2. Product description
The drum filter consists of a PP basin containing a PP drum with
mesh. The drum is pump-fed and installed beside the pond.
The inlets are below the water surface level, and the dirty water
is pump-fed through the floor drains or skimmers into the first
filtration chamber. On the outflow side, the water flows through
a slotted plate into the moving bed. Because the dirty water
flows through the drum, contaminants in the water cling to the
interior of the drum. As a result, less water can flow through the
mesh and the water level on the inside of the drum rises. The
water level meter detects this and initiates the flush cycle. This
cycle consists of activating the drum motor and spray pump.
This causes the drum to turn slightly more than one full rotation
and the sprayers flush the mesh clean. The flush water then
flows into the sewage along with the waste. The cycle repeats
as often as necessary.
3. Assembling the filter
The housing of the filter consists of a PP basin with one
partition. The partition is fitted with a silicone sealing strip at
the flange which separates dirty water from clean. There are
also 4 holes in the partition which are covered with a cap. In
case of a breakdown in the drum control, the covers can be
removed to enable the water to bypass the drum and flow past
it without being filtered. This enables you to still use the
biological filtration segment.
The basin is fitted with a removable waste drain. This can be
removed from the interior of the drum, which saves you the
trouble of having to disassemble the drainage line. The inclined
surface accelerates the water flow, causing the waste to be
carried along with it into the drain. There are also 4 brushes
installed on the inside of the drum which sweep away any algae
or other coarse particles that cling to the drain. The drum filter
is fitted with a removable spray tube made of PP, which is
equipped with flat jet nozzles. The sprayers feature a quick-
release system, making them easy to remove for cleaning. The
water level meter in the basin consists of 3 electrodes, 1 flush
level, 2 high-level safeties and 1 common electrode. The water
level for initiating the flush cycle is adjustable. Inside the basin
is a high-pressure submersible pump which supplies water to
the sprayers under high pressure during the flush cycle.
The drum motor is installed in a water-proof compartment inside
the biological filtration section. The shaft is enclosed by a
retaining ring in the installation plate. The shaft connects to
the drum via a flange with a pipe. To remove the drum, you can
simply detach this pipe-shaft connection, after which the drum
can be taken out. You do not have to disassemble the motor to
do this. The screens can be removed by detaching the tension
straps and unscrewing the cover panel to remove it.

the current on any water-bearing equipment before you come
into contact with the water.
5.2 Pacemakers
The cover has a magnetic switch. The magnetic field may interfere
with pacemakers.
5.3 Guidelines for electrical installations
The electrical installation must be carried out in accordance
with all national legislation and may only be performed by a
nationally certified electrician. A person is considered an
electrician if they have the appropriate training, knowledge,
experience and certification, and are capable of assessing and
conducting the necessary work. The job of an electrical specialist
also includes recognising any possible hazards and complying
with all applicable regional and national standards, regulations
and provisions of law.
• For your own safety, always consult a professional electrician
in case of any problems.
• This system can only be connected to a power supply that
matches its electrical specifications. All specifications for
this system can be found in this user manual.
• The system must be protected by a residual current device
with a fixed residual current of max. 30 mA.
• Use only extension cables and power dividers that are
splash-proof and whose cable diameters are the same as
the ones supplied with the system.
• Do not allow the plug connections to come into contact
with water or moisture.
• Connect the system only to a power outlet that has been
installed according to industry standards and does not
contain a dimmer.
5.4 Safe use
• Never use this system in connection with faulty electrical
cables or a defective housing.
• Never pull on the cables to adjust the placement of the
system. Ensure that the electrical cables are not pulled
tightly.

