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 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 1312353APG
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
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 ttings with metal clamps;
Ƒ the curves in the tubing are suciently 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 sucient 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 (lled with water before starting operation) to avoid steam
being released.
