• 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 tempera-
ture rise of the blown out air. Wait a moment until the airflow comes out naturally.
• The fan is not moving at the set speed.
- In some models, the system switches over to faint airflow when the temper-
ature of the room reaches the set temperature. In other cases, it stops to pre-
vent any cool air from escaping during the defrosting operation.
• 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.
3.3. Fan speed adjustment
To change fan speed
Every time you press the [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 oper-
ation. 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.
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 impor-
tant 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” ventila-
tion 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 begin-
ning of each season.)
• The life of the filter depends on where the unit is installed and how it is oper-
ated.
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.
