This VRF (Variable Refrigerant Flow) Installation Guide provides a structured flowchart outlining the key steps for a successful and systematic VRF air conditioning setup, distinguishing it from conventional split AC systems. The process begins with project confirmation and drawing verification, followed by the installation of indoor and outdoor units, drainage pipes, and ductwork. Critical mechanical steps include pipe laying, welding, flushing, pressure testing, insulation, and creating a vacuum, culminating in charging the system with refrigerant. Simultaneously, electrical wiring is carried out to integrate system controls. The guide emphasizes proper planning and sequencing—such as finalizing pipe sizes and unit placement—before installation begins, ensuring efficiency, safety, and optimal performance of the VRF system.
