Connect AT/BT LE conforms to:
Low Voltage Directive 2006/95/EEC
●
Electromagnetic Compatibility Directive 2004/108/EEC
●
This instruction manual is an integral part of the manual for the boiler to which
the Connect AT/BT LE unit is connected.
See the latter manual for GENERAL WARNINGS and BASIC SAFETY RULES
and other specific information on the functioning 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
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.

GENERAL

1.1 Description of the equipment

The Connect AT/BT LE 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 temperature
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 LE unit can be built into the wall, thereby avoiding any pro-
trusion, 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 LE installations, near to the boiler itself (cable length 2 m).

1.2 Warnings and safety devices

The appliances 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 electrical 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.
This instruction manual is an integral part of the product. Make sure that
it always remains 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 appliance 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 equipment
works and on basic safety standards.
The appliance 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 the packing, check the integrity and completeness 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 connected to an ade-
quate 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 immediately;
- the working pressure for the hydraulic 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 appliance is not to be used for a lengthy period of time, we recom-
mend calling in the Technical Assistance Service 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.
