13.2. The following occurrences are not problems or errors

Problem
The fan setting changes during heating.
The fan stops during heating.
When the switch is turned ON, the fan does
not begin to operate.
The outdoor-side fan turns in reverse or stops,
and an unusual sound is heard.
Note:
If indoor-side fan does not operate, check the over-current relay on the fan motor to determine whether it has been tripped.
If the over-current relay has been tripped, reset it after eliminating the cause of the problem (e.g. motor lock).
To reset the over-current relay, open the control box and press the green claw on bottom-right of the relay until a click is heard. Release the claw and check that
it returns to its original position.
Note that if it is pressed too hard it will not return to its original position.

During thermostat OFF mode, light air or low air operation will take place.
During thermostat ON mode, light air or low air will switch automatically to set notch on
the basis of time or piping temperature.
During defrosting, the fan will stop.
After the switch is turned to ON or until the piping temperature reaches 35°C, there will
be 5 minutes of light air operation. After that there will be 2 minutes of low air operation,
then set notch will begin (hot adjustment control).
There is a risk of the power to the unit being connected in reverse phase. Be sure to
check that the phase is correct.
