Mounting
4.3.1 Spark arrester
You can mount the spark arrester:
- during installation of new ductwork
- afterwards in an existing duct
2
ATTENTION
Allow sufficient space between the duct and the wall
to install the spark arrester.
You can install the spark arrester as a whole. Lift it
with (e.g.):
- straps
- a forklift-truck with pallet
SparkShield-250 | 400 | 500 | 10 | 16 | 20:
When no lifting gear is available, we recommend to
install the inlet and outlet separately and to
reconnect them afterwards.
SparkShield-630 | 24:
You must install the spark arrester as a whole. It is
provided with a lifting bracket to facilitate various
lifting techniques.
To install the spark arrester, do the following.
ATTENTION
Obey the mounting instructions as indicated in:
-
Fig. III (airflow direction) and
- Fig. IV (duct installation) on page 6
• In case of installation in an existing duct: cut away a piece
of the existing duct. Refer to Fig. V on page 10 (D) for
the duct length to be removed.
• Support the loose ends of the duct.
WARNING
Duct supports must be able to carry the weight of
the spark arrester. Refer to paragraph 1.4 for the
weight of the spark arrester in question.
• Extend all duct clamps.
• Slide a duct clamp Ø 250/400/500/630 mm over both duct
ends.
• Duct metric size (mm):
Place a connection ring Ø 250/400/500/630 mm (A) in
both duct ends and fasten them with self-tapping screws
(min. 6).
• Duct imperial size (inch):
Place a reducer metric-imperial Ø 10/16/20/24 in. (A) in
both duct ends and fasten them with self-tapping screws
(min. 6).
• Lift the spark arrester (C) in line with the duct and mount
it to the connection rings with the duct clamps (B). Tighten
the clamps with a box spanner.
2. The installation of any product(s) not included in the initial design of an
extraction system could add additional static pressure to the overall system
design. By doing so, the result may be a reduction of airflow at the extraction
point.

Dustbin
The SparkShield comes with two different dustbins. You can
install the preferred one.
Recommended use:
- SparkShield-250 | 400 | 10 | 16: dustbin 13 litres
- SparkShield-400 | 500 | 630 | 16 | 20 | 24: dustbin 25 litres
You can place the dustbin on the floor or on a frame or small
platform. It is recommended to enlarge the distance between
the spark arrester and the dustbin by a duct Ø 200 mm/8 in.
Although it is possible the install the dustbin directly
to the spark arrester, the installation of a vertical
duct of >1 metre between the spark arrester and
the dustbin enhances fire safety. The larger the
distance to the dustbin, the safer.
For weight reasons we recommend to place the
dustbin on a small pallet to facilitate removal.
To install the dustbin, do the following.
WARNING
Due to the specific mass of sparks and other debris,
do
not
mount the dustbin in hanging position. This
goes for dustbin DB-13 and DB-25.
