The CRUV humidifier is available with either the LW series
controller or the optional Vapor-logic4 control system. If your
system is equipped with the Vapor-logic4 system, refer also to the
Vapor-logic4 Installation and Operation Manual as noted in the
instructions below.
After the system is installed and connected properly:
1. Verify that the humidifier, controls, piping, electrical
connections, steam supply, and dispersion units(s) are installed
according to the following:
• Installation instructions in this manual
• Vapor-logic4 Installation and Operation Manual (if using the
Vapor-logic4 control option):
– Installation section
– Installation checklist
• Wiring diagrams shipped with humidifier
• All governing codes
2 Confirm that proper grounding and an approved earth ground
are provided.
3. Verify that all electrical connections are secure before applying
power. See torque requirements in Table 36-1.
4. Make sure all electrical covers are in place and secure. See
Warning at right.
5. Verify that the humidifier is mounted level and securely
supported before filling with water (see the operating weights in
Table 4-1).
6. Verify that the humidifier is level front to back and side to side
after it is full of water.
7. Refer to “LW series controller” on Page 28 or the “Operation”
section of the Vapor-logic4 Installation and Operation Manual.
8. Perform all applicable “Start-up checklist” items on Page 28 or 29.
Note: During start-up, do not leave the humidifier unattended.
9. Monitor humidifier operation through multiple fill cycles.
10. On tap/softened water units, water skims from the humidifier
after every fill cycle. Adjust the amount of skim by increasing or
decreasing the skim time. See "Skim duration" on Page 33.
At start-up, DRI-STEEM recommends initially running the
humidifier with the factory default setting for skim time.
