5. USE OF THE PRODUCT
• This product is not supplied with any switch or device for controlling temperature and must
be regulated by appropriate devices that should be contemplated in the plant construction
phase (E.g. differential switches and circuit breakers).
• In versions with 2 or 3 resistances there is the possibility of designing different power supply
circuits, so it is possible to activate the product partially when less heating is needed. In the
versions with 3 resistances, for example, it is recommended to have a circuit supplying the
central element (Phase L2) and another for the side elements (Phases L1 and L3) so it is
possible to use 1/3, 2/3 or 3/3 of the available power, as needed.
• Attention! After the initial installation and during the first few hours of operation, the product
may give off an unpleasant smell and/or a small amount of fumes. This is caused by the
presence of traces of substances used in the production process and it is not a defect or
product malfunction nor does it pose any danger to the safety and health of users.
