• Check that the air inlet and outlet are not blocked.
Remove any obstacle.
Obstacles may decrease the airflow rate, leading to
performance decline and breakage of the devices.
Clean the air filter and exterior.
• After cleaning the air filter, make sure to attach it.
(Refer to "MAINTENANCE" on page 10.)
• Turn off the indication "

AIR CONDITIONER
This unit is equipped with a refrigerant leak detector
for safety. To be effective, the unit must be
electrically powered at all times after installation,
other than short service intervals (only for R32
refrigerant).
The following symptoms do not indicate air condi-
tioner malfunction
• HEATING OPERATION within 6 hours after the
power is supplied to the power circuit breaker.
Some models perform the following operation to
protect the devices.
If the HEATING OPERATION is performed within 6
hours after the power is supplied to the power cir-
cuit breaker, the indoor fan stops for about 10 min-
utes during the outdoor unit operation to protect
the devices.
The above operation is performed not only at the
time of installation, but every time the power cir-
cuit breaker is turned on/off.
For comfort heating, it is recommended not to turn
off the power circuit breaker during HEATING
OPERATION.
I. THE SYSTEM DOES NOT OPERATE
• The system does not restart immediately
after the ON/OFF button is pressed.
• The system does not restart immediately
when TEMPERATURE SETTING button is
returned to the former position after pushing
the button.
If the OPERATION lamp lights, the system is in
normal condition.
It does not restart immediately because a safety
device operates to prevent overload of the sys-
tem. After approx. 3 minutes, the system will turn
on again automatically.
• The system does not start when the display
shows "
" and it flashes for few sec-
onds after pressing an operation button.
This is because the system is under centralized
control. Flashes on the display indicates that the
system cannot be controlled by the remote con-
troller.
