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-logic Installation and Operation Manual

2. Confirm that proper grounding and an approved earth ground are
provided.
3. Verify that all electrical connections are secure before applying power.
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-logic Installation and Operation Manual

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, DriSteem recommends initially running the humidifi er with the
factory default setting for skim time.
