser
•
drain pump
•
rinse pump
models with water softner must be ordered directly at the manufacturer.
6. Maintenance of the peristaltic dispensers
:replacing the internal tube:
1) remove the transparent cover.
2) to remove it place the roller case vertically;
3) remove the coupling on the left of the pump from its seat by pulling the tube upwards and following its full length,
then turn the roller case clockwise until the coupling on the right of the pump can be extracted;
4) to mount it place the roller case horizontally;
5) push down the coupling on the left of the pump, with the curved part facing the bottom.
6) press the tube into its seat, gradually along its full length, and then manually turn the roller case clockwise until
the right-hand coupling is also inserted correctly;
7) fix the protection cover again then place the dispenser in the appropriate seat.
Use the regulation screw of the dosing unit (Fig.H.). By turning it clockwise or anti-clockwise the product quantity is
increased or decreased. The dosing times go from 1 to 25 seconds.
A 0.2 g quantity of rinse-aid corresponds to 2 cm in the transparent feed tube (cross-section 4x7 mm).
The dispensers must never be used when empty, or allowed to become empty.
Read the unit "Peristaltic dispensers" in the section "Use" to fill the dispenser and the dispenser/tank connection
tube.
7. SAFETY PROVISIONS AND USER TRAINING
The skilled personnel performing the installation and the electric connections are requested to instruct the user
aptly about the functions of the appliance and the safety provisions to respect.
