Installation Of The Appliance; Hydraulic Connections; Electric Connections - Beretta CONNECT AT Instrucciones Para El Instalador

For your safety, remember that:
The boiler should not be used by children or people that are
unable to use it properly.
It is dangerous to activate devices or electrical equipment
such as switches, domestic appliances, etc. if you smell any
fuel or burning.
Should a gas leak occur, ventilate the room by opening the
doors and windows, shut the main gas valve, call in
professionally qualified personnel from the Technical Assist-
ance service immediately.
Do not touch the boiler when barefoot or when parts of your
body are wet or damp.
Before cleaning, disconnect the boiler from the electricity
mains by switching the bi-pole switch for the plant and the
main switch on the control panel to "OFF".
Any modifications to the safety and regulating devices without
prior authorisation or instructions from the manufacturer are
forbidden.
Do not pull on, disconnect, or twist the electrical cables that
come from the boiler, even when it is disconnected from the
electricity mains.
Do not block up or reduce the size of ventilation openings in
the room in which the unit is installed.
Do not leave containers or inflammable substances in the
room in which the equipment is installed.
Do not leave any part of the packing within reach of children.

INSTALLATION OF THE APPLIANCE

FIG. 1 The Connect AT/BT can be wall-mounted or "built-in", and
can be located near the boiler or at a distance, provided the length
of the plumbing and electrical connections between the boiler and
the Connect AT/BT unit do not exceed 15 metres.
The Connect AT/BT can be installed in positions exposed to the
weather (rain, sun, ice, etc.) only if in "built-in" installation.
Note: The wiring supplied is 2 metres long.
FIG. 2 Wall-mounted installation
When the Connect AT/BT is wall-mounted it must be supported by
two expanding wall anchors (supplied) that are suitable for the
type of wall and weight of the equipment.
We recommend using pipe sleeves built into the wall in order to
limit the infiltration of water.
These pipe sleeves are not supplied with the unit.
Electrical protection level IP10D.
FIG. 3 "Built-in" installation
When the Connect AT/BT unit is built-in:
- Provide the building work, complete with a niche of suitable
size for the Connect AT/BT, to suit the thickness of the wall
(minimum indicative dimensions shown in the figure).
- Position the Connect AT/BT in position, and remember to open
out the two support lugs to fix it more securely.
- Protect the side edges and front while building in the device.
Since the plumbing and electrical connections between the system
and the Connect AT/BT must be contained within the overall size
of the device itself, first position the Connect AT/BT and then the
entry and exit pipes for the system and the conduiting for the electric
cables.
Electrical protection level IPX4D.
FIG. 4 TYPICAL INSTALLATION LAYOUT
The figure alongside shows a possible way of installing the
Connect AT/BT.
NOTE: To allow for installing taps (not supplied) a niche must be
formed of sufficient size to allow them to be fitted below the Connect
AT/BT itself.

HYDRAULIC CONNECTIONS

Before forming the connections all the piping must be thoroughly
flushes to remove any residue that could compromise the proper
functioning of the Connect AT/BT.
FIG. 5
The plumbing connections to the boiler and the system must be
carried out rationally, as indicated in the figure.
Direct connections can be formed using the female couplings on
the delivery and return pipes for the Connect AT/BT, or taps (not
supplied) can be fitted on the lines for shutting off the lines.
These taps are very useful when maintenance is carried out, as
they allow the Connect AT/BT to be drained without having to drain
the entire system.
Check that the expansion vessel on the boiler has suffi-
cient capacity for the size of the system.
FIG. 6
Once the Connect AT/BT has been installed, the 2 ramps supplied
(along with their seals) that interface with the boiler centres must
be fitted inside the Connect AT/BT.

ELECTRIC CONNECTIONS

To form the electrical connections for the Connect AT/BT, access
must be obtained to the Connect AT/BT and the boiler card.
FIG. 7 To gain access to the Connect AT/BT:
- Remove the front cover panel from the Connect AT/BT
If you decide to use cables other than those supplied, cables with
2
a 0,50 mm section must be used. The length of these connections
must not exceed 15 metres.
CONNECTING THE ELECTRONIC SYSTEM CONTROL BOARD
(supplied) TO THE BOILER'S ELECTRONIC BOARD
This connection must be formed using the correct flat cable
(supplied).
The electronic system control board must also be powered by the
mains power supply.
Prevent cables from coming into contact with anti-freeze
resistances.
To form the connection, proceed as follows:
1. Remove the boiler's cover, open the back cover on the control
panel, as shown in the manual for the boiler.
FIG. 8
2. Insert the electronic system control board supplied (C) into its
seating inside the control panel, as shown in figure 2.
FIG. 9
3. Connect the flat cable to the electronic system control board and
the electronic boiler control board (see photo 1 and the wiring
diagram).
FIG. 10
4. To provide power to the electronic system control board, con-
nect the cable's four-pole connector (supplied), as shown in
photo 2
FIG. 11
Pass the wiring harness between the plastic of the instrument
panel and the fuse carrier
FIG. 12
Connect the prods to the mains power supply.
Blue wire - neutral
Brown wire - phase
(see the wiring diagram)
FIG. 13
5. Boilers from inside only: insert the two-pole terminal M2A for the
ambient thermostat below the power supply terminal board in the
boiler's console.
