2. 故障指示：故障時通用信息和對應的分項信息同時閃爍如表5-2所示
3.顯示面(mian)版的拆卸
在顯示面板的下部一條邊上有兩個缺口將廢鋼鋸條一端磨口井去銳角，用此端插入顯示面板下部一條邊上的缺口處慢慢撬出顯示面板操作時要注意不要將門體的棒層破壞
4.維(wei)修(xiu)時的注意事項
1）此制(zhi)(zhi)冷系統灌注(zhu)為R600a制(zhi)(zhi)冷劑，維(wei)修制(zhi)(zhi)冷系統時一定(ding)要做好安全防火工作(zuo)；系統修好后配(pei)(pei)接毛(mao)細管時一定(ding)按管上做的標記(ji)配(pei)(pei)管，不(bu)能接錯(cuo)，否則會導(dao)致不(bu)制(zhi)(zhi)冷、不(bu)停機
2）此系統用(yong)的(de)脈(mo)沖閥施加的(de)電流(liu)為半波脈(mo)沖，所(suo)以不能直接用(yong)施加220V電壓(ya)的(de)方法(fa)試脈(mo)沖閥是否(fou)正確工作(zuo)
