FIXING OF THE PRE-ASSEMBLY TEMPLATE (fig. 5)
The
Family Aqua Condens 3.5 BIS
boiler is designed and built to be
installed in heating and domestic hot water systems.
The position and dimension of hydraulic fittings are shown in the
drawings.
- Position the plate with the aid of a spirit level: check the correct
horizontal plane and the planarity of the boiler rest surface; make
it thicker if needed.
- Trace the fixing points.
- Remove the template and carry out the drilling.
- Fix the plate to the wall using appropriate plugs.
- Check the correct horizontality with a spirit level.
FIXING THE BOILER
- Hook the boiler to the brackets on the plate.
FIXING OF THE CONNECTIONS COVER - accessory available
by reques (fig. 6)
On completing boiler installation operations and relative connections
to the water and gas mains, fit the connections cover (
A - B
) so that
its hooks fit into the specific slots in the lower part of the boiler. Fix
the connections cover with screw
C
.
3.7
Hydraulic connections (fig. 10-11-12)
Connect the fittings and gaskets supplied with the system.
We recommend connecting the boiler to the systems introducing
both the DHW shut-off valve as well as the shut-off valves for the
heating system; for this purpose a heating system valves kit and
heating valves kit with filter is available.
Connect brass taps supplied to the fittings and the boiler.
The selection and the installation of the system components are
the responsibility of the installer, who must operate according
to the rules of good technique and current legislation.
A carrying case kit is available that allows to make connections
quickly and without unnecessary waste on each system.

DISCHARGE MANIFOLD
The discharge manifold collects: condensate water, any evacuation
water from the safety valve and the system discharge water (fig.13).
The manifold must be connected via a rubber pipe (not
provided) to an appropriate collection and evacuation system
in the white water discharge drain in compliance with current
regulations. The outer diameter of the manifold is 20 mm: it is
therefore advisable to use a rubber pipe ø18-19 mm closed
with a suitable clamp (not provided).
Regularly check that the discharge manifold is not blocked by
solid residues that might prevent the outflow of condensate
water.
The manufacturer is not liable for any damage resulting from
the failure to channel the condensate.
Sealing of the condensate drainage connection line must be
guaranteed.
The boiler manufacturer is not responsible for any floods
caused by the intervention of the safety valves.
3.8
Installing the external probe
The correct operation of the external probe is fundamental for the
good operation of the climatic control.
INSTALLING AND CONNECTING THE EXTERNAL PROBE
The probe must be installed on an external wall of the building to be
heated, observing the following indications:
- it must be mounted on the side of the building most often exposed
to winds (the NORTH or NORTHWEST facing wall), avoiding direct
solar irradiation;
- it must be mounted about 2/3 of the way up the wall;
- it must not be mounted near doors, windows, air outlet points, or
near smoke pipes or other heat sources.
The electrical wiring to the external probe is made with a bipolar cable
with a section from 0.5 to 1 mm
2
(not supplied), with a maximum
length of 30 metres. It is not necessary to respect the polarity of the
cable when connecting it to the external probe. Avoid making any
joints on this cable however; if joints are absolutely necessary, they
must be watertight and well protected.
Any ducting of the connection cable must be separated from live
cables (230V AC).
FIXING THE EXTERNAL PROBE TO THE WALL
The probe must be fixed on a smooth part of the wall; in the case
of exposed brickwork or an uneven wall, look for the smoothest
possible area (fig.14).
Loosen the plastic upper protective cover by turning it anticlockwise.
After deciding on the best fixing area of the wall, drill the holes for the
5x25 wall plug.
Insert the plug in the hole.
Remove the card from its seat.
Fix the box to the wall, using the screw supplied.
Attach the bracket, then tighten the screw.
Loosen the nut of the cable grommet, then insert the probe connection
cable and connect it to the electric clamp.
To make the electrical connection between the external probe and
the boiler, refer to the “Electrical wiring” chapter.
Remember to close the cable grommet well, to prevent any air
humidity getting in through the opening.
Put the board back in its seat.
Close the plastic upper protective cover by turning it clockwise.
Tighten the cable grommet very well.

Electrical wiring
The
Family Aqua Condens 3.5 BIS
boiler leaves the factory
completely wired and only need to be connected to the mains power
supply (using the supplied power cable) and the ambient thermostat
(TA) and/or timer, via relevant terminals (fig. 15).
- Set the system's main switch to "off"
- Loosen the fixing screws (
A
) of the connections cover
- Take out the connections cover by pulling it towards you (
B-C
)
- Undo the fixing screws (
D
) of the shell.
- move the housing base forwards and then upwards to unhook it
from the frame
- Lift the control panel and successively turn it forward
- Unscrew the fixing screws of the terminal board covers, then open
them by sliding them in the direction shown by the arrows.
SPECIAL SYSTEMS (fig. 16)
The boiler is able to control an additional circulator connected
hydraulically as shown in the following diagram. This way systems
with outputs above 1.300 l/h can be managed. The additional
circulator is not supplied, but will have to be chosen by the installer
based on the size of the system.
To activate the circulator, set parameter 20, heating mode, to position
03, additional pump (see chapter "Parameter Settings" for further
details).
In these installations, select the maximum fixed speed mode P90 = 1.
Connect the additional pump in the 2-pole terminal board, in the area
rated for V = 230 volts.
In case of power supply between phases, check with a tester
which of the two wires has a greater potential in relation to
the earth and connect it to the L and similarly connect the
remaining wiring to the N.
The boiler can operate with a phase-neutral or phase-phase
supply.
Mandatory items:
- use an omnipolar magnetothermic switch, feeder
disconnector, compliant with CEI-EN 60335-1 standards
(contact opening of at least 3.5mm, category 3)
