Warning:
• Do not remove the front panel or the fan guard from the outdoor unit when it
is running. You could be injured if you touch rotating, hot or high-voltage
parts .
• Never insert fingers, sticks etc. into the intakes or outlets, otherwise injury
may result, since the fan inside the unit rotates at high speed. Exercise particular care when children are present.
• If you detect odd smells, stop using the unit, turn off the power switch and
consult your dealer. Otherwise, a breakdown, electric shock or fire may
result.
• When you notice exceptionally abnormal noise or vibration, stop operation,
turn off the power switch, and contact your dealer.
• Do not over-cool. The most suitable inside temperature is one that is within
5 °C of the outside temperature.
• Do not leave handicapped people or infants sitting or standing in the path of
the airflow from the air-conditioner. This could cause health problems.
Caution:
• Do not direct the airflow at plants or caged pets.
• Ventilate the room frequently. If the unit is operated continuously in a closed
room for a long period of time, the air will become stale.
In case of failure
Warning:
• Never remodel the air conditioner. Consult your dealer for any repair or
service. Improper repair work can result in water leakage, electric shock,
fire, etc.
• If the remote controller displays an error indication, the air conditioner does
not run, or there is any abnormality, stop operation and contact your dealer.
Leaving the unit as it is under such conditions can result in fire or failure.
• If the power breaker is frequently activated, get in touch with your dealer.
Leaving it as it is can result in fire or failure.
When the air conditioner is not to be used for a long
time
• If the air conditioner is not to be used for a long time due to a seasonal
change, etc., run it for 4 - 5 hours with the air blowing until the inside is completely dry. Failing to do so can result in the growth of unhygienic,
unhealthy mold in scattered areas throughout the room.
• When it is not to be used for an extended time, keep the [power supply]
turned OFF.
If the power supply is kept on, several watts or several tens of watts will be
wasted. Also, the accumulation of dust, etc., can result in fire.
• Keep the power switched ON for more than 12 hours before starting operation. Do not turn the power supply OFF during seasons of heavy use. Doing
so can result in failure.
1.3. Disposing of the unit
Warning:
If pipes are cut, water may leak and wet the surroundings in the room. When
you need to dispose of the unit, consult your dealer.
2. Names and functions of various parts
Attachment and detachment of filter
[Fig. A] (P.2)
Caution:
• In removing the filter, precautions must be taken to protect your eyes from
dust. Also, if you have to climb up on a stool to do the job, be careful not to
fall.
• Turn off the power supply when the filter is changed.
3. How to operate
• Refer to either Installation Manual or Initial Setting Manual that comes with
the controller to be used.
Caution:
Never expose your body directly to cool air for a long time. Excessive exposure to cool air is bad for your health, and should therefore be avoided.
Dry operation
The dry is a microcomputer-controlled dehumidifying operation which controls
excessive air-cooling according to the room temperature of your choice. (Not usable
for heating.)
Heating operation
3.1. Fan speed adjustment
To change fan speed
Every time you press the 6 [Fan Speed] button once, it switches from the low-speed
to high-speed settings successively.
In the electronics dry operation, the indoor fan automatically turns to low-speed operation. Switching of fan speed is impossible. (Only the display on the remote controller
changes.)
* Every time the fan speed adjustment button is pressed once, the fan speed is
changed.
Fan speed: 3 stages
* This setting can be adjusted only with MA remote controller.
1. Until reaching room temperature of your choice
The compressor and indoor fan function is linked motion according to the
change of the room temperature and automatically repeat ON/OFF.
2. When reaching room temperature of your choice
Both the compressor and indoor fan stop.
When stop continues for 10 minutes, the compressor and indoor fan are operated for 3 minutes to keep the humidity low.
1. When the air-conditioner is used together with burners, thoroughly venti-
late the area. Insufficient ventilation can result in accidents due to oxygen deficiency.
2. Never place a burner at a place where it is exposed to the airflow from the
air-conditioner.
Doing so can result in imperfect combustion of the burner.
