4. Setup and Installation

Installation of a split air conditioning system requires specialized knowledge and tools. It is mandatory that installation, especially the connection and evacuation of refrigerant lines, be performed by a certified HVAC professional.

Installation Steps (Overview for Professional):

1. Site Selection: Choose appropriate locations for both indoor and outdoor units, ensuring proper airflow and drainage.
2. Mounting: Securely mount the indoor unit on the wall and the outdoor unit on a stable surface or wall brackets.
3. Refrigerant Piping: Connect the pre-filled R32 refrigerant lines between the indoor and outdoor units. Ensure proper flaring and tightening to prevent leaks. The unit is pre-filled for approximately 3 meters of line length.
4. Electrical Wiring: Connect the indoor unit to the outdoor unit via an electrical cable. The outdoor unit requires a 230V household power supply.
5. Drainage: Install the condensate drain pipe from the indoor unit to ensure proper water removal.
6. Vacuuming (Evacuation): This critical step involves removing all air and moisture from the refrigerant lines using a vacuum pump. This is essential for the system's efficiency and longevity.
7. Leak Test: Perform a thorough leak test on all connections.
8. Test Run: After installation, perform a test run to ensure all functions operate correctly.

Note: The unit comes with mounting brackets and pre-filled lines for convenience, but professional expertise is still required for safe and effective installation.
