Primary return

1. Remove the union nuts 1, 2 and 3 and gasket

5 from mixing shunt which to be used in steps

below, as shown in Fig. 2.

2. Pre-mounted union nut 1 for connection to

the primary side supply pipe . The union nut

1 to control valve 4 must be tightened with a

torque of at least 85 Nm without any sealing

materials, as shown in Fig. 2.

3. Pre-mounted union nuts 2 and 3 for connec-

tion to the secondary side pipe or directly on

a Danfoss manifold. The union nuts 2 and 3 to

mixing shunt must be tightened with a torque

of 30 to 40 Nm with enclosed ﬂat gasket, as

shown in Fig. 2.

4. The end of primary side return pipe E1 for con-

nection to primary side return pipe E.

5. Remove the blue cap 6, as shown in Fig. 2.

6. FTC thermostatic sensor is in package. Mount it

on the valve according to the enclosed instruc-

tion, as shown in Fig. 3.

Tips

Connection 8 and 9 are tightened from the

factory. If leaks occur due to loosening during

transportation, moving or similar, please tighten:

• Connection 8 and 9 at a torque of 30 to 40 Nm.

• Connection 4 and 7 at a torque of min. 85 Nm.

• Connection 7 and 10 at a torque of 30 to 40 Nm

Adjust bypass control valve AVDO to required

diﬀerent pressure according to actual

application, as shown in Fig. 7.

一次侧供水（水平方向）

二次侧供水

二次侧回水

一次侧供水（竖直方向）

一次侧回水

1. 将活接①②③及密封垫片⑤从混水中心拆下备

用，见图 2 。

2. 将图中所示活接①装到一次侧供水管A上。

再将活接①与RA-C控制阀④进行连接，并

用不小于 85 Nm的力矩拧紧螺母，该活接与

RA-C控制阀的连接为硬密封，连接时勿需使

用任何密封材料，见图2。

3. 将图中所示活接②③分别装到二次侧供水管B

和二次侧回水管C上或丹佛斯分集水器上，再

将活接与混水中心连接，密封材料为产品附带

的密封平垫片⑤，并用 30-40 Nm 的力矩拧紧

螺母。见图 2 。

4. 将一次侧回水端E1与一次侧回水管E相连，见

图2。

5. 移除蓝色保护帽⑥，见图2。

6. FTC 恒温阀头在包装内。根据随附说明将其

安装到混水中心上，见图3 。

连接螺母⑧，⑨和活接头⑦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，请参考下述力矩拧紧相关活接及螺母：

· 用30-40 Nm 的力矩拧紧连接螺母⑧，⑨ 。

· 用不小于85 Nm 的力矩拧紧活接头⑦与控制

阀④。

· 用30-40 Nm 的力矩拧紧活接头⑦和一次侧

供水端⑩。

请根据实际应用情况，调节压差旁通阀AVDO到

所需压差，见图 7 。
