NOTE
Make sure that the frame is clean for the mounting. If solid parti-
cles such as sand grains are between the frame and filter plate,
the membrane could be damaged when the frame parts are
screwed together.
Disassembly To disassemble the frame and filter plate, proceed in reverse order of
installation.
4 Installing the filter module
Bild 4-1 Filtration unit (filter module mounted on the guide slide)
1Fix the filter module to the height adjustable guide slide (scope of
delivery: suction tube) with the aid of 2 Allen screws (Allen
wrench size 4). The tube connections must point downward.
2Connect the blue sample tube to the quick coupling of the adapter
of the filter plate. The adapter (see pos. 2 in Bild 3-1) is freely
rotatable.
3Submerse the filtration unit in the basin or channel.
The frame only serves as a bracket, not as a seal. The fil-
ter plate is tight itself.
The blue sample tube must be clean, especially where it
should be connected.
Dirt particles in the sample flow can, for example, block the
valves.

5 Maintenance / cleaning
5.1 Cleaning the filter plate
When to clean the filter plate can be determined empirically based on
the negative pressure display on the filtration pump.
With a delivery height of approx. 2 m and a new filter plate, the neg-
ative pressure is approx. -0.3 bar.
Every meter of delivery height increases the negative pressure by

FM/PC, FM-Case/PC, Filter/PC Maintenance / cleaning
9
ba76171e02 04/2019
approx. -0.1 bar.
If the negative pressure increases by a further -0.3 ... -0.4 bar with
time, the filter plate is covered with solid matter from the sample and
has to be cleaned.
When the contamination of the filter plate grows, the negative pres-
sure in the non-active condition of the filtration pump increases.
If there is still negative pressure after cleaning, the suction line may
possibly be blocked.
Prior to starting the cleaning process, switch off the filtration pump (with
the Stop key, or switch off the analyzer completely).
NOTE
The filter plate is easily damaged.
Never touch the filter plate with sharp-edged objects or place any
objects on it.
Pressure on the filter plate must only be applied from the outside.
No counter pressure may build up through the suction line.
The filter plate can be cleaned either mechanically or chemically.
Maintenance interval 2 to 8 weeks, depending on the application
5.2 Mechanical cleaning
Preparations 1 Put the analyzer in the safe state suitable for maintenance and
repair work.
The steps required are listed in the operating manual of the ana-
lyzer (chapter Maintenance).
2Switch off the filtration pump with the Stop key.
3Pull the filtration unit out of the basin or channel.
•The filter module does not have to be separated from the
guide slide!
The mechanical or chemical cleaning of the filter plate may
take some time. We recommend: Use a replacement filter
module (FM/PC) during the cleaning process to keep the
downtime of the analyzer as short as possible.
Prior to removing or plugging in the sample tube, clean it
with clear water and a cloth, for example. Dirt particles in
the sample flow can, for example, block the valves.

Maintenance / cleaning FM/PC, FM-Case/PC, Filter/PC

•Do not dismantle the filter plate (Filter/PC) from the frame (FM-
Case/PC).
4Rinse off any coarse contamination with low water pressure (e.g.
with a watering can or wash bottle).
5Then carefully remove the coating from the filter plate using the
soft special brush (scope of delivery FM-Case/PC). Normally it is
easy to see the brownish coating coming off while the lighter sur-
face of the filter plate appears.
NOTE
Do not press the special brush too firmly on the surface of the
filter plate and do not change the moving direction of the brush
(do not scrub).
6After cleaning, check both sides of the filter plate for damage.
7Thoroughly clean the special brush under running water, dry it
and store in a dust free place until the next use.
8Submerse the cleaned filtration unit in the basin or channel.
9Switch on the filtration pump with the Start key.
Restarting the
measuring operation
Carry out the general steps to restore the readiness to measure at the
analyzer (see operating manual of your analyzer, chapter Mainte-
nance).
5.3 Chemical cleaning
Chemical cleaning is recommended if mechanical cleaning no longer
achieves any significant improvement, i.e. the negative pressure on the
manometer no longer decreases significantly after mechanical clean-
ing.
In this case, the filter plate is blocked. The blockage is mostly organic
and can only be removed by chemical cleaning.
The chemical cleaning is carried out with the aid of a suitable container
(Filter-CL) for the cleaning bath. The amount of cleaning solution
required depends on the shape and size of the cleaning container.
Cleaning solution In most cases, organic blockages can easily be removed with an aque-
ous sodium hypochlorite solution (chlorine bleaching agent, NaClO,
1 % active chlorine). In some cases, NaOH 4 % (sodium hydroxide) has
proven effective.

FM/PC, FM-Case/PC, Filter/PC Maintenance / cleaning

ba76171e02 04/2019
In the event of calcification, diluted hydrochloric acid (HCl) is recom-
mended (0.01 mol/l HCl, 0.036%, pH 2).
Preparing the cleaning
solution
The cleaning solution for the filter plate can be made from different
detergent concentrates by diluting with water. Prepare the cleaning
solution according to the following table. It can be mixed in the cleaning
container.
Pre-cleaning Prior to each chemical cleaning, pre-clean the membrane with the spe-
cial brush and rinse it with water. See section 5.2 MECHANICAL CLEAN-
ING.
Chemical cleaning 1 Dismount the filter module from the guide slide.
2Complete submerse the filter module (filter plate in the frame) in
the cleaning container with the cleaning solution for the filter
plate.
3Start with a reaction time of 30 minutes.

nance).
5.4 Exchanging the filter plate
NOTE
The filter plate is easily damaged.
Never touch the filter plate with sharp-edged objects or place any
objects on it.
Maintenance interval As necessary, if cleaning does not achieve any improvement.
Proceed as follows when you want to exchange the filter plate:
Preparations 1 Put the analyzer in a safe state suitable for maintenance and
repair work.
The steps required are listed in the operating manual of the ana-
lyzer (chapter Maintenance).
2Switch off the filtration pump with the Stop key.
3Remove the filtration unit from the medium.
Even filter plates that are supposedly irreversibly blocked
may be restored by leaving them in the cleaning solution for
a longer period of time and then rinsing them several times.

10 Submerse the filtration unit in the basin or channel.
11 Switch on the filtration pump with the Start key.
Restarting the
measuring operation
Carry out the general steps to restore the readiness to measure of the
analyzer (see operating manual of your analyzer, chapter Mainte-
nance).
5.5 Storing a used filter plate
Proceed as follows when you want to store the filter plate:
1Clean the filter plate mechanically.
2Clean the filter plate chemically.
3Rinse the filter plate under running tap water.
4Protect the filter plate against drying out by storing it in the Filter-
CL cleaning container or in a closed plastic bag.
NOTE
Protect the filter plate from drying out. If the filter plate dries out,
it becomes hydrophobic, blocked and no more sample solution
can go through.
Actions if the filter plate
has dried out
If the filter plate has dried out anyway, proceed as follows:
Submerse the filter plate in a 30 % ethanol or spirit solution for about
60 seconds (approx. 5 l solution are required for the filter plate to be
completely submersed in the Filter-CL cleaning container).
This reduces the surface tension of the filter plate, and the flow rate
should come up to the usual value. For fault-free operation, the filter

plate must not dry out again, otherwise the procedure has to be repeat-
ed.
