Unit Assembly; Drilling The Wall - Olimpia splendid Unico Air 20 SF Mode D'emploi Et D'entretien

2.4 - UNIT ASSEMBLY

The maximum length allowed for the pipes is 1 m, the pipes must be internally smooth and no
bends can be made.
It is necessary to use the grilles provided, or grilles which keep the same features.

2.4.1 - Drilling the wall

To operate, the unit requires two holes to be drilled in the wall, positioned as indicated on the drilling template;
the holes must be 162 mm in diameter.
• It is possible to install the unit UNICO PRO INVERTER instead of a unit UNICO SKY or UNICO STAR
or UNICO SMART or UNICO INVERTER 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 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.
• Drill the holes, previously marked, for the wall plugs related to the fixing brackets (fig. 6).
