distribution of heat through the ventilation
during installation, it is necessary to establish the type of ventilation or convection to be adopted.
ventilation of the installation room
Our products are equipped with series tangential fans suitable to improve the distribution of heat through the ventilation exclusively
of the installation room (see
ventilation of the adJacent local
The covering of each product is equipped with outputs for the connection of pipes resistant to heat.
a) Perform the drilling on the walls or on the existing hood to allow the passage and the application of the (fire-resistant) hoses with related
openings.
b) Fasten the pipes by means of clamps to the related collars and openings, after having removed the semi-blanks caps (see
c) Each pipe must not exceed 1.5 m of length for natural ventilation; it must be insulated with insulating materials to avoid noise and
dispersion of heat.
d) The openings have to be positioned at a height not lower than 2 m from the floor to avoid that hot air at output meets people. Please respect
the distance of the convection openings according to the local construction norms;
e) The lengths of the canalization pipes must have the same length to avoid the distribution of differing quantities of air from each output (see
Picture
10).
f ) If the space between the upper part of the insert and the lower profile of the hood is lower than 10 cm, it is necessary to perform a hole of
about 30 x 40 cm on the hood to allow the fastening of the hoses;
connection and maintenance of ventilation
the control unit and the plant must be installed and connected by authorized personnel according
to the standards in force (see chapter WARNINGS - chapter GENERAL PRECAUTIONS).
attention: the control unit and the feeding cable must not be in contact with hot parts. in any case,
the power cable has to be replaced by authorised personnel only (ENTITLEd by LA NORdICA): authorised
dealers and/or fitter.
Our products are equipped with tangential fans suitable to improve the distribution of heat (see chapter dISTRIbUTION OF HEAT THROUGH
THE VENTILATION).
The lighting and the adjustment is carried out through the proper standard supplied control unit that has to be installed far from any direct
heat source.
connection: Connect the power supply cable of the control unit to a bipolar switch respecting at least a 3 mm distance between the
contacts (power supply 230 V~ 50 Hz, it is necessary to provide for the correct connection to the grounding plant).
this operation must be done without electric energy!!
warning: THE COMMANd MUST bE CONNECTEd TO THE MAINS WITH A dIFFERENTIAL LINE CUT-OFF SWITCH ACCORdING
TO THE REGULATIONS IN FORCE. CORRECT OPERATION OF THE COMMANd IS ASSUREd ONLy FOR THE PROPER MOTOR FOR
WHICH IT HAS bEEN MANUFACTUREd. improper use relieves the manufacturer from each responsibility.