3. The microcomputer functions in the following cases:
4. Air does not blow out when heating starts.
- To prevent any cool air from escaping, the indoor fan is gradually switched
in sequence from faint airflow/weak airflow/set airflow according to the
temperature rise of the blown out air. Wait a moment until the airflow
comes out naturally.
5. The fan is not moving at the set speed.
- In some models, the system switches over to faint airflow when the temperature of the room reaches the set temperature. In other cases, it stops
to prevent any cool air from escaping during the defrosting operation.
6. Air flows out even if operation is stopped.
- Approximately 1 minute after the stop of operation, the indoor fan sometimes rotates to eliminate extra heat generated by the electric heater, etc.
The fan speed comes to low or high.

GB
4. The smart way to use
Even minimal steps to care for your air conditioner can help make its use far
more effective in terms of air-conditioning effect, electricity charges, etc.
Set the right room temperature
• In cooling operation, a temperature difference of about 5 °C between indoors and
outdoors is optimum.
• If the room temperature is raised by 1 °C during air-cooling operation, about 10 %
electric power can be saved.
• Excessive cooling is bad for health. It also results in the waste of electric power.
Clean the filter thoroughly
• If the screen of the air filter becomes clogged, the airflow and air-conditioning
effect can be significantly reduced.
Further, if the condition is left unattended, failure can result. It is particularly important to clean the filter at the beginning of the cooling and heating seasons. (When
profuse dust and dirt have accumulated, clean the filter thoroughly.)
Prevent intrusion of heat during air-cooling
• To prevent the intrusion of heat during cooling operation, provide a curtain or a
blind on the window to block out direct sunlight. Also, do not open the entrance or
exit except in cases of dire necessity.
Carry out ventilation sometimes
• Since the air periodically gets dirty in a room that is kept closed for a long time,
ventilation is sometimes necessary. When gas appliances are used together with
the air conditioner, special precautions must be taken. If the “LOSSNAY” ventilation unit developed by our company is used, you can perform ventilation with less
waste. For details on this unit, consult with your dealer.
5. Caring for the machine
Always have filter maintenance performed by a service person.
Before care-taking, turn the power supply OFF.
Caution:
• Before you start cleaning, stop operation and turn OFF the power supply.
Remember that the fan is rotating inside at high speed, posing a serious risk
of injury.
• Indoor units are equipped with filters to remove the dust of sucked-in air.
Clean the filters following the procedures on the right. (The standard filter
should normally be cleaned once a week, and the long-life filter at the beginning of each season.)
• The life of the filter depends on where the unit is installed and how it is operated.
How to clean
• Clear dust away lightly or clean it up with a vacuum cleaner. In the case of severe
staining, wash the filter in lukewarm water mixed with dissolved neutral detergent
or water, and then rinse off the detergent completely. After washing, dry it and fix it
back into place.
Caution:
• Do not dry the filter by exposing it to direct sunlight or warming it using fire,
etc. Doing so can result in the deformation of the filter.
• Washing it in hot water (more than 50 °C) can also result in deformation.
Caution:
Never pour water or flammable sprays onto the air conditioner. Cleaning using
these methods can result in the failure of the air conditioner, electric shock, or
fire.
6. Troubleshooting
Before you ask for repair service, check the following points:
• If operation stops due to a power failure, the [restart-preventing circuit at power failure] operates and disables unit operation even after power restoration. In this case, press
the [ON/OFF] button again and start operation.

does not come out.
The liquid crystal display
shows that it is in operation.
The restart-preventing circuit is in operation for 3 minutes.
Wait for a while.
(To protect the compressor, a 3-minute restart-preventing
circuit is built into the indoor unit. Therefore, there are occasions sometimes when the compressor does not start running immediately. There are cases when it does not run for
as long as 3 minutes.)
Indoor unit operation was restarted during the heating and
defrosting operation.
Wait for a while.
(Heating operation starts after ending defrosting operation.)
It runs briefly, but soon
stops.
The “CHECK” and check

Rerun after cleaning the filter. (Refer to [Caring for the
machine].)
