3. സജ്ജീകരണവും ഇൻസ്റ്റാളേഷനും
WARNING: This product operates with high voltage. Installation should only be performed by qualified and experienced technicians to prevent electric shock, injury, or damage to the equipment.
- സുരക്ഷ ആദ്യം: Ensure the air conditioning unit is completely disconnected from the main power supply before beginning any installation. Verify with a voltagഇ ടെസ്റ്റർ.
- നിലവിലുള്ള ബോർഡ് ആക്സസ് ചെയ്യുക: Carefully open the air conditioning unit's housing to gain access to the existing main board.
- പ്രമാണ കണക്ഷനുകൾ: Before disconnecting any wires, take clear photos or make detailed diagrams of all existing connections. Pay close attention to wire colors and pin assignments.
- പഴയ ബോർഡ് വിച്ഛേദിക്കുക: Gently disconnect all wires and connectors from the old main board. Note any specific locking mechanisms on connectors.
- പുതിയ ബോർഡ് ഇൻസ്റ്റാൾ ചെയ്യുക: Position the new Fujitsu main board (Model: 9708016023 K08BH-0903HUE-C) into the designated slot. Ensure it is securely mounted.
- വയറിംഗ് വീണ്ടും ബന്ധിപ്പിക്കുക: Using your documented connections, carefully reconnect all wires and connectors to the new board. Ensure each connection is firm and correctly seated.

- പ്രാരംഭ പവർ-അപ്പ്: After all connections are secure and verified, carefully restore power to the air conditioning unit. Observe for any unusual behavior or error codes.
- പരിശോധന: Perform a full functional test of the air conditioning unit to ensure all modes (cooling, heating, fan, etc.) operate correctly.
4. ഓപ്പറേഷൻ
The main board is the central control unit for your Fujitsu air conditioner. Once correctly installed, its operation is integrated with the air conditioner's existing control system (e.g., remote control, wall thermostat). The board processes commands, manages power distribution to various components (compressor, fans, valves), and monitors system status. No direct user interaction with the board itself is required or recommended during normal operation.

5. പരിപാലനം
The Fujitsu air conditioner main board is a sensitive electronic component and generally requires minimal maintenance. However, to ensure its longevity and reliable performance:
- ഉണക്കി സൂക്ഷിക്കുക: Ensure the air conditioning unit's internal environment remains dry and free from moisture to prevent short circuits or corrosion on the board.
- ശുചിത്വം: Periodically, and only when the unit is completely powered off and disconnected, a qualified technician may gently clean any dust accumulation on the board using compressed air or a soft, dry brush. Avoid using liquids or abrasive cleaners.
- വെൻ്റിലേഷൻ: Ensure proper airflow around the main board within the air conditioner unit to prevent overheating.
- പ്രൊഫഷണൽ പരിശോധന: For any suspected issues or routine checks, consult a professional HVAC technician.
