Technical Note 109
4.
Connect the inlet and outlet tubing to the reservoir fittings and adjust the reservoir liquid level
by turning the hollow overflow weir screw up or down with the provided Allen wrench, see
Figure 5. If you are not going to be continuously adding solution, adjust the overflow weir to
the highest level and place the inlet and overflow covers to prevent particulates from collecting
in these areas as shown in Figures 4.

with the alignment pins to register the Reservoir into the correct position
5.
Connect the heating/chilling tubing to the base inlet and outlet fittings.
6.
Plug the Control Unit into a 100-240 Volts, 50/60 Hz outlet. Connect the VP 763B Drive Unit to
the Control Unit with the control cable.
7.
Set the Speed Control Knob to 0. Turn on the power switch. Slowly increase Knob to 15.
8.
Carefully add the sample liquid to the reservoir after the unit is running. This prevents
particulates from settling out. If the reservoir is attached to a peristaltic pump system, have the
unit running before the pump is turned on. We recommend running the pump system
continuously and recycling the overflow back to the source container. Alternatively, the inlet
flow rate can be matched to the pipetting rate and the overflow can be used as an emergency
measure.
