system must be used.
6. Field-install the liquid level switch (supplied and shipped with the unit).
This must be wired to the control panel.
7. Ensure test connections are accurate. The high and low level test
connections are 1/2” NPT, and are located on the end of the tank opposite
the inlet. The low level is on the center line of the expansion tank, the high
level is next to it, slightly off center. The high level rises up from the bottom
of the tank and ends 4” (102 mm) below the top; the low level rises 2” (51
mm) from the bottom of the tank.
8. Both the high and low level connections should be piped to a safe
catchment. Valves should be installed in these lines at the catch tank.
Installation of the valves should be accomplished in such a manner that
any fl ow will be visible when the valves are open.
9. Flow from the high level test connection indicates a tank that is too full; no
fl ow from the low level test connection indicates too little fl uid.
10. There is a 300 #, raised face, fl anged drain on the bottom of the thermal
buff er section, for the purpose of draining the tank when necessary. This
should be piped with a valve in the line, to a safe catchment. The valve
specifi cations outlined above apply to this valve as well.
