14 OWNER'S: PRECAUTIONS FOR SAFETY
WARNING
WARNINGS ABOUT INSTALLATION
Make sure to ask the qualified installation professional in electric work to
install the air conditioner. If the air conditioner is inappropriate installed by
yourself, it may cause water leak, electric shock, fire, and so on.
Be sure to connect earth wire. (grounding work)Incomplete grounding
cause an electric shock. Do not connect ground wires to gas pipes, water
pipes, lightning rods or ground wires for telephone wires.
If you install the indoor unit in a small room, take appropriate measures to
prevent the refrigerant from exceeding the limit concentration even if it
leaks. Consult the dealer from whom you purchased the air conditioner
when you implement the measures. Accumulation of highly-concentrated
refrigerant may cause an oxygen deficiency accident.
Check whether the piping work has been properly completed. When
existing pipes are used and if they are not constructed properly, the
refrigerant gas may leak. Contact the installation company and confirm
that the piping work has been properly completed. For details of
installation of the air conditioner, refer to the Installation Manual. Use
tools and piping materials for R410 only. Failure to do so or improper
installation may cause a burst of pipe, resulting in injury.
WARNINGS ABOUT OPERATION
Cleaning of the air filter and other parts of the discharge lourve involves dangerous work in high places, so be
sure to have a service person do it.
When you notice something abnormal with the air conditioner (smells like scorching, poor heating, etc),
immediately turn off the main switch, the circuit breaker, from the mains to stop the air conditioner, and contact
the dealer.
if the air conditioner is continually operated with something abnormal it may cause machine failure, electric shock,
fire, and so on.
WARNINGS ABOUT MOVEMENT AND REPAIR
When the air conditioner cannot cool or heat a room well, contact the dealer from whom you purchased the air
conditioner as refrigerant leakage is considered as the cause. In the case of repair that requires refill of refrigerant,
ask service personnel about details of the repair. The refrigerant used in the air conditioner is harmless. Generally,
the refrigerant does not leak. However, if the refrigerant leaks in a room and a heater or stove burner in the room
catches fire, it may generate toxic gas. When you ask service personnel for repairing refrigerant leakage, confirm
that the leakage portion has been completely repaired.
Do not move or repair any unit by yourself. Since there is high voltage inside the unit, you may get electric shock
when removing the cover and main unit.
Whenever the air conditioner needs repair, make sure to ask the dealer to do it. If it is repaired imperfectly, it may
cause electric shock or fire.
When moving the air conditioner for re-installing at another place, ask the dealer to do it. If it is imperfectly
installed, it may cause electric shock or fire.

CAUTION
TO DISCONNECT THE APPLIANCE FROM THE MAINS SUPPLY
This appliance must be connected to the mains by means of a switch with a contact separation of at least 3 mm.
The installation fuse 40A, 25A or 16A must be used for the power supply line of this air conditioner.
CAUTIONS ABOUT INSTALLATION (Be sure to confirm the following cautions.)
Use an exclusive power circuit for the air conditioner. Use the rated voltage.
Do not install the unit in a place where inflammable gas may leak. If
inflammable gas accumulates around the unit, it may cause a fire.
CAUTIONS ABOUT OPERATION
Carefully read this manual before starting the air conditioner. There are many
important things to keep in mind for daily operation.
Do not use this air conditioner for special purpose such as preserving food,
precision instruments, art objects, breeding animals, car, vessel, etc.
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.
Do not place any combustion appliance in a place where it is directly exposed to
the wind of air conditioner, otherwise it may cause imperfect combustion.
When the air conditioner is used in a closed room, be careful of sufficient
ventilation of the room. Poor ventilation causes oxygen shortage.
Do not touch any switches with wet finger, otherwise you may get an electric shock.
If the air conditioner won’t be used for a considerably long time, turn off the main switch or the circuit breaker, for
safety.
Do not put anything on the outdoor unit nor step onto it. If so, it may not only topple over the unit, but also injure
yourself.
To make the air conditioner operate in its original performance, operate it within the range of the operating
temperature specified in the instructions. Otherwise it may cause a malfunction, or water leak from the unit.
Prevent any liquid from falling into the remote controller. Do not spill juice, water or any kind of liquid.
15 OWNER'S: REMOTE CONTROLLER INSTRUCTIONS

18 OWNER'S: MAINTENANCE
WARNING
Cleaning of the air filter and other parts of the air filter involves dangerous work in high places, so be sure to
have a service person do it.
Do not attempt it yourself.
Cleaning of air filters
Clogging of air filters will reduce the cooling and heating performance.
(1) When “FILTER ” appears on the remote controller, clean the air filters.
(2) When the cleaning of air filters has been completed, push
button.“FILTER ” disappears.
CAUTION
Cleaning of unit
Clean the unit with a soft dry cloth. If dirt cannot be removed with the dry cloth, use a cloth slightly dampened with
lukewarm (under 40 °C) water.
Cleaning of remote controller
•Use a dry cloth to wipe the remote controller.
•A cloth dampened with cold water may be used on the indoor unit if it is very dirty.
•Never use a damp cloth on the remote controller.
•Do not use a chemically-treated duster for wiping or leave such materials on the unit for long. It may damage or fade the
surface of the unit.
•Do not use benzene, thinner, polishing powder, or similar solvents for
cleaning. These may cause the plastic surface to crack or deform.
Periodic check
Long-period use of the air conditioner may cause deterioration or failure of parts due to heat,
humidity, dust, and operating conditions, or may cause poor drainage of dehumidified water.
If you do not plan to use the unit for more than 1 month
(1) Operate the fan for 1 or 2 hours to dry inside the unit.
Operate “FAN” mode.
(2) Stop the air conditioner and turn off the main power switch or the circuit breaker.
Checks before operation
(1) Check that the air filters are installed.
(2) Check that the air outlet or inlet is not blocked.
(3) Turn on the main power switch or the circuit breaker for the main power supply to the
air conditioner.

NOTE
For environmental conservation, it is strongly recommended that the indoor and outdoor units of the air conditioner in
use be cleaned and maintained regularly to ensure efficient operation of the air conditioner.
When the air conditioner is operated for a long time, periodic maintenance (once a year) is recommended.
Furthermore, regularly check the outdoor unit for rust and scratches, and remove them or apply rustproof treatment, if
necessary.
As a general rule, when an indoor unit is operated for 8 hours or more daily, clean the indoor unit and outdoor unit at
least once every 3 months. Ask a professional for this cleaning/maintenance work.
Such maintenance can extend the life of the product though it involves the owner’s expense.
Failure to clean the indoor and outdoor units regularly will result in poor performance, freezing, water leakage, and
even compressor failure.
