LAWS, REGULATIONS AND TECHNICAL DIRECTIVES

The following indications should be observed during installation:
- Accident and fire regulations in force
- The regulations of the electric power supply company.
- Hygienic regulations.
- The rules for electrical systems.
2.3

INSTALLATION PLACE

- The unit should be installed in adequately ventilated places.
- Install the unit in compliance with the safety regulations.
2.4

POSITIONING

- The various units may be installed individually or together with other units of our OPTIMA range.
- This unit is not suitable for encasing.
- The distance between side walls must be a minimum of 10 cm; should the distance be less or the wall or floor material be
flammable, it is essential to use a thermal insulator.
2.5

WATER CONNECTIONS

In order to perform a correct installation, it is essential that :
- The unit be supplied with drinkable water.
- The water inlet pipe be connected to water main by check-valves to be shut off when the unit is not operating or when
servicing it.
- Between check-valves and the pipe connecting the folding, mechanical filter be installed in order to prevent any ferrous slag
to be introduced, which may corrode by oxidation and in the long run oxidise the folding itself. It is advisable, however,
before connecting the last piping section the folding fittings, to drain a certain amount of water in order to clear the pipes
from any ferrous slag.
2.6

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 label 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.
2.6.1

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 (
on the line-receiving terminal board. The earthing system should comply with the law in force.
SPECIFIC WARNINGS
The electrical safety of this unit is assured only when it is correctly connected to an efficient earthing system as stated
in the electrical safety regulations in force; the Manufacturer declines any responsibility for the non-compliance with
these safety regulations.
It is necessary to verify this fundamental safety requisite and, in case of doubt, ask for an accurate testing of the system by
professionally qualified personnel.
The Manufacturer cannot be deemed responsible for any damages caused by the lack of unit earthing.
ATTENTION: NEVER INTERRUPT THE EARTH WIRE (Yellow-Green).
2.6.2

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 near the terminal board on the base for models with oven, and at
the back for the remaining models.
