3.6 Steam distribution
Steam injection in the duct
The maximum static pressure allowed in the duct is 950 Pa (95 mm water
column /3.7” W.C.)
The compactSteam duct models can be used with the plastic nozzle
shown in Figure 3.j (CAREL code SDPOEM00**) for the injection of steam
in the duct. The dimensions are shown in Table 3.f. These distributors can
be fi tted horizontally or vertically (hole facing upwards).
Installing the CAREL SDPOEM00** jet distributors (see
Fig.3.j)
• make a series of holes on the wall according to the distributor drilling
template (included in the packaging);
• insert the distributor with the steam opening inside the duct; fasten
the fl ange using 4 screws.

Assembling the CAREL linear distributor DP045D22R0
(Fig. 3.j.a):
• make a series of holes on the wall according to the distributor drilling
template (included in the packaging);
• insert the distributor with the steam holes facing upwards;
• fasten the fl ange using 4 screws.
Important: to allow the condensate to return through the drain
connection, fi t the distributor at a slight incline (at least 2°, see Fig. 3.l)
Condensate drain hose
During operation some of the steam may condense, causing a decline in
effi
ciency and noise (gurgling). To drain the condensate, connect a drain
hose (CAREL code 1312353APG) with a drain trap and a minimum slope
of 5° to the bottom of the humidifi er (see Fig. 3.l). The condensate hose
should run through the hole located at the top of the fi ll tank inside the
humidifi er, as illustrated in Fig 3.k.
IMPORTANT WARNING: for correct operation, the drain trap
should be fi lled with water before starting the humidifi er.
Fig. 3.o
Steam hose
• make the connection between the humidifi er and distributor using a
hose (it is recommended to use the steam hoses supplied by CAREL,
code 1312360AXX). Unsuitable hoses may weaken and crack causing
steam leaks;
• avoid the formation of pockets or traps where condensate may form;
• avoid choking the hose due to tight bends or twisting.
fasten the end of the hose to the connectors on the humidifi er and the
steam distributor using metal clamps (not supplied), so that these do not
detach due to the high temperature.
To connect to the cylinder hose steam use the adapter code CHKADAP000.
WARNING: the length of the hose must not exceed 4 m / 13ft.
Figure 3.l shows examples of correct and incorrect installation of the
steam delivery hoses and condensate drain hoses.
