3. INSTALLATION
3.1. Fitting on stack
The components necessary for adaptation to the emergences of the ducts vary
from one site to another.
In th cas of an individual duct, a horizontal platform, located at the level of
the emergence of the duct, is necessary for attachment and for airtightness with
the fan. A plane plate of the right dimensions, attached to the top of the stack, is
sufficient.
For th grouping of ducts, an adaptation pl num compliant with the
recommendations stated below is necessary to ensure proper aeraulic operation
of the whole (loss of head minimized) and for attachment and tightness with the
fan(s).
General recommendations for the placement of adaptation components:
Th adaptation compon nts must b mad of a mat rial strong nough to b ar th w ight of th fan(s).
Th latt r must b fast n d to th stack s cur ly and so as to assur a good s al with it; th pl num as
a whol must also b p rf ctly s al d.
Attachm nt of th control unit:
For ach cas ncount r d, on of th dg s of th pl num or
of th stack must b within 550 mm of th c ntr of th fan to
allow th attachm nt of th control unit.
3.2. Cas of an individual duct
For a rectangular duct, the constraints are the following:
The top platform must be rectangular and measure at least 6 x
6 mm.
The opening cross-section of the duct must not exceed 245 x 245
mm if it is desired to avoid reducing its cross-section.
The fan must be centred on the duct.

8/2
TF5574_C
Aereco S.A.
For a circular duct, the constraints are the following:
The top platform must be rectangular and measure at least 6 x
6 mm.
The opening cross-section of the duct must not exceed Ø35 mm
if it is desired to avoid reducing its cross-section.
The fan must be centred on the duct.
3.3. Cas of ducts group d und r a singl fan
For all grouped duct configurations, an adaptation plenum is necessary. The plenum must:
provide a top platform measuring at least 6 x 6 mm.
provide a circular outlet Ø35 mm centred on the stack
ensure a height of air of at least 18 mm between the end of the stack and the outlet section Ø35 mm.
The fan must be centred on the outlet section Ø35 mm.
Example of a typical stac of the collective and individual type:
3.4. Cas of ducts group d und r 2 fans
For all grouped duct configurations, an adaptation plenum is necessary.
The plenum, even if made in a single piece, must provide 2 distinct volumes, perfectly sealed from one
another.
For each of the 2 units, the plenum must provide a circular outlet Ø35 mm centred as closely as possible on
the grouped duct.
Th pl num must nsur a h ight of air of at l ast 180 mm b tw n th nd of th stack and th outl t
s ctions Ø350 mm.
The fans must be centred on the outlets Ø35 mm.
Each 35 mm outlet must be at least 1, mm from the other and at least 5 mm from the bulkhead
separating the volumes.

3.6. Anticipation of maint nanc and chimn y sw ping constraints
In order to allow access to the ducts located under the fan (inspection, chimney sweeping) it may sometimes be necessary to
incorporate one or more of the following features:
Soot door. This is generally located on the side of the stack or of the plenum.
Top plate tipping system (with hinges and catches).
Attachment that can be removed from and refitted on the top plate.
3.7. Installing th fan
1) Ensure the proper adaptation of the fan on its stack (see section above).
Th plat holding th outl t Ø350 mm can b d sign d with 3 crimp d M8 nuts position d as shown
b low to allow th attachm nt of th fan.
2) Remove the fan from the pallet.
Us only th 2 handl s locat d und r th uprights to handl th fan.

3) Place a gasket as a seal between the top plate and the base of the fan.
4) Attach the fan to its specific adaptation using 3 x Ø 8 mm stainless steel screws + washers.
Note: The 2 handles can be removed by pinching them; this eliminates a potential source of noise due to
mechanical vibration.
5) Position the control box as low as possible on a vertical surface. The surface must be accessible; favour th sid
facing North to r duc th influ nc of dir ct sunlight. It must be positioned so that the cable connecting the fan to it is
not loose. If necessary, fit cable clamps.

6.1. Prior warnings
B for doing any work on th applianc :
Th applianc may still b charg d v n though th 230 VAC pow r supply circuit has b n cut off,
l ading to a risk of l ctrical shocks.
 Wait at least 5 min after cutting off the power supply before intervention on the appliance.
Th applianc may b stopp d but r starts automatically (for xampl if th r is a mom ntary
int rruption in th control circuit of th MS v rsion), with a risk of injury.
 Never insert anything through the fan, and in particular the suction stream in which the turbine is located.
 Never handle an appliance or remove it from its stack when it is live.
 Cut off the power supply and make sure that it cannot be reconnected.
 Wait for the turbine to come to a full stop.
6.2. Maint nanc
We recommend carrying out a visual observation of the proper operation of each fan and cleaning its blades once a year:
1) Cut off the power supply.
2) Remove the product from the base on which it is placed in order to reach the turbine.
W aring suitabl glov s whil handling th product is strongly r comm nd d (som of th m tal
parts hav sharp dg s).
3) Using a cloth moistened with a cleaning product or a brush, which should be non-metallic so as not to damage the
galvanization, clean the blades of the turbine and the fixed vanes.
Tak car not to twist th blad s or th van s of th fan during this op ration. Do not apply solv nt
on th ball b arings (this might impair th ir lubrication).
4) Wipe with a dry cloth
5) Put the fan back in place
6) Reconnect the power supply. In the MS mode, restarting will take a few minutes, the time needed to reset the modules.
