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.

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.
