WARNING
 The unit should not be installed by the user. Ask the dealer or authorized company
to install the units except room air conditioners for the U.S.A and Canada area.
 If the unit is installed improperly, water leakage, electric shock or fire may
result.
 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.
INSTALLING THE UNIT
 If the power cord of this air conditioner is damaged, it must be replaced by the
manufacturer, its service agent or similarly qualified persons in order to avoid a
hazard.
 The unit must be plugged into an independent circuit if applicable or connect the
power cable to the auxiliary circuit breaker. An all pole disconnection from the
power supply must be incorporated in the fixed wiring with a contact opening of
>3mm.
 Do not use an extension cord with this product.
 If the unit is equipped with a power supply cord and a plug, the plug must be
accessible after installation.
 The air conditioner must be installed in accordance with national wiring regulations

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.
