2. MAINTENANCE
(FOR SERVICE PERSONNEL)
ONLY A QUALIFIED SERVICE PERSON IS
ALLOWED TO PERFORM MAINTENANCE
WARNING
• Do not use flammable gas (such as hair sprays and
insecticides) near the air conditioner.
• Do not wipe the air conditioner with benzine or thinner.
It may cause cracks, electric shocks or a fire.
• Never put your fingers or rods in the air inlet, air outlet
or horizontal blade. The fan is rotating at high speed, so
you would get injured.
CAUTION
• Do not wash the air conditioner with water.
It may cause electric shocks or a fire due to leakage.
• Make sure to turn off the air conditioner when taking
care of the air conditioner and disconnect the power
supply breaker.
Unless the power supply is disconnected, it may cause
electric shocks and injuries.
• When working at a high place, give caution to your
footing.
If the scaffold is unstable, it may cause injuries due to
fall and stumbling.
NOTE
• Do not remove the air filter except for cleaning.
Operating the unit without an air filter may result in
failure.
• Do not attach substances (such as paper towels)
other than the specified air filter to the air inlet. The
performance may drop and cause freeze-up/water
leakage.
HOW TO CLEAN THE AIR FILTER
When the remote controller indicates “Time to clean filter”,
clean the air filter.
• The indication is made after the system runs for a defined
period of time.
NOTE
• You may change the time of indication “Time to clean filter”.
If the indoor unit is used in a space where the air is
more contaminated, ask your local dealer for solution.
Dust level
Time until indication is displayed
Normal
2500 hours (equivalent to one year)
More contaminated
1250 hours (equivalent to a half year)
• If it becomes difficult to remove dust from the air filter,
replace the air filter.
(The replacement air filter is an optional accessory.)
