that they do not play with the appliance.
2.2. Safety
Use is allowed only if the electric system is in possession of safety precautions in accordance with the regulations in force in
the country where the product is installed (for Italy, CEI 64/2).
2.3. Responsibility
The Manufacturer does not vouch for correct operation of the set or for any damage that it may

The Manufacturer declines all responsibility for possible errors in this instructions manual, if
due to misprints or errors in copying. The company reserves the right to make any

3. INSTALLATION
3.1. The set must be fitted in a well ventilated place, protected from unfavourable weather conditions and with
an environment temperature not exceeding 40°C (fig.1).
Position the set in such a way that any maintenance jobs can be carried out without difficulty.
3.2. Ensure that the system pipes are independently supported and do not weigh down on the set manifolds so as
to avoid deformation or breaking of any of its components (fig.2).
It is also advisable to insert vibration-damping couplings on the system manifolds.
