Introduction
The UltraSieve is a pre-filter to filter waste solids from the water. This technique is based upon the sieve-bend. A sieve-
bend consists of hundreds of sharp stainless steel profile wires with very small slot openings where the water can go
through but the solids stay on the sieve bend (see picture below).
In practice it works as follows:
The water enters at Aand will go upwards and fall over the “auto-adjustable” dam (B). The water goes through the
sieve bend (C) and the waste solids will slowly go down to the waste area (D). At the waste outlet of the filter (E) is a
90mm sliding valve to easily wash away the waste with water. When the water in the tank underneath the sieve-bend
will not be pumped away fast enough the water will raise which makes the floating system (F& B) go up to reduce the
incoming water flow. The pump will be connected to the fitting 2” x 63mm(G). You can use a self-priming pump like a
Whisperflo or Speck or a submersible pump that can be used out of the pond like the Oase and Messner series.
An extra advantage of this pre-filter is that the water will be provided with extra oxygen,
when it goes through the slots.

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
30m³ 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).

The auto-adjustable dam with floating device
The UltraSieve has a floating system to prevent the water in the area under the
sieve from rising above the level of the sieve for low speed pumps and also to
prevent the water from going too low to be primed for high speed pumps. The
floating device can be installed at 3 different levels. You only have to do this
once when installing the UltraSieve or when you change pumps.
Stainless bolts (10 millimeter) to adjust
the height of the floating device
Procedure: loosen the 10mm bolts a little bit in order to move the floating device. Note: do not remove the
bolts completely, a few millimetres is enough!
Push the floating device to the left in order to move it in the vertical opening. Choose one of the 3 levels and
push the device to the right position. Fasten the bolts again. You’re done.
Level 2
This level gives the dam its middle
length, suitable for pump speeds to
± 12-16m³/hour.
This length prevents the water from
flooding the screen but also from
going too low which causes priming
problems.
Level 3
This level gives the dam its
minimum length, suitable for pump
speeds >18m³/hour.
The minimum length of the dam is to
have a high water level under the
screen to prevent a high speed
pump from priming air.
Level 1
This level gives the dam its
maximum length, suitable for pump
speeds to ± 6-10m³/hour.
The maximum length of the dam
prevents the water level underneath
the sieve from going too high for low
speed pumps.

Waste outlet
The waste outlet is provided with a 90mm Valterra slidevalve for easy
clearance of the waste. Supplied with the filter is a small PVC pipe that
fits around the slide valve. You can glue this piece of pipe around the
slide valve the obtain a 110mm external pipe diameter for standard
waste pipe connection.
Pump fed application
When you want to use the UltraSieve above the water level
with a submersible pump from the pond you must connect the
pump hose to the 110mm inlet. The tank connector will then
be used as the return flow to the pond. When this tank
connector is too small in case of the pump speed you need to
enlarge this connector.
In case the floating device is reducing the incoming water too
much because the adjustable dam is floating too high you
can remove the floating device completely. In this case you
will always have the maximum capacity.
Filling the floating device
Fill the unit with 3 litres of water for counter weight and put
the plug in the hole.

Maintenance
It is advisable to monitor the UltraSieve every day. Maintenance is very easy because of the waste outlet. In
fact maintenance is about two operations:
1. To remove the waste that is on the surface of the sieve (every day).
2. To remove the waste that has gone into the profile wires of the sieve (only when necessary).
1. Removing the waste that is on the surface of the sieve is very easy by opening the waste outlet and to
rinse the waste away with a normal hose pipe. Another method to have water run over the screen is
pushing down the adjustable dam which will flood the screen with water. When the adjustable dam is in
a low position already because of the pump speed you can pull up the dam for a short while and push
it back downwards again.
2. To remove the waste that has gone into the profile wires of the sieve you will need a hose pipe with a
powerful spray nozzle or a high-pressure machine. For this way of cleaning you have to place the sieve
in an upright position or take the sieve out of the unit.
After a certain period of time the sieve can get “fat” and this will make it more difficult for the water to go
through. You can clean the sieve with i.e. alcohol.
Note: when you use the sieve for the very first time the surface of the sieve can also be covered with
a very thin film. Make sure you will clean the sieve very thorough with alcohol before using it.
Removing the sieve
First remove the water “guide” (A) from the unit.
Now you can take out the sieve for maintenance.
Removing the floating device
and the adjustable dam
First remove the floating device completely from
the dam by loosening the stainless (10mm) bolt
(as explained at page 3). To remove the dam you
need to remove the stainless screw (B) from the
unit in order to slide the dam completely out of
the unit. This screw normally prevents the dam
from moving up too high.
