XT SERIES INSTALLATION, OPERATION, AND MAINTENANCE MANUAL
CAUTION
Follow steam piping recommendations
Controlling condensate fl ow and collection in an XT Series humidifi er system is critical to maximize performance. Failure to follow
the steam piping recommendations in this manual can cause system pressure fl uctuations and increase cylinder pressure, steam
velocity, and condensate noise.
Hot discharge water
Discharge water can be as hot as 212 °F (100 °C) and can damage some drain plumbing materials not rated for hot drain
water. To prevent such damage, make sure drain water tempering is selected, and supply water is not heated. Do not shut off
supply water to the cylinder before it is drained.
Excessive supply water pressure
Supply water pressure greater than 80 psi (550 kPa) can cause the humidifi er to overfl ow.
WARNING
Electrical shock hazard
If the humidifi er starts up responding to a call for humidity during maintenance, severe personal injury or death from
electrical shock could occur. To prevent such start-up, follow the shutdown procedure on Page 49.
