FHM-CN1 Pre-assembled Mixing Shunt
Product Information
The FHM-CN1 Pre-assembled Mixing Shunt is a component that needs
to be connected to a system according to the provided
illustrations. It comes with pre-mounted union nuts for easy
installation.
Installation Guide
1. Connect the pre-mounted union nut (1) to the primary side
pipe. Tighten the union nut to the control valve with a torque of
at least 85 Nm without any sealing materials.
2. Connect the pre-mounted union nut (2) to the secondary side
pipe or directly on a Danfoss manifold. Tighten the nut to the
mixing shunt with a torque of 15 to 25 Nm using the enclosed rubber
gasket.
3. Mount the FTC thermostatic sensor on the valve following the
enclosed instructions.
Installation Guide Tips
– If the primary side pipe is coming from the bottom, you can
order the bend 4 (088U0821) as an accessory. Tighten the bend to
the mixing shunt with a torque of 30 to 40 Nm.
