4. Setup and Installation
Professional Installation is Mandatory:
The DELLA 2-Zone Mini Split AC Heat Pump system requires professional installation by a qualified HVAC technician. This ensures proper setup, adherence to safety standards, and optimal performance of the unit. Attempting to install the unit yourself may result in damage, improper operation, and will void the product warranty.
Key Installation Considerations:
- Location: Indoor units should be placed to ensure even air distribution. The outdoor unit requires a stable, level surface with adequate airflow.
- Line-Set Connection: The system includes two 16ft copper pipes (standard size 1/4" & 3/8" outer dimension). Line-set vacuuming is required during installation to remove moisture and non-condensable gases.
- Refrigerant Levels: The system is pre-charged. However, any alteration of line-set length requires adjusting freon levels by a certified technician. The system uses R454B refrigerant.
- Drainage: Ensure proper drainage for condensate from the indoor units. The length for the drain pipe is 78.7 inches.
- Electrical Wiring: All electrical connections must be made by a licensed electrician according to local codes and the wiring diagram provided with the unit.
