LK Manifold RF 1-12 circuits

LK Manifold RF is made of stainless steel, the variants having 1 to 12 floor heating circuits. The manifold is delivered pre-mounted in brackets. The manifold has thermometers on the supply and return, manual air-bleed valves and filling/drain valves*.
(*Manifold RF 1 is supplied without thermometer or filling/drain valve)

The upper manifold marked FLOW (supply) is fitted with flow indicators graded from 0,5-5 l/min and adjustment valves for the adjustment of individual circuit flows. The flow indicators are made of temperature and impact resistant plastic. The plastic is resistant to anti-freeze, as well as glycol and ethanol with up to 50% respective 30% mix.

The lower manifold marked RETURN has hand actuators for shutting off individual circuits. The hand actuators are normally replaced with LK Actuator.

Primary flow and return can be connected from the left or right-hand sides. The manifold is ready to be connected to the left-hand side on delivery. Connection from the right is done by removing the end cap assemblies. Connection dimension 1" female thread.

Marking plates for identifying individual floor heating circuits, assembly instructions and a protective bag used to protect the manifold from e.g. splashes of concrete during the assembly period are enclosed.

The manifold requires additionally:
Two LK Ball Valves (Art. no. 241 75 50) or LK Ball Valve Angle (Art. no. 241 79 58). Where appropriate, the ball valve is replaced by LK OptiFlow EVO II. See product range for LK Adjustment Valves.
