5. Installation
Installation of this multi-split air conditioning system requires specialized knowledge and tools. It must be performed by certified HVAC technicians.
5.1 General Guidelines
- Location Selection: Choose a location for the outdoor unit that allows for adequate airflow and is away from direct sunlight or heat sources. Indoor units should be placed to ensure even air distribution.
- Mounting: Securely mount indoor and outdoor units according to the provided installation diagrams.
- Refrigerant Piping: Connect the liquid and gas lines between the outdoor unit and each indoor unit. The system uses R-32 refrigerant, which operates at similar pressures to R410A. Ensure compatibility of tools (manifold gauge, leak detector, recovery unit) with R-32. R-32 is a pure gas, simplifying charging procedures compared to refrigerant mixtures.
- Drainage: Install condensate drain pipes with proper slope to ensure efficient water removal.
- Electrical Wiring: Connect the power supply and communication cables according to the wiring diagram. Ensure all connections are secure and properly insulated.
- Vacuuming and Charging: Evacuate the system to remove non-condensable gases and moisture. Charge with the correct amount of R-32 refrigerant.
For detailed installation steps, refer to the separate Installation Manual provided with the product.
