4. The smart way to use

Even minimal steps to care for your air conditioner can help mak e 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 [9°F] bet een indoors
•
and outdoors is optimum.
• If th e room temperature is raised by 1°C [ 2°F] during air-cooling operation, about
10% electric pow er can be saved.
• Excessive cooling is bad for h ealth . It also results in th e w aste of electric pow er.
Clean the filter thoroughly
If the screen of the air filter becomes clogged, the air o and air-conditioning effect
•
can be significantly reduced.
Furth er, if th e 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

Al ays have filter maintenance performed by a service person. efore care
tak ing, turn the power supply O FF.
Caution:
• B efore you start cleaning, stop operation and turn O FF the power supply.
Remember that the fan is rotating inside at high speed, posing a serious risk
of injury.
Indoor units are equipped ith filters to remove the dust of suc ed in air.
•
Clean the filters follo ing the procedures on the right. (The standard filter
should normally be cleaned once a
beginning of each season.)
The life of the filter depends on

Prevent intrusion of heat during air-cooling
• To prevent th e intrusion of h eat during cooling operation, provide a curtain or a blind
on th e w indow to block out direct sunligh t. Also, do not open th e entrance or exit
except in cases of dire necessity.
Carry out ventilation sometimes
• Since th e air periodically gets dirty in a room th at is kept closed for a long time,
ventilation is sometimes necessary. Wh en gas appliances are used togeth er w ith
th e air conditioner, special precautions must be taken. If th e " LOSSNAY" ventilation
unit developed by our company is used, you can perform ventilation w ith less
w aste. For details on th is unit, consult w ith your dealer.
How to clean
• Clear dust aw ay ligh tly or clean it up w ith a vacuum cleaner. In th e case of severe
staining, ash the filter in luke arm ater mixed ith dissolved neutral detergent
or ater, and then rinse off the detergent completely. After ashing, dry it and fix it
back into place.
Caution:
Do not dry the filter by exposing it to direct sunlight or
•
etc. Doing so can result in the deformation of the filter.
• W ashing it in hot water (more than 50 ° C [122° F]) can also result in
deformation.
Caution:
Never pour ater or flammable sprays onto the air conditioner. Cleaning using
these methods can result in the failure of the air conditioner, electric shock , or
fire.
