Detailed Information

Description

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 lower manifold marked RETURN has hand actuators for shutting off individual circuits.
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. 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.
LK Connection Coupling for pipe range dim: PE-X/PAL pipe in dim 16 (Art. no. 241 72 98) / PE-X pipe in dim 12x2 (Art. no. 241 94 66 ) / PE-X pipe in dim 20x2 (Art. no. 241 94 68).

Connection dimensions:
Connection feed pipe, 1" female
Connection under floor heating pipe, ¾" male Eurocone

Dimensions:
The dimensions of the manifold are listed in the table below. Center dimension pipe connections is 50 mm with 25 mm displacement between flow and return. Additional length for accessories are stated below.

LK Ball Valve Straight: 65 mm
LK Ball Valve Angle: 70 mm
LK By-Pass RF: 15 mm
LK By-Pass Delta P RF: 155 mm
LK OptiFlow EVO II incl joint nipple straight: 123 mm
LK OptiFlow EVO II incl joint nipple elbow: 93 mm
