In general, before calling technical assistance, switch the unit off and
on again.

CAUTION!
If the operator was not able to repair the anomaly, switch
the machine off and contact the manufacturer or the
authorised technical assistance with the details of the unit as dis-
played on the unit plate.

9. Disposal
At the end of the working life cycle of this product, its metal
components must be given to operators authorised in the
collection of metal materials for recycling, while all non metal
components must be given to operators authorised for their
separate disposal.
Products must be managed, if disposed of by the final client, as similar
urban waste and therefore respecting town laws in the town where they
are located. They must never however be managed as household waste.
• Check that the power supply is on and that the electric
connection is connected properly
• Check that the intake and return connection of the primary
exchange module is connected properly, if not, invert it
• Check that the flow switch is fitted correctly with the arrow
in the direction of the primary circuit flow, if not, invert it.
-• Check the functioning state of the circulator, and if it is
malfunctioning, carry out the above checks
• Check the primary and secondary circuit temperature and
lower the value set on the thermostatic mixing valve.
• Check the operational logic of the generator. NB: If the
circulator on the primary circuit stays on, the circulator
on the exchange module should also stay on but the
thermostatic mixing valve prevents the heat exchange
from cooling the inside of the tank.
• Check the status of the flow switch and the circulator
• Check the primary and secondary circuit temperature and
lower the value set on the thermostatic mixing valve
• Check the logic and control programming of the heating
element.
• Check that the power supply is on and that the electric
connection is connected properly
