先将暖气片内的空气排出，然后放水排除管道中的杂质和空气。
暖气片整体安装有以下几个细节：
1. 位置选择：选择一个合适的墙面位置安装暖气片，通常选择离窗户较远的墙面，以保证热量能够均匀散布在房间内。
2. 墙面修整：在安装暖气片之前，需要对墙面进行修整，将墙面平整、清洁，并且确保墙面能够承受暖气片的重量。
3. 固定支架：使用支架将暖气片固定在墙面上，确保暖气片稳定牢固。
4. 连接管道：连接管道是暖气片安装中的重要环节，需要将进水管和回水管连接到暖气片上，并且确保连接紧密，不漏水。
5. 排气放水：在启用暖气片之前，需要进行排气放水。先将暖气片内的空气排出，然后放水排除管道中的杂质和空气。
6. 施工清洁：安装完成后，要对安装现场进行清洁，清除施工过程中产生的垃圾和灰尘。
