3. Setup & Installation

Proper installation is crucial for the optimal performance and longevity of your DELLA Mini Split AC. It is strongly recommended that installation be performed by a qualified HVAC professional.

Pre-Installation Considerations:

Before beginning installation, review these critical steps to ensure proper setup:

Video Description: This video outlines 5 urgent steps to consider before installing your Della Mini Split AC. It covers critical aspects like choosing the correct installation location for both indoor and outdoor units, proper handling of refrigerant pipes to prevent damage, correctly bundling the line set for efficient drainage, the importance of vacuum pumping the refrigerant circuit to remove air and moisture, and ensuring a safe electrical connection with the correct voltage and UL-listed wiring.

• Installation Location: The indoor unit must be at least 6 inches below the ceiling for proper airflow. Verify proper clearances in the user manual's installation preview section. Ensure the wall is sturdy enough to hold the unit's weight without vibration. Keep inlet and outlet clear of obstructions.
• Refrigerant Pipes: Handle with care. Use a bending tool if possible, or bend slowly to avoid damage. Damaged pipes can lead to leaks.
• Line Set Bundling: After installing the indoor unit, ensure the line set is angled downward and the drain pipe points straight down to allow proper liquid flow and prevent leaks.
• Vacuum Pumping: This is a critical step 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.
• Electrical Connection: Always verify your connection for safety. Check your home's voltage (110V or 220V) and select the appropriate breaker size and UL-listed wire for the mini split system.
