Open the sealed packet from the desiccant replacement kit and remove the new humidity
indicator (the indicator should be blue).
Press the new indicator onto the window so that the flat edges of the indicator are aligned
with the edges of the window. (You can trim the indicator with a pair of scissors if
necessary to make it fit the window.) Make sure the indicator is pressed tightly against the
window.
Figure 30. New paper humidity indicator
The text on the indicator should be visible through the window when you turn the
module right side up.

13. Install the new desiccant canisters.
Insert each canister into the channel of the desiccant module so the holes in the module
are aligned with the holes in the canister. If you are replacing the set screws, remove four
new ones from the desiccant replacement kit and insert them into the desiccant module.
Tighten the screws (approximately 2 turns) until they are flush with the surface of the
desiccant module.

NOTICE Do not overtighten the set screws or you may damage the desiccant module
or the canisters. (If the module is bowed, the screws are too tight.)
