When installing the unit in a small room,
take measures to keep refrigerant
concentration from exceeding allowable
safety limits in case of refrigerant
leakage.
Refrigerant vapor is heavier than air and
replaces oxygen. Excessive refrigerant in a
closed space can lead to oxygen deficiency,
especially in a small room and a suffocation
hazard could occur.
If equipment utilizing a burner, such as a
cooking stove or a room heater, is used
in the same room as the indoor unit, be
sure to ventilate the room sufficiently to
avoid the danger of oxygen deficiency.
Failure to do so may cause a suffocation
hazard.
Tear apart and throw away plastic
packing bags so that children will not
play with them.
Children playing with plastic bags face the
danger by suffocation.
Do not install the outdoor unit indoor or
in a location into which exhaust gas
could flow.
Make sure that exhaust gas is not being
discharged near an air intake port or
windows where it could be drawn into the
room and cause gas poisoning or
suffocation.
Be sure to ground the unit.
Improper grounding may cause electrical
shock or a fire.
Do not connect the ground wire to utility
pipes, arrester, or ground wires for
electric devices.
A high surge current from lighting or other
sources may cause damage to the air
conditioner.
Do not block the air intake or exhaust
vents of the outdoor unit.
Carbon monoxide produced by the
incomplete combustion may cause gas
poisoning.
Do not install the unit where volatile oil
constituent such as cooking oil or
machine oil suspends in the air.
Doing so may cause the unit to crack, or
may be a cause of electrical shock, a fire or
other hazards.
Do not dismantle, modify or repair the
unit by yourself.
Improper repair and maintenance may
result in water leakage, electrical shock, a
fire or other hazards. Contact your dealer to
perform this work. Only use included
accessories that are specifically designed
for use with the equipment and have them
installed by qualified technician.
Do not install the unit where the smoke
from oil fill, for example, in a kitchen or
where volatile gas, corrosive gas or
metallic dust may beproduced.
Doing so may cause a fire, malfunction or
other hazards.
When any fuel gas leaks from the
outdoor unit, shut off the fuel supply at
the main valve and contact your dealer
immediately.
May cause a fire or an explosion by the
ignition sparks or open flame near by.
When the unit is submerged in water
affected by acts of nature such as floods
or hurricanes, turn off the main power
circuit breaker and contact your dealer.
Operating the unit continuously may cause
malfunction, electrical shock or a fire.
Never use the same pipe for condensa-
tion of water vapor in the exhaust gas
from the outdoor unit and drain water
condensed from the indoor unit.
If exhaust gas enters the building, it could
cause gas poisoning or suffocation.
Always discharge exhaust gas to the
outside of building, so it will not cause
adverse affects in the surrounding area.
If the air intake draws exhaust gas from a
vent or a drainage, it may cause lack of
oxygen and/or carbon poisoning.
Be sure to install the exhaust pipe to
lead exhaust gas to the open air.
In the situation where the exhaust pipe
needs to run through closed drainage/gutter
or into the same location as indoor unit
condensation drainage goes, make sure
that exhaust gas disperses in to the open
air. Failure to do so may lead exhaust gas
into the room, cause lack of oxygen and/or
carbon poisoning.
