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.)

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.

under the vane setting icon
This icon will appear when the vane is set
to "Step 5" and the fan operates at low
speed during cooling or dry operation
(depending on the indoor unit model).
The icon will go off in an hour, and the
vane setting will automatically change.
• The actual vane position will differ from the vane position displayed on the LCD
when one of the following conditions is met.
1. While "STAND BY" or "DEFROST" is displayed
2. Immediately after the heating operation
3. During Thermo-OFF in the heating mode
[PFFY-P-VLEM]
While pulling the blowout grill out toward you, raise the rear, remove it, change the
direction, and set it in place.
Caution:
• Avoid putting your hand into the air outlet of the indoor unit any more than
necessary. If you get your hands caught in the metal parts when adjusting
the airflow-direction-adjustment board and blowout grill, or nip them in the
autovane, there is a risk of injury and failure.

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.
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.
• 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.
