the fault situation autonomously

(**) If these two errors arise, check the pressure shown on the
hydrometer.
If the pressure is insufficient (< 0.4 bar - red field), perform the
filling operations described in the “Filling and draining the systems”
chapter.
If the system pressure is sufficient (> 0.6 bar - light blue field), the
fault is due to a lack of circulating water. Contact the Technical
Assistance Centre.

Temporary switch-off
In the event of a temporary absence, weekends, short journeys and
so on: press . The display will visualise the words “ENERGY FOR
LIFE” and the anti-freeze icon.
In this way (leaving the electricity and fuel supplies enabled),
the boiler is protected by the following systems:
-
Antifreeze
: when the boiler water temperature falls to 7°C, the
circulator is activated and, if necessary, also the burner (at the
minimum output) to bring the water temperature back within the
safety values (35°C). The icon will flash on the display, indicating
that the anti-freeze function is active.
-
Circulator anti-locking
: an operation cycle is activated every 24 h.
4.8
Switching off for long periods
The long term non use of the
Family Aqua Condens 3.5 BIS
boiler
causes the execution of the following operations:
- press . The wording “ENERGY FOR LIFE” and the antifreeze
icon are displayed
- set the system's main switch to "off"
- turn off the fuel and water taps of the heating and domestic hot
water system.
In this case, the anti-freeze and anti-blocking systems are
deactivated.
Drain the heating and domestic water system if there is any risk
of freezing.
4.9
Maintenance
Periodic maintenance is an “obligation” required by law and is
essential to the safety, efficiency and lifetime of the boiler.
It allows for the reduction of consumption, polluting emissions and
keeping the product reliable over time.
Before starting maintenance operations:
- perform the analysis of the combustion products to check the boiler
operation status then cut the electrical supply by turning off the
system’s general switch
- close the fuel and water taps of the heating and domestic hot water
system.
The appliance must be systematically controlled at regular intervals
to make sure it works correctly and efficiently and conforms to
legislative provisions in force. The frequency of controls depends on
the conditions of installation and usage, it being anyhow necessary
to have a complete check carried out by authorized personnel from
the Servicing Centre every year.
- Check and compare the boiler’s performance with the relative
specifications. Any cause of visible deterioration must be
immediately identified and eliminated.
- Closely inspect the boiler for signs of damages or deterioration,
particularly with the drainage and aspiration system and electrical
apparatus.
