WARNING
All information in this manual is for
reference and guidance purposes,
and does not substitute for required
professional training, conduct,
and strict adherence to applicable
jurisdictional/professional codes and
regulations.
Once the system has been fi lled,
any modifi cation to the tank or
connected piping requires purging
of the work area to prevent ignition
of potentially fl ammable vapors.
Consult factory prior to beginning
work. Consult Material Safety Data
Sheet (MSDS) for your thermal fl uid
for fl ammability limits.

CAUTION
If the deaerator/thermal buff er/
expansion tank is located outdoors, a
nitrogen blanket is required.
 Vent Connections
Adhere to the following for vent connections:
1. Make vent connection in a manner that will prevent penetration of water
or foreign bodies into the tank. This connection must always terminate
in a safe, well ventilated area and has to be free of obstruction, open to
atmosphere, and arranged in such a manner that, in the event of discharge
from the system, thermal fl uid could drain into a catch tank without
danger to personnel or property.
2. Make the vent run the same size as the tank outlet. It should run pitch
down from the outlet of the tank to the catch tank.
3. If nitrogen is used on the system, the vent can be reduced to 2” (51 mm)
and should be piped with a positive closing valve at the catch tank.
4. Ensure the connection between the tank outlet and the horizontal pump
inlet is as close to a vertical drop as possible. It should have the minimum
bends and length of pipe.
5. Ensure the inlet to the deaerator is higher than or equal to the highest
point in the system, or a pressurized 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.
11. An inspection opening is located at the highest point on the tank. Access
to this port is recommended but not required.
12. Refer to the maintenance schedule for recommendations on draining the
buff er tank. For positioning of all connections on tank, see Figure 14.
