3.4 Steam hoses
use CAREL hoses (max. 4 m long, see “Models of steam hoses”, page 3• 0).
Rigid pipes may break and cause steam leaks;
avoid the formation of pockets or traps (causes of condensate); •
avoid choking the hose due to tight bends or twisting.•
fasten the end of the hose to the connectors on the humidi er and the •
steam distributor using metal clamps, so that these do not detach due
to the high temperature.
avoid solicitations involving stress on the shank out of steam cylinder.
•
3.5 Condensate drain hose
During the operation of the humidi er some of the steam may condense,
causing a decline in e ciency and noise (gurgling).
To drain the condensate, connect a drain hose with a drain trap and a
minimum slope of 5° to the bottom of the humidi er (see Fig. 3.d). CAREL
condensate drain hoses: code cod. 1312590AXX.
Important
Important: he drain trap in the condensate drain hose must be
 lled with water before starting the humidi er.
Example of correct and incorrect installation of the steam hose and
condensate drain hose.
Final checks
the steam outlet hoses run upwards and the distributor has a □
minimum incline of 2° upwards (see Fig. 3.c);
the ends of the hose are tightened to the  ttings with metal clamps; □
the curves in the tubing are su ciently wide (radius > 300 mm / 11.8”) □
so as to not cause bending or choking;
the steam hose has no pockets or traps for condensate to form; □
the paths of the steam and condensate hoses are as described in this □
chapter (see Fig. 3.d);
the length of the steam hose is no greater than 4 metres (13.1 feet); □
the incline of the steam hose is su cient to allow correct draining of □
the condensate (> 20° for the upward sections, > 5° for the downward
sections);
the incline of the condensate hose is at least 5° at every point; □
the condensate hose always follows a downwards path and features a □
drain trap ( lled with water before starting operation) to avoid steam
being released.
