2.2 Safety advice
DANGER! Danger due to electrical current
An electric shock can lead to burns and serious injury and even death.
– Work on the electrics may only be carried out by trained
electricians.
– Remove the mains plug before opening the casing.
2.3 Intended use
2.3.1 Areas of use
The Grundfix Plus Control is operated electrically. It is suitable for use in drain pipelines with household-type wastewater carrying faecal matter (up to a temperature of 95 °C with pH values of ≥ 4 or ≤ 10).
The backflow trap is suitable for use in drain pipelines made of HT or sewer pipe DN 100, 125 or 150. When using other pipes such as e. g. clay pipes or cast-iron pipes, the relevant adapters for HT and sewer pipes must be used.
Use in industrial areas or in pipelines, which transport aggressive liquids is not permitted. This includes cleaning agents, which can damage sani­tary equipment, drainage equipment and pipe materials.
Viega recommends closing the emergency trap if operation, where no wastewater is produced, is interrupted for a number of days.

Fig. 2: Correct place of installation of the backflow trap
1 - Street = Backflow level 2 - Area safe from backflow 3 - Connection upper floor 4 - Area at risk of backflow 5 - Protection against backflow through backflow trap
The connection of the upper floor (3) onto the underground pipe must be made between the backflow trap and sewer within the building (5) – only then is it possible to ensure that the wastewater system can func­tion faultlessly. To ensure that drainage is permanently guaranteed, backflow traps may not be employed as the central safeguard for a building with drainage equipment installed above the backflow level (1) – in the event of backflow, it would lead to flooding in the building due to wastewater being unable to drain away (4).
See
Ä „Regulations from section: Place of installation and installation
conditions“ on page 7
Backflow seals and their control units should be installed in such a way that they are always accessible.

The backflow sensor reacts at accumulation heights of 100 mm, measured from the upper edge of the base pipe­line.
Therefore, when planning, the installation heights of the existing floor drains, out of which water could flow in the case of backflow, must be taken into account.
If a backflow trap is retro-fitted in a base pipeline, the height difference of 30 mm between connection pipe and sleeve must be taken into account.
2.3.3 Maintenance
A monthly inspection must be carried out to ensure safe operation. See
Ä Chapter 3.6.1 „Inspection“ on page 33
Maintenance must be carried out twice a year to ensure safe operation. See

2.4.3 Operating mode
The motor-powered flap is open during normal operation. If the pres­sure switch registers the backflow of water, the motor-powered flap is closed, the following display appears
„Back pressure“
and a signal sounds every 10 seconds. The use of the drainage equipment is not possible during this time. A battery emergency power supply ensures the functionality of the system even when the 230 V mains power supply fails.
Using the manual actuator, the backflow trap can be closed manually and independently of the motor-powered flap.

3.2 Assembly
3.2.1 Mount base unit
The installation in the drainage pipeline may only be carried out by con­struction or specialised sanitary companies observing the building regu­lations and following this instruction for use.
Install the base unit horizontally into the base pipeline. Observe flow direction!
At maximum, line up to the middle of the drainpipe. Close emergency shut-off (position "OFF‟). In this way, damage from flooding can be avoided before commis-
sioning.
Lay empty pipe from the base unit to the mounting position of the control unit.
Close the empty pipe at both side using plugs.

3.2.2 Connecting connection cable and pressure hose
Do not loosen factory-fitted threaded cable and hose screw fittings on the casing. Otherwise, the anti-flooding function cannot be ensured.
Loosen union nut and push onto the pressure hose. Tighten the union nut of the pressure hose slightly using tools. Remove black closing cap.
Remove closing cap.
Plug in electric plug connection straight. Tighten union nut by hand.
INFO! The union nut must not be tightened using pliers.

INFO! The battery fuse is attached to the inside of the casing with adhesive tape.
NOTICE! Depending on the length of the connection cable, a jumper may be required to make a connection onto the control. An incorrect jumper position can lead to malfunctions. Back flow protection is no longer ensured.
When using the cable set (20 m, art.-no. 483 500), place jumpers onto both contacts (see illustration).
Handling
Grundfix Plus Control backflow trap type 3 20 from 41
Page 21
When using cables under 8 m in length, only attach jumper to one contact (see graphic, factory condition).
The control unit is provided with two potential-free outlets, through which acoustic and optical alarm devices can be connected.
Both contacts function as N.O. The alarm contact (clamping strip con­nection 7/8) at "Rück (Back)" is closed in the event of back flow. The fault indicating contacts (clamping strip connection 9/10) at "Stör (Fault)" closes when an operating fault is reported.
Observe the following when connecting on-site alarm devices:
n When allocating the contacts, ensure that a maximum current of
500 mA / 24 V is not exceeded.
n Allocation of the outlets must only take place using safety low
voltage and galvanic separation of the network.
n Only connect purely ohmic loads. n The use of a safety transformer in accordance with VDE 0551 or
DIN EN 60742 is permitted.
3.3 Commissioning

When the rechargeable battery charge is failing, the control unit behaves as follows:
n Rechargeable battery charge falls below 11.8 V – motor-powered
flap closes
n Rechargeable battery charge falls below 10.5 V – control and display
switch off (deep discharge protection). The backflow function is no longer active.

3.6.2 Maintenance
DIN 1986-3 requires "Maintenance" of the system twice a year to ensure safe operation.
Requirements:
n Maintenance work is not possible in battery operation as the power
loss is too great.
n Maintenance must be carried out by a professional. n Only use original parts for repairs, maintenance and extensions. n Replace defective components, do not repair. n When using cameras and cleaning devices (cleaning spiral, high-
pressure cleaner), protect the backflow trap against mechanical damage.
n Only begin maintenance work when is certain that there is no back
flow situation and the drainage fittings upstream from the Backflow trap are not being used.
In normal operation, the control shows that maintenance is due every 4320 operating hours (=180 operating days).
Display:
„Perform maintenance“
The acoustic signal can be switched off by pressing the buttons T1
„Sound off“
and T3. The display screen goes blank after maintenance
has been carried out. There is a pressure switch in the lid of the Grundfix Plus control, which

The buttons should only be used if the lid is firmly screwed onto the Grundfix Plus-Control.
