Safety Precautions
Ask your original dealer or a professional
for installation work
Installation requires specialised technical expertise.
Attempting to carry out installation on your own and
doing so incorrectly may lead to fire, electric shock,
injury or water leakage.
Use only products specified by your dealer for
options such as humidifiers. Use of other non-
specified products may result in fire, electric shock,
or water leakage. Request an expert to install it.
When installing the unit in a small room, take measures
to assure that the refrigerant concentration limit is not
exceeded even if a leak occurs
Discuss the measures to be taken with the dealer
before installation. There is a risk of oxygen
deficiency if the refrigerant leaks and
concentration limits are exceeded.
Use only products specified by your dealer
Confirm that earthing is performed
correctly
Improper earthing may result in an electric
shock.
Make sure that the drain pipes drain
securely
If the piping is inadequately connected, water
leakages may affect household articles.
Without the leakage breaker, an electric shock may
occur.
Make sure the leakage breaker is securely
attached
Check
the
drainage
Check
the
breaker
Make sure there is no risk of flammable
gas leakage
Gas leaking and accumulating around the unit
may cause a fire.
Confirm that the outdoor unit and the heat
storage unit are fixed on the base
Otherwise, the unit may fall down or other accidents
may occur.

Prohibited
If a problem occurs (such as a burning
smell), stop operation, turn off the power
switch and contact your original retailer
Continuing operation while the problem remains
may cause fire, electric shock or malfunction.
If the air conditioner doesn't cool or heat
up the air, it may be due to a refrigerant
leak, so please contact your original
retailer. If repairs involve refrigerant
recharge check the details of the repairs
with the service person
The refrigerant used in the air conditioner is quite
harmless but if refrigerant does leak and comes into
contact with fire such as a fan heater, stove or
kitchen range, noxious gas may be created.
Compulsory
Turn off
the power
Cautions for use
Do not wash the air conditioner with water
Doing so may result in electric shock.
It may cause incomplete combustion.
Do not place combustion appliances where
is directly exposed to the wind of air
conditioner, otherwise it may cause
imperfect combustion
Check that the mounting base is not
damaged over long periods of use
Leaving the unit on a damaged mounting base
may cause it to fall over and lead to injury.
When the air conditioner is operated with a
combustion appliance in the same place,
be careful of ventilation to let fresh air
enter the room. Poor ventilation causes
oxygen shortage
Inadequate ventilation may cause oxygen
deficiency.
Ventilate
Check the
mounting
base

Safety Precautions (continued)
If water gets inside the unit it will degrade the
electrical insulation and can lead to electric
shocks.
Water droplets may fall from the unit if the air
filter is dirty, the drain outlet is blocked or there is
over 80% humidity.
Doing so may cause a fire or water leakage.
Furthermore, if there is a working power
interruption back up system installed, the fan may
suddenly rotate causing injury.
Falling or something falling down may cause an
injury.
Capacity shortage or incomplete installation may
cause an electric shock or a fire.
Use the rated voltage and a circuit specific to the
air conditioner.
Do not place vases or any other container
holding water onto the unit
Do not place anything which must not
become wet around the indoor unit
Do not use the breaker to start or stop
operations
Do not climb on or place anything on the
indoor or outdoor unit

When cleaning the unit, stop operation
and turn off the power
Use only fuses with the correct capacity
The internal fans rotate very fast and may cause
an injury.
For cleaning please contact your original
retailer
Cleaning the unit incorrectly may lead to the resin
components becoming damaged, or the insulation resistance
of the electrical controls becoming poor which may cause
malfunctions. In the worst cases, it may lead to leakage,
electric shock, smoke generation or fire.
Doing so may adversely affect the plants or animals.
