CPF-280/CPF-500
Part Name
Explanation
A
Water inlet
The pump is connected to the water inlet via a pressure hose.
B
Whirl system
The water permeates through the bio-filter materials due to the cent-
rifugal and gravitational forces.
C
Mechanical filter
Dirt particles are retained on the surface of the sponge filter before
the water flows towards the inner of the filter.
D
Biological cleaning
Microorganisms settle on the filter sponge pores. The blue and the
yellow filter sponge differ in size and density. This generates zones/
areas through which the water flows at different speeds. In the
zones/areas with a high flow speed (blue filter), mainly microorgan-
isms settle that convert ammonium to nitrate. In the areas in which
the water flows faster (yellow filter), mainly anaerobic microorgan-
isms accumulate that reduce the nitrate to nitrogen.
E
Pre-cleaning of the pond
water
When the water flows out, it is shortly exposed to the UV radiation
emitted by the UV lamp. As a result, germs, bacteria, and algae are
destroyed. The water circulates when flowing through the filter from
inside outwards.
F
Water discharge with
flow display
The cleaned water flows back into the pond.
G
Hose tails for rinsing water when on cleaning (CPF-180/CPF-250)
Flow indicator (CPF-280/CPF-500)
Hose tails for rinsing water when on cleaning (CPF-2500-5000-10000-15000-20000-30000)
H
The function switch changes between “filtration” and “clean filter.”
I
Flow indicator (CPF-
180/CPF-250)
When there is too much dirt on the sponge, the turbidimeter will
change from green to yellow to warn you to clean the sponge.
