The blower unit installation procedure is as follows:
1. Unpack the blower unit from the box it was delivered in. The blower
units are delivered fully assembled.
2.
Remove the side plastic covers cover from the blower. Unscrew the
long screws on the side using a screwdriver. Make sure to keep the
screws, as they will be needed again for assembly at the end.
3.
Mount the blower unit on the metal support. See paragraph
"Mounting single blower units on the wall / ceiling".
4. Connect the water line to the inlet on the blower units (M16x1.5).
See paragraph "Mounting single blower units on the wall / ceiling".
5.
Electrically connect the blower units to the cabinet, which supplies
power and controls operation of the fans. See paragraph "Blower unit
electrical connection".
6.
Complete blower assembly by repositioning the side plastic covers
removed previously, and fi xing them with the same screws as
removed at the beginning.
5.2 Mounting single blower units on the
wall / ceiling
The single blower units (P/N DLA%F) are designed to be installed on a
vertical wall using a special metal support to be fi xed to the wall using
screws. Check that the wall is made from suitable material and is able to
support the weight of the blower unit (concrete, not plasterboard).
Fig. 5.b
First remove the blower unit from the packaging and take off the side
plastic covers. Remove the blower unit from the steel bracket on the rear.
Rest the bracket against the wall in the position where the blower will be
installed, and then drill four holes in the wall, using the steel bracket as
the drilling template.

Fig. 5.d
After having drilled the holes in the wall, fi x the metal support using
anchor screws (not supplied).
Then attach the blower to the protrusions on the wall-mounting support
bracket.
Fix the blower unit to the bracket using the screws supplied in a bag
inside the packaging.
Fig. 5.e
When tightening the fi rst screw (M6 self-tapping in Ø=5.5 mm holes),
slightly loosen the screws on the ring clamps that support the nozzle
manifold, so as to be able to turn it and free up space to continue
mounting the unit. Tighten one screw on the right and one screw on
the left.
Then tighten the third screw (M4 self-tapping in Ø=3.5 mm hole) on
the right-hand side of the blower (opposite the terminal block). When
tightening this screw, the angle of the blower can be adjusted between
-10°/-5°/0°/+5°/+10° from horizontal, using one of the fi ve small holes
provided.
Then make the water connections, connecting the feedwater line
either on the right or left of the blower, and the water return line on the
opposite side.

Finally, fi t the two cable glands and complete the electrical wiring, as
described in paragraph "Blower unit electrical connection".
Carel also provides an additional kit (including a special plate bent at 90°)
for mounting single blower units on the ceiling.

5.3 Mounting double blower units on the
ceiling
The double blower units (P/N DLA%B) are designed to be installed on
the ceiling by anchoring them to a metal support that can support their
weight and the vibrations due to the pressurised water. To mount the
blower unit, use the special attachments provided on the unit’s metal
structure.
Carel provides additional kits with everything needed to complete
installation easily. Make sure to carefully choose the point where the
vertical support bar will be anchored. The support bar must not be longer
than 1 metre, so as to avoid excessive bending and vibrations.
