3.4 Steam
hoses
•
use CAREL hoses (max. 4 m long, see “Models of steam hoses”, page 30).
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 humidifier 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 humidifier some of the steam may condense,
causing a decline in efficiency 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 humidifier (see Fig. 3.d). CAREL
condensate drain hoses: code 1312353APG
Important
: he drain trap in the condensate drain hose must be
filled with water before starting the humidifier.
Example of correct and incorrect installation of the steam hose and
condensate drain hose.
Final checks
Ƒ
the steam outlet hoses run upwards and the distributor has a
minimum incline of 2° upwards (see Fig. 3.c);
Ƒ
the ends of the hose are tightened to the fittings with metal clamps;
Ƒ
the curves in the tubing are sufficiently wide (radius > 300 mm / 11.8”)
so as to not cause bending or choking;
Ƒ
the steam hose has no pockets or traps for condensate to form;
Ƒ
the paths of the steam and condensate hoses are as described in this
chapter (see Fig. 3.d);
Ƒ
the length of the steam hose is no greater than 4 metres (13.1 feet);
Ƒ
the incline of the steam hose is sufficient to allow correct draining of
the condensate (> 20° for the upward sections, > 5° for the downward
sections);
Ƒ
the incline of the condensate hose is at least 5° at every point;
Ƒ
the condensate hose always follows a downwards path and features a
drain trap (filled with water before starting operation) to avoid steam
being released.
