INSTRUCTIONS FOR THE INSTALLATION TECHNICIAN
Installation
These Instructions are for the qualified technician, as a guide to the installation, adjustment and
maintenance, according to the laws and standards in force. Any of these operations must always be
carried out when the appliance has been disconnected from the electric system.
Positioning
(Fig. 5 - 5a - 5b). The appliance can be fitted into a working area as illustrated on the figure. Apply the
seal supplied over the whole perimeter of the working area.
Electrical connection
(Fig. 6 - 6a) Prior to carrying out the electrical connection, please ensure that:
- the plant characteristics are such as to follow what is indicated on the matrix plate placed at the bottom
of the working area;
- that the plant is fitted with an efficient earth connection, following the standards and law provisions in
force. The earth connection is compulsory in terms of the law.
Should there be no cable and/or plug on the equipment, use suitable absorption material for the
working temperature as well, as indicated on the matrix plate. Under no circumstance must the cable
reach a temperature above 50
°
C of the ambient temperature.
Should a direct connection to the network be required, it will be necessary to interpose an omnipolar
switch with minimum aperture between the 3 mm. contacts, dimensioned to bear the plate load and it
must follow the standards in force (the yellow/green earth cable must not be interrupted by the switch).
The plug or omnipolar switch must be easily reached on the installed equipment.
The manufacturers decline any responsibility in the event of non-compliance with what is described
above and the accident prevention norms not being respected and followed.
To avoid all risk, if the power cable becomes damaged, it must only be replaced by the
manufacturer, by an authorised service centre, or by a qualified electrician.
