Installing a Quench CoolerInstalling a Quench Cooler
The stand-alone quench cooler (QCA) requires the use of a thermal enclosure. Follow these instructions to install both the thermal enclosure and the quench cooler on your instrument. There should be no FACS installed on your instrument. See also: About the Quench Cooling Accessory
NOTE: If you need to remove the FACS first, reverse the instructions found in "Installing the Finned Air Cooling System."
Remove the
lid(s). You
can either
manually remove the lids or select the Control/Lid/Open
function to raise the Autolid from the cell and cause it to move out of
the way.
Remove the cell cover. See Removing the Cell Cover for instructions, if needed.
Place the thermal enclosure over the cell and align the notch in the plate with the alignment pin (shown in the figure to the right).
Obtain a long 3/32-inch hexagonal (Allen) wrench from the accessory kit.
Insert the tip of the wrench into any one of the three captive screws in the thermal enclosure plate while holding onto it. You will need to exert downward pressure on the wrench while you tighten the screw a few turns. DO NOT fully tighten yet.
Repeat step
5 for the two remaining captive screws. After you have started each screw,
go back and tighten down all three screws until you feel them touch the
bottom. Do not over tighten.
Slide the cover back over the cell and replace the screws removed originally. Push the plug back into place on the side of the cover.
Connect the base purge line. The system is now ready to receive the quench cooler.
Select the correct cooler type on the Tools/Instrument Preferences/Cooler Page of the DSC instrument control software. The AutoLid and Autosampler, if applicable, are both disabled when using the Quench Cooler.
Install the two inner lids over the cell. Then slide the quench cooler into the top of the thermal enclosure using gloves to handle it, if you have already poured liquid nitrogen into it.
NOTE: The Quench Cooler may only be used to obtain Heat Flow T1.
