接触制冷剂会使人受伤。 此系统永远处于加压状态,即便发动机没有工作也是如此。 切勿让已加注制冷剂的系统受热。 接触制冷剂会造成冻伤。 让手、脸避开有助于防止受伤。 制冷管路打开时,须始终佩带护目镜,即便压力计显示系统中已经没有制冷剂,也须佩带。 取下接头时务必小心谨慎。 慢慢地拧松接头。 如果此系统仍然有压力,请抽空系统,回收制冷剂,然后再拆下接头。 通过点燃的香烟吸入制冷剂会导致人身伤害或死亡。 通过点燃的香烟或其他抽烟方法吸入空调制冷气体,或吸入燃烧空调制冷气体形成的烟雾,都会导致人身伤害或死亡。 维修空调时,或在任何可能存在制冷气体的情况下都不要抽烟。 请先将机器移至平坦的地方,然后再对空调和加热系统进行检查。 把所有机具降到地面。 确保变速箱处于空档或停车位置,确保停车制动器接合。 让所有其他人员远离机器。 |
- 回收空调系统中的空调制冷剂。 请参阅维修手册, SENR5664, "使用 R-134a 制冷剂的空调与暖风系统",了解相关正确步骤。 请参阅专门出版物, NEDG5065, "空调工具"了解正确工具信息。
