This manual provides essential instructions for the installation, operation, and maintenance of the Della Mini-Split Air Conditioner. Key procedures include professional installation, proper vacuum pumping of the refrigerant system, and routine filter cleaning. Users should consult the troubleshooting section for error codes before contacting support.
Safety precautions
Installation must be performed by professional or qualified persons. Ensure the mains voltage corresponds to the rating plate. Do not install the unit near flammable substances or in unventilated areas. Always disconnect power before maintenance. Keep the air filter mounted during operation to prevent dust accumulation.
Name of parts
The system consists of an indoor unit and an outdoor unit. The indoor unit features a mounting plate, front panel, emergency button, and air deflectors. The outdoor unit includes the air inlet/outlet, wiring cover, drainage pipe, and refrigerant valves.

Remote control operation
The remote control allows for mode selection (Auto, Cool, Dry, Fan, Heat), fan speed adjustment, and temperature control. Special functions include:
- Turbo: Quick cooling or heating.
- Timer: Automatic on/off scheduling.
- Swing: Adjusts airflow direction.
- Sleep: Adjusts operation for comfort during sleep.
- I Feel: Optimizes temperature based on remote location.
- Anti-Mildew: Dries inner parts after cooling/dry mode.
Installation
Installation involves selecting a location with proper clearances, mounting the indoor plate, drilling the wall hole, connecting refrigerant pipes, drainage hoses, and wiring. The outdoor unit requires a solid base, proper drainage connection, and a vacuum pumping procedure to ensure system integrity. Always perform a test run after installation.





Maintenance
Regular maintenance is required for efficient operation. Clean the air filter frequently to avoid dust buildup. Use a soft, dry cloth or a cloth dipped in neutral detergent to clean the unit surface. Do not use volatile liquids like gasoline or thinner.
Troubleshooting
If the unit fails to operate, check for power failure, blown fuses, or active timer settings. Insufficient airflow may be caused by dirty filters or obstructed vents. The unit displays error codes (e.g., E1, E2, E3) to indicate specific faults like sensor issues or communication errors.
