– G3 to F9 Filtration Class
Filter inserts are inserted in separate fields of the filtering wall which
can be pulled out from the air-handling unit. To replace the filter
insert, turn the securing locks by 90°, and replace the filter insert
with a new one. Before inserting new filter inserts, check the sealing.
Check the filter insert centring, and push the filtering wall back into
the air-handling unit.
Active Carbon Filter Cartridge Check
There is no pressure loss in the active carbon filter cartridge due
to fouling.
The most effective way to check the saturation of filter cartridges
is by weighing them. After reaching their maximum capacity, i.e.
their net weight has increased by about 20% to 50 % (depending
on the type of carbon and filtered gas; ask the manufacturer for
precise information), the carbon cartridge must be reactivated. If
this limit is exceeded, the filtering efficiency will be diminished. The
total weight of the clean standard, 450 mm long, active carbon
filter cartridge is 2500 g, the weight of the filling is 2000 g (max.
recommended increase in weight is 400 to 1000 g).
As the complete cartridge must be reactivated, it is advisable to
possess a spare set of filter cartridges.
Subsequent intervals of cartridge replacement can be scheduled
on the basis of the above-mentioned weight measurement.
Checking the Exchangers (Heaters, Coolers)
Be very careful when cleaning the exchanger‘s vanes to avoid
mechanical damage.
It is important to check the air-venting of the exchangers.
Permanently check the functionality of the condensate draining
system (coolers).
Important note:
If taking the exchanger out of operation during
the winter season, the water must be completely drained out of the
exchanger, and possible water residuals must be removed, e.g. by
flushing the exchanger with pressurised air; or the exchanger must
be filled with a safe antifreeze solution of water and glycol. The water
residuals can freeze in the exchanger and damage the copper pipes.

The 96 mm long wall of frame filters can be removed by pulling the
frame edge out and then realising the sheet steel retaining clamps.
The replacement filter can be installed in the reverse procedure: Care-
fully bend (without permanent distortion) both edges of the vertical
paper frame, install the clamps and place all the filters between the
bars, first the lower row then the upper row, until they are completely
seated. It is advisable to perform regular inspections of the frame
filters, especially if high air humidity is present or if it fluctuates
through the day. Unsuitably low pressure loss read on the manometer
can indicate frame distortion. If this happens, a physical check of the
filters is recommended.

The required filtration class must be specified after the mark xx (04, 05, 07, 08, 09 – standard length of bags/ K5, K6 – shortened length of bags)
** the value in the brackets parentheses applies for M5 filters (marked K5) and M6 (marked K6)
XP 04, XP 06 and XP 10 Air-Handling Units
To remove the filter insert, turn the screws (XP 04 - 2 screws; XP
06 and XP 10 - 4 screws) counter-clockwise using Allen wrench # 6,
release the fixing clips and pull the filter insert out of the groove (see
figure # 28). Reinstall the filter inserts in the reverse way.
