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