5 Turn on the low-pressure valve switch A and the high-pressure valve switch B of the refrigerant recovery and filling machine.打开制冷剂回收加注机低压阀门开关A、高压阀门开关B。 6 Select the "Refrigerant Recovery" option of the refrigerant recovery and filling machine, start the equipment, and start the recovery work.选择制冷剂回收加注机“制冷剂回收”选项，起动设备，开始回收工作。 7 Check the pressure value of the low-pressure gauge of the refrigerant recovery and filling machine. When the pressure gauge reaches -34kPa vacuum, shut down the equipment and stop recycling.查看制冷剂回收加注机低压表压力值，当压力表达到-34kPa真空度时，关闭设备，停止回收。

Recycling compressor lubricating oil回收压缩机润滑油

Caution:注意： ♦  After the refrigerant recovery is completed, the air conditioning compressor lubricating oil is recovered.制冷剂回收完成后，才进行空调压缩机润滑油的回收。 ♦  Recycle and dispose of waste lubricating oil and refrigerants in accordance with relevant regulations.按照相关法规，回收处理废弃润滑油及制冷剂。 ♦  Empty the dispenser oil drain collection bottle.清空加注机排油收集瓶。

1. Operation1. 操作 1 Connect the high and low pressure pipes of the refrigeration circuit to the high and low pressure pipes of the air conditioning system.连接制冷回路高、低压管路到空调系统高低压管路。

2 Turn on the low-pressure valve switch A and the high-pressure valve switch B of the refrigerant recovery and filling machine.打开制冷剂回收加注机低压阀门开关A、高压阀门开关B。 3 Open the oil drain valve on the control panel of the refrigerant recovery and filling machine to start the device and check whether the air conditioning compressor lubricating oil is drained into the collection bottle.在制冷剂回收加注机控制板面上打开排油阀门起动设备，查看空调压缩机润滑油是否排入收集瓶中。 4 After the air conditioning compressor lubricating oil recovery is completed, stop oil discharge and close the oil discharge valve.空调压缩机润滑油回收完成后，停止排油，关闭排油阀。 5 Check the collection bottle and record the amount of oil.检查收集瓶，记录油量。

Fill compressor lubricant加注压缩机润滑油

1. Operation1. 操作   Caution:注意： ♦  Add new lubricating oil according to the amount of lubricating oil in the collection bottle.根据收集瓶内润滑油油量，添加新润滑油。

1 Connect the low-pressure valve switch A and the high-pressure valve switch B, and open the high-pressure valve B of the refrigerant recovery and filling machine and the compressor lubricating oil filling switch.连接低压阀门开关A、高压阀门开关B，打开制冷剂回收加注机高压阀门B及压缩机润滑油加注开关。 2 Start the refrigerant recovery and filling machine and observe the oil level in the filling bottle until the required amount of oil is reached.起动制冷剂回收加注机，观察加注瓶中油面高度，直到所需油量。 3 Close the high pressure valve.关闭高压阀门。

Air conditioning system vacuuming空调系统抽真空

1. Operation1. 操作 1 Connect the high and low pressure pipes of the refrigeration circuit to the high and low pressure pipes of the air conditioning system.连接制冷回路高、低压管路到空调系统高低压管路。

2 Open the high-pressure valve B of the equipment, select the "vacuum" option, and set the time to 15 minutes. Start the refrigerant recovery and filling machine to vacuum. When the time reaches the set value, the equipment automatically stops working.打开设备高压阀门B，选择“抽真空”选项，设定时间为15min。起动制冷剂回收加注机抽真空，时间达到设定值时，设备自动停止工作。   Note:提示： ♦  Only one of low-pressure valve A and high-pressure valve B needs to be opened for vacuuming.低压阀门A、高压阀门B只需开启一个进行抽真空即可。 3 Close the high-pressure valve B of the refrigerant recovery and filling machine and check the pressure value of the low-pressure gauge.关闭制冷剂回收加注机高压阀门B，查看低压表压力值。 4 If the pressure value reaches the set value and does not rise again, it is confirmed that there is no leakage in the refrigeration circuit, and the compressor lubricating oil and refrigerant can be added.若压力值达到设定值，没有重新升高，则确认制冷回路没有泄漏，可以进行压缩机润滑油与制冷剂的添加。 5 If the pressure value rises, check the refrigeration circuit for leaks.若压力值上升，则检查制冷回路是否泄漏。

Add refrigerant加注制冷剂

1. Operation1. 操作 1 Connect the high and low pressure pipes of the refrigeration circuit.连接制冷回路高、低压管。 2 Select the "Refrigerant Replenishment" option of the refrigerant recovery and filling machine and adjust the filling amount.选择制冷剂回收加注机“制冷剂补充”选项，调整加注量。

3 Open the low-pressure valve switch A and start the refrigerant recovery and filling machine for filling.打开低压阀门开关A，起动制冷剂回收加注机进行加注。 Refrigerant model: HFC-134a制冷剂型号：HFC-134a Refrigerant filling amount for heat pump models: 850~950g热泵车型制冷剂加注量：850~950g 4 Observe the display screen of the refrigerant recovery and filling machine. When the filling amount reaches the set value, the screen shows that filling is completed.观察制冷剂回收加注机显示屏，当加注量达到设定值时，屏幕显示加注完成。 5 Close the valve.关闭阀门。 6 Install high and low pressure valve switch sealing covers.安装高、低压阀门开关密封盖。
