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.
Failure to ensure vent connections
terminate into a well-ventilated
area with catch tank may create an
environmental hazard.
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 13.
Catch Tank
Adhere to the following for the catch tank:
1. Ensure the heater safety relief valve outlet and connections on the DA tank
are piped to a safe catch tank. The catch tank must be appropriately sized
based on the system volume and confi guration.
2. Under normal operating conditions, the catch tank should be empty. Fluid
that is expelled into the tank should not be reintroduced into the system.
Drain/Fill Connection
The system is usually fi lled from the lowest point, with the aid of a pump. On skid-
mounted units, a drain and fi ll connection is provided in the inlet piping to the
pump. See Figure 15.
Pressure Gauges
The range in which readings are expected to fall should comprise mid-scale on
the pressure gauge chosen (See Figure 16). Pressure gauges must be able to
withstand overpressure equal to the rating of the safety relief valves, normally
100 psig.
Thermometers
Thermometers should read up to 650 F (343 C). For systems with higher
operating temperatures, thermometers should be selected accordingly.
