屋頂風機安裝的基礎須高出屋面,表面要求平整,以防滲水漏水,并須預埋好地腳螺栓。2、風機底座與基礎之間加墊一層5mm橡膠板,以減少振動,地腳螺栓應配有彈簧墊圈,防止使用時松動。3、屋頂風機出口的管徑只能變大、不能變小,最后出風口要安裝防蟲網,偏向上出風時須增加風雨帽;如遇冬季下雪,冰凍日期,必須經常開動,以防大雪堵塞風機出口。4、屋頂風機與(yu)風(feng)(feng)管(guan)(guan)(guan)采用軟管(guan)(guan)(guan)(柔性材(cai)料且(qie)不(bu)燃(ran)燒)連接,長度(du)不(bu)宜(yi)小于(yu)200mm、管(guan)(guan)(guan)徑與(yu)屋(wu)(wu)頂(ding)風(feng)(feng)機(ji)進出口尺寸相同。為保證(zheng)軟管(guan)(guan)(guan)在系統運轉(zhuan)過程中不(bu)出現(xian)扭曲變形(xing),應安(an)裝(zhuang)的松緊適度(du)。對于(yu)裝(zhuang)在屋(wu)(wu)頂(ding)風(feng)(feng)機(ji)吸入端(duan)的帆布軟管(guan)(guan)(guan),可安(an)裝(zhuang)稍緊些,防止屋(wu)(wu)頂(ding)風(feng)(feng)機(ji)運轉(zhuan)時被吸入,減少帆布軟管(guan)(guan)(guan)的截面尺寸
