對于HFO-1234yf系統(tǒng)，必須進(jìn)行制冷劑識別。只有當(dāng)
制冷劑高于98%，允許回收。
請注意，在開始此操作之前，清空舊油罐。
執(zhí)行沖洗功能是為了從空調(diào)系統(tǒng)中完全抽出壓縮機(jī)油，從而使污染物

如上所述，制冷劑流量受到限制，沖洗效率可能會受到影響。
對于多流冷凝器，冷凝器中的油可能無法完全沖洗干凈。
請確保設(shè)備中至少有3.5KG制冷劑，否則不允許進(jìn)行沖洗。

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.
