10 - MAINTENANCE
10.3 - Check the water pressure in the
system and there are no leaks
1.- Check that the system is full of water and under pressure
as reported in section 11. The check must be performed
with the system cold and after each filling of the same;
2.- Check there are no leaks.
WARNING!!! Eliminate any leaks to the system
or to the appliance. The continuous supply of new
water involves an increase in minerals which reduce
the passage section, decreasing the heat exchange and
causing overheating of the heat exchangers. All this will
lead to breakdowns and a reduction in the life of the
device itself.
10.4 - Check the good condition of the
safety valve
1.- Visually check the safety valves for obstructions in the
exhaust duct, signs of corrosion, physical damage, water
stains or signs of rust.
2.- In case of obstructions in the exhaust duct, proceed with
cleaning it, if on the other hand you find other types of
damage indicated above, replace the valve.
10.5 - Check and clean the safety exhaust
valve system
1.- Visually check that the exhaust safety valve do not show
obstructions in the ducts and in the drain conveyor;
2.- In case of obstructions in the exhaust duct, proceed with
cleaning it, if on the other hand you find other types of
damage indicated above, proceed with the replacement.
10.6 - Check the good condition of the
safety and control devicees
1.- Check, by querying the device diagnostics (section 9), any
interventions of the safety and control devices;
2.- Visually check that the safety and control devices show
no signs of corrosion or physical damage;
3.- In case of damage indicated above, replace them.
10.7 - Check the good conditions of the
electrical system
1.- Access the internal components of the appliance as per
section 10.24;
2.- Visually check that the cables are in the relative cable
glands, that the plug-in connections are correctly secured
and that they do not show any signs of blackening or
burning,
3.- In case of damage indicated above, replace the damaged
cables.
10.8 - Check the operation of the main
switch
1.- Verify, by installing an external magnetothermic switch,
the switching off of the device when the main switch is
positioned on OFF and vice versa when it is switched on
when it is positioned on ON;
2.- In case of malfunction, proceed with replacing the switch.
10.9 - Check the temperature adjustment
in heating and DHW
1.- Check the relationship between the regulated temperature
and the actual one obtained in heating and DHW mode;
2.- If the temperatures do not match, replace the sensor
concerned and if the problem persists, replace the
thermoregulator.
10.10 - Check the good conditions and
operation of the vent valves present
1.- Visually check that the vent valves do not show
obstructions, signs of corrosion, physical damage, water
stains or signs of rust;
2.- In case of one or more of the signs listed above, replace
the valve.
10.11 - Check the expansion tanks
The appliance is not equipped with expansion tanks. They
must be provided (by a qualified technician) according to the
type of use (domestic hot water / heating) and the calculated
necessary volume. Therefore, their maintenance must in any
case be performed according to section 10.2.
10.12 - Check that the evapocondensing
battery is clean
Check the cleanliness of the battery fins: if they are partially
blocked by leaves, dust or debris, proceed with cleaning using
a soft brush.
In case of particularly stubborn dirt, proceed with a jet of
pressurized water, paying particular attention not to damage
or deform the fins.
10.13 - Check there are no leaks in the
refrigerant circuit
Check that the operating pressures and temperatures of the
refrigerant circuit are regular.
This is possible by accessing the “Info” menu (section 8.2.15).
If it is understood that the refrigerant circuit no longer has the
correct refrigerant charge, before restoring it, carefully check,
with an electronic leak detector, all the connections and pipes
of the refrigerant circuit in order to search for any leaks and
eliminate them.
10.14 - Check the good conditions of the
electrical connections
1.- Visually check that the cables are in the relative cable
glands, that the plug connections are correctly fixed and
that they do not show signs of blackening or burning;
2.- In case of damage indicated above, replace the damaged
wiring.
10.15 - Check the status of the fan
Check that the fan does not make abnormal noises during
operation due to misalignments and / or bearing problems.
In case of malfunctions, proceed with the replacement of the
fan and / or the motor.
10.16 - Check the control devices
1.- Check by the device diagnostics (section 9) any
interventions of the safety and control devices;
2.- Visually check that the control devices do not show signs
of corrosion or physical damage;
3.- In case of damage indicated above, replace them.
