3.3 CAREL blowers for room installation
(VSDU0A*, VRDXL*)
Steam distributors for installation in rooms. These come with a fan
to assist steam absorption. The VSDU0A* blowers can be used on
humidifi ers with fl ow-rates up to 18 kg/h (39.7 lb/h), i.e. models UR002...
UR013. They can be connected to the top of the humidifi er, or separately
in a remote position using the fastening support VSDBAS0001 (see Fig.
3.c). These distributors have a power supply inside the electrical panel
(24 Vac, Terminals X1, X2).

C > 2,1 m (>82.6")
D > 1 m (>39.4")
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, the are ventilated steam
distributors code VRDXL00000 with 230 Vac power supply, external
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, c
connected to a "Y" adapter (available as accessories, contact Carel for
details on the product code).
C > 1,8 m (>70.8")
D > 1,2 m (>47.2")
In this case, terminal J19.1 on the control board is used as a voltage-free
contact (normally open when there is no production - SSR OFF). This
contact has a maximum rating of 2 A.

3.4 Steam transport pipe

•
use CAREL fl exible hoses (max 4 m long, see section "Models of steam
conducting pipes");
•
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 part 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.3.d).
CAREL condensate drain pipes: code 1312368AXX (ø 10mm) -
(CHOSE00516 (5/16") for North American market) for DP* series linear
steam distributors; code 1312353APG (ø 7mm) - (CHOSE0038 (3/8") for
North American market) for steam blowers and nozzles.
Caution: the condensate drain pipe trap must be fi lled with water
prior to turning on the humidifi er.
