NOTE
►
Be sure to align the core drill holes with
a 2° drop from the internal wall to the
external wall. This will allow condensate
in the ventilation pipes to drain to the
outside.
10.3
Drilling holes for dowels and making marks for connecting cables
►
Position the drilling template (item 1 in
Fig. 12) precisely over the two core drill
holes.
►
Mark the four holes (item 2 in Fig. 12) for
the dowels for fixing the ventilation unit to
the internal wall.
►
Mark the position of the passage for the
mains cable (item 4 in Fig. 12) in the
ventilation unit on the internal wall. This
mark identifies the end of the wall channel
that needs to be chased out for the mains
cable.
►
Mark the position of the passage for the
control cable (if used) (item 3 in Fig. 12)
on the internal wall (only for ventilation
units with a control cable connection, see
Table 4 in section 10.8 on page 22). This mark identifies the end of the wall channel that
needs to be chased out for the control cable.
►
Remove the drilling template.
