steam hose off vertically.
11. Using a fl at head screwdriver, press the tab on
the cable tie to release it. Lift the cylinder straight
up to disengage it from the humidifi er.
12. Place the new cylinder on the side mounting slots
within the unit, ensuring the cylinder mounting
stubs are seated properly.
13. Replace the cylinder plugs on the pins, ensuring
the white sensor plug goes on the single pin,
which is offset from the others.
14. Ensure the plugs are secured on the pins. If
the plugs are loose, they may be temporarily
squeezed together, however, the plugs must
be replaced since a loose plug could generate
enough heat to melt and destroy the plug.

clamp(s).
16. Push the “On-Off-Drain” switch to the “On”

will drastically shorten the cylinder life.
