ELECTRICAL CONNECTION
Make sure that the machine voltage corresponds to the supply voltage.
Electric supply has to be effected by interposing a magnetothermic differential three-pole
circuit breaker with opening distance of the contacts 3 mm or more. For the dimensions of
above refer to the "Technical data sheet" on page 1 of this instruction manual.
The section of the supply cables must not be inferior to that indicated in the "Technical data
sheet". If the cable is not protected use a flexible cable with protective covering in
polychloropene with characteristics matching at least type H07RN-F.
The cable must be connected to the disconnecting main switch "Q1" and to the terminal "PE" of
the grounding bar and then be blocked by means of the special cable tightener.
The electric safety of this machine is guaranteed only on condition that it is connected as
follows:
It is necessary to connect the machine to an efficient grounding system as foreseen by the
present standard in force for electric safety. Check this basic requirement and in case of any
doubt request that a careful control of the system be carried out by qualified staff.
The machine must be included in an equipotential system, whose efficiency has to be checked
according to the valid standard. The connection is effected by means of a screw with the
identification fitted to the back of the machine.
The manufacturer declines all liability for damages due to the lack of an efficient grounding
installation.
For the electric connection of the dispensers the machine is provided with two connectors
under tension in the electric board marked " DD " when the wash pump is running. The use of
these connectors is essential to avoid damages to the electric components of the machine, as
there are consequently no flying connections in other areas.
For the connection of the rinse aid dispenser, the machine is provided with two connectors
under tension in the electric board marked "
BB " when the rinse is running. Maximum
allowable absorption 1A.
HOT WATER CONNECTION (B)
A water tap has to be foreseen in an easily accessible place, to which the inlet filter has to be
connected. For dimensions of same please refer to installation drawing.
Strictly observe the national and regional regulations in force.
The dynamic pressure must not be less than 2 bar and not more than 4 bar (200/400 kPa). A
good result can be obtained if the incoming water has a hardness not exceeding 5/10°F and a
temperature of 55°C-0+10°C.
For a perfect rinsing result check that during operation the pressure on the manometer of the
pressure reducer corresponds to that indicated near the reducer itself.
