4. Setup and Installation

Proper installation is crucial for the efficiency and longevity of your DELLA Mini Split AC. This system requires professional installation.

Installation Overview:

Video: This video outlines 5 essential steps to consider before installing your DELLA Mini Split AC unit, covering critical aspects like location, pipe handling, line set bundling, vacuum pumping, and electrical connections.

Video: This video provides a step-by-step guide on how to install your DELLA Mini Split unit, from mounting the indoor unit to connecting the outdoor condenser and performing vacuum tests.

Key Installation Steps:

1. Installation Location:
   • The indoor unit must be at least 6 inches below the ceiling for proper airflow.
   • Verify proper clearances for your model in the user manual's installation preview section.
   • Ensure the wall is sturdy enough to hold the unit's weight without vibration.
   • Keep the inlet and outlet clear of any obstructions.
   • Install the indoor unit 10 feet (3 meters) away from any TVs or radio appliances to prevent interference.
   • The outdoor unit must be spaced away from the wall. Ensure no plants or objects are within 3 feet of the appliance.
2. Refrigerant Pipe Handling:
   • Use a bending tool if available. If not, bend pipes very slowly to avoid damage. Damaged pipes can lead to leaks.
3. Line Set Bundling:
   • After installing the indoor unit, ensure the line set is angled downward and the drain pipe is pointed straight down. This allows proper liquid flow and prevents leaks.
4. Vacuum Pumping the Refrigerant Circuit:
   • This step is critical to remove air and moisture for maximum efficiency.
   • Vacuum for at least 15 minutes for each line set, depending on the strength of your pump.
   • For multi-zone systems, vacuum each line set separately for varying amounts of time depending on length.
   • Use a micron gauge to reach 500 microns. If using a manifold gauge, aim for -30 PSI.
   • Add refrigerant if your line set exceeds 25 feet.
5. Electrical Connection:
   • Ensure safe electrical connection by verifying your home's voltage (115V for this model) and selecting the correct breaker and UL listed wire.
