WARNING
Be sure to provide for adequate measures in order to
prevent that the unit be used as a shelter by small
animals.
Small animals making contact with electrical parts can
cause malfunctions, smoke or fire. Please instruct the
customer to keep the area around the unit clean and

consideration
earthquakes.
Improper installation work may result in accidents due
to fall of equipment.
The equipment is not intended for use in a potentially
explosive atmosphere.
Be sure that sufficient precautions are taken, in
accordance with the applicable legislation, in case of
refrigerant leakage.
CAUTION
Do not install the unit in places such as the following:
Where there is mist of mineral oil, oil spray or vapour.
Plastic parts may deteriorate, and cause them to fall
out or water to leak.
Where corrosive gas, such as sulphurous acid gas, is
produced.
Corrosion of copper pipes or soldered parts may
cause the refrigerant to leak.
Where there
electromagnetic waves.
Electromagnetic waves may disturb the control
system, and cause malfunction of the equipment.
Where flammable gases may leak, where carbon fibre
or ignitable dust is suspended in the air or where
volatile flammables, such as thinner or gasoline, are
handled.
Such gases may cause a fire.
Where the air contains high levels of salt such as that
near the ocean.
Where voltage fluctuates a lot, such as that in
factories.
In vehicles or vessels.
Where acidic or alkaline vapour is present.
Install the unit, power wire and connecting wire at
least 1 meter away from televisions or radios to
prevent image interference or noise.
(Depending on the radio waves, a distance of 1 meter
may not be sufficient to eliminate the noise.)
