INSTALLING STEAM CYLINDER
1. Make sure strainer is pressed into steam cylinder drain outlet and strainer
flange is flush with bottom of cylinder outlet. See Figure 12-1.
2. Use water to lubricate drain outlet on bottom of cylinder and O-ring in
drain valve body. See Figure 12-1.
Note: Because of tight clearances, perform Steps 3 through 4 only if servicing
Models XTP 002 through 017 with top-mounted steam blower. For all
other models, skip to Step 5.

until it is engaged on steam inlet of steam blower and tight against
bottom of steam blower.
4. Slide steam outlet of new cylinder all the way up into open end of
steam hose from Step 3.
5. With Warning label on cylinder facing you, lower cylinder drain outlet into
drain valve body, and rotate cylinder so side tabs line up with cylinder
guides inside cabinet. Push down on cylinder until drain outlet is fully
seated in drain valve body.
6. Slide steam hose down so it is fully engaged on cylinder steam outlet.
Re-install hose clamp(s).
7. Connect high water sensor (yellow) wire to single pin surrounded by
plastic shoulder on cylinder.
8. Connect electrode wires to pins on top of cylinder. Make sure all plugs fit
snugly and are fully engaged on pins.
Important: Three phase cylinders have color-coded dots on the cylinder
and color bands on the electrode plugs. When connecting the plugs, match
the band colors on the plugs with the dot colors on the cylinder. Refer to the
