CAUTION!
Do not over-tighten the hose clamp on the steam hose. Maximum torque for 7/8 in (22 mm)
clamps is 12 in·lbs (135 N·cm), and 16 in·lbs (180 N·cm) for 1-3/4 in (45 mm) clamps.

Steam Line Slope
–
To minimize formation of condensation and maximize efficiency, the steam lines made of rigid pipes
(copper or stainless steel) must be insulated with a minimum of 1 in (25 mm) of pipe insulation over
its entire length.
–
The weight of the steam line must be supported so there is no load on the humidifier.
WARNING!
Risk of severe burns from exposure to hot steam vapours!
Restrictions in the cross-section of the steam line will cause excessive backpressure in the
steam cylinder when the unit is operating, which may cause unexpected release of hot steam
vapors. Bare skin exposed to the hot steam vapours can result in severe burns.
Prevention
:
Observe the following:
•
Upon completion of the installation, purge the steam line to remove any contaminants and
installation materials.
•
If using a steam hose make sure there are no kinks in the hose. A heated hose is more likely
to kink.
•
To prevent condensate pockets, the steam line must not sag. If necessary, support the steam
line with pipe clamps, trough, or wall brackets, and install a condensate drain at the lowest
point in the steam line.
•
Do not install a shutoff valve (e.g. a manually operated shutoff valve, solenoid valve, etc.) in
the steam line.