6. Placement and setup
If you plan to install this system in a way that deviates
significantly from the recommendations in this user manual,
allow for a specialist to inspect the installation to ensure that
all technical specifications have been met.
The combi drum filter must always be placed in a level position.
The bottom of the filter must be completely supported. It is
recommended to place the system on a flat cement floor. When
positioning the filter, ensure that there is adequate space on all
sides so that you have room to perform maintenance. In order
for the filtration system to work properly, the filter must always
be placed above the water level.
Any greater deviation will result in an inaccurate measuring
of the water level. If the water level rises by more than 2 cm,
the water will overflow via the duct into the sewage system.
To prevent this, position the short electrode so that it is 1 cm
below the surface on the upper side of the drain. To maintain a
constant water level, you can install an automatic filling station
with overflow function for your pond.
For optimal water flow, use all 4 outlet connections. It is
recommended to use flexible rubber sleeves and joints when
connecting the water lines. These can compensate for small
dierences in dimensions and also absorb vibration.
Install slide valves or ball valves in front of and behind the filter,
so that the filter can be emptied during maintenance.
The drainage duct can be connected to a sewage connection
with a 110 mm diameter. Make sure that the duct is positioned
at an adequate incline. It is recommended to install a pipe with
a flexible rubber sleeve. These can compensate for small
differences in dimensions and also absorb vibration. They can
also be detached to remove the drainage duct.
Always use high-quality pipes with an adequate wall thickness.
Ideally, use 45 degree elbow connectors.
Lay the pipes at a downward angle so that they can be fully
emptied during the winter to protect them against frost.
Note! Electrical shock hazard. Use of this electrical system or
installation in connection with a (swimming) pond may result
in severe injury or death.
Only use this system in accordance with national and regional
regulations.
Always use suitable transport and lifting equipment when
transporting and assembling this system.
6.1 Connecting the control box
Ensure that the control box is not plugged in to the mains
power supply! Open the control box!
Hang up the box on 4 screws aligned with the grooves on the
back of the box. Space between the holes in the wall: w = 280 mm
x h= 251 mm. Remember that the length of the cable for the
electrical equipment is 3 metres. Be careful when opening the
box and remember that the screws you must loosen to open
the door should not protrude when you turn the box open. The
same goes for when you close the box.
6.2 Connecting the electrodes and water level meter
Ensure that the control box is not plugged in to the mains power
supply! Open the control box!
Turn the gland caps on the underside of the box and slide them
over the corresponding cable. Run the cable through the
cable gland into the box, leaving adequate length. Then twist
the gland caps closed again. Connect the electrodes as shown
below using a suitable screwdriver. The labels on the electrodes
match the codes on the connection inside the box.

7. First use
Before using the combi drum filter for the first time, it is
advisable to thoroughly clean the pond manually and flush the
pipelines if possible. The reason for this is to prevent the newly
started filter from immediately experiencing an interval break-
down.
Note! Electrical shock hazard.
• Always switch o the current to the system before coming
into contact with the pond water.
• Secure the system to prevent it from unintentionally being
switched on.
• Never connect the system to a power supply that is fitted
with a dimmer.
• Do not use the system in combination with a switch that
has a timer function.
• Only switch on the control box if the submersible pump
is below the water level and the electrodes are below the
surface.
7.1 Sequence for first use
• Remove the cover from the filter.
• Check all the water inlet and outlet connections.
• Check the line from the pump to the spray tube to ensure
it is hand-tight.
• Open the valves on the outflow side.
• Open one valve in the in-flow line.
• Switch on the pump.
• Adjust the flow of the pump to point downwards in case
the desired water level quickly reaches the high level.
• Check all the water inlet and outlet connections again.
• Plug the connectors into the corresponding power sockets:
The plug for the spray pump goes into the power socket labelled
"spray pump".
The plug for the drum motor goes into the power socket labelled
"drum motor".
The plug for the water pump(s) goes into the power socket
labelled "pond pump".
Any additional components connect into the power socket
labelled "spare".
Please make sure that the power sockets can support a total
output of 2500 W from "pond pump" and "spare" combined!
7.2 Adjusting water level meter
The water level meter consists of 3 stainless steel electrodes:
• The "high-level" electrode (the short coated electrode)
• The "flush-cycle" electrode: the short coated electrode
• The common electrode: the long uncoated electrode
The flush-cycle electrode is set to the highest level by default.
This means that the flush cycle is initiated when the water level
drops by approximately 90 mm before the low level is reached.
If you would like for the flush cycle to take place sooner, you
can unscrew the cable gland and place the electrode lower.
Afterwards, tighten the cable gland again.
Note! The other two electrodes do not have an adjusting function.
7.3 Flush cycle
If the pond's water quality is such that the flush cycle lasts less
than 3 minutes, then the flow into the water inlet must be reduced
to ensure that the cycle lasts for more than 3 minutes. After the
contamination in the pond has decreased, the throttling in the
drainage duct can be gradually reduced as long as you allow
for the flush cycle time mentioned above.

