 When a test run is not
performed properly
• When a test run is not performed properly, refer to
the error code and the part to be checked on
"Troubleshooting".
• When a test run is executed before installing the
external duct, a protection control may be activated
and lets the unit stop and the code P12 may be
displayed. (This is not due to a malfunction but to the
current control function of the DC motor in this unit.)
When a test run executed before installing the
external duct, select "Low" for the fan speed level or
cover the air discharge.
• In addition, stop the operation before replacing the
High-efficiency filter or opening the service panel.
After the test run, reset the circuit breaker of the
