DANGER!
Scheduled maintenance must be carried out by
skilled technicians, qualified to work on

schedule an overall inspection at regular intervals to prevent
malfunctions which could damage the main machine components (see
SECTION II: INSTALLATION AND MAINTENANCE).

PROLONGED SHUTDOWN

When the appliance is not used for long periods of time, disconnect it
from the power supply by means of the main isolator switch.
IMPORTANT!
If the unit is not used during the winter period, the
water contained in the system may freeze.
All the water contained in the circuit must be emptied before the onset
of winter. During installation, consider mixing the water in the circuit with
the correct proportion of ethylene glycol (antifreeze) to guarantee
protection against freezing (see SECTION II: INSTALLATION AND
MAINTENANCE).
To reset the alarm, press the
PRG/mute key for 5 seconds.
If the alarm is properly reset,
