3. General
3.1 Description of the drum filter
The Drumfilter consists of a drum sieve that is driven
by an electric motor. Control electronics and a waste
pump are also supplied. The drum filter has the job of
filtering and discharging suspended substances, dirt
particles and algae residue
This drum filter is a product that can only be used in
fresh water. The filter has been designed for use with
ponds.
The water to be filtered flows (by gravity or through
a pump) into the inlets in the drum. On the inside of
the drum, the dirt remains behind because of the
mesh that is stretched over the drum. As the mesh
becomes dirtier, less water flows through the drum.
The water level after the drum drops (with regard to
a gravity system) and a sensor that is present there
that measures the water level, subsequently, switches
the electronics. The electronics sends a signal to the
drum motor and waste pump. The drum rotates and
the rinsing pump operates the nozzles with high
pressure that clean the mesh of the rotating drum. This
wastewater is collected by a duct in the drum and flows
outside through the duct to, for example, the sewer.
After the sensor detects that the water level is
sufficient again, it switches the electronics off again.
The drum will stop turning and the pump will stop
spraying water to the nozzles.
3.2 Warning Notes
Only appropriately trained personnel may commission
and maintain this drum filter. These personnel must
be familiar with international accident prevention
regulations. Connection and adjustment must be in
accordance with current electrical regulations.

4. Use of the drum filter
Only use the filter when no body parts are in
contact with the water! Before you reach into the
water, always disconnect the filter from the power
supply. Compare the electrical specification on the
type label of the device with the specification of
the power supply. Make sure that the device is
connected to an ELCB (earth leakage circuit
breaker) with an assigned leakage rating of max.
30 mA (DIN VDE 0100T739). Only operate the
device on a correctly installed power plug.
Keep the power plug and the wiring dry! Make
sure that the cables are protected to prevent
damage and consequent short circuits.
THE WIRING OR THE POWER PLUGS MUST
NOT BE CUT. DOING SO WILL IMMEDIATELY
INVALIDATE ALL WARRANTY AND LIABILITY
OF THE MANUFACTURER.
Only use wiring, installations, adapters, extension
cables and connection cables with grounding-type
plugs, which are approved for outdoor usage (DIN
VDE 0620) with sufficient cable diameter. Do not
pull on the wiring of the devices or use the wiring
to carry the devices! If a wiring is damaged or
broken, the device may no longer be used! Take
care that power plugs never falls into water or
gets wet. If a plug gets wet,
it must be opened by a professional and cleaned
by purging with demineralised water. Protect
plugs and the wiring from heat, oil, UV light and
sharp corners. The manufacturer is not liable in
any way for any damage caused by improper
installation or by the carelessness of the user or
installer.
The wiring may not be modified or replaced.
Electrical installations on garden ponds must
always comply with national and international
directives and requirements. Never open the case
of the device(s) or of the appending parts if this is
not explicitly suggested in the user manual. Never
apply technical modifications of the device(s).
Only use original spare parts and accessories.
Only allow authorised customer service facilities to
conduct repairs. Never use the filter with any
other liquids than water.
5. Fields of application
The Drum filter is suitable for freshwater and
brackish water.
Temperature of the water: +4 to +40 °C.
Environment temperature: +2 to +50 °C
Protection class control box: IP54.
6. Installation/Fitting
CAUTION:
Before you install the filter, read the manual
carefully. Damage caused because the manual
was not read thoroughly does not fall under
warranty.
When unpacking the filter, check if all parts have been
delivered completely and undamaged. Any damage
detected must be reported to your retailer within 24
hours of purchasing the filter. Please check the device
for damage before you operate it. Do not use the
device if it is damaged. Please inform your retailer
immediately. If the device is used despite being
damaged, any warranty and liability will then be
invalid.
During the course of the installation, the device may
not be connected to the power supply. Remove all
plugs from the electric sockets and make sure that
the filter cannot be switched on. To avoid injury,
make sure that your hands or fingers cannot reach
the rotating parts of the filter when it is connected to
the power supply.
7. Operating the filter
NEVER USE THE DEVICE WITHOUT
WATER THROUGHPUT.
7.1 Placing the filter
You must carefully follow the instructions below to
work safely and prevent damage to the equipment.
• Ensure that the substrate is levelled and sufficiently
robust; the filter weighs more than 400 kg when
operational. A concrete slab is the preferred option.
• When checking if the waste pump or drum motor is
still working, the lid must always be closed. Never
put your hands in the filter or try to stop the drum
with your hands.
• The waste pump must always be below the water
level before it is switched on. If not, it will be
irreparably damaged because of running dry or
overheating. The warranty will not cover damage to
the waste pump because the pump has run dry.
• The electronics must be suspended in a dry and
appropriately ventilated room. The temperature of
the room where the electronics is suspended must be
between 2 and 30 °C. If the temperatures are higher,
the electronics cannot handle its own heat properly
and this may lead to damage.

