A General
1 | Preface
Thank you for choosing a Grünbeck product. Backed by decades of experience
in the area of water treatment, we provide custom-made solutions for all kind of
processes.
Drinking water is classified as food and requires particular care. Therefore, al-
ways ensure the required hygiene in operating and maintaining systems in-
volved in the drinking water ordinance. This also applies to the treatment of wa-
ter for industrial use if repercussions for the drinking water cannot completely be
excluded.
All Grünbeck systems and devices are made of high-quality materials. This en-
sures reliable operation over many years, provided you treat your water treat-
ment system with the required care. This operation manual assists you with
crucial information. Please read the entire operation manual carefully before
installing, operating or servicing the system.
Customer satisfaction is our primary aim, and providing customers with qualified
advice is crucial. If you have any questions concerning this system, possible
extensions or general water and waste water treatment, our field service staff,
as well as the experts at our headquarters in Hoechstaedt, are available to help
you.
Advice and
assis-
tance
For advice and assistance, please contact your local representative (refer to
www.gruenbeck.com). In case of emergency, please get in touch with our ser-
vice hotline at [phone]. We can connect you with the appropriate ex-
pert more quickly if you provide the required system data. To ensure that this
information is to hand at all times, please keep the precise equipment data to
hand (refer to the type plate in chapter C-1).

2.1 Symbols and notes
Important information in this operation manual is emphasised by
symbols. Please pay particular attention to this information to ensure
the hazard-free, safe and efficient handling of the system.
Danger! Failure to adhere to this information will cause serious or
life-threatening injuries, major damage to property or inadmissible
impurities in the drinking water.
Warning! Failure to adhere to this information may cause injuries,
damage to property or contamination of the drinking water.
Caution! Failure to adhere to this information can result in damage
to the system or other objects.

Note: This symbol characterises information and tips that make your

B Basic information

Note: Prior to installation, please check the temperature-controlled
flushing for possible transportation damage.
The control unit must be protected against frost and may not be in-
stalled next to heat sources which radiate a lot of heat. The device
itself is approved for an ambient temperature of max. 40 °C.
Warning: The electrical installation may only be carried out by an au-
thorised electrician in accordance with the regulations of the electrical
utility and the applicable VDE regulations. The client must provide an
AC/DC sensitive ground fault circuit interrupter (trip current 30 mA).
The electrical connection is made via a 230V/50Hz AC power system.
Caution! The electrical power supply to the control unit must be dis-
connected before each installation/removal or intervention in the con-
trol.
Do not disconnect the unit from the mains prior to a holiday!

Note: Like the corresponding GENO-UV disinfection devices, the
temperature-controlled flushing must be connected to a permanently
live socket outlet.
Caution! Danger of burns! During continuous operation, the coil of
the 2/2-way solenoid valve can become very hot.

C Product description
1 | Intended use
The temperature-controlled flushing – time-controlled for GENO-UV
serves for the periodic renewal of water in the GENO-UV disinfection
unit. During longer idle times (e.g. holiday, seasonal operation), the
lamp energy can raise the temperature of the water to above the ad-
missible temperature range. This can be effectively prevented by
means of temperature-controlled flushing that is time-controlled.
The temperature-controlled flushing – time-controlled for GENO-UV is
designed exclusively for use in industrial and commercial applica-
tions.
1.1 Mounting of the temperature-controlled flushing – time-controlled for GENO-UV
Plug the electronic part onto the solenoid valve coil as shown in Fig.
D-1. It must be ensured that the drain tap (no. 7) can be
opened/closed correctly. If necessary, the connector part in the elec-
tronics can be turned by ±90°.

Note: Do not damage the cable connections on the plug or the elec-
tronics!

The hose is led to the drain. There must be a free outflow to the drain.
Depending on the GENO-UV disinfection unit, a different volume of
water must be exchanged. The system volumes are listed in the rele-
vant technical data or an extract can be found in the table below.

The time is set as a percentage. For ex-
ample, a setting of 8 s in the time range
0.5 ... 10 s achieves by changing over to
the time range 0.5 ... 10 h, a value of 8
hours.
Example: In the time range 0.5 ... 10 s,
the percentages correspond to the fol-
lowing times:
17 % ≈1,6 s
34 % ≈3,2 s
51 % ≈4,8 s
68 % ≈6,3 s
85 % ≈7,9 s