is connected
- When the flush cycle is complete, the "Flush" LED
switches o again.
- Remove the cover and check whether the water level
has reached the required operating level again
- Repeat the steps above if necessary
- If this continues to happen, you must decrease the inflow
capacity to the filter or increase the outflow capacity
from the filter.
Door Error:
The cover (contact) is not closed. The cover is not installed or
is not closed properly.
- The water pumps are switched o.
- No flush cycle is possible.

• Open the box
• Check whether the DR+ and DR- cables are properly
connected
Interval Error:
This occurs when 50 flush cycles have occurred in a row with
a pause of less than 3 minutes between each cycle. This may
occur when the water is heavily contaminated.
- The water pumps are switched o.
• Set the flush-cycle electrode to the highest level. Now, a
flush cycle will be initiated later.
• Check the outflow lines to see whether they are clogged.
• Check the sprayer heads and clean them if needed.
If this does not help, reduce the incoming flow until the most
heavy contamination is eliminated.
7 Auto Mode LED:
The LED glows then the system is in automatic mode.
8 Manual Mode LED:
The LED glows when the system is in manual mode.

12 Combi drum 55 (pump)
9 LEDs for the selected time interval:
Depending on how dirty the water is, you can choose between
5 dierent flush times.
The normal flush time can be used for average water conta-
mination. If the pond is very clean and hardly contains any
contaminants, such as in the winter time, you can switch to the
"eco" or "smart" setting. This reduces your water consumption. If
the water is heavily contaminated and you would like to flush
the screen more frequently, you can choose the "super" or
"turbo" setting.
You can change the selected flush times in Manual mode by
pressing "Change Flush Time".
The sprayer does not begin spraying until 1.5 seconds after the
motor starts. This ensures that only the soiled portion of the
screen is sprayed.
The Eco setting has a spray time of 5.5 seconds (quarter turn).
The Smart setting has a spray time of 8 seconds (half turn).
The Normal setting has a spray time of 11 seconds (1 turn).
The Super setting has a spray time of 22 seconds (2 turns).
The Turbo setting has a spray time of 33 seconds (3 turns).
Make sure that there is an interval of at least 3 minutes between
flush cycles, otherwise the drum will experience an interval error.
Confirm your choice by pressing "Change Mode". Your choice
is now saved. In manual mode, you can change this again if you
wish.
10 Safety Switch:
If the 'Safety Doorswitch E' is switched on, the system is supplied
with electrical current. After you use 'Safety Doorswitch E', the
system will always start in Manual mode. If you want to open
the control box, you must switch o 'Safety Doorswitch E' or
else the door cannot be opened. This is an additional safety
feature.
10. Cleaning and maintenance
Note! Electrical shock hazard! This can result is severe injury
or death.
When performing cleaning and maintenance, always take the
following measures:
• Always switch o the power supply and secure it from
being accidentally switched back on before you come into
contact with the water or perform any maintenance work
on the system.
• General cleaning - 1x each month:
- Switch o the "Main switch" and unplug the system from
