Common questions about manuals, registration, and support for this brand.
Data sheets and technical specifications for discrete IGBT semiconductors and modules are typically available in the product documentation provided with the unit or through the Fuji Electric global technical library online.
For many split-type models, self-diagnosis can be initiated by pressing specific buttons on the remote controller (e.g., holding the 'Set Temperature' buttons simultaneously for 5 seconds). Error codes like 'E:EE' or specific flashes on the indoor unit LED will indicate the issue.
Ensure proper thermal grease application between the module and heat sink to prevent overheating. Regularly check to ensure terminals are not deformed and that the storage environment remains within specified temperature and humidity ranges to prevent corrosion.
Error codes indicate specific faults, such as '01' for communication errors between units, '02' for room temperature sensor issues, or '12' for indoor fan abnormalities. Refer to the specific user manual for your model's full code list.
It is recommended to inspect and clean the air filters regularly (e.g., monthly) to ensure efficient cooling and heating performance and to prevent airflow blockages that could trigger error codes.
