3.4.1 Mounting the filter element holders
!
Note!
You will need a hammer drill with a 12 mm drill bit.
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 (23.62 inch) below the water level
(resp. the open channel holder at least 35 cm (13.78 inch)).
3.4.2 Mounting the retaining slide and filtrate line
Perform the following steps outside the basin resp. the open channel:
1. Feed the filtrate hose (Fig. 9, 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.

3.4.3 Mounting the filter elements
The filter elements are delivered ready for use. They are heat-sealed in plastic
packaging. The packaging is filled with a preservative solution. The packaging is also
protected against mechanical damage through press boards.
"
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.
•Always keep the membrane moist. Otherwise, it becomes brittle and breaks.
!
Note!
You will need an open-end wrench 14/15 a/f.
To mount the filter elements, proceed as follows:
1. Cut the adhesive strips on the packaging with a knife. Remove the press board.
2. Cut the upper end of the bag open and take the filter element out.
3. Remove the protective nonwoven from the filter plate.
4. Screw the supplied 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 ready.
6. Put the filter plate onto both threaded adapters at the retaining slide such that the
threaded elbow joint faces the retaining slide.
7. Screw the PVC cap on by hand.
8. Cut the filtrate hose to the right length, so that it runs in the bend.
!
Note!
When using numerous filter elements, ensure that the coloured identification sleeves on
the filtrate hoses do not fall off and are not cut off.
Used tubes should be shortened by approx. 10 mm 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 tube has to be pressed in until a
pressure point has been overcome.
10. Push the retaining slide with the filter element (pos. 5) 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.

Endress+Hauser 13
3.4.4 Mounting the control box
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 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 the supplied anchor pins to secure the box to the wall.
3.4.5 Connecting the filtrate lines to the measuring devices
For the connection of the filtrate lines please refer to the following figures.

Filtrate line to the filter elements
If the filtrate pipe to the filter elements has not already been connected in the factory,
proceed as follows:
1. Slide the filtrate hoses protruding from the filtrate pipe (one to four, depending on
version) and the feed line of the heater cables through the Pg hose gland (Fig. 10,
pos. 8). Slide the spiral hose far enough into the Pg hose gland that it is flush inside
and then tighten the Pg hose gland.
2. Cut the filtrate hoses such that you can insert them comfortably into the Y fitting
plug-in connectors (pos. 10).
Filtrate line to the measuring device
The filtrate line to the measuring devices consists of a spiral jacket hose, a thin filtrate
hose and, depending on scope of order, an electric band heater.
In the spiral jacket hose are:
•PTFE hose 1.5/3 mm / 0.06/0.12 inch (standard)
•PE hose 2/4 mm / 0.08/0.16 inch (reserve).
"
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 and more (connection in the control box):
If the hoses and the electric band heater have not already been connected in the fac-
tory, 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 into the control box.
5. Insert the Pg 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.
7. Push the foamed plastic pad over the thermal switch into the pipe socket.
"
Caution!
There is a micro thermostat for the housing heater in the pipe socket. Be careful when
inserting the thermal switch because there is not much space to work in.

8. Guide the feeder cable for the thermal switch through the cable duct (Fig. 10,
pos. 2) to the connection box (pos. 5). For electrical connection, please read the
chapter “Wiring”.
9. Cut the filtrate hose to the right length.
10. Insert the hose into the fitting on the pressure side (top) of the pump.
11. Now lay the filtrate line from the control box to the measuring devices. Where
possible, use available cable ducts or empty underground pipes. With the
corresponding order, the filtrate hose is protected by the electric band heater over
the entire area exposed to frost.
Electric band heater > 20 m (connection in the measuring device compartment):
Guide the filtrate line (opposite end from the thermal switch) and the electric band
heater from the measuring device compartment to the control box.
1. Guide the thermal switch near to the electrical connection (in the measuring device
compartment) into the open. Insert the thermal switch plug into an earth leakage
breaker protected socket.
2. Lay the filtrate line with the electric band heater to the control box. For this, use
available cable ducts or empty pipes.
3. Slide electric band heater, compressed air hose, filtrate hose and the spiral hose
far enough into the Pg gland that the spiral hose is flush inside.
4. Tighten the Pg gland.
5. Proceed as described above from item 8 for connection of the band heater in the
control box.
"
Caution!
In both cases, do not guide the band heater parallely to the thermal switch! Otherwise
the thermal switch reacts to the temperature of the heater instead of the ambient
temperature and therefore switches off the heater.
3.5 Post-installation check
•After installation, check that all connections are fitted tightly and are leakage resistant.
•Ensure that the hoses cannot be removed without effort.
•Check all hoses for damage.

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 CAT 430 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.
5.3.2 Pump capacity
There are two rotary knobs on the right side of the pump to set the following:
1. Stroke length (large knob, front):
Depending on the number of filter elements, here you set:
– 50% (for one filter element)
– 100% (for two filter elements)
2. Clock pulse frequency (small knob, rear):
Always set 100% here (clockwise to the right limit stop).
!
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.
5.3.3 Timer setting
During operation of the CAT 430, the "Trumeter 7955 X" display shows the respective
operating status (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.
This is how to program the time relay:
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
(pumping time).
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.
10. Pressing "RESET" after setting the third figure, the "LEU" message appears in the
display. The time controller is activated as soon as voltage is supplied to the relay.
11. Keep pressing "RESET" until the relay icon appears in the display
again.
The programming procedure is completed.
12. Now switch the middle switch (controller) on the connection box off and
on again.
The controller starts.
