Installation Manual

Manifold Mixing Station
172 series
Installation, commissioning and servicing instructions
The 172 series manifold mixing station is designed for use in manifold-based hydronic
distribution systems.The manifold mixing station incorporates a pump and a thermostatic mixing
valve which keeps the flow temperature at a constant set value for use in low temperature
systems such as floor radiant panels. A removable primary circuit hydraulic separator with
check valve is also supplied. The hydraulic separator is essential when there is a primary
circuit circulation pump and when radiator circuits or fan coils are controlled by thermostatic
or thermo-electric valves. When connecting to a Caleffi HYDROLINK
TM
or hydraulic separator
without a primary pump, the hydraulic separator can be removed and the manifold mixing
station can be connected directly. The 172 station, like the TWISTFLOW
TM
Series 668S1
distribution manifolds, can be configured with 3 to 13 circuit outlets offering similar benefits with
built-in sight flow meters/adjustable balancing valves and optional TWISTOP
TM
thermo-electric
zone actuators.
