5.8 Checking the Humidifier Lid Seal
Under normal use, the humidifier lid seal should not require any maintenance or replacement. The seal may
be cleaned as needed by wiping it with a damp cloth. If necessary, the humidifier lid seal may be removed for
further cleaning. Gently peel the seal from the humidifier lid and clean it in a solution of warm water and a mild
liquid dish-washing detergent. Rinse with clean water. Wipe completely on both sides. Allow the seal to air
dry. Inspect the seal for damage. If the humidifier lid seal show signs of wear or damage, it should be re-
placed.
To install or reseat your humidifier lid seal, fully open the humidifier lid. Position the seal (1) against the inside
of the lid so the seal’s center hole aligns with the humidifier outlet port. Confirm that the seal is positioned so
the wire channel (2) in the seal is below the humidifier outlet port (3).
NOTE
The seal only fits properly in one orientation.
With the seal loosely in place, start at the bottom (1) and gently press the edges of the seal into the channel in
the lid of the humidifier. Continue sliding your fingers all around the rectangular perimeter of the seal until the
outer edge is completely seated. Next, press the seal around the humidifier outlet port (2) until the center of
the seal is fully seated. Finally, go back and run your fingers around the rectangular perimeter of the humidi-
fier lid seal once more to confirm it has not become dislodged.
