3.3 CAREL ventilated steam distributors for
rooms (VSDU0A*, only models UR002...
UR013)
Steam distributors for humidifi ers up to 18 kg/h (39.7 lb/h). They can
be connected onto the humidifi er or in a remote position (see fi g. 3 c.)
These distributors have a power supply inside the electrical panel (24 Vac,
Terminals X1, X2).

Caution:
in order to achieve proper steam distribution observe
the distances indicated in the fi g. above.
For the humidifi ers larger than 18 kg/h, use ventilated steam distributors
code VRDXL00000 with 230 Vac power supply (maximum capacity 45
kg/h). The distributors are designed for installation in a remote position,
and require two steam hoses with a 30 mm diameter.

3.4 Steam transport pipe
•
use CAREL fl exible hoses (max 4 m long, see section “Models of steam
conducting pipes paragraph 12.2);
•
avoid the formation of pockets or traps (cause of condensate
accumulation)
•
avoid choking the pipe with sharp bends or twists.
•
Use metal clamps to fasten the ends of the pipe to the connections
on the humidifi er and the steam distributor, so that they do not come
loose as a result of the temperature.
•
avoid strains which include mechanical stress on the cylinder steam
outlet tailpiece
3.5 Condensate drain pipe
During the operation of the humidifi er some of the steam can condense,
causing effi
ciency loss and noise (gurgling).
To drain the condensate connect to the base of the distributor a discharge
pipe with a water trap and a minimum slope of 5° (see fi g.).
CAREL condensate drain pipes: code 1312353APG.
Caution:
the condensate drain pipe trap must be fi lled with water
prior to turning on the humidifi er.
