大神们! 大金抽真空问题求助!!!

tzs0407

今天家里安装了大金的35机器，也在论坛里做了功课,大体知道抽真空的步骤, 安装工带的是飞跃牌带电磁阀真空泵集成真空表（非压力表）的

那种，正常抽真空15分钟关机负压保压正常，可接下来师傅操作就和论坛里不一样他没进行正压处理而是先拧开液阀（没有开气阀）一小圈

不关闭液阀然后迅速拔掉连接维修口的真空泵软管后再完全打开液阀和气阀，我指出了他的问题 可安装工说这样也可以，他已开液阀，管

路里已是正压后拔的泵管，空气不会回流，而且液阀不关冷媒往外冲比关阀正压效果还要好是双保险这是他多年的经验，我当时想想也对就

没说啥，现在想想有点纠结 求大神指导说明下他这样可不可以！

装了就别纠结了

问题不大，空调没你想象那么脆弱，放宽心，大金空调质量非常好的。

希望没事

已经很不错了,泄露了一点冷媒,三菱电机说明书上要求还是负压拔管呢.

的确是双保险，稍微影响点410的混合比列

飞行眼

这样的操作完全正确。LZ还想哪样？
