Commissioning and Service
6.1 Commissioning
Before putting the system into use the filter sieve
surface is to be thoroughly cleaned with absolvent
based cleaning fluid. Alternatively the filter sieve may be
cleaned in a dish washer (40° - max. 60°). Any dirt that
gets into the filter housing during the assembly must be
thoroughly removed.
The filter sieve functions only in one flow direction due
to the designed structure, the direction is marked on the
metal ring with an arrow on the inlet side. When
installing the filter cartridge pay attention that the joint
seam of the sieve surface is positioned upward.
6.2 Service
The complete system is to be inspected at least every 3
months for leakage, cleanliness stability. To ensure the
expected water yield is delivered, it is important to
inspect and to clean the filter sieve at regular intervals.
When carrying out a regular service of the integrated
filter it is also required that the overflow siphon is
checked and cleaned.

Efficiency / Performance
In the case of normal rainfall of 150 l/s, the
amount of water to be harvested from a roof
area of 150 m² is approximately 2.25 l/s, that is
equal to 135 l/min.
The SUPRA-Filter has with this flow volume an
efficiency factor of 99%, this means in real terms
that a tank with a volume of 4000 l will be filled
in approximately 30 minuets.
8.
Mounting of cleaning unit
The brass jet ¾“ is to be inserted in the provided aperture
at the inlet side of the filter housing and fixed with the
brass bend from the outside. Afterwards the brass hose
nozzle is to be screwed on with a union nut and connected
with the hose (provided by customer). The hose is
conducted through the empty conduit to the pump and
linked with the pressure line on the pressure side after a
cut-off cock.
