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.

I 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
I
the casing may damage electrical wires and consequently cause
fire.
