About the pictures:
Erroneous handing gives a high possi-
bility to induce serious results such as
death or heavy injury.
Erroneous handing may induce serious
injury depending on the situation.
Do not supply power to the unit until all wiring and tubing
are completed or reconnected and checked.
Highly dangerous electrical voltages are used in this
system. Carefully refer to the wiring diagram and these
instructions when wiring. Improper connections and inad-
equate grounding can cause accidental injury or death.
Ground the unit by following local electrical codes.
Connect all wires tightly. Loose wires may cause over-
heating at connection points and a possible fire hazard.
All electric work must be performed by licensed technician ac-
cording to local regulations and the instructions given in this
manual.
There is risk of fire, electric shock, explosion or injury.
Ask your dealer or specialized subcontractor for installation or
repair work.
Make sure that the ceiling/wall is strong enough to hold the
unit’s weight. The outdoor unit should be installed in a
location where air and noise emitted by the unit will not
disturb the neighbors.
Properly insulate any tubing run inside a room to prevent
"sweating" that can cause dripping and the water may
damage walls and floors.
The outdoor unit must be installed on stable, level surface and
the place where there is no accumulation of snow, leaves
or rubbish.
The unit should be installed according to the instructions
in order to minimize the risk of damage from earthquake,
typhoon or strong wind.
When the refrigerant touches the fire etc., it was decomposed
and poisonous gas is will be generated.
Use only the specified refrigerant to charge the refrigerant
circuit.
Do not mix it with any other refrigerant and do not allow air to
remain in the circuit.
Air enclosed in the circuit can cause high pressure and result
in a rupture and other hazards.
After completing installation work, make sure that refriger-
ant gas has not leaked.
The limit density can not be exceeded even if the refrig-
erant leaks by any chance.
Turn the power off at the main power box (mains) before open-
ing the unit to check or repair electrical parts and wiring.
Keep your fingers and clothes away from any moving parts.
Clean up the site after you've finished, remember to check that
no metal scraps or bits of wiring have been left inside the unit
being serviced.
The unit must be properly earth connected.

Caution
Never install the unit at the place where a combustible gas might
leak. The gas may ignite or explode when the gas leaks and
collects in surround of the unit.
When the unit is installed at telecommunication centers or
hospitals, take a proper provision against noise.
When installing the unit at a watery place, provide an electric
leak breaker.
Do not wash the unit with water.
Be very careful about unit transportation. The unit should not
be carried by only one person if it is more than 20kg. It may
cause the damage of theunit and personnel injury.
Do not touch the heat exchanger fins with your hands, otherwise
your hands may be hurt.
Do not touch the compressor or refrigerant piping without
wearing glove on your hands. Touching directly such part can
cause a burn or frostbite as it becomes high or low temperature
according to the refrigerant state.
Do not operate the air conditioner without the air filter set
place. Dust may accumulate and a failure may be incurred.
At emergency status(if you smell something burning), stop
the operation and turn off the power immediately.
