► A constant water level in the pond is necessary for operating the gravity fed system. Tolerances of up
to -20 mm from the max. water level are permitted.
– If the max. water level in the pond is exceeded, water flows out of the Drum Filter Module via the
dirt channel until the max. water level is reached again.
– If the water level goes below the max. water level by more than 20 mm, it is not possible to achieve
optimum or fault-free operation.
► Install the OASE ProfiClear Guard refill system. The ProfiClear Guard refill system automatically
supplies water to the pond if the water level goes below the specified water level.

Information regarding pipes

► Use suitable pipes.
► Do not use any right-angled bends. Bends with a maximum angle of 45° are very efficient.
► Glue plastic pipes to ensure a permanent and reliable joint or use socket joints with clips to stop them
from coming apart.
► Standing water in pipes can freeze when there is a hard frost and cause pipes to burst. For this reason,
lay the pipes and hoses with a gradient (50 mm/m) to ensure that they can run empty.
► For gravity fed systems, it must be possible to shut off the supply from the pond and the return to the
pond for maintenance and repair work. For this reason, install suitable slide valves.
► In the case of the gravity fed system, the sum of the losses in the supply line must not exceed 7 mbar
(7 cm).
– Otherwise the water level in the filter system will go below the minimum water level during
operation. Optimum, fault-free operation will no longer be possible.

Connecting the inlet

Pump fed system
The Drum Filter Module has two 50 mm (2 ") connections. Connect one or two filter pumps depending on
the flow rate required.
► When two filter pumps are connected:
– Intermittent operation of the filter pumps is possible because the non-return valves prevent the
water from flowing back.
– Continuous operation of the filter pumps is possible without non-return valves. This reduces
pressure losses.
► You can additionally connect a UVC clarifier. (→ Fitting the UVC clarifier)
► The maximum flow rate per connection is 15000 l/h. The total flow rate of the system is to be limited
to 25000 l/h.
How to proceed:
 A, H
1. Undo the threaded cap with flat seal from the connection.
2. Screw the union nut with 50 mm (2 ") hose connector and flat seal onto the connection. Hand-tighten
the union nut.
3. Slip the 50 mm (2") hose of the filter pump onto the hose connector and secure with a hose clip.
Gravity fed system
 B, D
The Drum Filter Module is equipped with four DN 110 connections.
► Recommendation: Limit the flow rate to 8000 l/h per DN-110 inlet.
► Use suitable DN 110 pipes for connecting the bottom outlet and/or skimmer and the inlet.
► Secure the pipes so that fish cannot swim into them.
