B Basic information
1 | Laws, regulations, standards
In the interest of good health, rules cannot be ignored when it
comes to the processing of pool water. This operation manual
takes into consideration the current regulations and stipulates in-
formation that you will need for the safe operation of your water
treatment system.
Among other things, the regulations stipulate that
•only approved specialist companies are permitted to make
major modifications to the water supply facility.
•That all contact parts are regularly maintained and preven-
tively serviced.
•That the operation manual and the maintenance schedule of
the system manufacturer are complied with.
The DIN standard 19643, the Ordinance on Pool Water, stipu-
lates the requirements regarding the pool water quality. The con-
centrations of the disinfectants dosed as well as the resulting by-
products are also indicated therein.
Note: The disinfection system GENO-GENO-UV-75 is designed
for the disinfection of pool water and must not be operated in the
drinking water sector. They are installed downstream of water
treatment systems.
2 | Disinfecting impact of UV light
UV light (ultraviolet) is light with a wavelength between 100 and
380 nm. These wavelengths are below the sensitivity limit (in the
invisible range) of the human eye.
For UV disinfection, the wavelength at
254 nm is of particular significance. This wavelength is emitted
by low-pressure mercury lamps, which are designed similarly to
normal fluorescent lamps.
The disinfecting properties of UV light are due to the fact that
light of a wave length of 254 nm is absorbed by the nucleic acids
in the genetic material of micro-organisms. The absorption of the
high-energy radiation results in the modification of the genetic
material (DNA resp. RNA) and leads to an incapability to repro-
duce.
The intensity of the room irradiation (light dose) required to inac-
tivate micro-organisms depends on the respective species and
population. Fungi, spores and algae require a much higher room
irradiation than bacteria and viruses.
In the technical regulation W 294 of the DVGW (German Associ-
ation of the Gas and Water Industry), the minimum room irradia-
tion was specified as 400 J/m². At this room irradiation, a reduc-
tion rate of 99.99 % for viruses and bacteria is achieved.
For further and more detailed information, please refer to DVGW
worksheet W 294-1.

3 | Room irradiation
The level of room irradiation depends on the irradiation intensity
and the duration of irradiation. The irradiation intensity depends,
in turn, on the specific absorption coefficient of the water at 254
nm (SSK254). The organic substances (e.g. humic acids) and in-
organic salts (e.g. ions of iron, manganese) in the water are of
particular importance for UV disinfection, as they absorb the UV
light at 254 nm and thus reduce the light transmission. Since the
wavelength of 254 nm is in the invisible range, the SSK254 can
only be determined using a UV-VIS spectrometer and not with
the naked eye.
Furthermore, the irradiation intensity depends on the age of the
UV lamps. The output of the UV lamps decreases with increas-
ing operating time. In order to be able to continue to guarantee
the required room irradiation, the lamp must therefore be re-
placed at the end of its service life.
The irradiation duration results from the flow rate and the volume
of the GENO-UV-75 disinfection unit.

3 | Intended use
The GENO-UV-75 UV disinfection unit is designed for the disin-
fection of pool water and must not be operated for drinking wa-
ter.
The GENO-UV-75 disinfection unit is installed downstream from
the filter system and upstream from the pH value correction and
the disinfectant dosing.
The GENO-UV-75 disinfection unit is matched to the water de-
mand and water quality expected during installation. The speci-
fied flow rate must be observed.
The prerequisite for the safe disinfection of the water is that it be
largely free of turbidity and only suffers minor microbiological
contamination. Water containing turbidities or a permanently low
or short-time peak load of germs indicating faeces requires a
treatment to separate particles.
The systems may only be operated if all components are in-
stalled properly. Safety equipment must NEVER be removed,
bridged or otherwise tampered with or disabled.
The designated application also includes the information con-
tained in this operation manual and all safety regulations that ap-
ply at the installation site being complied with, and the mainte-
nance and inspection intervals being observed.
The GENO-UV-75 disinfection unit is designed exclusively for
use in industrial and commercial fields.

E Start-up
The work described here should resp. may only be carried out
by Grünbeck's technical service/authorised service company or
by specialised trained personnel.
1 | Mounting the protective quartz pipe
Caution! When mounting the protective quartz pipe, ensure that
it (pos. 2) is inserted into the protective quartz pipe guide inside
the stainless steel container. Use the enclosed assembly aid for
mounting.
Note: To facilitate mounting, a little sealing paste can be applied
inside the seal. This also facilitates disassembly in the event of
maintenance or spare parts.
Caution! Care must be taken that no sealing paste is applied in
the area of the protective quartz pipe through which the light
generated by the UV lamp passes.
Note: Do not overtighten nuts to avoid damaging the quartz
glass. Due to the tolerance of the components, sealing the UV
unit may be achieved without the stainless steel binder ring (pos.
3) touching the stainless steel container (pos. 1).
