The Toshiba SHORAI Edge must be installed by an F-Gas certified professional. Installation involves mounting the indoor unit on a secure wall bracket and positioning the outdoor unit in a well-ventilated area. Refrigerant piping (R32) and electrical inter-unit cabling must be connected according to the provided technical manual, ensuring all flare connections are tightened to specified torque settings. The system requires a vacuum purge of the refrigerant lines before opening the service valves to release the pre-charged R32 refrigerant. Electrical supply should be connected to a dedicated circuit with appropriate protection. Upon completion, perform a leak test and verify system operation in both cooling and heating modes. Always refer to the official Toshiba installation manual for specific wiring diagrams, pipe length limitations, and safety protocols regarding R32 handling.
Fixed units must be installed by a qualified F-gas engineer. Find an installer — we'll match you with a local HVAC professional.
