Connecting the drum filter
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 severe frost and cause pipes to burst. For this
reason lay the pipes and hoses with an incline of 0.6 in/ft (50 mm/m) to ensure they drain com-
pletely.
• 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.
• For the gravity fed system, the sum of the losses in the supply line must not exceed 0.1 psi
(7 mbar) or 2.8 in (7 cm).
– Otherwise the water level in the filter system will drop below the minimum water level during
operation. Optimum, fault-free operation will no longer be possible.
• In the gravity fed system the ideal flow rate per supply line is between 1585 gph (6000 l/h) and
2245 gph (8500 l/h). Provide sufficient supply lines.
Connecting the inlet
WARNING
The container is made of glass fiber reinforced plastic. Hazardous glass fiber particles are released
during drilling or sanding.
Always wear a suitable respirator mask when drilling or sanding.
Pump fed system
The filter system is equipped with an inlet ∅ 2 in (∅ 50 mm) for the filter pump. If necessary, the con-
nection set (18798) can be used to install a second inlet for an additional filter pump. This does not
change the flow rate of the filter system.
• Markings for the through holes of the second inlet are provided on the container wall. Ensure that
the through hole is cut out.
• Leave any unused inlets closed.
• You can also connect a UVC clarifier. (→ Installing UVC clarifiers)
How to proceed:
1. Undo the threaded cap with the flat seal from the connection.
2. Screw the union nut with the hose connector ∅ 2 in (∅ 50 mm) and the flat seal onto the connec-
tion. Hand-tighten the union nut.
3. Push the hose ∅ 2 in (∅ 50 mm) of the filter pump onto the hose connector and secure it with a
hose clip.
