ULTRA-SORB MODEL XV INSTALLATION, OPERATION, AND MAINTENANCE MANUAL
Start-up checklist
1. Ensure all component wiring and piping connections are complete as
shown in the wiring diagrams provided with the unit.
2. Create demand for humidification by providing a demand signal to control
cabinet option 1 or control valves options 2 and 3.
3. Prime the header overflow P-trap, if installed. Ensure that it is installed as
recommended in “Optional header overflow P-trap water seal” on Page
17.
4. Turn on steam to the heat exchanger. Inspect connections for piping leaks.
5. Turn on the modulating steam valve, and check for piping leaks.
6. Ensure that the traps are operating.
7. Check the dispersion tubes for leaks.
8. Ensure that the dispersion tubes are oriented with the tubelets at a right
angle to the airflow. See Figure 9-1.
9. Check for any other leaks from header connections.
10. If a temperature switch is installed (control options #2 or #3), with both
heat exchanger and humidification steam turned on, turn off steam to the
heat exchanger. Make sure the temperature switch turns off the modulating
steam valve to stop humidification steam from entering the dispersion
assembly. Depending on the installation, it may take several minutes for the
steam valve to close.
11. Heat exchanger operation:
• Ensure operating steam pressure is at least 5 psig (35 kPa).
• Ensure on-off and shut-off delay (15 minutes after non humidifi er demand
- control options #1 or #4) conditions are working as intended.
