Drilling The Wall; Assembly Of The Air Ducts And External Grids - Olimpia splendid UNICO EASY S1 Mode D'emploi

2.4 - DRILLING THE WALL

this operation should be carried out using the proper tools to facilitate your work 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 rotation 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.
Our Service Department can give you all necessary information to enable you to find these devices.

2.5 - ASSEMbLY OF THE AIR DUCTS AND EXTERNAL GRIDS

• After drilling the holes (with the core drill), insert the plastic sheet (7) supplied with the air conditioner
(fig. 7) inside them.
The sheets must be 65 mm shorter than the length of the wall.
Roll the sheet (7) and insert it into the hole, paying attention to the splicing line, which must always
•
face upwards. (fig.8).
Use an ordinary cutter for the foregoing operation (fig.8).
to position the external grids, proceed as follows:
a.
Check that the plastic sheet (7) is correctly inserted in the hole.
b. Fix the two flanges (6) using 2 pegs having a diameter of 6 mm and check that the two fixing holes are
horizontal (fig. 9-10-11).
c. Fit the small eyelet of the spring, with the long stem, on the cap pin (on both components) (fig.14).
d. insert the two caps (with spring), on the front part of the external grid, on its two housings, pulling until
it clicks (fig.15) and couple the two chains to the large eyelet of the spring.
e.
using one hand, grip the two chains connected to the grid;
f. Bend the external grids back, gripping them with your free hand where they bend, and insert your fingers
inside the single fins (fig.16).
g. insert your arm into the pipe until the grid protrudes completely outwards.
h. Reopen the grid, being careful to keep your fingers inside the fins.
i.
Turn the grid until the fins are fully horizontal and tilted downwards.
l.
Pull the chain, tensioning the spring, and couple the chain ring to the pin of the inner flange through
which the pipes pass (fig. 17).
m. use hand shears to cut off any excess chain links.
Use exclusively the supplied grids (5), or grids with like characteristics.
