As allowed by the dimensions of the air duct, the distributor must be as long as possible and located away from curves,
branches, changes in cross-section, grills, filters and fans.
The minimum recommended distance between the steam distributor and the nearest obstacle is around 1
÷
1.5 metres, yet this
greatly depends on the operating conditions. This distance, in fact, increases with:
•
an increase in the air speed in the channel;
•
an increase in the relative humidity of the air before and, above all, after humidification;
•
a decrease in turbulence.
Follow the indications and the distances between the distributor and the walls of the ducting and/or between two
distributors, as indicated in the figures below (distances in mm).

The humidifier must be connected to the distributor using a pipe suitable for
this purpose, such as the Carel flexible pipe. The use of unsuitable tubing may
cause weakening and cracking and consequently steam leaks.
The layout of the tubing must be such as to avoid the accumulation of
condensate, with consequent noise (gurgling) and reduction in efficiency;
the path of the tubing must exploit gravity to drain the re-condensed
steam back to the boiler or to the distributor.
Pockets or traps must thus be avoided, in that the condensate may be
trapped; attention should also be paid to avoid choking the pipe due to
sharp bends or twisting (see Fig. 4.6.1). Before operation, the PE film
(wrapping) the pipe should be removed to assist correct heat exchange.
Using screw clamps, tightly fasten the end of the pipe to the humidifier
and steam distributor fittings.
According to the position of the steam distributor, the path of the pipe may use one of two following solutions:
1. rise upwards with a vertical section of at least 300 mm, followed by a curve with a minimum radius of 300 mm and
finally a downwards section with a constant gradient of no less than 5° (see Fig. 4.6.2);
2. for short paths (less than 2 metres), curves with a minimum radius of 300 mm, followed by a rising section with a
gradient of no less than 20° (see Fig. 4.6.3).
