The installation instructions must not be copied
or reprinted, either in full or excerpts thereof,
without written authorisation from Dürr Dental.
Although we have taken great care to ensure that
the information contained in this handbook is
correct and accurate, Dürr Dental accepts no lia-

2 Safety
The unit has been developed and designed in
such a way that dangers are effectively ruled out
if used in accordance with the intended use.
Nevertheless, residual risks can remain.
You should therefore observe the following notes.
2.1 General notes
Observe the following notes to ensure safe and
effective operation:
❯Water generated by the Hygowater system is
not suitable for drinking.
❯Comply with the country-specific regulations
and standards for the installation of water treat-
ment systems and for connection to the treat-
ment unit.
❯Do not use the Hygowater system for more
than two dental treatment units unless the cor-
responding accessories have been installed.
The system's internal filter may get blocked
and the system may put a stop to operation.
❯The water system described in the following
should be kept short and straight. Piping with
blind ends and long pipes make the Hygowater
system less effective. The water can be con-
taminated again by a flow system with an
unfavourable design.
❯Make sure the filters (pre-filters/ultrafilters) are
serviced or replaced as required. The internal
filters need to be clean if the Hygowater sys-
tem is to work effectively. Hard water reduces
the efficiency of the disinfection process or
brings it to a standstill. The filters may become
blocked and cause damage to the electrolysis
chamber.
❯The recommended water pressure may not be
exceeded. The potential consequences of the
pressure exceeding 6 bars as stipulated are
burst pipes and flooding.
❯Verify that the effect is as it should be at regular
intervals. The chlorine content in the water from
the transmission instruments or cup filler must
be measured every week to ensure effective
operation. The chlorine content may fluctuate.
Important information
8500200015L02 1910V001 3
EN

❯Do not use the Hygowater system with liquids
other than water or without filters. The unit is
designed to be used to disinfect processed
water in the dental treatment unit, with the
quality equivalent to that of drinking water.
Using the unit with liquids other than water
and/or without the correct filters will damage
the unit and make it less effective.
❯The unit must always be kept perfectly upright.
Do not try to operate the unit when it is on its
side or tilted, as water will leak out and poten-
tially cause damage to the unit or its surround-
ings.
❯The use of oxidative disinfectants, such as free
chlorine, represents a potential source of corro-
sion. The Hygowater system works with a low
[...]. Make sure that your dental treatment unit
is suitable for use with processed water of
drinking water quality in line with the WHO
Guidelines for Drinking-Water Quality and the
limits set out by the EU.
❯Use water from the Hygowater with caution.
Always read the label and product information
before use.
2.2 Intended use
The unit generates active chlorine* for disinfec-
tion of water pipes for dental treatment units.
Spectrum of activity: reduces water bacteria –
including legionella bacteria.
*Active chlorine is formed through electrolysis
from (sodium) chloride and is the designation
used by the EU in the Biocidal Products Regu-
lation.
2.3 Improper use
Any use of this appliance / these appliances
above and beyond that described in the Installa-
tion and Operating Instructions is deemed to be
incorrect usage. The manufacturer cannot be
held liable for any damage resulting from incor-
rect usage. The operator will be held liable and
bears all risks.
❯Do not use the Hygowater system on dental
treatment units when other disinfection sys-
tems are switched on. This may stop the
Hygowater from working as effectively or at all.
WARNING
Risk of explosion due to ignition of
combustible materials
❯Do not operate the unit in any rooms in
which inflammable mixtures may be
present, e.g. in operating theatres.
2.4 Systems, connection with
other devices
Additional devices connected with medical elec-
trical devices must be proven to conform with
their corresponding IEC or ISO standards. All
configurations must continue to comply with the
standard requirements for medical systems (see
IEC 60601-1).
Whoever connects additional devices to medical
electrical devices automatically becomes the sys-
tem configurator and is responsible for ensuring
that the system corresponds with the standard
requirements for systems. Local laws take priority
over the requirements outlined above.
2.5 General safety information
NOTICE
Danger to components due to electro-
static discharge (ESD)
❯Establish equipotential bonding
between the person carrying out the
work and the surroundings, e.g. via a
wrist strap that is connected to the
basic unit. Here, the basic unit must be
earthed via the earth terminal.
❯Always comply with the specifications of all
guidelines, laws, and other rules and regula-
tions applicable at the site of operation for the
operation of this unit.
❯Check the function and condition of the unit
prior to every use.
❯Do not convert or modify the unit.
❯Comply with the specifications of the Installa-
tion and Operating Instructions.
❯The Installation and Operating Instructions
must be accessible to all operators of the unit

The Hygowater water disinfection system is a
medical device that must be installed and ser-
viced by authorised personnel to ensure correct
operation.
–Pre-filter – A 100 μm filter captures all particles
above this size.
– Softening – An ion exchanger removes
limescale from the system.
– Activated carbon filter – Removes old chlorine
and odours from the water flowing in.
– Fine filter – A 1 μm filter removes smaller parti-
cles.
– Chlorination – Inline electrolysis generates an
adjustable amount of chlorine, which disinfects
the water.
–Ultrafilter – A special function that captures
microbiological burdens. The retention and
associated long exposure time to free chlorine
ensure that these microorganisms are deacti-
vated by free chlorine even when dosage lev-
els are low. As a result, a stronger barrier is
formed preventing living microorganisms from
penetrating into the water pipes of the dental
treatment unit.
– The lightly chlorinated water that comes out
from the Hygowater or Hygowater Compact
prevents growth of bacteria in the water pipe
of the dental treatment unit and thus also pro-
tects patient health.
Always proceed with caution when using
water from the Hygowater or Hygowater
Compact. Always read the label and
product information before use.
The ultrafilter in the Hygowater or
Hygowater Compact is replaced when
the Customer Service department per-
forms the annual service.
