NOTE:
If you are using both the
FOAM
and
HIGH FOAM
inputs on the AF 2000 only one
GROUND LEAD
is connected to the module.
If you have already primed the
ANTI–FOAM PUMP
continue with Step 8.4.6.
8.4.3
Set the
ANTI–FOAM PUMP MODE SWITCH
to
PRIME
. The
ANTI–FOAM
PUMP HEAD
begins to pump.
8.4.4
Let the pump continue until the entire length of the Silicone Tubing is
full of anti–foam agent.
8.4.5
Set the
ANTI–FOAM PUMP MODE SWITCH
to
OFF
to stop the
Anti–Foam pump.
8.4.6
Set the
ANTI–FOAM PUMP MODE SWITCH
to
AUTO
to enable the
FOAM
PUMP
.
In the
AUTO
mode the
ANTI–FOAM PUMP
adds Anti–foam agent in response to
the conditions sensed by the
CONDUCTANCE PROBE
connected to the
HIGH
FOAM PROBE INPUT
on the front panel of the AF 2000. When foam contacts the
high foam sensing probe, the AF 2000 adds anti–foam agent continuously until
the foam subsides.
The BioFlo 2000 automatically limits the agitation rate to 50 RPM when foam
contacts the
CONDUCTANCE PROBE
connected to the AF 2000
HIGH FOAM
PROBE INPUT
. The agitation resumes to it’s normal value when the foam
subsides.

NOTE:
When the
ANTI–FOAM MODULE INTERCONNECTING CABLE
is disconnected from
the BioFlo 2000 Fermentor, or the
ON / OFF ROCKER POWER SWITCH
is
OFF
,
the BioFlo 2000 Fermentor LED DISPLAY reads dashes (----).
