3.4 Steam hoses
use CAREL hoses (max. 4 m ( max. 13 feet)) long, see “Models of steam •
hoses”, page 47). Rigid pipes may break and cause steam leaks;
avoid the formation of pockets or traps (causes of condensate); •
avoid restricting 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 situations that cause stress on the outlet of the steam cylinder and •
on the distributor pipe (see minimum diameter of curving).
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 CHOSE00038
Important: the 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 o
incline of 2° upwards (see Fig. 3.c);
the ends of the hose are tightened to the ttings with metal clamps; o
the curves in the tubing are suciently wide (radius > 300 mm / 11.8”) so o
as to not cause bending or choking;
the steam hose has no pockets or traps for condensate to form; o
the paths of the steam and condensate hoses are as described in this o
chapter (see Fig. 3.d);
the length of the steam hose is no greater than 4 metres (13.1 feet); o
the incline of the steam hose is sucient to allow correct draining of o
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; o
the condensate hose always follows a downwards path and features a o
drain trap (lled with water before starting operation) to avoid steam
being released.
