About the pict
ures
:
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 wir
es
tightly. Loose wi
res
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 shou
l
d 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 e
t
c., it was decomposed
and poisonous gas is
will be
generated.
Use only the specified refrigerant to charge the re
f
rigerant
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 cloth
es
away from any moving parts.
Clean up the site after you
've
finish
ed
, 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
Warning
Warning
Caution
Never in
s
tall
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 shou
l
d not
be carried by only one person if it is more than 20kg. It
may
cause the damage of th
e
unit and
personnel injury.
Do not touch the heat exchanger fins w
i
th 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 opera
tion and turn
off
the power
immediately
.
