Frischwasser-Modul FriWa für die Trinkwasser-Erwärmung nach ...

Wall-fastening FriWa:
5. Preparation:
Determine the location of the system – near
the buffer storage (max. Tube length on
the primary / heating side = in total
4m!). Copy the hole distances as shown in
the drawing on the right side onto the wall.
6. Mark the holes, drill them and insert the
enclosed wall plugs.
7. Remove the left part of the front insulation.
The station can now be mounted
directly!
8. Establish the system’s tubing according to
the following connexion diagram!
Using galvanized tubes and fittings, it
is important to respect the installation
order in order to avoid any kind of
electrochemical corrosion! The fittings
have been preassambled during the
production, nevertheless, the leak
tightness should be revised (pressure
test) during the commissioning.
