The wall bracket should be used as a template
for fixing the appliance to the wall. It also
helps to keep the necessary ground clearance.
To attach the unit proceed as follows:

I Place the wall bracket ( 5) holding the
centre point horizontally on the ground and
mark the holes
a and d on the assembly
wall;
 II Raise the wall bracket so that the
holes b in the wall bracket coincide with
the marks just made on the assembly wall;
 Mark holes c and d on the wall bracket on
the assembly wall;
 At all four markings drill holes and attach
the wall bracket to the wall using suitable
fixing materials (wall plugs and screws)
dependig on the type of wall. The vertical
slots allow adjustment for an offset in the
fixing holes.
