If the flammable gas can accumulate around the unit, an
explosion can occur.
The erroneous operation of air conditioner may be
induced by inverter equipment, independent power
device, medical equipment or communication
equipment.
While the erroneous operation of medical equipment or
communication equipment may caused by the air
conditioner.
As the use for the applications other than that
designed originally may result in the deterioration of the
quality. Consult your dealer in this regard.
Installing the unit at the following places may cause a
trouble, a place where much machine oil, salt sonnet,
humidity or dust, spa district, a place full of sulfur gas,
volatile gas, or corrosive gas, a place near high
frequency processing machine.
If the drain pipes are not properly insulated,
condensation will result and drip on ceiling, floor or other
possessions.
When the room humidity exceeds 80% or when the
drain pipe is clogged, water may drip from the indoor
unit. The outdoor unit produces condensation during the
heating operation.
Make sure to provide drainage around the outdoor unit if
such condensation is likely to cause damage.
Improper drain piping may cause water leakage and
damage to furniture or other possessions.
Do not connect the earth wire to gas pipe, city water
pipe, lightning rod or telephone earth wire.
Improper earth connection may cause electrical shock.
Failure to mount the electric leak breaker may cause
electrical shock.
Using a wire or a copper wire instead of proper capacity
of fuse can cause fire or trouble.
Other appliances connected to the same line could cause
an overload.
Otherwise, current leakage, overheating or fire may
occur.
The tighten or loosen the connections may cause generate
heat and cause fire.
The poor mounting of the panel or terminal cover may
cause the heat generation of the terminal connection,
a fire or electrical shock.
Otherwise electrical shock can be resulted.
When carrying in outdoor unit, be sure to support it at
four points.
Carrying in and lifting with 3-point support may make
outdoor unit unstable, resulting in a fall of it.
The unit should not be carried by only one person if it is
more than 20kg.
Some units use PP bands for packing.
Do not use any PP band for delivery purpose.
Do not touch the heat exchanger fins with your bear
hands.
Doing so may cut your hands.
Be sure to safely dispose the packaging materials.
Packaging materials, such as catches and other metal
or wooden parts, may cause stabs or other injuries.
Tear off and discard plastic packing bags so that
children will not play any of them.
If children play with a plastic bag which was not torn off,
it may cause a risk of suffocation.
If such defects are left uncorrected, the unit may fall and
cause personal injury or property damage.
Do not turn the main power switch OFF during seasons
of heavy use, doing so can result In failure.
Touching directly such part can cause a burn or
frostbite as it becomes high or low temperature
according to the refrigerant state.
Touching directly it may injure your hands.
You could be injured if you touch rotating, hot or high-
voltage parts.
Dust may accumulate, and cause a failure.
Continuing the operation without eliminating the
emergency state may cause a machine trouble, fire, or
electrical shock.
Otherwise, water leakage or unit failure may occur.
If washed with water, electrical shock may be caused.
Do not wash the unit with water.
Refrain from installing the unit in an area where
flammable gas can accumulate around the unit.
When the unit is installed at telecommunication
centers or hospitals, take a proper provision
against noise.
For special use as for foods, animals/plants,
precision equipment or art objects, the applicability
should be confirmed beforehand.
Do not use the unit under a special atmosphere.
Thermal insulation of the drain pipes is necessary
prevent dew condensation.
The drain piping must process by surely,and insulate
the drain piping not to be dewy.
Install drain piping according to this Installation
Manual to ensure proper drainage.
Place thermal insulation on the pipes to prevent
condensation.
The unit must be properly earth connected.
When installing at a watery place, provide an
electric leak breaker.
Make sure that there is a main power switch.
Use breaker or fuse with proper capacity.
For the power lines, use standard cables of
sufficient current capacity.
When installing the power lines, do not apply
tension to the cables.
Arrange the configuration of wiring not to bring up
the panel and terminal cover, and fasten the panel
and terminal cover securely.
Do not handle the switch with wet hands.
Be very careful on handling the unit.
The base and attachments of the unit should be
periodically checked for looseness, cracks or other
damage.
Turn on the main power switch more than 6 hours
before starting operation.
Do not touch the compressor or refrigerant piping
without wearing glove on your hands.
Do not touch the metal edges inside the unit
without wearing glove on your hands.
Do not remove the front panel or the fan guard from
the unit when it is running.
Do not operate the air conditioner without the air
filter set place.
At emergency (if you smell something burning), stop
operation and turn the power source switch off.
After stopping operation, be sure to wait for five
minutes before turning off the main power switch.
