The Auspex Radiant manifold is supplied with two ¾” hose unions for filling and testing.
Disconnect caps on drain/fill valves and connect two hose unions to both end caps, or alternatively connect two hoses onto drain/fill valves with hose clamps.
Open both the blue and red isolation valves on the drain points.
Close all valves on the flow and return manifolds.
Connect the hose from the mains water tap to the flow manifold. And run a hose from the return manifold to a suitable drain.
Working from left to right on the manifold, one loop at a time, remove the air from each loop by opening the flow and return valve for that circuit.
To open the return valve (white cap) turn it anti-clockwise until it stops.To open the flow valve (flow meter) lift up the black nut and turn valve at the base anti-clockwise approximately 3 turns. To open the return valve (white cap) turn it anti-clockwise until it stops.
To open the flow valve (flow meter) lift up the black nut and turn valve at the base anti-clockwise approximately 3 turns.
Turn on the mains water supply and observe water flowing into the drain until water runs clear with no bubbles. Repeat steps 6 and 7 for each loop.
Re-open all circuits and close off water supply on both drain valves.
