1、想要讓排水管能夠很好的排水，我們就需要注意在安裝排水管的時候，讓排水管能夠有一個輕微的斜坡，這樣電動防火閥就不會出現排水管有可能過高而出現當中央空調停止工作時，內機的水會出現倒流的情況，這樣就會將吊頂泡壞。2、還需要注意的是在安裝排水管的時候要對排水管的外部做一層保溫處理，如果電動防火閥批發不做保溫，那(nei)么就(jiu)會在制冷時間長后，排水(shui)管的(de)(de)表面會出現滴水(shui)的(de)(de)情(qing)況，這(zhe)樣對(dui)吊頂是有著(zhu)一(yi)定的(de)(de)損壞(huai)的(de)(de)。所以要使用(yong)一(yi)些保溫材料，將排水(shui)管的(de)(de)保溫做好。
