1. Drill four holes with a diameter of 12 mm (0.47 inch) into the side of the wall facing the basin.
The distance from the upper end of the wall should be approx. 10 cm (3.94 inch).
2. Screw the holders in.
Make sure, the basin holder is at least 60 cm (23.6 inch) below the water level (resp. the open
channel holder at least 35 cm (13.8 inch)).
3.3.2 Mounting the retaining slide and filtrate pipe
Perform the following steps outside the basin resp. the open channel:
1. Feed the filtrate hose (→å6, pos. 3) of the filtrate line (pos. 1) through the T-piece at the
PVC retaining slide (pos. 5).
2. Screw the filtrate line in tight with the PVC hose gland of the T-piece.
3. Fasten the stainless steel chain at the retaining slide by directing it through the heaxagon nut
(pos. 8).
4. Remove the PVC screw caps (pos. 4) and place them so that they can be reached.
"Caution!
• Secure the retaining slide, the stainless steel chain, the filtrate line and the PVC caps, in order to
prevent them falling into the basin.
• Do not push the retaining slide onto the mounting guide pipe before having mounted the filter
elements.

3.3.3 Mounting the filter elements
The filter elements are delivered ready for use. They are packed in a plastic bag with an additional
cover of corrugated cardboard to protect them against mechanical damage.
"Caution!
• The surface of the filter element membrane (bright surface) must not be touched or in any way
scratched with sharp objects or fingernails. Otherwise, the membrane is irreparably damaged.
Therefore, always handle the filter element at the free-standing PVC ends.
• Once it is used for the first time in the basin, always keep the membrane moist. Otherwise, it
becomes brittle and breaks.
!Note!
You will need an open-end wrench 14/15 a/f.
Installation:
1. Open the corrugated cardboard cover at the top by removing the tear-off strip.
2. Remove the corrugated cardboard spacer. There is a threaded elbow joint in the middle of it,
which you will require in the step after the next.
3. Take out the filter element and remove the plastic bag.
4. Screw the threaded elbow joint into the threaded hole on the reverse side of the filter element.
Carefully tighten the threaded elbow joint with the open-end wrench, so that the O-ring on
the threaded elbow joint seals cleanly to the PVC carrier plate. Avoid over-tightening the
thread.
5. Have the PVC screw caps (→å6, item 4) ready.
6. Put the filter plate onto both threaded adapters at the retaining slide (item 5) such that the
threaded elbow joint faces the retaining slide.
7. Screw the PVC cap on by hand.
8. Cut the filtrate hose (item 3) to the right length, so that it runs in the bend.
!Note!
When using numerous filter elements, ensure that the colored identification sleeves on the filtrate
hoses do not fall off and are not cut off. Used hoses should be shortened by approx. 10 mm (0.39
inch) because the lateral surface always gets scratched somewhat when pulled out. This leads to
leakages.
9. Slide the filtrate hose into the threaded elbow joint coupling and press it all the way in. There
is an O-ring in the coupling, so that the hose has to be pressed in until a pressure point has
been overcome.
10. Push the retaining slide with the filter element onto the mounting guide pipe.
11. Put the retaining slide with the filter element down by the chain until the limit stop. Secure
the chain end at the rail.
The complete filter unit has to be below the water level.

3.3.4 Mounting the control box
a0007160
Fig. 8: Control box dimensions, left front view, right side view
Depending on the version, the control box is delivered with two clips for rail mounting or with four
plastic brackets for wall mounting.
1. Mount the clips or the brackets at the holes intended for that purpose on the reverse side of
the control box. For this, the clips must be fixed to the upper holes.
2. Rail mounting:
Screw the clips on the highest, horizontally-running rail pipe, right by the filter station. For the
box to hang straight, the supplied rubber buffer must be attached to the reverse side of the box.
For this, drill a hole with a 4 mm (0.16 inch) diameter in the middle of the box position, on
which a lower horizontal rail pipe is situated. To secure the rubber buffer, use the supplied
Phillips screw.
3. Wall mounting:
Hold the box with the brackets screwed onto it against the wall and mark the holes. Then drill
the holes and use 8 mm screws and fitting anchors or 8 mm anchor pins to secure the box to
the wall.

"Caution!
Lay hose lines such that they are protected against frost, where possible in underground cable ducts.
Make sure that you do not overstretch the hose.
Electric band heater up to 20 m (66 ft) and more (connection in the control box):
If the hoses and the electric band heater have not already been connected in the factory, proceed as
follows:
1. Remove the plug from the thermal switch's feeder cable with an edge-cutter.
2. Loosen the nut on the Pg hose gland from the end of the spiral hose.
3. Pull the thin filtrate hose first and then the thermal switch incl. its feeder cable through the nut.
4. Guide all hose ends and the thermal switch through the hole (→å11, pos. 10) into the
control box.
5. Insert the hose gland into the hole and screw the nut on tight.
6. Remove the foamed plastic pad from the pipe socket. Slide the thermal switch into the pipe
socket, such that the end of the electric band heater is at the top and the feeder cable is at the
bottom (→å12).
7. Push the foamed plastic pad over the thermal switch into the pipe socket.

5.1 Operation and commissioning
The following chapters provide you with information on the sample preparation unit's operating
elements and explain how to make settings.
In Chap. 6, “Commissioning”, you will find the procedure for initial start-up and for daily operation.
5.2 Display and operating elements
Main switch
Timer
The timer is a time relay of "Trumeter 7955 X" type. When CAT430 is delivered, the timer is ready
to use installed and connected.
Please refer to the following figure for information only.
5.3 Local operation
5.3.1 Cycle times
For reliable operation and achievement of long rinsing intervals, sufficient pause times between the
pumping times are necessary.
The pause times depend on the number of filter elements and on the pumping parameters for supply
output and speed.
The factory-set values for pumping (On) and pause times (Off), as well as the fluid quantities per
pumping cycle are displayed in the following table.

!Note!
In principle, you can make other settings for the cycle times.
Extending the pump time with constant pause times tends to result in shorter rinse intervals. You
should check whether this is acceptable for your application.
5.3.2 Pump capacity
5.3.3 Timer setting
During operation of the CAT 430, the "Trumeter 7955 X" display shows the respective operating
status (relay symbol on = pumping, off = pause) and the remaining time until switching over to the
next operating status.
During programming, the current settings for pumping and pause are displayed.
1. Hold down the "PROG" key until the countdown (3-2-1-0) is completed and
"RC" (without any additional symbols, i.e. not "RC=" or something else) appears
in the display.
If "RC" does not appear after the countdown, keep pressing "PROG" until "RC"
appears.
2. Press "RESET".
3. "0 SEC" (SEC under the number) appears on the right of the display.
4. Press "RESET" again.
5. A three-digit value for seconds now appears in the display. The last figure flashes.
Here, you can configure the Operating time of the pump.
6. Pressing "PROG" increases the flashing figure one at a time, with "RESET" you
can switch to setting the next figure.
7. Set the desired value for the pumping time.
8. After setting the value for the third figure, press "RESET" again.
The setting for another three-digit value appears. Here, you can set the Pause time.
9. Proceed exactly as with the pumping time configuration.
