UltraSieve Installation instructions
Please read these instructions before you start installing.
If you have some questions after reading this manual, please contact your UltraSieve dealer before you start installing to
prevent mistakes.
The UltraSieve can be installed in 2 ways:
1. Gravity (pond fed), equal to the water level in a direct connection with the bottom drain (and/or skimmer)
2. Pump fed, above the ground with a free flow back to the pond.
Below you see a schematic drawing of a possible gravity installation

Bottom drain
NOTE
: Make sure the edge of the UltraSieve is 1 cm higher
than the maximum water level
Make sure the UltraSieve is on an equal, level, underground.
The upper edge of the UltraSieve must be 1 cm above the
maximum water level
. Between the bottom drain and the UltraSieve we strongly advise you to use a slide valve to separate
the UltraSieve from the pond when necessary. The inlet of the UltraSieve is made of 110mm Polypropylene pipe so you can
use a PVC push fit fitting. Since the UltraSieve is made of Polypropylene you cannot make glue connections. The UltraSieve
has 2 inlets of 110 mm of which one is closed. If you want to use both inlets you have to cut off the end of the closed one.
Note: Do not install the UltraSieve directly in the soil! Make sure there is always enough room around the unit. When
there is pressure on the unit it will not work properly.

Pump connection
The pump outlet is made of a 2” PP male threaded connection. The UltraSieve is
supplied with a PVC fitting 2” fem. thread x 63mm solvent. Please use Teflon tape or
Loctite 5331 for the threaded connection. The maximum flow of the UltraSieve is about
30
m³ per hour.

Filter
Slide valve to flush the bottom drain direct to
waste without going to the filter.
In case the pump sucks in
air, because of the falling
water near the pump exit,
you can put the supplied
piece (±45 cm) of pipe
Ø50mm in the pump exit with
some Teflon tape. Then, the
pump will no longer take in
the water from the “turbulent"
part (A), but from the very
“quiet” part underneath the
float system (B).
