ditioner malfunction
•
HEATING OPERATION within 6 hours after the
power is supplied to the air conditioner.
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 air condi-
tioner, the indoor fan stops for about 10 minutes
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 off/on.
For comfort heating, it is recommended not to turn
off the power circuit breaker during the HEATING

diately after the ON/OFF button is pressed.
•
The air conditioner does not restart
immediately when TEMPERATURE SET-
TING button is returned to the former
position after pushing the button.
If the OPERATION lamp lights, the air condi-
tioner is in normal condition.
It does not restart immediately because a
safety device operates to prevent overload of
the air conditioner.
After approx. 3 minutes, the air conditioner
will turn on again automatically.
•
The air conditioner does not start when
the display shows “

flashes for few seconds after pressing an
operation button.

conditioner cannot be controlled by the
remote controller.
•
HEATING OPERATION within 6 hours
after the power is supplied to the air con-
ditioner.

the time of installation, but every time the
power circuit breaker is turned off/on.
For comfortable use, do not turn off the
power circuit breaker during seasonal use of
the HEATING OPERATION.

HEATING OPERATION
(AUTOMATIC HEATING OPERATION):

TION to prevent a decrease in heating
capacity when frost on the outdoor unit
increases.
After maximum 10 minutes, the air condi-
tioner returns to its original operation.
