Connecting the ductwork
Type TFM particulate filter modules for ceilings are
supplied with different spigots as follows:
Top entry circular spigot
The spigot has a lip seal and is suitable for circular
ducting in accordance with EN 1506 or EN 13180.
Connect the duct in such a way that the connection
is tight.
To protect the filter elements once installed as much
as possible from excessive contamination, proceed
as follows when you install the ventilation system:
Keep the ducts clean when you install them.
If you have to interrupt the installation proce-
dure, protect all openings from the ingress of
dust.
If necessary, clean the ducts before you com-
mission the ventilation system.
Commissioning
General information
Before you start commissioning:
Check that the filter casings are correctly
seated.
Remove protective film, if any.
Ensure that all filter casings are clean and free
from residues and foreign matter.
Prime the ventilation and air conditioning
system for 24 hours before you insert the filter
element.
Volume flow rate balancing
To adjust the ventilation and air conditioning
system, you first have to carry out volume flow rate
balancing for each particulate filter module. Volume
flow rate balancing is required before initial commis-
sioning.
Inserting filters
Do not unpack filter elements until you are
ready to install them.
Do not touch the filter, hold it by the edge only.
Check filter elements for any damage; replace
damaged filter elements.
Insert only suitable Mini Pleat filter elements
with a flat seal or fluid seal.

1.
Remove the clamping frame (Fig. 5/3) from
the particulate filter module. To do so,
loosen the clamping screws (Fig. 5/4), then
press the release buttons (Fig. 5/5) in;
remove spacers, if any (spacers are used to
fix the clamping frame during transport of
the unit).
NOTICE!
Do not damage the filter.
Handle filter elements with care and hold them
only by the edges.

Set the filter element (Fig. 5/2) with the seal
(Fig. 5/1) facing upwards into the clamping
frame.
