Configurazione e installazione
Proper installation is crucial for the optimal performance and longevity of your DELLA Mini Split AC. It is highly recommended that this system be installed by a qualified professional.
Considerazioni pre-installazione:
- Posizione: Ensure the indoor unit is at least 6 inches below the ceiling for proper airflow. The outdoor unit should be spaced away from the wall, with no plants or objects within 3 feet.
- Wall Strength: Verify the wall is sturdy enough to hold the unit's weight without vibration.
- Liquidazione: Keep the air inlet and outlet clear of any obstructions.
- Interferenza: Install the indoor unit at least 10 feet (3 meters) away from TVs or radio appliances to prevent interference.
- Tubazioni: Handle refrigerant pipes carefully to avoid damage. Bend pipes slowly if a bending tool is not available. Ensure the drain pipe is angled downward for proper liquid flow.
- Aspirazione: Vacuum pumping the refrigerant circuit is critical to remove air and moisture for maximum efficiency. Vacuum for at least 15 minutes per line set. For multi-zone systems, vacuum each line set separately. Aim for 500 microns with a micron gauge or -30 PSI with a manifold gauge.
- Refrigerante: Add refrigerant if the line set exceeds 25 feet.
- Elettrica: Ensure a safe electrical connection. Check your home's voltage (110V or 220V) and select the appropriate UL-listed breaker and wire for the mini split system.
Fasi di installazione:
- Use the provided template to mark locations for the line set wall hole and mini split bracket.
- Use provided screws to drill and securely attach the mini split bracket to the wall.
- Use a leveler to ensure the bracket is properly leveled.
- Run the line set, drain hose, and electrical wires through the wall hole.
- Mount the mini split unit onto the bracket.
- Tape the drain hose and line sets together for a neat and organized installation.
- Use zip ties to secure the electrical wires around the taped line sets and drain hose.
- Set the outdoor condenser in its designated place.
- Remove electrical port and valve covers on the outdoor unit.
- Connect the unit line set to the condenser line set and tighten down securely. Use a digital torque wrench if available to ensure proper tightening.
- Plug in the ground (green) wire first, then continue with the corresponding numbered wires (black, white, and yellow wires are numbered; connect to correlating numbers on the electrical block).
- Ensure the outlet box is powered off before continuing with electrical connections.
- Plug in the ground (green) wire first, then continue with the Leg (black) and Neutral (red) wires on the outdoor condenser.
- Ensure you are using the correct adapter and connect it to the unit.
- Connect the hose from the unit to the gauge.
- Correctly connect the hose from the vacuum to the gauge.
- Open valves on the gauge and turn the vacuum on.
- Pay attention to the micron number; close valves once it reaches 350.
- Spegnere l'aspirapolvere.
- Turn the outlet back on.
- Turn the mini split unit on and set it to the lowest cold setting.
- Wait for the outdoor condenser fan to start (this process could take a few minutes).
- Use a service wrench and slowly open the High Side (Top Valve). Pay attention to the gauge as numbers will drop in the negative when opening the High Side.
- After the High Side has been opened, quickly open the Low Side (Bottom Valve). Pay attention to the gauge as the numbers will spike (This is a Good Thing).
