The product is designed for use in the main feeder of a complete indoor drinking water
installation (gatekeeper concept), or a part thereof, with a standard consumption capacity
of up to 20 m³/h/88 GPM. The purpose of the equipment is to provide the downstream
drinking water network with bacteria-free supply water.
The intended use involves the connection of the product by a competent installer as
described in this manual, after which in normal use further contact with the product is not
necessary.
4.2. Product functions
Ultrafiltration
Ultrafiltration is a technology that is used to filter small undissolved particles such as
bacteria from water. Ultrafiltration is a membrane-based technique. The inside of the
membrane acts as a very fine sieve, with a pore size of 0.015 to 0.03 μm. The water is
pushed through these pores by the feed water pressure. The reduction of legionella
bacteria by this technique is 99.9999% (Log 6).
Forward flush
The Central ultrafiltration system is equipped with an automatic forward flush function. At
this stage all trapped bacteria that remain in the membranes are flushed to the drain.
Backflush
In addition to the forward flush, the system is also equipped with an automatic backflush.
Here, the membranes of the left filter are flushed upstream with the permeate water from
the right filter. As a result, all the smallest particles that have settled in the membrane
pores are flushed out of this and discharged to the drain.
Integrity test
The equipment is equipped with a unique automatic integrity test for the filter modules.
The word 'integrity' is another name for ensuring proper functioning and density of the
membranes. The integrity of the membranes can be controlled by air pressure. For this
purpose the 'Air Pressure Test' has been developed, using the fact that the membranes
allow water to pass through, but no air. Every 24 hours, all filter modules are automatically
checked for possible diaphragm breakage by means of air pressure. This guarantees the
Filtration

correct operation of the filter modules. If a diaphragm failure occurs, the defective filter is
automatically put out of operation. The malfunction signal then becomes active.
Malfunction signal
If a fault occurs because the integrity of a filter module cannot be guaranteed, a pulsating
auditory signal will be heard of 85 dB. The red light also flashes on the equipment. The
audible signal can be switched off by means of the touchscreen (see section 10).
The malfunction signal can be connected to an external 24V DC fault indicator.
The fault can also optionally be connected to a building management system by means of a
digital signal.
4.3. Operating principle
The operating principle of the product is ultrafiltration, in which the upstream water
(supply) is separated by a physical barrier from the downstream water (downstream
installation). All parts in water smaller than nominal 0.02 μm remain in the filter. The
bacterial safe water (permeate) is supplied to the drinking water system. The trapped
particles are automatically washed away to the drain.
In the event of a power failure, the drinking water will not be shut down.
4.4. Explanation of the display

5.2. Guidelines
When installing the equipment, the following guidelines must be taken into account:
▪If there is a risk of water hammer from the pipe network, a water hammer damper
must be placed in the pipes to protect the filter membranes.
▪Noise caused by the filter installation should be avoided.
▪The system must be protected against freezing and mechanical damage.
▪Never drop the product or parts of it. This can damage them irreparably.
▪Do not use the product if it is damaged. Always contact your supplier. Never attempt
to repair the product yourself.
▪The filter is designed for the purpose of removing bacteria from the tap water and
may only be used for this purpose.
▪Avoid dehydration of the membranes: if the membranes are stored for a longer
period of time, the fibers will dry out, which can result in permanent damage.
▪Avoid direct exposure to sunlight and UV radiation.
▪Protect from abrasive materials. The abrasive material in water can cause permanent
membrane damage. Place a 100 micron pre-filter if visible contamination has been
detected.
▪Avoid abrupt variation in ambient temperature and running water: a thermal shock
should be avoided.
▪Protect against organic solvents and concentrated acids: avoid membrane contact
with polar organic solvents, chlorinated solvents or concentrated acid.
▪Avoid silicone-based lubricants, chemical products and oily liquids: the silicone
materials can cause permanent stagnation of the fine pores of the membrane
element.
▪Transport the product carefully: The membrane elements can be mechanically
damaged if they fall or collide with hard objects.
