Anti-freeze function
Your ARIANEXT system is equipped with an anti-freeze function,
which checks for the outlet water temperature of the internal unit and
manages the activation of the devices of the system, in case the tem-
perature remains below 8 ° C for more than two consecutive minutes.
ATTENTION
Anti-freeze function works properly only if:
· System pressure is included between 0.6 and 3 bar
· The system is electrically supplied
In correspondence of anti-freeze function activation request, no
errors are occurring
Maintenance
The maintenance of your ARIANEXT system is compulsory and indi-
spensable in order to ensure an adequate functioning, the safety of
the appliance and the duration of life of the system itself.
