Manufacturer instructions

Installation of the Hisense J Series split system must be performed by a licensed professional in compliance with local electrical and F-gas regulations. The indoor unit should be mounted on a structurally sound wall, ensuring adequate clearance for airflow. The outdoor unit requires a level, stable base with sufficient space for heat dissipation. Refrigerant piping must be insulated and connected using flared joints, followed by a vacuum leak test to ensure system integrity. Electrical connections must follow the provided wiring diagram, ensuring proper earthing. Before first power-on, verify all connections, perform a pressure test, and purge the lines. The system should be commissioned by checking operating pressures and ensuring the condensate drain is clear. Always refer to the specific technical manual provided with the unit for precise torque settings and electrical specifications.

Fixed units must be installed by a qualified F-gas engineer. Find an installer — we'll match you with a local HVAC professional.
