TYPICAL INSTALLATION OF 1080-ST HEAT
EXCHANGER SHOWING RECOMMENDED METHOD
OF INSTALLING CONVERTERS WITH AURORA AIR
CONTROL SYSTEM:
To establish air control in converter or heat exchanger
installations, a pipe mounted air eliminator is installed as
shown in the accompanying diagram. The vortex air separator
consists of a large cross-sectional area reducing the flow
velocity and allowing air bubbles to rise into the air line to the
compression tank.
1. The air line from the vortex air separator must pitch up to
the air control tank fitting and compression tank.
2. The pump must be installed in the supply main, pumping to
the system, regardless of the size of converter or pump. In
this way, pump head is added to the piping circuit.

CAUTION
Steam hammer can cause serious damage to the tubes
of any heat exchanger. A careful consideration of the
following points before an installation is made can
prevent costly repairs which may be caused by a steam
hammer.
1. A vacuum breaker and/or vent should be used in accordance
with the type of alarm system installed.
2. The proper trap should be used for the steam system
installed.
3. The trap and one condensate return line to the trap should be
properly sized for the total capacity of the converter.
4. The trap should be sized for the pressure at the trap, not the
inlet pressure to the steam controller.
