Mount with the lowest moving parts at least 2.5 m above the floor or grade

level. (If applicable)



The manufacturer does not assume responsibility for accidents or injury caused by

an incorrectly installed air conditioner. If you are unsure about installation, contact an

installation specialist.



When installing the built-in type air conditioner, keep all electrical cables such as the

power cable and the connection cord in pipe, ducts, cable channels e.t.c to protect

them against liquids, outside impacts and so on.

Deciding on Where to Install the Air Conditioner

When deciding on the location of the air conditioner with the owner, the following restrictions

must be taken into account.

General

PREPARING THE INSTALLATION

Do NOT install the air conditioner in a location where it will come into contact with the following elements:

 Combustible gases

 Saline air

 Machine oil

 Sulphide gas

 Special environmental conditions

If you must install the unit in such conditions, first consult your dealer.

Outdoor Unit

 The outdoor unit must NEVER be placed on its side or upside down, as the compressor lubrication oil will run into

the cooling circuit and seriously damage the unit.

 Choose a location that is dry and sunny, but not exposed to direct sunlight or strong winds.

 Do not block any passageways or thoroughfares.

 Choose a location where the noise of the air conditioner when running and the discharged air do not disturb any

neighbours.

 Choose a position that enables the piping and cables to be easily connected to the indoor unit and the recommend-

ed length of 7.5 metres to be respected. (1 Unit)

 Install the outdoor unit on a flat, stable surface that can support its weight and does not generate any unnecessary

noise and vibration.

 Position the outdoor unit so that the air flow is directed towards the outside, as indicated by the arrows on the top

of the unit.

 Maintain sufficient clearance around the outdoor unit, as indicated in the diagram on the page opposite.

 If the outdoor unit is installed at a height, ensure that its base is firmly fixed in position; the maximum height is

7 metres.

 Make sure that the water dripping from the drain hose runs away correctly and safely.

 You have just purchased a Free Joint Multi air conditioner and it has been installed by your

installation specialist.

 This device must be installed according to the national electrical rules.

 Max input power & current is measured according to IEC standard and input power & current is

measured according to ISO standard.

 More than 2 indoor units should be installed when you use Free Joint Multi air conditioner.
