3 Intended Use
The systems of the OmniaTap xs series are used for the direct treatment of drinking water into pure
and ultrapure water for laboratory use. In order to ensure maximum quality of the pure and ultrapure
water with the longest possible service life of the consumables, the OmniaTap xs system must be fed
with drinking water in accordance with DIN 2000. Any other use of the system is not permitted and is
considered improper use.
The pure / ultrapure water produced is used as a solvent or rinsing agent in a wide variety of analysis
methods such as high-performance liquid chromatography (HP C), ion chromatography (IC), atomic
absorption spectrometry (AAS), ultra-trace analysis, etc. It is also used in a variety of chemical and
biochemical applications such as preparing reagents, cultivating cells, etc.
The treated water is not suitable for consumption.
The system must not be used for the production of pharmaceuticals and is not a medical device.

9 Function description
The systems of the OmniaTap xs series prepare drinking water directly into pure and ultrapure water
by using several treatment technologies. The produced ultrapure water meets the respective
requirements of the ASTM, ISO, USP and C SI standards.
For treatment, the feed water is fed into the OmniaTap xs system, which is pumped through the pre-
treatment cartridge with integrated reverse osmosis module by means of a pressure booster pump.
The quality of the appropriately pre-treated water and thus also the condition of the pre-treatment
cartridge are continuously monitored by the first conductivity measurement ( F1). The current values
of the conductivity measurement can be shown on the display of the operating/withdrawal unit
(OptiFill Dispenser) for checking purposes. In the next step, the water is passed through a UV reactor,
where it is disinfected with the help of UV radiation. The water then flows through the ultrapure water
cartridge, which removes the remaining ions, to remove a maximum of non-ionized compounds. The
quality of the ultrapure water and the condition of the consumables are monitored using a
temperature-compensated conductivity measurement ( F2). The conductivity values measured are
shown on the display of the OptiFill dispenser.
The treated water is first pumped into the tank up to the maximum level. To ensure consistently high
quality of the treated water, the water circulates periodically from the tank through the ion exchange
cartridge, and the UV reactor (only with OmniaTap xs UV) back into the tank with the help of the
circulation pump.
Ultrapure water can be dispensed directly from the OmniaTap xs system using the OptiFill dispenser.
In order to obtain maximum water quality, the water is pumped from the tank via the ultrapure water
cartridge, and the UV reactor (only with OmniaTap xs UV) to the OptiFill dispenser immediately before
it is withdrawn, with the aid of the circulation pump. As a final treatment stage, the ultrapure water
runs through a sterile filter attached to the OptiFill dispenser.
With an optionally available pump station, an external consumer can be supplied directly with pure
water from the tank.

10 Assembly
10.1 Operating environment
When selecting the installation location, observe the following requirements:
- The pressure of the feed water must be between 0.5 and 6 bar.
- The standing surface must be level.
- A suitable protective contact socket must be available for the electrical supply of the OmniaTap xs
system (see technical data).
- There must be sufficient free workspace for problem-free operation, maintenance and repairs.
- There must be sufficient space to operate the system.
- An on-site, lockable feed water connection with R¾" external thread is required.
The system is only intended for operation within an industrial environment. In other
environments, electromagnetic immunity cannot be guaranteed.
Temperatures below +2°C can damage the device due to frost!
The feed water pressure must be less than 6 bar, otherwise the system can be damaged!
If necessary, use a pressure reducer.
Make sure a free drain is available to avoid water damage!
A free outlet, primarily a funnel siphon DN 50, is to be provided for the rinsing water of
the OmniaTap xs system in the immediate vicinity of the location. The upper edge of the
outlet must not exceed a height of 300 mm above the level of the appliance in order to
ensure free outlet and thus flawless functionality of the drain. It must be ensured that the
flushing water line is neither closed nor throttled.
A DN 50 floor drain with free drainage is to be provided in the operating room. If there is
no floor drain, we recommend using a water monitor to prevent damage to the system
and equipment as well as the building.
10.2 Assembly
Set up the OmniaTap xs system at the operating site and make sure that the system is
standing securely. When transporting the system, never lift it by the dispenser arm, only
by the rear wall, bottom or side walls of the main body. See chapter "Transport and
packaging".
In order to protect the power pack from moisture, it must not be operated lying on the
table next to the device. Attach the power pack to a suitable wall near the device using
the bracket included in the scope of delivery.

Water can escape through leaks. Therefore, always make sure that the floor in the area
of the work surface is dry to avoid accidents caused by slipping.
Use the connection accessories to connect the OmniaTap xs system to the feed water connection and
to the free drain. Observe the requirements for the feed water (see technical data). Connect the
connection hose with integrated hat filter with its R3/4" internal thread to the house feed water
connection. Now plug the free end of the 8mm hose into the 8mm quick connector labelled "Inlet" on
the back of the system (see System Connections). Then connect the second 8mm hose to the "Drain"
device connection and guide the free end of the hose into a drain, through which the rinsing water can
drain without pressure. Connect the sterile tank overflow with an 8mm hose to the free drain as well.
Screw the sterile ventilation filter into the thread provided on the back, top left of the tank.
Finally, open the shut-off valve on the building's feed water connection. Check the hose connections
for leaks.
Remove the cover of the OmniaTap xs system and place the pretreatment cartridge in the right slot
and the ultrapure water cartridge in the left slot. Connect the cartridges with the quick-release
couplings by pushing them on. The quick-release fasteners must audibly click into place.
