INSTALLATION

When moving the unit while removing it from the carton box, be
sure to lift it by holding on to the four lifting lugs without exerting
any pressure on other parts, especially on the swing flap, the
refrigerant piping, drain piping, and other resin parts.

Leave the unit inside its packaging until you reach the
installation site. Where unpacking is unavoidable, use a sling of
soft material or protective plates together with a rope when
lifting, this to avoid damage or scratches to the unit.

Especially, do not unfasten the packing case (top) guarding the
switch box until suspending the unit.

Refer to the installation manual of the outdoor unit for items not
described in this manual.

Caution concerning refrigerant series R410A:
The connectable outdoor units must be designed exclusively for
R410A.

Do not place objects in direct proximity of the outdoor unit and
do not let leaves and other debris accumulate around the unit.
Leaves are a hotbed for small animals which can enter the unit.
Once in the unit, such animals can cause malfunctions, smoke
or fire when making contact with electrical parts.

Precautions

Do not install or operate the unit in rooms mentioned below.

Places with mineral oil, or filled with oil vapour or spray like in
kitchens. (Plastic parts may deteriorate.)

Where corrosive gas like sulphurous gas exists. (Copper tubing
and brazed spots may corrode.)

Where volatile flammable gas like thinner or gasoline is used.

Where machines generating electromagnetic waves exist.
(Control system may malfunction.)

Where the air contains high levels of salt such as air near the
ocean and where voltage fluctuates a lot (e.g. in factories). Also
in vehicles or vessels.

When selecting the installation site, use the supplied paper
pattern for installation.

Do not install accessories on the casing directly. Drilling holes in the
casing may damage electrical wires and consequently cause fire.

Accessories

Check if the following accessories are included with your unit.

See 

figure 1

Optional accessories

There are two types of remote controllers: wired and wireless.
Select a remote controller according to customers request and
install in an appropriate place.
Refer to catalogues and technical literature for selecting a
suitable remote controller.

A decoration panel is also required for this indoor unit.
