Installation

Before installing the appliance

So as not to compromise the normal operation of the module,
the installation site must correspond to the relevant operating
temperature limits and be protected from atmospheric agents. The
module is designed for wall installation, directly under the boiler. It
cannot therefore be installed on a fl oor-standing base or on the fl oor.
When locating the module, provide for suffi cient 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

Position the module using a spirit level. Secure it to the wall using
expansion plugs appropriate for the type of wall and the weight of
the module.

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 fi rst necessary to perform the
following operations:
- thoroughly wash the system tubes in order to remove any swarves,
welding residues or dirt 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 fl ow 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 fi tted;
- make sure the capacity of the expansion vessel is suited to the
amount of water contained in the system.
- When connecting a solar tank, it is requirement to install a non
return valve on the return pipe of direct zone (E)
The module is equipped with a shut-off valve which facilitates
checking and makes it easier to perform any necessary maintenance
procedures.
