你好!!
我想知道是否有人可以帮助我,并解释如何清除制冷电路,我尝试过几次,但我无法正确地做到这一点。
The first thing I do is remove the expansion vessel plug and remove the screw from the thermostatic box, antifreeze filling through the expansion vessel until it comes out to the jet through the hole of the thermostatic box, donkey I put the screw of the thermostatic and filling the maximum the expansion To the thermostat several times and the biggest problem is that there are times that I do not have liquid in the expansion vessel and other times it is up to the expansion vessel, what do I do糟糕吗?或解决方案是什么?
预先感谢和问候
