Gravity fed system
The filter system has three inlets ∅ 4 in (DN 110). If necessary the connection set (19005) can be used
to install a fourth inlet of the same size. This increases the maximum flow rate of the filter system to
8718 gph (33000 l/h).
• Markings for the through holes of the fourth inlet are provided on the container wall. Ensure that
the through hole is cut out.
• Recommendation: Limit the flow rate to 2245 gph (8500 l/h) per inlet.
• Use suitable pipes for connecting the bottom outlet and/or skimmer and the inlet.
• Secure the pipes so that fish cannot swim into them.
Installing UVC clarifiers
Pump fed system
The Bitron UVC clarifier is fitted to the filter container. This does not change the flow rate of the filter
system.
• It is necessary to remove a screen element to access the sealing plugs. (→ Removing/fitting a
screen element)
• For operation with two filter pumps, one filter pump is connected to the UVC clarifier, the other to
the inlet. (→ Connecting the inlet)
A non-return valve is installed in the connection for the filter pump to prevent water from re-
turning. If a filter pump each is to be connected to the Bitron and to the connection for the fil-
ter pump, the pump on the connection for the filter pump can be switched on/off as required
without any problems.
