Unit Assembly; Drilling The Wall - Olimpia splendid Unico R32 EDGE Hinweise Für Die Verwendung Und Pflege

2.4 - UNIT ASSEMBLY

The maximum allowed length of the pipes is 1 m, the pipes must be internally smooth, with a di-
ameter equal to 202 mm or 162 mm 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 or 202 mm) in the wall as indicated in the
drilling template.
The 202-mm holes will ensure best performance and utmost noiselessness.
• It is possible to install the unit UNICO EDGE instead of a unit UNICO SKY or UNICO STAR without
modifying the already existing holes, exception made for the small condensation drain hole.
In this case, in order not to penalize performances, remove the insulating material possibly present in
the air expulsion hole. The anchoring brackets need new drilling too.
• Drill the wall using the proper tools to facilitate your job and prevent excess damage or disturbance to
your client.
The best tools for drilling large holes in walls are special drills called core borers with very high twisting
torque and adjustable rotating speed depending on the diameter of the hole to be drilled.
• To prevent the creation of large amounts of dust and rubble due to drilling, the core borer can be fitted
with a vacuum system applied by means of suction cups to the drilling zone.
• To drill the holes, proceed as follows:
- Place the supplied drill jig (M) against the wall observing the minimum distances from the ceiling,
the floor and from the side walls indicated on the jig itself which can be kept in the correct position
using adhesive tape (Y) (fig. 4).
- Use a small drill or punch to mark, with extreme care, the exact centre of each of the holes to be
drilled (fig.4).
- Using a core boring head measuring at least 202 mm (or 162 mm) 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 (fig. 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.
