Filling and Purging the Manifold

To ensure proper system performance, it is important to fill and purge the

system at the boiler or at the manifold. Refer to the following instructions to

fill and purge at the manifold.

1. Connect a hose from a faucet to the fill valve on the supply manifold.

2. Connect a separate drain hose to the return manifold and place the other

end into a large bucket or drain.

3. Remove the flow meter locking cover.

4. Close all valves on the manifold (both supply and return) as well as the ball

valves (A2771251 or A2771252) installed on the supply and return lines.

5. Use the square tool on the cap of the hose bib fill port to open the fill

valves on the supply and return manifold.

6. Open the valves for the first loop on the manifold.

7. Fill the loop with water. Continue the filling process until the water is clear

with no bubbles.

8. Repeat Steps 4 through 6 to fill and purge each manifold loop.

9. Replace the flow meter locking cover.
