46 . STA 8000 Installation and Hardware Guide
CAUTION
ATTENTION
The cooling jacket of the STA 8000 will NOT accept pressure. Use the
lowest flow rate that provides sufficient cooling for your experiment to
minimize the pressure in the system.
La gaine de refroidissement du STA 8000 n'acceptera PAS la pression.
Utilisez le débit le plus bas qui procure un refroidissement suffisant pour
votre expérience afin de minimiser la pression dans le système.
NOTE: It is essential to maintain a very constant flow rate of coolant. The liquid should be
free of air bubbles. Changes in the liquid flow rate or the presence of air bubbles will
reduce the quality of the measurement signal.
Setting the Coolant Temperature
When using a circulator, the temperature must be controlled to within 0.2 °C (set point
± 0.1 °C).
1. Press and release the Select/Set control on the front panel.
The set point temperature value is highlighted.
2. Turn the control to set the temperature to the nearest whole degree Celsius.
A value of 20 °C is recommended.
3. Press the control again.
The degree fraction figures are highlighted.
4. Turn the control to select the desired fraction of a degree.
5. Press the control to accept the value.
Connecting to tap water
When using tap water:
1. Make sure the tap water is conveniently located near the STA 8000.
2. Connect a hose to the COOLING LIQUID IN connector.
Secure with a clamp.
3. Connect the other end of this hose to the tap.
4. Connect the other hose to the COOLING LIQUID OUT connector.
Secure with a clamp.
5. Connect the other end of the hose to a suitable drain.
The cooling inlet and outlet are located at the rear of the analyzer and are correspondingly
marked Cooling Liquid In and Cooling Liquid Out. In order to connect the cooling supply to
the STA 8000, connect the black tubing supplied to the inlet and outlet (outer diameter is
8 mm). When using tap water, connect the inlet to the tap and the outlet to a suitable drain.
When using a circulator, connect the inlet of the STA 8000 to the outlet of the circulator, and
the outlet of the STA 8000 to the inlet of the circulator.
