Installation
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.
Caution
This accessory is not intended for use with small containers as its
weight could cause small, lightweight containers to tip over.
