Unit Assembly; Drilling The Wall - Olimpia splendid UNICO TOWER Instructions Pour L'installation

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 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) in the wall as indicated in the drilling template.
• 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.
• Define where to connect the condensate drain pipe to be used (see paragraph 2.4.2):
- In the fitting under the unit base
- In the fitting inside the unit
• 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 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).
Carefully check the characteristics and consistency of the wall in order to possibly choose wall
plugs specific for particular situations.
The manufacturer will not be held liable for any underestimates made in the
structural consistency of the anchor prepared by the installer.
Therefore, pay utmost attention to the foregoing operation that could cause
serious injury/damage to people/property if carried out incorrectly.
