4. Verify that the reservoir on the external coolant circulator contains sufficient
coolant as specified by it manufacturer. If additional coolant is required, use a 50:50
mixture of water and ethylene glycol based commercial antifreeze to add sufficient
coolant.
5. Replace the reservoir cap.
6. Plug the external circulator into a 100-240 V
AC
, 47-63 Hz power source.
7. Turn the coolant circulator on.
CAUTION!
!
When configuring an external coolant circulator, adhere to
the following:
• Minimum coolant flow rate is 2.0 liter/minute
[0.55 gallon/minute].
• Coolant pressure should never exceed 25 psi.
• Never set the circulator temperature below the dew
point.
8. Verify there are no leaks or air bubbles in the hoses.
NOTE:
Small air bubbles (approximately the size of bubbles in soda)
are common, particularly immediately following start up.
These bubbles do not prevent proper operation.
• If no problems are observed, proceed to step 9.
• If there are leaks or air bubbles, turn the circulator off and correct the
problem(s) by securing the hoses or adding more coolant to the reservoir.
Turn the circulator back on. Recheck and if there are no problems, proceed to
step 9.
9. Turn on the NIRvana HS.
10. Launch LightField.
5.4.1 Experiment Shutdown
Following the completion of a liquid-cooled experiment, perform the following
procedure:
1. Turn off the NIRvana HS power supply.
2. Turn off the coolant circulator according to all manufacturer-supplied
documentation and procedures.
3. If desired, carefully disconnect the coolant hoses from the NIRvana HS.
WARNING!
If the NIRvana HS is to be shipped, to avoid potential
catastrophic damage to the camera, all coolant must be
drained from it.
