Installation involves mounting the indoor unit on a secure, level wall surface using the provided mounting plate, ensuring adequate clearance for airflow. The outdoor unit must be placed in a well-ventilated area, clear of obstructions. Refrigerant piping and electrical wiring between units must be connected by a certified technician, ensuring all joints are leak-tested and the system is properly evacuated before opening the service valves. Electrical connections must adhere to local safety standards. Upon completion, perform a system test run to verify cooling, heating, and airflow functions. Users should refer to the official Hisense HVAC technical documentation for specific torque settings, wiring diagrams, and maintenance schedules to ensure optimal performance and safety.
