The hole dimensions vary depending on the distributor model:
•
model SDPOEM0000: hole to be drilled manually,
up to 30 mm (1.2 in) diameter;
•
model SDPOEM0012: hole diameter 12 mm (0.5 in);
•
model SDPOEM0022: hole diameter 22 mm (0.9 in);
D. drilling jig
Note : if you use distributors steam with an inner diameter of 30
mm (1.2 in) remove the 22 mm (0.9 in) steam inlet section from the steam
distributor.
3.2 Linear distributors for air ducts
(DP***DR0) from CAREL
Install far from any obstacle (curves, ramifi cation, section changes, grilles,
fi lters, fans).
Minimum distance between distributor and obstacle: 1…1,5 m (3.3…4.9 ft).
Increase distance in case of:
1. increase in speed of the air in the duct;
2.
turbulence decrease.
See paragraph 12.5 for installation examples.
Mounting instructions (see fi gure):
•
drill a series of holes in the wall of the pipe, using the drilling jig of the
distributor (found in the packaging of the distributor);
•
insert the distributor with the steam outlet holes facing upwards;
•
fasten the fl ange of the distributor using 4 screws.

Caution:
1. mount the distributor slightly tilted (at least 2°, to facilitate the
condensate discharge);
2.
the L-shaped supports (see element 1 Fig. 3. b) is supplied with steam
distributors models from DP085* to DP025*. For shorter lengths the
bracket can be supplied as optional (code 18C478A088).
