Manufacturer instructions
The Panasonic CU-4Z80TBE is a professional-grade multi-split outdoor unit designed for connection to up to four indoor units. Installation must be performed by a qualified technician in accordance with local F-gas regulations, as the system uses R32 refrigerant. The unit requires a 230V, 50Hz single-phase power supply, which is connected directly to the outdoor unit. Mounting should be on a stable, level surface with adequate clearance for airflow as specified in the technical manual. Refrigerant piping must be vacuum-purged and leak-tested before opening the service valves. Electrical connections must follow the provided wiring diagrams, ensuring proper communication cabling between the outdoor and indoor units. Upon completion, perform a test run to verify system operation and check for any refrigerant leaks or abnormal vibrations before final handover.
Fixed units must be installed by a qualified F-gas engineer. Find an installer — we'll match you with a local HVAC professional.