Ilex Filtration Biodrum 20 [phone]

Subject to typesetting and printing errors
• The electronics contain components that switch
and must be suspended in a failure free room.
Specific pumps or UV units may have a negative
impact on the operation of the electronics.
• The filter must be protected against freezing when
there is frost. If the filter is put out of service, all
pipes must be emptied. If the filter stays in service,
the pipes for the rinse water must be protected
against freezing. Damage caused by water freezing
is not covered by the warranty.
7.2 Gravity connection
If water flows into the drum due to gravity, the
maximum water level must be correctly aligned with
the drum. The maximum and minimum water levels
are indicated on the inside of the filter and must be
between these values and, by preference, as close
as possible to the maximum level (see the figure).
The filter has 3 x 110 mm inlets and 1 x 110 mm
outlet. In addition, there is a connection for the
flushing pump.
Attention:
It is essential that sufficient water arrives in the
filter when installing on a gravity basis to ensure its
correct operation! If insufficient water arrives
because the system has been installed incorrectly,
you run the risk of the waste pump running dry and
that the rinse cycle is switched on very frequently.
It applies as a general rule that approximately 10
m3/ hour can flow per 110mm of pipe in a gravity
set-up. This quantity, however, will depend on the
length of the pipe and the maximum height
difference between the pond water and filter. In
some cases, for example, only 3m3/hour can flow
per pipe.
Therefore, pay attention to the following
issues for a maximum flow per pipe:
The pond water level may not drop too much. If the
pond water level drops 1cm, the flow rate can
already drop by 1 or 2m3/hour per pipe. There is a
risk that insufficient water arrives in the filter when
there are considerable fluctuations in the pond
water level (due to evaporation, water change or
when you rinse the filter). If your pump pumps
away more water than arrives in the filter, the drum
filter will be emptied, the sensor will run dry and the
filter will start the rinse cycle.
If the supply pipes are long and with many bends,
there are many friction losses and much less can
arrive instead of 10 m3/hour per pipe system.
Inlets that are not used must be plugged.
Discharge of dirt:
The dirt is sprayed off by the mesh nozzles into the
rinse duct. The rinse duct can be connected to the
sewer system or discharge drain directly.
Pond return:
The pump must be connected to a 110mm discharge. If
required, use a flexible connection for a good transition
to your pump. A flexible connection will reduce
vibrations.
Make sure that you never install a larger pump than
recommended for the filter. If the pump you have
selected is close to the maximum of the filter, you
must ensure that sufficient water arrives and that the
filter is not suctioned dry.
7.2.1 Sensor setting for the rinse cycle
The sensor will already have been installed for use as a
gravity sensor and in such a way that it will operate
correctly in most situations. You must, however, check
its correct operation after installation and adjust the
float as correctly as possible.

Ilex Filtration Biodrum 20 [phone]

Subject to typesetting and printing errors
The floats act as a break contact. If the top float is
‘dry’, the water level behind the drum is too low
because the mesh is clogged: the pump pumps
away more water than is being supplied through
the bottom drains/skimmer. The electronics will
switch and the filter will rinse.
The top sensor can only be adjusted correctly when
the system is commissioned.
The water level for the drum will then drop. Now,
the top float must not be set lower than 10 cm
below the water level inside the drum. By
preference, this difference level between the inside
and outside of the drum should not be more than 8
cm during operation. If the difference in level is
too great, the drum will turn heavily and the load
exerted on the drum filter motor will be high. If the
The pressure side of the pump must be connected
to the pipe to which the nozzles have been
connected. Ensure that the connection on the
pressure side is good and properly sealed because
the pressure of the pump is high (up to 5 bar). Do
not therefore use sewer PVC but high-pressure
PVC that can withstand at least 10 bar.
The waste pump plug must be connected to the
control electronics in the ‘RINSE PUMP’ plug
connection.
difference in level is too little, the rinse frequency
will be too high.
7.2.2 Safety float
The bottom float is for protection. If the water level
continues to drop, the system will be switched off
by the electronics. If the system pump and UV unit
are also connected on the plug connections for this
purpose of the electronics (‘PUMP’ and ‘UV-C’), they
will also be switched off. This will ensure that
neither the pump nor the UV will be without water.
Waste pump connection
7.2.3. Connecting flushing pump
The waste pump is already included with the Drum
and it is positioned outside the filter. There is not
already a connection for the suction side of the, but
you can create a connection at a different place as
long as the supply of the rinse water is installed
after the drum filter so that the waste pump has
clean water and the nozzles cannot be obstructed.
When the water level is again OK, everything will
again be switched on with a small time delay.
You can connect the float plug to the female plug of
the control electronics. Pay attention to the recess
of the plug connection.

