Refilling the Desiccant Tanks
When desiccant becomes clogged or contaminated, you should replace the des-
iccant in all three tanks to ensure optimum performance.
1 Remove the desiccant tank from the carousel.
See “Replacing Desiccant Tanks.”
2 Remove the the tank end plate.
Remove the six 10-32 self-tapping screws from the end plate.
3 Remove the screen cap.
Remove the two 1/4-20 nuts from the center post and pull the screen cap out.
4 Remove the old desiccant.
5 Replace the gasket on the flange, if necessary.
6 Fill the tank with fresh desiccant.
Fill the tank with the weight of desiccant indicated in the following table.
