Overview
6.2. Hot water connection
Do not connect the hot water connection directly to the copper pipes. It must be equipped with a
dielectric connection (supplied with the appliance).
In case of corrosion of the threads of the hot water connection not equipped with this protection,
our warranty will not apply.
If you are using synthetic pipes (e.g.: PEX, multi-layer, etc.), the installation of a thermostatic
regulator at the outlet of the water heater is mandatory. It must be adjusted according to the
performance of the material used.
6.3. Connection of the recirculation system
Do not connect the recirculation system directly to the copper pipes. It must be equipped with a
dielectric connection (not supplied with the appliance).
In case of corrosion of the threads of the recirculation system not equipped with this protection, our
warranty will not apply.
If you are not using a recirculation system, a "plug + seal" unit must be connected to this tap point
(supplied with the appliance).
6.4. Primary circuit connection (for products with internal heat exchanger)
Protect against excessive pressure caused by the expansion of the water when heated by a 0.3 MPa
(3 bar) valve, or by an open-type expansion tank (at atmospheric pressure) or by a closed membrane
tank. The operating pressure of the heat exchanger circuit must not exceed 0.3 MPa (3 bar) and its
temperature must not exceed 85°C. In the case of connection to solar collectors it is necessary to
apply a glycol mixture for frost protection and anti corrosion: such as "TYFOCOR L". If the installation
includes a stop valve at the inlet and outlet of the exchanger, never close the two valves
simultaneously in order to avoid the risk of the coil breaking.
Preparation of the circuit
For any installation (new or upgraded), a thorough cleaning of the water network's pipelines should be
carried out. The purpose of this cleaning prior to commissioning is to eliminate germs and residue that could
lead to the formation of deposits. In particular, in a new installation, grease, rusted metal or else micro-
deposits of copper have to be removed. As for installations that are being upgraded, the cleaning is intended
to remove sludge and the products of corrosion formed during the previous period of operation.
There are two types of cleaning/desludging: a rapid approach that is completed within a few hours and a
more gradual approach that can take several weeks. In the first case, it is imperative to carry out this cleaning
operation before the new boiler is connected. In the second case, placing a filter on the boiler's return pipe
will allow the loosened deposits to be collected.
Cleaning prior to commissioning the installation contributes to an improvement of the installation's efficiency,
a reduction of its energy consumption and the prevention of scale formation and corrosion. This operation
requires the intervention of a (water treatment) professional.
