a. Use the 0.05-inch hex key to loosen (approximately two turns) the eight screws that
hold the two saturated desiccant canisters to the desiccant cartridge. Remove the
canisters.
b. Turn the desiccant cartridge upside down and peel the old humidity indicator off the
window. Discard the used indicator.
NOTICE Always wear lab gloves or finger cots, or use laboratory tissue, when
handling a new humidity indicator. Oil or moisture from skin can discolor the
indicator.

the desiccant) and remove the new humidity indicator.

window so that the flat edges of the indicator are aligned with the edges of the
cartridge. The text should be visible through the window when you turn the cartridge
right side up.

that it does not come loose in the desiccant compartment when you reinstall the
cartridge.
