Ordering Information - TII Accessories. If you purchased a standard or Accudispense volumetric
remote dispenser, refer to their respective operator's manuals for installation instructions.
Dispense Overflow Cutoff Float
The dispense overflow cutoff float (AY1367X1) ships with a 6 ft. [1.83 meter] cable and is designed
as a user option to ensure automatic dispensers (time or volumetric) do not overflow carboy style
containers. This accessory can be especially helpful if the actual volume of a container is unknown. It
can also protect against overflows if the entered/stored volume of a previous container has not been
changed and is set for a volume greater than the carboy being filled. Finally, the accessory can be
useful for automatic time dispenses as it is usually difficult to ensure the set time will equal a specific
volume of water. If the auto dispense is stopped by the overflow float, the Thermo Scientific TII will
change modes to normal recirculation.
1. Prior to initiating an automatic dispense (timed or volumetric), plug AY1367X1 into connector
on the back left side of the Thermo Scientific TII as shown in Figure 3-27.
2. Position carboy to be filled and place float assembly on open neck of carboy. Position float
assembly such that it will not interfere with product water stream being dispensed into carboy.
3. Initiate Auto Dispense as described in the "Automatic Dispensing" section of this manual. If,
during the auto dispense, the float is lifted by the rising water, the auto dispense will immediately
be stopped and an error message will be displayed momentarily.
