WARNING
Read all warnings and instructions
This page provides important safety instructions; it is intended to supplement — not replace — the humidifi er's Installation,
Operation, and Maintenance Manual (IOM). Read the IOM that was provided with the humidifi er before performing
service or maintenance procedures on any part of the system. Failure to follow all warnings and instructions could
produce the hazardous situations described here and in the IOM, resulting in property damage, personal injury, or
death.
If the IOM is missing, go to www.dristeem.com to download a replacement.
Hot surfaces and hot water
Steam humidifi cation systems have extremely hot surfaces, and water in tanks, electrode cylinders, steam pipes, and
dispersion assemblies can be as hot as 212 °F (100 °C). To avoid severe burns, allow the entire humidifi cation system to
cool.
Follow the cool-down procedure in the humidifi er's IOM before performing service or maintenance procedures on any
part of the system.
Carbon monoxide, fi re, explosion, and electrical shock hazards
Improper installation, adjustment, alteration, service, maintenance, or use can cause carbon monoxide poisoning, fi re,
explosion, electrical shock, and other hazardous conditions. These hazardous conditions could cause personal injury,
property damage, or death. To prevent hazardous conditions, read all warnings; lock all power disconnect switches in
the OFF position before removing any access panels; and consult a qualifi ed installer, service agency, local gas supplier,
