XT SERIES INSTALLATION, OPERATION, AND MAINTENANCE MANUAL
Note:
DriSteem recommends keeping a spare steam
cylinder in stock during the humidifi cation
season. See “Replacement parts" on Pages
57 and 59.
1. When steam cylinder is completely empty, turn humidifier off. Place all
power disconnects in OFF position, and lock in OFF position.
2. Remove cabinet doors, and make sure cylinder and humidifier components
have cooled.
3. Carefully pull the electrode plugs straight up off the cylinder to ensure no
damage to the plug boot occurs.
4. Inspect cylinder plugs. Obtain replacement plugs from DriSteem if
deterioration, corrosion or loose fit occur.
5. Disconnect the high water sensor wire.
Note:
Because of tight clearances, perform Steps 6 through 7 only if
servicing Model XTP 002 through 017 with top-mounted steam
blower. For all other models, skip to Step 8.
6. Remove both clamps on steam hose that connects to cylinder and
steam blower.
7. Slide steam hose from Step 6 all the way up until it is tight
against bottom of steam blower. Skip to Step 9.
8. Loosen steam hose clamp, and disconnect steam hose from cylinder.
9. Place hands palms-down below cylinder on both sides of drain outlet.
10. Press up against bottom of cylinder with backs of hands while pressing
down against cabinet floor with fingers.
11. Raise cylinder until drain outlet clears drain valve body and the side tabs
on the cylinder have cleared the cylinder guides. Remove cylinder from
cabinet.
12. Vacuum scale and debris out of drain valve port.
Note:
For more thorough cleaning, see drain valve maintenance instructions
on Page 51.
13. Replace O-ring in drain valve body (new cylinder ships with new O-ring).
Make sure O-ring is correctly placed.
14. Dampen O-ring seals
with water
before replacing cylinder.
Do not use
lubricant or other substance.
15. Install new steam cylinder. See “Installing steam cylinder” on Page 12.
16. Connect steam hose to cylinder, and re-install hose clamp.
17. Connect high water sensor (yellow) wire to single pin surrounded by
plastic shoulder on cylinder.
18. 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
wiring diagram shipped with the humidifi er if necessary.
If returning humidifi er to operation, see the start-up procedure on page 48.
