Caution:注意： |
|
♦
|
Before removing or installing any electrical device, and when exposed electrical pins are easily accessible to tools or equipment, disconnect the negative 12V battery cable to prevent personal injury and vehicle damage.在拆卸或安装任何电气装置前，以及在工具或设备容易接触到裸露的电气针脚时，首先需断开蓄电池负极电缆，以防人员受到伤害及车辆受损。 |
|
♦
|
Do not work in a closed place or near a fire source, and do not weld parts filled with refrigerant.切勿在封闭场所或靠近火源的地方作业，对充注有制冷剂的零部件切勿进行焊接操作。 |
|
♦
|
Always wear goggles when inspecting and repairing refrigeration pipelines, and do not let liquid refrigerant enter your eyes or come into contact with your skin.检查维修制冷管路时需一直佩戴护目镜，切勿让液态制冷剂进入眼睛或接触到皮肤。 |
|
♦
|
If liquid refrigerant enters your eyes or comes into contact with your skin, rinse the contact area with plenty of cold water. In serious cases, seek medical attention immediately.如果液态制冷剂进入眼睛或接触到皮肤则用大量冷水冲洗接触部位，严重时请立即就医。 |
|
♦
|
Be careful when moving system components and do not let system components fall or collide.搬动系统零部件时要小心，切勿让系统零部件掉落、碰撞。 |
|
♦
|
Never turn on the air conditioner when the refrigeration system does not have enough refrigerant.当制冷系统没有足够制冷剂时切勿开启空调制冷。 |
|
♦
|
Never overcharge refrigerant. If the refrigerant is overcharged, it will cause problems such as insufficient heat dissipation and overheating of the compressor.切勿过量充注制冷剂。如果制冷剂被过量充注，会导致散热不足、压缩机过热等问题。 |
|
♦
|
When repairing the refrigeration system, be sure to cover or wrap the disconnected pipe interfaces in time to prevent moisture or impurities in the air from entering.维修制冷系统时，一定要及时对断开的管路接口加盖或包扎密封，防止空气中的水分或杂质进入。 |
|
♦
|
After the air conditioning pipeline is disassembled, the pipeline interface should be sealed or blocked in time to prevent foreign matter from entering.空调管路拆卸后应及时密封或堵塞管路接口，避免异物进入。 |
|
♦
|
The O-ring of the air-conditioning pipeline is a disposable piece, and a new piece needs to be used every time the pipeline is installed or connected.空调管路O型圈为一次性件，每次安装或连接管路时需使用新件。 |
|
♦
|
After replacing the refrigerant, replenish the system with refrigeration oil first, and then refill the refrigerant.更换制冷剂后，要先为系统补充冷冻油，然后再加注制冷剂。 |
|
♦
|
The refrigerant must be discharged slowly to prevent the refrigeration oil from being brought out.制冷剂必须慢慢排放，以免冷冻油被带出。 |
