Safety Precautions
The following safety precautions must be taken when using your air conditioner.
◆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.
WARNING
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 and safety regulations wherever applicable.

Outdoor Unit
◆The outdoor unit must not 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 pipes and cables to be easily connected
to the indoor 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 open
area.
◆Maintain sufficient clearance around the outdoor unit, especially from a radio,
computer, stereo system, etc.
◆If the outdoor unit is installed at a height, ensure that its base is firmly fixed in
position.
◆Make sure that the water dripping from the drain hose runs away correctly
and safely.

The air in the indoor unit and in the pipe must be purged. If air remains in the
refrigeration pipes, it will affect the compressor, reduce to cooling capacity and
could lead to a malfunction. Refrigerant for air purging is not charged in the
outdoor unit. Use Vacuum Pump as shown at the figure.
Connect each assembly pipe to the appropriate valve on the outdoor unit
and tighten the flare nut.

Make sure that you have the required tools available (pipe cutter, reamer,
flaring tool and pipe holder).
If you wish to shorten the pipes, cut it with a pipe cutter, taking care to
ensure that the cut edge remains at a 90°angle with the side of the pipe.
Refer to the illustrations below for examples of edges cut correctly and
incorrectly.

This operation can only be performed by a qualified refrigeration
specialist. For quantity of adding refrigerant, refer to page 19.
Check that the stop valve is closed entirely.

Checking correct grounding
If the power distribution circuit does not have an earth or the ground does
not comply with specifications, an grounding electrode must be installed.
The corresponding accessories are not supplied with the air conditioner.
Select an grounding electrode that complies with the specifications given in
the illustration.
Determine a suitable location for the grounding electrode:
◆
In damp hard soil rather than loose sandy or gravel soil that has a
higher grounding resistance
◆
Away from underground structures or facilities, such as gas pipes,
water pipes, telephone lines and underground cables
◆
At least two metres away from a lightening conductor grounding
electrode and its cable

2
Finish wrapping insulating tape around the rest of the pipes leading to the
outdoor unit.

Install a green/yellow coloured grounding wire:
◆
If the grounding wire is too short, connect an extension lead, in a
mechanical way and wrapping it with insulating tape (do not bury the
connection)
◆
Secure the grounding wire in position with staples
4
Carefully check the installation, by measuring the grounding resistance with
a ground resistance tester. If the resistance is above required level, drive the
electrode deeper into the ground or increase the number of grounding
electrodes.
5
Connect the grounding wire to the electrical component box inside of the
outdoor unit.
