Instruction manual
Optional accessories for this unit include a standard remote dispenser,
Accudispense volumetric remote dispenser, dispense overflow cutoff float
and printer. For ordering information, refer to Ordering Information - TII
Accessories. If you purchased a standard or Accudispense volumetric
remote dispenser, refer to their respective operator’s manuals for installation
instructions.
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 Barnstead 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 Barnstead TII as
shown in Figure 3-26.
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.
Caution This accessory is not intended for use with small containers as its
weight could cause small, lightweight containers to tip over.
