This instruction manual is an integral part of the manual for the
boiler to which the Connect AT/BT unit is connected.
See the latter manual for GENERAL WARNINGS and BASIC
SAFETY RULES and other specific information on the func-
tioning of the boiler.
The following symbols are used at some points in the manual:
WARNING
– for actions that call for particular caution
and adequate training.
FORBIDDEN
– for actions that MUST NOT be carried
out under any circumstances
Connect AT/BT conforms to:
●
Low Voltage Directive 73/23/EEC
●
Electromagnetic Compatibility Directive 89/336/EEC
WARNINGS FOR THE USER:
This device does not require any setting or checking by the user.
Opening the front cover on the device is therefore forbidden.
Check the water pressure in the system from time to time. If
necessary, alter the pressure as indicated in the instruction
manual.
If the pressure drops frequently, call in professionally trained
personnel to check the status of your system.

DESCRIPTION OF THE EQUIPMENT
The Connect AT/BT is a water separator that is only to be used with
condensing boilers (type 2005), where it separates the water in
the generator and in the plant, when the latter is characterised by
high flow rates that exceed those developed by the generator
itself. It can also be used to manage mixed low and high tempera-
ture heating systems (radiators / fan coils and radiant panels).
It allow to manage a climatic curve for the high temperature system
and a second for the low temperature system
The Connect AT/BT unit can be built into the wall, thereby avoiding
any protrusion, or it can be wall-mounted.
The unit comes complete with the wiring necessary for connecting
it to the boiler for typical Connect AT/BT installations, near to the
boiler itself (cable length 2 m).
WARNINGS AND SAFETY DEVICES
The boilers made in our factories are all built with care being
taken over each individual component in order to protect both
the user and the installer from any accidents. We therefore
urge trained personnel to be particularly careful with the elec-
trical connections on completion of each job done on the
product, especially as far as the bare parts of the conductors
are concerned. These must not stick out of the terminal board
in any way, so as to avoid any possibility of contact with live
parts of the conductor itself.
Both this instruction manual and the user’s manual are an
integral part of the product. Make sure that they always remain
with the machine, even if it is sold to another owner or user, or
if it is transferred to another plant. If it should get damaged or
lost, ask your local Technical Assistance Service for another
copy.
Installing the boiler and any other assistance and maintenance
work must be carried out by qualified personnel in compliance
with the relevant laws and current standards.
We recommend that the installer instruct the user on how the equip-
ment works and on basic safety standards.
The boiler must only be used for the purposes for which it was
expressly made. The manufacturer does not accept any
contractual or extra-contractual responsibility for any damage
caused to people, animals, or property, due to incorrect
installation, setting, or maintenance, or due to improper use.
On removing thùe packing, check the integrity and complete-
ness of the contents. Should any discrepancies be found,
contact the dealer that sold you the equipment.
The drain from the equipment’s safety valve must be con-
nected to an adequate collection and removal system. The
manufacturer of this equipment is not responsible for any
damage caused by the safety valve opening.
During installation the user must be informed that:
- Should any water flow out, they are to shut off the water
supply and contact the Technical Assistance Service im-
mediately.
- The working pressure for the plumbing system must be
between 1 and 2 bar, and must not exceed 3 bar. Where
necessary, professionally qualified personnel from the
Technical Assistance Service must be called in.
- If the boiler is not to be used for a lengthy period of time,
we recommend calling in the Technical Assistance Serv-
ice to carry out the following operations:
·
Switch the main switch for the equipment and the main
switch for the entire plant to “off”.
·
Close the taps on the water and the fuel supplies, for both
the heating and the hot water systems.
·
Empty the heating and hot water systems if there is any
risk of freezing.
- Maintenance must be carried out on the boiler at least
once a year, and appointments must be made timeously
with the Technical Assistance Service.
