安装步骤
必须按图示要求将 FHM-CN5 连接至系统。
1. 活接弯头（1）在包装内。先将图中所示活接弯头（1）装到一次侧供水管上。再将活接弯头
（1）与活接（2）进行连接，密封材料为活接弯头自带的密封圈，并用30~40 Nm的力矩拧
紧。然后再将活接（2）与三通混水阀进行连接，密封材料为产品附带的密封平垫片，并用
30~40 Nm的力矩拧紧螺母。
2. 将图中所示活接（3）先装到二次侧供回水管上或丹佛斯分集水器上。 再将活接（3）与混水中
心连接，密封材料为产品附带的密封平垫片，并用 30-40 Nm 的力矩拧紧螺母。

小贴士
1. 如果一次侧供回水管是侧进侧出，可将活接弯头
（1）与T型接头（4）连接，密封材料为活接弯头
自带的密封圈，并用30~40Nm的力矩拧紧。
2. 连接螺母（5）在出厂时已拧紧。如果由于在运
输、搬运或类似过程中出现松动而导致泄漏的话，
请用30~40Nm的力矩拧紧。
