5. Fix the grid bearings to the prescribed positions on the horizontal mount-
ing rails, using the screws and sliding nuts provided.
6. Mount bearing sleeve “A” and the three or five bearing bushes “B” on
the nozzle grid.
7. Insert the nozzle grid/s in the frames at the appropriate position/s (note
numbering on the installation drawing).
Note: The nozzles are provided with a protective cap Ex-works, so that
no dirt can ingress. Remove these caps immediately before commis-
sioning the system.
8. Erect the housing lead-throughs (2 or 3, depending on the system) for
the spray circuits: Bore the
ø19 mm
holes and install the housing pas-
sages in accordance with the adjacent illustration.
Important!
The housing lead-throughs must be positioned in a way
that the hoses (building side) between the connections on the nozzle
grid and the housing lead-throughs, and between the housing lead-
throughs and the the small cabinet (option Z409) can be installed with
a constant downslope.
Now connect the spray circuits with the housing lead-throughs in ac-
cordance with the installation drawing provided. In so doing, note the
following points:
– The nozzles for the individual spray circuits are identified with colored
bushings (red, blue and yellow).
–
Use only the supplied hoses ø10/8 mm
(outside the duct) and
ø8/6 mm
(inside the duct). Other hoses may lead to troublesome
operation.
– When cutting hoses always
add at least 5 mm
to the specified length.
This way the hoses can be fastened correctly (down to the stop) to
the quick-action couplings of the nipples.
Important!
When cutting hoses use an
appropriate tool
providing
straight, kink-free
cuts.
– Hoses must be free of kinks and other damage (longitudinal scratches,
in particular).
– Verify correct fastening of the hoses. Correctly mounted hoses can
not be removed without pressing the locking ring.
