NOTE

A direct current motor is adopted for indoor fan motor in the Concealed Duct Standard Type air conditioner.

Caused from its characteristics, a current limit works on the direct current motor. When replacing the

high-performance filter or when opening the service board, be sure to stop the fan. If an above action is

executed during the fan operation, the protective control works to stop the unit operation, and the check code

“P12” may be issued. However it is not a trouble. When the desired operation has finished, be sure to reset

the system to clear “P12” error code using the leak breaker of the indoor unit. Then push the operation stop

button of the remote controller to return to the usual operation.
