The manifold comes complete with a drain and air vent assembly, which can be positioned on either end of the manifold. Isolation valves are supplied separately for the supply end of each manifold. The bottom manifold is the flow and the top manifold is the return. Each manifold port comes complete with a Polymax push fit connection. Pipes are connected to manifolds by inserting a pipe stiffener (UFHPS15) into the pipe and simply push fitting the pipe into the port. The flow meter on each flow port of the manifold provides a visual indication of the flow through each circuit. Manual balancing can be undertaken by using the blue cap on the return manifold for manual adjustment, or removing the blue cap completely.
Preparing and installing the manifold
Remove the manifold from the box and arrange the flow and return manifolds to ensure that the inlets/outlets are pointing downwards. Remove the air vent and drain valve from the packaging and connect to the desired end of the manifold.Ensure the seal is correctly in place before tightening the compression nut by hand on to the manifold. To ensure the valves are securely connected to the manifold, use a 38mm spanner or wrench to tighten by a further half turn. Remove the isolating valves (supplied separately) from the packaging and connect to the opposite end of the manifold. As with the air vent and drain valve, ensure the seal is correctly in place before tightening the compression nut by hand on to the manifold. Then, complete the connection by using a 38mm spanner or wrench to tighten by a further half turn. Fix the manifold horizontally in the desired position utilising both screw holes on each bracket with screws and washers provided. The manifold is now in position and ready to be connected to the mains from the boiler and the under floor heating pipe circuits.
