3.3 CAREL ventilated steam distributors for
rooms (VSDU0A*, only models UR002...
UR013)
Steam distributors for humidi ers up to 18 kg/h (39.7 lb/h). They can
be connected onto the humidi er or in a remote position (see  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  g. above.
For the humidi 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.
A > 0,9 m (>36”) E > 0,9 m (>36”)

C > 1.8 m (>72”) G > 1.2 m (>48”)
D > 1.2 m (>48”)
3.4 Steam transport pipe
• use CAREL  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 humidi 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 humidi er some of the steam can condense,
causing e 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  g.).
CAREL condensate drain pipes: code 1312353APG.
Caution: the condensate drain pipe trap must be  lled with water
prior to turning on the humidi er.
