Section 7
Filling and Purging the Manifold
To ensure the manifold provides enough water for superior performance, fill
and purge the system at the boiler or at the manifold.
If you choose to fill and purge at the manifold, see the following
instructions.
1. Connect a water hose from a faucet to the fill valve on the supply
manifold cap.
2. Connect a separate drain hose to the cap on the return manifold and
place the other end into a large bucket or into a drain.
3. Close all valves on the manifold (both supply and return manifold),
as well as the ball
valves installed on the
supply lines.
4. Open the valves for
the first loop on the
manifold.
