CHAP. 2 INSTALLATION
CHAP. 2.1 INSTRUCTIONS FOR INSTALLATION
To obtain the best results and optimum performance, follow
the instructions for correct installation provided in this
manual. Failure to follow the instructions and apply the
rules indicated may cause malfunction of the appliance and
relieves the manufacturer of any form of guarantee and
liability for damages to persons, animals or property.
The electrical system must comply with the regulations
and rating data in the technical sheet, with good
grounding.
SELECTION OFPOSITION OFTHE UNIT
The position for installation of the inside unit, to obtain the best
performance and prevent breakdowns or hazards, must have the
following requisites:
-The bottom of the low level unit must be at least 300mm off the
floor whilst the high level unit must be at least 2 meters off the
floor and no more than 3 (fig. 1)
-The wall on which the inside unit is installed must be
sturdy and able to withstand its weight.
-There should be no obstacles to the free circulation of air on the
intake side andon the air outlet side especially, there should
be no obstacles closer than 2 m (this could cause turbulence that
would interfere withcorrect operation of the unit).
-It must be possible to leave room around the unit for any
maintenance operations that may be necessary.
The air conditioner must be installed on a wall that
communicates with the outside.
Caution: After determining the best place for installation
as described above, check to make sure that the wall can
be drilled in that point without interfering with other
structures or installations (beams, piers, pipes, wires,
etc.). Check again to make sure there are no obstacles
to air circulation through the holes to be drilled due to
plants and their leaves, slats or paneling, blinds,
gratings or grids too dense, etc.).
Before installing the air conditioner, it is essential to make an
accurate calculation of the heat load in summer (and cold
load in winter for models with heating pump) at the site of
installation.
The more accurate this calculation is made the better the air
conditioner will be able to do its job.
To make these calculations, refer directly to the regulations in
effect (UNI ref.Law 10/91) or tothe tables, both printed and
computerized, based on those regulations. For particularly
significant applications, we recommend contacting expert
heating engineers.

2.2.2
Dimensions and
features of site
where air
conditioner is
installed

As far as possible, in any case, it is important to try and reduce major
thermal loads by the following means: Large glass panes exposed to
sunlight should be provided with curtains on the inside or shades on
the outside (Venetian blinds, verandas, refracting films, etc.) The air-
conditioned room should be closed as much of the time as
possible.
Halogen spotlights or other electrical equipment with high power
consumption should not be used in the room (toasters, steam irons,
hot plates for cooking, etc.).
-It should not be installed in a position where the air flow can strike the
people underneath directly (fig. 2).
-It should not be directly over another appliance (television set,
radio, refrigerator, etc.), or over a source of heat (fig. 3).
-There should be no obstacles for reception of signals emitted by the
remote control (fig. 4).
CHAP. 2.3 INSTALLATION OF THE UNIT
2.3.1 This operation should be carried out using the proper tools
Drilling the wall 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.
Compact Solutions would be able to assist you in locating these
devices.
To drill the holes, proceed as follows:
Fasten the drilling template to the wall leaving the necessary space
from the ceiling, floor and side walls as shown on the template. Use
adhesive tape to fasten it in place.
Use a small drill or punch to mark, with extreme care, the exact centre of
each of the holes to be drilled.
Usinga core boring head measuring at least 158mm to drill the two holes
for entry and exit of the air.
Note: The holes should have a slight outward inclination to
prevent any backflow of water from the pipes (see fig.1).
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.
Fig 5

Next, drill the holes for anchoring the fastening brackets to the wall
using as a first option the 4 holes on the ends of the bracket as
shown on the drilling template (see fig. 6).
If the wall is not very solid, it is advisable to use some extra
anchor bolts.
As you can see, the bracket can be fastened in a number of
different ways and positions. The air conditioner is heavier
on the left-hand side, so it is best to make sure of a solid
anchorage on that side. The anchor bolts provided require holes
with a diameter of 10 mm. In any case, the wall should be
inspected carefully to determine the best possible anchorage and
type of bolts suitable for particular situations.
Warning: The manufacturer is not liable in case of
underestimation of the structural consistency of the
anchorage made at the time of installation. We
therefore recommend that you perform this operation with
the maximum care as, if not done properly, it can cause
serious damage to persons and property.
When installing models equipped with heating pump, if no
drainage well for condensate has been provided built into the
wall (see paragraph 2.3.2), it will be necessary, to allow for
drainage of the condensate, to drill a hole through the wall
measuring 16 mm in diameter in the position shown on the
template (see fig.6).
