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).
