7. Place the drain end of the air-purging tool into a 2-liter (or larger) container to
catch the water and air bubbles that escape during the filling procedure.
Note: The 6-inch extension hose for the air-purging tool is not required for this
procedure. You can attach the extension hose to the tool, or you can
set the extension hose aside.
8. After the water is flowing through the heat exchanger for several minutes,
attach the air-purging tool to the air-purging valve at the top of the heat
exchanger. Make sure that you attach the end of the hose with a valve stem in
the center of the connector to the heat exchanger air-purging valve. If you
connect the wrong end of the hose, no water will flow.
9. When there is a steady stream of water into the container from the air-purging
tool, disconnect the tool from the heat exchanger.
Attention: If water drips from the air-purging valve after you remove the
air-purging tool, reattach the tool and disconnect it again to exercise and
reseat the seal.
10. Screw the valve cap onto the air-purging valve and hand-tighten it to provide a
secondary seal.
11. Install the inner hose access panel on the inside bottom of the heat exchanger.
