1 Introduction
Congratulations on the purchase of your Hygopure 90 water treatment system. You are the proud
owner of a high-quality and reliable water treatment system for the production of demineralised
water.
This water treatment system was subject to an intensive quality test. This test checked the system
for its function and for leaks.
Please read the installation and operating instructions carefully before starting with the
installation. Retain this manual for later consultation.
The Hygopure 90 water treatment system acts reliably and in an environmentally-friendly fashion
to remove any bacteria, chlorine, hardness components, nitrates, pesticides, heavy metals,
sediment particles, silicates, viruses etc. and provides effective protection for your steriliser. After
pre-filtering, the tap water is cleaned via return osmosis. In contrast to all other methods of water
filtration, this filter technology removes almost all dissolved and undissolved molecule substances
from the tap water. This is based on a purely mechanical procedure without the release of any
chemicals or substitute materials. After the reverse osmosis procedure, the permeate is
desalinated using an ion exchanger. This produces high-quality demineralised water.
An amazing effect of the reverse osmosis technology is that the membrane predominantly lets
just water molecules pass through; the contaminants which it holds back are washes away from a
part of the water. The deflection of the water prevents contaminants either from entering the
cleaned water or from collecting within the system as with other filter methods. This also prevents
blockage of the membrane. In consequence, reverse osmosis membranes also have a very large
service life given constant output and minimum maintenance over many years.
The Hygopure 90 water treatment system is fitted with an eco module (water-saving technology).
This module consists of a hydraulic pump (permeate pump) and a hydraulic valve (automatic
shut-off valve). The eco module increases system efficiency by up to 70% and maintains this
constant whilst the storage tank is being filled. Operation of the eco module does not require
electricity as the water pressure of the waste water provides the requisite energy. The production
of pure water is indicated by a periodic "clicking" of the eco pump and a quiet whistling of the
hydraulic valve. The intervals and volume of the noise depends on the tap water pressure.

2 Important information prior to installation
2.1 Installation requirements
The technical operating conditions of this water treatment system:
Water pressure:
from 2.4 to 7.0 bar
Water temperature:
from 4.0 °C to 38.0 °C
Hardness range:
All hardness ranges from soft (up to 8.4 °dH) to hard (> 14
°dH)
In general, tap water satisfies these requirements. Should you be uncertain, please makes
inquiries with your local provider.
NOTICE:
(1) The installation and maintenance of this water treatment system may only be
performed by trained and authorised persons.
(2) Do not connect the water treatment system to a hot water connection or behind a
pressureless boiler.
(3) Do not subject the water treatment system to temperatures below 0°C.
(4) If the water pressure exceeds 7.0 bar, a pressure reducer must be installed upstream.
(5) Use only microbiologically faultless water for the operation of the system.
(6) Safety reasons mean that we recommend either installing an aqua-stop valve or only
operating the water treatment system under supervision and turning off the water
supply outside the operating time. This avoids potential water damage.
(7) Comply with all general guidelines, local installations and hygiene regulations.
(8) Do not use any aggressive cleaning agents or disinfectants to clean the water
treatment system (inc. hose connections and hoses) as these could cause damage to
the system and result in water damage. Use only the VEWAMED disinfectant for
exterior and internal disinfection. Comply with the specifications of chapter 4 "Care
and maintenance of the water treatment system“.
2.2 Inspection of the delivery

2.4 Location of the main components
Before starting with the installation of the Hygopure 90 water treatment system, you must decide
upon the optimal placing of the three main components filter system (filter group) storage tank
and water tap. Take into account the suitable connection possibilities for the inflow water and the
waste water.
Location of the filter group
The Hygopure 90 water treatment system is ideal for undertable installation, but can also be set
up directly on the work surface next to the steriliser.
NOTICE:
The Hygopure 90 water treatment system must be placed in an upright position and may
not be placed on its rear, otherwise it is impossible to guarantee the functionality of the
eco module.
Ensure that you have easy access to the filter group when you later need to change the filter
cartridge. When changing the filter cartridge, we recommend that you place the filter group
carefully on a towel.
Placing the storage tank
The storage tank should be maintained in an upright position. It is important that the storage tank
remains easily-accessible.
The white pressure hose included in the scope of delivery permits the installation of the storage
tank with a clearance of up to 1.5 metres from the filter group. In some cases, it is necessary to
place the storage tank further away. In this case, please contact your dealer.
Placing the water tap
A surface on the sink or work surface with a 5 cm diameter is required for the installation of the
water tap. Both practical and aesthetic considerations are important in locating the water tap.
Detailed information pertaining to the installation is provided in chapter 3.1.3 of this manual.
The white pressure hoses included in the scope of delivery permit the installation of the water tap
with a clearance of up to 3.5 metres from the storage tank. Should you require longer pressure
hoses, please consult your dealer. To prevent an overly-large pressure fall on the water tap
resulting from overly-long hose lines, the entire hose length "storage tank to the water tap" should
not exceed 8 metres.

3 Installation and commissioning the water treatment system
3.1 Installing the water treatment system
The main section of the installation now begins. Following all the next steps in a sequential
fashion.
3.1.1 Installing the water connection valve
NOTICE:
We recommend that you secure every water treatment unit with an aqua-stop valve on
safety grounds. Alternatively, either only operate the water treatment system under
supervision and turn off the water supply outside the operating time using a central water
supply switch (e.g. ball cock). This avoids potential water damage.
The standard scope of delivery contains a water connection valve (consisting of a tap connection
with a 3/4" thread, a nonreturn valve and a water shut-off valve). The scope of delivery also
contains a tap connection with 1/2". These tap connections fit all outlet valves (cold water taps)
with 3/4" or 1/2" thread. You can plug the grey plug angle connection (included in the scope of
delivery) into the tap connection to ensure optimal hose installation.
The nonreturn valve prevents flowback into the water supply. The nonreturn valve and the water
shut-off valve are already integrated in the blue water inflow hose and are pre-installed.

Now screw in the fitting water connection valve (tap connection) to the tap hand tight. The water
connection valve (tap connection) can be screwed in somewhat tighter if necessary. Keep the tap
closed.
Technical tips regarding the hose connections:
The Hygopure 90 water treatment system only uses high-quality John Guest hose connections
called "Quick Connect Fittings". When using John Guest connections, you need only connect the
pressure hose to the corresponding fitting and you are finished. This enables quick and simple
installation. The following figures show the function of the John Guest hose connections:
Connecting the hose: slide the hose into the hose connection to its fullest extent until it is tight.
The holding element fixes the hose in the connector. The o-ring creates a permanently leak-free
connection. Pull the connection lightly to check it.
Figure: Connecting the hose
Remove the hose: Check that the system is de-pressurised. Push the holding element into the
hose connection and hold using your fingers. You can now remove the inserted hose with your
other hand.