Ilex Filtration Biodrum 20 [phone]

Subject to typesetting and printing errors
7.2.4 Connecting the motor drum filter
The plug of the drum filter motor must be connected to
the control electronics. Use the 'MOTOR DRUM FILTER'
plug connection for this.
7.2.5 Rinse frequency
Ensure that the rinse frequency is not too high. If the
drum is being installed in an existing system, the rinse
frequency will be high during the first days/weeks
because the pond will be ‘cleaned’. The rinse frequency
will also be considerably higher when the weather is hot
(more food and more algae growth) than during colder
weather.
Other reasons why the rinse frequency is (too) high
include:
• The pond pump is too large.
• Too little water arrives because the pond water level
is too low or the supply system is incorrect from the
pond such as pipes that are too long, too few pipes
or the pipe diameter is too small.
• The top sensor is set too high.
• The mesh has become completely clogged because
of, for example, bacteria.
• The pressure of the waste pump is too low.
• The waste pump flow rate is too low.
A rinse frequency that is too high will lead to a high
rinse water consumption.
7.2.6 Control electronics
The control electronics has a protection class of IP54.
Electrical systems must always meet national and
international requirements/directives. Never open the
housing of the electronics. The electronics are sealed
and the guarantee will be null and void if the seal is
broken. Never make technical changes. Only authorised
dealers may perform repairs.
The control cabinet must be connected to an approved
earthed power socket. The electronics must be installed
vertically. The electronics may not be installed in the
rain without protection.
At most, 1000 W in peripherals may be connected for
each connected side. Every side is fused with a 5 x 20
mm 5 A/250 V (delay) fuse. A higher rated fuse may
never be used when the fuse is replaced.

7.3 Connecting a pump-fed system
The SuperDrum Combi Bio can also be connected
as a pump-fed system: the water is pumped into
the filter by the pump. Openings that are unused
must be plugged.
7.3.1 Float installation
You must install the float in front of the drum section
for this (at the inlet). Additional holes have already
been provided in the housing for an easy installation.
Attention:
The float must be installed upside down because
the switching will also work in reverse order. If the
water now rises in front of the drum filter, it will be
contaminated and the rinse cycle must be
activated. If now the highest float goes up in the
upside down state, the system must switch off
because, if not, the water will flow directly to the
drains and your pump will be pumped dry via the
rinse duct. The safety float must therefore be
installed at the correct height in such a way that
the system switches itself off before the water
overflows into the rinse duct.
As extra protection, the 2 plugs of the top plugged
holes can be removed so that the water flows further
unfiltered during an emergency and there is no risk that
water is pumped directly into the rinse duct.
7.3.2 Connecting the pond return
The return to the filter must first go up to determine
the required height within the filter.
This should not be too low because of the present
biofilter material. It may not be too high either
because then the rinse frequency of the filter will
become too high.
The drum must also be aligned when in operation. A
rinse cycle must be started when the water level
difference before and after the drum is approximately
8-10 cm. Ensure that the vertical part stays open
when up so that there is no siphoning and that the
drum filter is suctioned dry because of it.
If you want to pump more water than 1x 110mm pipe
can handle at gravity, you need to make extra
passages. You can also connect the return to the
pond with a larger diameter pipe.
8. Maintenance and cleaning
The SuperDrum Combi Bio requires little
maintenance. The following maintenance and
checking activities are, however, required to ensure
a good operation:
• Check the correct operation of both floats on
a monthly basis.
• Perform a manual rinse and check whether the
nozzles are spraying correctly on a monthly
basis. A nozzle can be clogged or limescale may
build up. The waste pump may also supply less
pressure. If required, clean the nozzles.
• Clean the sieve element as required using a
strong acid (30-35% hydrochloric acid). A biofilm
or limescale may build up in due course, which
means that the rinse frequency will increase
significantly. Observe the safety instructions
when cleaning using acids. Use protective clothing
and safety goggles.
