2.2 Safety advice
DANGER!
Danger due to electrical current
An electric shock can lead to burns and serious injury and
even death.
nWork on the electrics may only be carried out by
trained electricians.
nSwitch off the mains voltage before opening the
casing.
nSwitch off the mains voltage before connecting the
mains plug.
WARNING!
Risk of scalding from automatic regulation
By way of pre-set parameters, the control can independ‐
ently control flushings and set the temperature of the
flushing water.
If a thermal disinfection process is initiated centrally, the
system cannot check whether persons are at risk from
this process who may be in the vicinity of a fitting.
nEnsure that there are no persons in the danger zone
when a flushing / thermal disinfection is carried out.

WARNING!
Danger in case of unauthorized third-party
access to the computer network
It cannot be excluded that third parties who can get into
the computer network also gain unauthorized access to
the browser-based software for controlling the flushing
station.
nProtect your user name and password from third-party
access.
nA possible break through this access protection
cannot be fully excluded. For this reason, change your
password regularly.
Technical progress
The flushing station has been development pursuant to
state-of-the-art computer and network technology.
It cannot be excluded that the flushing station will not be
compatible with any future computer and network sys‐
tems.
nPossibly, the flushing station may require technical ret‐
rofitting.
Data protection
The user behaviour of a certain fitting can possibly be
allocated to one individual user. The data collected in this
way is personal data.
nInform the user of the flushing station that data is col‐
lected.
nThe user must give his or her consent.
Data protection
It is possible to access the system externally using mobile
end devices. As operator of the flushing station, you are
obliged to check whether the utilization is legally per‐
mitted, in particular if the collected and saved data is sub‐
ject to professional or specific official secrecy.
nEnsure that personal data is processed and used only
in compliance with the applicable data protection reg‐
ulations.

2.3 Intended use
2.3.1 Areas of use
The flushing station is intended for use in potable water installations. It
supports the operator in upholding potable water quality and can be
installed in ring or series pipelines.
The flushing station can be controlled directly via the display or the
Internet application. For control via the Internet application, the end
devices can be connected to the flushing station by means of a WIFI or
Ethernet connection. The flushing station can be connected to a higher-
level control system for building automation (BA). To this end, connec‐
tion options via Ethernet and binary BMS module are available.
2.3.2 Maintenance
Regular maintenance is part of running the system properly, see
Ä Chapter 3.7.3 „Perform maintenance“ on page 75.
Inform the building owner or the operator of the potable
water installation of their inspection and maintenance obli‐
gations.

2.4.2 Operating mode
By providing for controlled water exchange, the flushing station helps to
ensure that drinking water systems are used as intended.
Flushing can be carried out as follows:
Start function:
npursuant to interval (factory setting)
npursuant to time
Flush actuation
Product information
Flushing station with Viega Hygiene+ technology 11

npursuant to use
npursuant to temperature
Stop function:
non reaching the flush volume (factory setting)
nat constant temperature
nWhen target temperature is reached
The flushing station can be used with or without multi-functional sensor.
Without the multi-functional sensor, flushing is carried out time con‐
trolled pursuant to interval or time.
With a multi-functional sensor, the water temperature and the usage
behaviour can be taken into consideration as well. If equipped with
sensor, the system checks for insufficient use or impermissible temper‐
ature change at the specified point in time. This would indicate insuffi‐
cient water exchange or stagnation in the pipeline. In this case, the
system will trigger flushing pursuant to the set parameters at the speci‐
fied points in time.
A flow limiter is located under the sieve insert in the inlet side of the
magnet valve. The flow limiter limits the flushing water volume to
0.07 l/s (4.2 l/min). This provides for water exchange with the lowest
possible flow noise.
The flow limiter must not be removed.
A backflow sensor is located in the odour trap. It monitors the water
level in the odour trap base unit. In case of backflow, it stops an
ongoing flushing and ensures that no further flushing is triggered.
A flow sensor is used to accurately determine the flush volume during
the flushing process. The flow sensor is mounted below the magnet
valve at the wastewater side.
A free discharge pursuant to applicable regulations and a backflow
sensor are integrated in the odour trap, see Ä „Regulations from sec‐
tion: Functionality“ on page 6.

system with acoustic insulation.

mounted in Viega pre-wall systems, in traditional dry construction, and
in solid construction, see Ä „Regulations from section: Sound protec‐
tion“ on page 6.

3 Handling
3.1 Transport and storage
Observe the following with transport and storage:
nAvoid heavy blows and vibrations.
nStore components in a clean and dry place.
nDo not remove the components from the packaging until immedi‐
ately before use.
3.2 Assembly information
3.2.1 Mounting conditions
Mounting the device is permissible only if the following conditions are
met:
nThe device must be mounted in potable water installations only.
nIn series pipelines, the flushing station must be arranged as the last
consumer.
nIn ring and series pipelines for hot potable water (PWH), comply with
the output times pursuant to the applicable regulations, see Ä „Reg‐
ulations from section: Mounting conditions“ on page 6.
nAccess to the flushing station must be possible for maintenance and
repair. All components of the flushing station must be easily acces‐
sible.
nInstallation below the backflow level is only permissible if the water is
drained by means of a wastewater pump station.
nOnly use DVGW approved sealants in accordance with the appli‐
cable regulations, see Ä „Regulations from section: Mounting condi‐
tions“ on page 6.
Handling
Flushing station with Viega Hygiene+ technology 17

3.2.2 Potential equalisation
DANGER!
Danger due to electrical current
An electric shock can lead to burns and serious injury and
even death.
Because all metallic piping systems conduct electricity,
unintentional contact with a live part can lead to the whole
piping system and components connected to it (e. g. radi‐
ators) becoming energised.
nOnly allow electrical work to be carried out by qualified
electricians.
nAlways integrate the metal piping system into the
potential equalisation.
The flushing station must not be integrated as a separate component.
It is the fitter of the electrical system who is responsible
for ensuring that the potential equalisation is tested and
secured.

3.2.4 Required accessories
For commissioning and configuring the flushing station, you will need:
nEither laptop computer, smartphone or tablet computer (note the
system requirements, see Ä Chapter 2.4.4 „Technical data“
on page 13).
Operating the control only via display is possible as well.
3.3 Assembly
3.3.1 Mounting the base
The flushing station is delivered pre-assembled and ready for connec‐
tion. All components are mounted to the base and have been tested for
leak tightness and proper function.
The flushing station is delivered packaged in a cardboard box. This box
is later used for site protection (also see Ä Chapter 3.3.9 „Notes on wall
construction“ on page 35).
Take care not to damage the cardboard box, it will be
required later.
▶Do not remove the cardboard box until you are ready to mount the
device.
▶Put the cardboard box in a dry and clean space for interim storage.
To give you a better view, an empty base is shown for the
following assembly steps.
Use Steptec slot nuts model 8437.90 for assembly.
