Having trouble?
Noise is louder than specifications.
Nothing appears in the wireless remote controller display, the display is
faint, or signals are not received by the indoor unit unless the remote con-
troller is close.
The operation lamp near the receiver for the wireless remote controller on
the indoor unit is flashing.
Warm air blows from the indoor unit intermittently when heating mode is off
or during fan mode.

Here is the solution. (Unit is operating normally.)
I The indoor operation sound level is affected by the acoustics of the par-
ticular room as shown in the following table and will be higher than the
noise specification, which was measured in an echo-free room.

I The batteries are low.
Replace the batteries and press the Reset button.
I If nothing appears even after the batteries are replaced, make sure that
the batteries are installed in the correct directions (+, –).
I The self diagnosis function has operated to protect the air conditioner.
I Do not attempt to repair this equipment by yourself.
Turn off the power switch immediately and consult your dealer. Be sure
to provide the dealer with the model name.
I When another indoor unit is operating in heating mode, the control valve
opens and closes occasionally to maintain stability in the air conditioning
system. This operation will stop after a while.
* If this will cause an undesirable rise in the room temperature in small
rooms, etc., stop the operation of the indoor unit temporarily.
