kit includes vapor hose, a dispersion tube and hardware. Note
that the capacities of models VM-30 and VM-34 require multiple
tube assemblies and therefore cannot use a hose kit. For multiple
tube assemblies, see information on Rapid-sorb on pages 24-30.

WARNING!
Dispersion tube, vapor hose, tubing, or hard
pipe can contain steam, and surfaces can be
hot. Discharged steam is not visible. Contact
with hot surfaces or air into which steam has
been discharged can cause severe personal
injury.
