The FHM-CN5 must be connected to a system according to the illustrations.
1. Bend 1 is in package. Install bend 1 to the primary side pipe rstly. And then connect bend 1 and
connector 2 together with torque of 30 to 40 Nm with enclosed O-ring. Finally, connector 2 to 3-way
mixing valve must be tightened with a torque of 15 to 25 Nm with enclosed rubber gasket.
2. Pre-mounted union nut 3 for connection to the secondary side pipe or directly on a Danfoss manifold.
The nut 3 to mixing shunt must be tightened with a torque of 15 to 25 Nm with enclosed rubber
gasket.

Tips
RoHS compliance
1. If the primary side pipe is coming from the side,
the bend 1 must be tightened with T-connec-
tion 4 with a torque of 30 to 40 Nm.
2. Connection 5 are tightened from the factory.
Please double check the connection 5 during
installation. Please tighten at a torque of 15 to
25 Nm if loosening or leaks occur due to trans-
portation or moving.

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橡胶垫片，并用15~25 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橡胶垫片，并用 15~25 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30~40 Nm的
力矩拧紧。
2. 连接件（5）出厂时已拧紧。 请在安装时再
次检查连接件（5），如果发现由于运输或搬
运导致松动或泄漏，请用15-25Nm拧紧。
