2.4 - UNIT ASSEMBLY
The maximum allowed length of the pipes is 1 m (39”), the pipes must be internally smooth, with
a diameter equal to 202 mm (8”) or 162 mm (6,4”) and bends cannot be performed.
It is necessary to use the grilles provided, or grilles which keep the same features.
2.4.1 - Drilling the wall
Install the unit by drilling two holes,diameter of either 162 mm (6,4”) or 202 mm (8”), in the wall as indicated
in the drilling template.
The 202-mm (8”) holes will ensure best performance and utmost noiselessness.

- Using a core boring head measuring at least 202 mm (8”) or 162 mm (6,4”) to drill the two holes for
entryandexitoftheair.
Drill the foregoing holes tilted slightly downwards to prevent water from being fed back through
the ducts (g. 5).
Most of the removed material is expelled outwards, therefore make sure that it
does not hit any person or object when it falls out.
In order to avoid as much as possible outer plaster breaking, it is necessary to
proceed carefully with the last part of hole execution, decreasing pressure on
core borers.
• Drilltheholes,previouslymarked,forthewallplugsrelatedtothexingbrackets(g.6).
Carefully check the characteristics and consistency of the wall in order to possibly choose wall
plugs specic for particular situations.
