Close the supply water shut off valve. 3. Turn off power to the humidifier with the external disconnect. 4. Using a flat screwdriver, turn the lock on the humidifier’s front cover 90° counterclockwise to release. Rotate the base of the cover outwards 6 inches, then lift upwards to remove. Fig. 28.

Using a flat screwdriver or 5/16 in. nut driver, loosen the hose clamp closest to the cylinder. 8. Pull the cylinder away from the steam hose to disengage. When free of steam hose, lift the cylinder out. 9. Some water may remain in the cylinder, even after fully draining. Have a cloth available to absorb any water.
