A 4 pole plug, suitable with the current socket, must be installed at the end of the
device's power supply cable.
The device’s power supply cable is composed by 3 or 4 coloured wires, and eventually
marked with appropriate bands, which must be connected to the relevant plug’s termi-
nals, as shown in the following table.
A WRONG CONNECTION IN THE PLUG’S INSIDE MAY CAUSE SERIOUS
DANGER. FOR THE CONNECTION, ONLY ADDRESS YOUR SELVES TO
QUALIFIED AND AUTHORIZED TECHNICIANS.

Before using the device it is necessary to:
- connect it to the water network, if the device features a water condenser (Ref. Par. 5.5);
- carry out the initial functioning checking (Ref. Par. 5.6).
5.4 Connection to the water network
If your machine is provided with an AIR condenser, only water INLET pipe is necessary (for washing operations); in case the
machine is provided with a WATER condenser, both INLET and OUTLET pipes are necessary.
FOR THOSE MACHINES PROVIDED WITH A WATER CONDENSER: Do not let water from a TOWER in,
unless they have been specifically designed to utilize water from a tower. Unless otherwise specified,
the machine is designed to utilize water from a WELL.
Note: In the “Technical Data” section of the Technical Handbook you will find the necessary specifications regarding the
water’s correct temperature in order to operate the machine.
The use of below standard tubes and connections may cause water drops, with consequent inconven-
ience for Your laboratory and, if the drop is abundant with squirts, damage the device.
Use linen-rubber tubes for water connection, arranged for 218 PSI (15 bar), interposing a valve or a faucet [B] ABOVE the
delivery pipe; use a 3/4" rubber holder [C], well fixed with a proper band [D] to connect the tubes at the device’s union.
Note: Tubes for the water feeding of households are on the market (ex. dishwashers) which, in addition to being cheap,
feature the requested characteristics and are predisposed with a rubber holder.
Pipe unions are placed on the machine's rear panel, they are labelled [A] and marked:
IN: fresh water INLET
OUT: waste water OUTLET
Pipe unions for washing extraction tap [E] are placed on the machine,s rear panel.
