Detailed Information

Description

LK 430 is a manifold for 2 - 12 underfloor heating circuits. It is manufactured in stainless steel and is delivered pre-mounted to a bracket. The manifold is equipped with filling / ­drainage valves. The upper manifold marked FLOW is fitted with flow indicators and adjustment valves for setting the ­respective circuit flows. The lower manifold marked RETURN has manually operated valves for shutting off each respective circuit. These valves are normally replaced with thermoelectric actuators. Thermometers for the return and flow manifolds are available - see under Accessories.
LK 430 can also be supplied with an LK 435 OptiFlow ­balancing valve for easy adjustment of the circuit flow. The flow rate is clearly indicated on a transparent scale - see under Accessories. For more information see the product sheet for ­OptiFlow.

The heat supply can be connected to the manifold from the left or the right side. The manifold is delivered ready for connection from the left. When connecting from the right, reposition the drainage valves.

LK 430 requires no maintenance but the installation should be checked regularly.
