REQUIREMENT
• For the operation procedure, be sure to follow
the Owner’s Manual.
• Finish the forced cooling operation in a short
time because it applies excessive strength to
the air conditioner.
• A test operation of forced heating is

heating operation using the switches of the
remote controller.
However heating operation may be not
carried out according to the temperature
conditions.
• Check wiring/piping of indoor and outdoor
units
1. When pushing [RESET] button for 10
seconds or more, “Pi!” sound is heard and
the operation changes to a forced cooling
operation. After approx. 3 minutes, a
cooling operation starts forcedly.
Check cool air starts blowing. If the
operation does not start, check wiring
again.
