WATER CONNECTION AND DRAIN

In order to carry out a perfect installation, make sure that:
- the device is fed with drinkable water
- the water inlet pipe is connected to the distribution system through a gate valve
that closes when the device is not operating or when it needs maintenance operations
- between the gate valve and the pasta cooker's connecting pipe, a mechanical filter
has to be installed in order to avoid the penetration of iron impurities ; after
oxidation, they may corrode and damage the container because of oxidation.
- it is recommended (before connecting the last part of the pipe to the pasta cooker
coupling) to let some water run in order to drain the pipe from any possible iron
impurity.
DRAIN
Convey the pasta cooker drain pipe (position 1) towards an open-type siphon (position 2) so as to avoid the contact between
the drain pipe of the device and the collecting siphon, in compliance with the hygienic rules applicable in the relevant
country.
The drain of the device is to be connected in such a way as to enable the pipe to withstand a temperature of roughly 100 °C.
2.4

ELECTRICAL CONNECTION

Electrical connection should be performed in compliance with the IEC regulations, only by authorised and competent
personnel. In the first instance, examine the data shown on the technical data table of this manual, on the serial plate and on
the electrical diagram.
The envisaged connection is of the fixed type.
IMPORTANT: Ahead of each unit it is necessary to install an omnipolar main breaker, having a spacing among contacts of
at least 3mm; example:
- manual breaker of appropriate capacity, complete with fuse valves
- automatic breaker with respective magnetothermal relays..
2.4.1

EARTHING

It is essential to earth the unit.
To this purpose, it is necessary to connect to an efficient earthing system the terminals marked with the symbols ( ) placed
on the line-receiving terminal box. The earthing system should comply with the law in force.
The Manufacturer cannot be deemed responsible for any damages caused by the lack of unit earthing.
ATTENTION: NEVER INTERRUPT THE EARTH WIRE (Yellow-Green).
2.4.2

EQUIPOTENTIAL

The unit should be included within an equipotential system whose efficiency must be tested according to the law in force.
The screw marked with the label "Equipotential" is located on the back.
2.4.3

POWER SUPPLY CABLE

The unit is supplied fitted for the following voltages: 3N AC 380...415V; 2N AC 380...415 V; 3 AC 220...240V; 1N AC
220...240V 50/60 Hz.
The flexible cable for power supply connection should not have characteristics lower than the rubber insulation type
H07RN-F. The cable should be inserted through the cable clamp and firmly fastened. Furthermore, the supply voltage with
the unit functioning should not go outside the value of the nominal tension ±10%.
This equipment is provided with a cable having the characteristics specified in Table 3 (page 7); to have access to the
terminal board or to replace it, proceed as follows:
- remove the front panel
- connect the cable to the terminal box according to need, and following the instructions shown on the provided label near
the terminal bord and on the present booklet.
