Detailed Information

Description

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 fitted 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 floor heating surface. The capacity is dependent on heat requirement, laying procedure etc.

LK 422 can be mounted directly onto the manifold from the right or left. A manifold supply pipe for use when ­mounting to the left of the manifold is supplied. When ­fitting from the right, shorten the supply pipe by about 50 mm, reposition the thermometers and the pump through 180°.

LK 422 requires no maintenance but the installation should be checked regularly.
