Abstract
Installation of the cooling system. In cases where the compressor is ordered complete with an OS system, a control unit, a temperature sensor with its connecting wire and an injector (one injector for four-cylinder compressors, two for six-cylinder compressors) are installed on it at the factory. The nozzle is closed with a screw plug. The pulse non-magnetic injection valve, equipped with power supply connectors, is delivered in a separate package to prevent possible damage during transportation. Mount the valve on the compressor before checking the tightness of the circuit.
