Before installing the appliance

To prevent improper use of the module, the installation site must
correspond to the relevant operating temperature limits and be
protected from volatile corrosive agents. The module is designed
for wall installation, directly under the boiler. When mounting
the module, provide for sufficient space around it to ensure easy
accessibility after installation.
WARNING
When drilling the wall for installation, take care not to damage
any electrical wiring or existing piping.

Wall installation

Use a spirit level to position the module. To fix it to the wall, remove
the door using the key provided (triangular). Secure the module to
the wall using plugs adapted to the type of wall and the weight of
the device. The four mounting points are located inside the module's
four corners.

Hydraulic connection

The module must be connected to a suitably-sized heating system in
accordance with its performance levels.
Before connecting the module, it is first necessary to perform the
following operations:
- thoroughly flush the system tubes in order to remove any debris
which might prevent the system from operating correctly;
- make sure that the primary circuit pressure does not exceed the
value of 3 bar;
- make sure that the flow temperature is no higher than 85°C;
- make sure that all the necessary safety and operating devices designed to
guarantee the correct operation of the appliance have been fitted;
- make sure the capacity of the expansion vessel is suited to the
amount of water contained in the system.
The module is equipped with an isolation valve which makes it easier
to perform any necessary maintenance procedures.
