- Tuberías de refrigerante: Handle refrigerant pipes carefully to avoid damage. Use a bending tool or bend slowly to prevent kinks. Ensure the line set is angled downward from the indoor unit for proper drainage.
- Aspiración del circuito refrigerante: This is a critical step to remove air and moisture for maximum efficiency. Vacuum each line set separately for multi-zone systems. Use a micron gauge to reach 500 microns or a manifold gauge for -30 PSI.
- Conexión eléctrica: Ensure all power sources are turned off before connecting any wires. Connect the ground wire first, followed by the numbered wires (black, white, yellow) to their corresponding terminals on both indoor and outdoor units. Verify your home's voltage (110V or 220V) and use the correct breaker and UL-listed wire for safety.
