Use the key “1” for the orientation of the in-
terface panel as described in par 2.2.2. If the
key is lost or damaged, the operation can be
done using a standard 2mm allen wrench.
Once the 2 plastic keys have been separat-
ed they can be used by inserting “2” in one
of the holes “B” in key “3”: whichever hole is
most convenient, depending on the opera-
tion. At this point you obtain a multifunction
cross key, with a use corresponding to each
of the 4 ends.

To use the cross key you must put the unused key “1” away in a
safe place so that it does not get lost, or else put it back in its seat
inside key “3” at the end of operations.
Use of end “C”:
this is practically a straight tip screwdriver of the correct size for manoeu-
vring the caps of the main connections of the system (1” and 1”1/4). To
be used at the rst installation to remove the caps from the mouths on
which you want to connect the
system; for the lling operation in
the case of horizontal installation;
to access the non-return valve,
… If the key is lost or damaged,
the same operations can be per-
formed using a straight tip screw-
driver of a suitable size.
Use of end “D”:
hexagonal socket head suitable for re-
moving the cap to perform lling in the
case of vertical installation. If the key is
lost or damaged, the same.
