Hydraulic Connections; Electric Connections; Installation Of The Appliance - Beretta CONNECT MIX STAND ALONE Instrucciones Para El Instalador Y El Servicio De Asistencia Técnica

For your safety, remember that:
The boiler should not be used by children or people that are
unable to use it proper ly.
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 b y opening the
doors and windows, shut the main gas valve, call in
professionally qualified personnel from the Technical Assist-
ance ser vice 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 MIX STAND ALONE 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 MIX ST AND ALONE unit do
not exceed 15 metres.
The Connect MIX STAND ALONE can be installed in positions
exposed to the weather (rain, sun, ice, etc.) only if in "built-in"
installation.
FIG. 2 Wall-mounted installation
When the Connect MIX ST AND ALONE 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 le vel IP10D.
FIG. 3 "Built-in" installation
When the Connect MIX STAND ALONEV unit is built-in:
- Provide the building work, complete with a niche of suitable
size for the Connect MIX ST AND ALONE, to suit the thic kness of
the wall (minimum indicative dimensions shown in the figure).
- Position the Connect MIX ST AND ALONE in position, and
remember to open out the tw o 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 MIX ST AND ALONE m ust be contained within
the overall size of the device itself, first position the Connect MIX
STAND ALONE and then the entr y and e xit pipes f or the system
and the conduiting for the electric cables.
Electrical protection le vel IPX4D.
TYPICAL INSTALLATION LAYOUT
FIG. 4
The figure alongside shows a possible way of installing the
Connect MIX STAND ALONE.
NOTE: To allow for installing taps (not supplied) a niche m ust be
formed of sufficient size to allow them to be fitted below the Connect
MIX STAND ALONE 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 MIX STAND ALONE.
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 retur n pipes f or the Connect MIX STAND ALONE, 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 MIX STAND ALONE 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 MIX ST AND ALONE has been installed, the 2
ramps supplied (along with their seals) that interface with the boiler
centres must be fitted inside the Connect MIX STAND ALONE.

ELECTRIC CONNECTIONS

To f orm the electr ical connections f or the Connect MIX STAND
ALONE, access m ust be obtained to the Connect MIX ST AND
ALONE and the boiler card.
FIG. 7 To gain access:
- Remove the front cover panel
CONNECTING THE CONNECT MIX ST AND ALONE TO THE
ELECTRICITY MAINS
Connect MIX STAND ALONE unit to the electricity mains (phase /
neutral / earth) using the cable supplied.
Drawing the power supply for the Connect MIX STAND ALO-
NE from theboiler is absolutely forbidden as the boiler's fuse
is not sizedto take the electrical loads associated with the
Connect MIX STAND ALONE.
FIG. 8
CONNECTING THE AMBIENT THERMOSTATS (TA)
The TAs for the lo w (TA2+) and high (T A1+) temperature system
must be directly connected to the Connect MIX ST AND ALONE
using a cable with minimum section 1 mm
FIG. 9
BAG MIX CLIMA CONNECTION TO THE BOILER
2
Connect the TA from the BAG2 MIX BASIC Board to the heater TA
cable grip using the cable provided (refer to the wiring diagram in
the installer instruction booklet for the specific heater).
When using a phase-phase pow er supply, use a tester to deter-
mine which of the two wires has the greater potential compared to
the earth and connect it to the L terminal. Connect the remaining
wire to the N terminal.
For floating power supplies, that is, those that have no earth con-
nection, an insulation transformer must be used, with a secondary
unit connected to the earth.
The following are obligatory:
- A multi-pole trip-switch must be used to disconnect the line, that
conforms to the CEI-EN 60335-1 standards (contact opening at
least 3,5mm, category III).
- Use cables with a 1,5 mm
N (Neutral) connection.
- The amper age on the s witch m ust be adequate f or the boiler' s
electrical power rating – see the technical data to check the elec-
trical power rating for the model installed.
- Connect the equipment to an efficient earthing system.
- The power socket must be inaccessib le after installation.
The use of gas or water pipes to earth this equipment is forbidden.
The manufacturer does not accept any responsibility for any dam-
age caused due to the lack of a proper earth or failure to comply
with the wiring diagram.
