对于HFO-1234yf系统，必须进行制冷剂识别。只有当
制冷剂高于98%，允许回收。
请注意，在开始此操作之前，清空旧油罐。
执行冲洗功能是为了从空调系统中完全抽出压缩机油，从而使污染物
作为酸化物质，水分和其他外来颗粒也会与油一起被提取出来。
冲洗过程中，制冷剂向前流动（将液态制冷剂从空调低压侧加注到
溶解压缩机油，同时从高压侧恢复）和反向（反向
表示从高压侧充电，从低压侧恢复，与正常空调流量相反），每个方向
持续一段时间。冲洗时间可根据系统中的制冷剂量进行设置。对于
例如，使用500g制冷剂的空调系统，建议将冲洗时间设置为30分钟，而60分钟
可为含有1kg或以上制冷剂的系统设置。冲洗制冷剂将被回收和净化
在冲洗过程结束时自动储存在储液罐中，以备再次使用。
对于一些配备蒸发器电磁阀或电子膨胀阀的空调系统，通常
当车辆空调关闭时，建议使用适当的
或使用适当的桥接配件拆下并桥接这些阀门。未执行
如上所述，制冷剂流量受到限制，冲洗效率可能会受到影响。
对于多流冷凝器，冷凝器中的油可能无法完全冲洗干净。
请确保设备中至少有3.5KG制冷剂，否则不允许进行冲洗。
For the HFO-1234yf system, refrigerant identification is necessarily processed. Only when the purity of refrigerant is above 98% the recovery is allowed. Please note, empty used oil vessel before starting this operation. Flushing function is performed to completely extract compressor oil from the A/C system, thus contaminants such as acidified substances, moisture, and other foreign particles will also be extracted together with oil. During the flush, the refrigerant flows in the forward direction (charge liquid refrigerant from A/C low side to dissolve compressor oil, and at the same time recover from the high side) and reverse direction (reverse direction means charge from the high side and recover from the low side, in reverse from normal A/C flow), each direction lasts a certain period of time. Flush time can be set corresponding to the refrigerant amount in the system. For example, A/C system with 500g refrigerant, flush time is recommended to be set at 30 minutes, while 60 minutes can be set for the system with 1kg or more refrigerant. Flushing refrigerant will be recovered and purified automatically, at the end of the flushing process, and stored in the storage cylinder, ready for re-use. For some A/C systems equipped with evaporator solenoids or electronic expansion valves, which are normally closed when the vehicle A/C is off, it is recommended to activate the solenoid and TX valves with the proper diagnostic scanner or remove and bridge these valves with the appropriate bridging fittings. Not performing the above, refrigerant flow is restricted and flushing efficiency can be affected. For a multi-flow condenser, the oil in the condenser may not be flushed out completely. Please make sure at least 3.5KG refrigerant in equipment, or flush is not permitted to run.