The sound of the
exhaust and rotation of
the motor can still be
heard after stop of running.
All lights are out except
the powered display of
“”.
When other indoor units are engaged in cooling operation,
the machine stops after running a drain-up mechanism for
3 minutes when air-cooling operation is stopped.
Wait for 3 minutes.
The sound of the
exhaust and the rotation of the motor can
be heard intermittently
after stop of running.
All lights are out except
the powered display of
“”.
When other indoor units are engaged in cooling operation,
drained water is brought in. If the drain water is collected,

GB
If malfunctions persist after you have checked the above, turn the power supply OFF and contact your dealer with information about the product name, the nature of the
malfunction, etc. If the display of “[CHECK]” and (4 digit) check code flashes, tell the dealer contents of the display (check code). Never attempt to repair by yourself.
The following symptoms are not air conditioner failures:
• The air blown out from the air conditioner can sometimes give off odors. This is due to cigarette smoke contained in the air of the room, the smell of cosmetics, the walls, furniture, etc., absorbed in the air conditioner.
• The air conditioner sometimes snaps or clicks at the beginning or end of cooling/heating operation. This is the sound of friction on the front panel and other sections due to
expansion and contraction caused by temperature change. This is normal.
• The fan speed changes in spite of not changing the setting. Not to blow out cold air at the beginning of heating operation, the air conditioner automatically adjusts the fan
speed gradually from lower to the set speed. It also adjust its fan speed to protect the fan motor when return air temperature or fan speed excessively rises.
7. Installation, transferring works, and checking
Regarding place for installation
Consult with your dealer for details on installation and transferring the installation.
Caution:
Never install the air conditioner where there is a risk of leakage of flammable
gas.
If gas leaks and accumulates around the unit, fire can result.
Never install the air conditioner at the following place:
• where there is a lot of machine oil
• near the ocean and beach areas where there is salt air.
• where humidity is high
• where there are hot springs nearby
• where there is sulphurous gas
• where there is a high-frequency processing machinery (a high-frequency welder,
etc.)
• where acid solution is frequently used
• where special sprays are frequently used
• Install the indoor unit horizontally. Otherwise, water leakage can result.
• Take sufficient measures against noise when installing the air conditioners at hospitals or communication-related businesses.
If the air conditioner is used in any of the above-mentioned environments, frequent
operational failure can be expected. It is advisable to avoid these types of installation
sites.
For further details, consult with your dealer.
Regarding electrical work
Caution:
• The electrical work must be undertaken by a person who is qualified as an
electrical engineer according to the [technical standard respecting electrical installation], [internal wiring rules], and the installation instruction manual with the absolute use of exclusive circuits. The use of other products
with the power source can result in burnt-out beakers and fuses.
• Never connect the grounding wire to a water pipe, arrester, or telephone
grounding wire. For details, consult with your dealer.
• In some types of installation sites, the installation of an earth leakage
breaker is mandatory. For details, consult with your dealer.
Regarding transfer of installation
• When removing and reinstalling the air conditioner when you enlarge your home,
remodel, or move, consult with your dealer in advance to ascertain the cost of the
professional engineering work required for transferring the installation.
Caution:
When moving or reinstalling the air conditioner, consult with your dealer. Defective installation can result in electric shock, fire, etc.
Regarding noise
• In installing work, choose a place that can fully bear the weight of the air conditioner, and where noise and vibration can be reduced.
• Choose a place where cool or warm air and noise from the outdoor air outlet of the
air conditioner does not inconvenience the neighbors.
• If any alien object is placed near the outdoor air outlet of the air conditioner,
decreased performance and increased noise can result. Avoid placing any obstacles adjacent to the air outlet.
• If the air conditioner produces any abnormal sound, consult with your dealer.
Maintenance and inspection
• If the air conditioner is used throughout several seasons, the insides can get dirty,
reducing the performance.
Depending upon the conditions of usage, foul odors can be generated and drainage can deteriorate due to dust and dirt, etc.
