DESIGN
LK Manifold Shunt Tmax is used in systems with a main pump. The
shunt unit can be mounted directly to LK Manifold RF from the left
or right. The shunt unit is fi tted as standard with a constant
thermostat controlled feed temperature as well as an automatic
speed controlled pump for reduced energy consumption and quieter
operation. The guideline capacity of this shunt unit is
a maximum of 130 m2 fl oor heating surface. The
capacity is dependent on heat requirement, laying
procedure etc.
