Start-up procedure
Operation
Safety functions
XT humidifiers are protected against
running dry — current does not flow if the
electrodes in the steam cylinder are not
submerged in water.
If the current rating exceeds 120% of nominal
current, the drain valve opens automatically. As
the water level drops, the current rating drops
back to the nominal value.
If the current rating exceeds 120% of the
nominal current after several drainage
operations, the humidifier shuts down
automatically.
Capacity limitation
XT humidifier capacity can be limited to a
user-specified maximum:
Using the keypad/display or Web interface, from
the Main menu, and select Tank Setup, then
select Capacity Adjustment for menu options.
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

WARNING
Electric shock hazard
Only qualified electrical personnel should
perform start-up procedure.
Contact with energized circuits can cause
property damage, severe personal injury
or death as a result of electrical shock or
fire.
Make sure that all electrical covers are
in place and secure before turning on
electrical power. These include the heater
terminal cover, electrical panel cover, and
subpanel access panels.
