D filling with powder and/or volatile materials
6.1.1 Modes of extraction of the polluted air
• SFE: extraction arm or ducting system
• HFE: extraction grid
6.2 SFE in kitchen extraction applications
This electrostatic air cleaner can remove, at a high
efficiency, small grease particles that pass the grease
filters. The SFE is designed to be installed in the
extraction ducting of a commercial kitchen
downstream of the extraction hood.
6.3 Oil drainer
It is possible to install an oil drainer in applications for
welding of oil-treated steel, oil mist extraction or
kitchen fume extraction in order to draw off
superfluous liquids from the oil collector.
6.4 Operation
The extracted contaminated air passes the pre filter
(fig. 2A) that takes out all larger particles. The pre filter
also ensures a proper distribution of the airflow.
After that, the air passes the ioniser (fig. 2B and 3B).
The contaminations in the air are electrically charged
by the high voltage (+10kV). These will then be
deposited on the earthed plates (fig. 2C and 3C) by the
collector voltage (+5kV).
The after filter (fig. 2D) is the last filtration step and it
also spreads the airflow.
There are a main switch (fig. 4A), a high-voltage
indicator (fig. 4B) and a reset button (fig. 4C) on the
control panel. Please contact your dealer if the high-
voltage indicator is not working.
Regularly check the functioning of the indicator when
using the product, since it indicates that the
electrostatic filter is properly charged.
When the product produces a crackling sound, then it
could be that the collector and/or ioniser are too dirty
and that both need to be cleaned. Switch off the
product with the main switch (fig. 4A). Wait for at
least 10 seconds prior to opening the door that
contains the filtration section. Subsequently, clean the
collector and ionisation sections using Plymovent EFC
while adhering to the instructions on the EFC
packaging. Check for touching collector lamellas.
Consult your supplier if the lamellas are bent!
After closing the door of the housing switch on the unit
by turning the main switch (fig. 4A) and press the reset
button (fig. 4C).
The distinguishing characteristics of the modular
mounting of the ionising and collector sections are the
very high separation efficiency (up to 98% of particles
larger than 0.1 µm), its low air resistance and the user-
0508080010/SFE-HFE/010111/G
friendliness while servicing the separate modules.
Repairs shall only be carried out by Plymovent or
Plymovent authorised staff. Maintenance contracts are
possible.
7 INSTALLATION
7.1 Installation SFE
Check that the suspension construction is adequate
prior to installing the product. Mount the SFE unit in the
ducting system. It can be supported by a suspension
bracket (fig 5A) as well as suspension by screw rods
attached to the top of the SFE unit (fig. 5B). It is
necessary to drill holes on the upper side for this
purpose. It is also possible to place the unit on the
ground providing sufficient space is allowed to use the
drain plug.
Please consult the electrical diagram (separate leaflet,
enclosed) when connecting the air cleaner to the
mains. Use suitable rubber or neoprene cable with at
2
least 4x1,5 mm wire area. Beware of possible
differences in the mains power supply.
The air cleaner can be stacked to a maximum of 4
units; the perforations and protrusions on the housing
can be used for this purpose.
7.2 Installation HFE
Check that the suspension construction is adequate
prior to installing the product.
Use the profiles (fig. 6E) when mounting the product
and attach the connection rings (fig. 6B), the lock rings
(fig. 6C) and the sliding nuts (fig. 6D) (all supplied with
the product) to the profiles. Use a suitable suspension
chain (fig. 6A) in this way of mounting. You can also
use the profiles (fig. 6J) together with screw rods M8
of suitable length. These should be mounted as
illustrated. The following parts are used in this case:
screw rod M8 (fig. 6F), self-locking nut (fig. 6G), lock
ring (fig. 6H) and sliding nut (fig. 6I).
Please consult the electrical diagram (separate leaflet,
enclosed) when connecting the air cleaner to the
mains. Use suitable rubber or neoprene cable with at
2
least 4 x 1,5 mm wire area. Beware of possible
differences in the mains power supply. The position of
the contact bridges may need to be changed as well as
the connections inside the motor compartment. When
connecting, pay attention to the direction of rotation of
the motor!
Ensure at all times that the setting of the thermal relay
corresponds with the nominal current rating of the
motor for the applicable power mains. This rating is
given on the motor identification plate.
