The following action should be taken to se-
cure the equipment:
screw the supplied hanging bracket (3)
horizontally to the installation wall. - bracket
with the cut-out facing upwards -. Use suit-
able securing materials (screws, dowels),
according to the type of wall. Using the
horizontal and vertical elongated hole, align-
ment is possible if the fixing hole is out of

the upper vertical recesses of the unit rear
panel.

the securing screw (4).
2.4 Electrical connection
Electrical connection can only be made to an
a.c. 230V ~ 50 Hz supply.
For the purpose of connection, an earthed
socket or unit connection box for permanent
connection should be installed at the side of
the heating unit, at least 10 cm away from it.
In the case of a permanent connection, the
connection cable must not lie against the unit

end sleeves.
