Order number:      

2 | Appropriate application

The Euro system separator, construction design BA, is a safety device to be in­stalled in water pipes if special withdrawal points or appliances are connected to the
drinking water supply. The Euro system separator prevents the back-flow, back­pressure and back-suction of modified drinking water into the drinking water net­work. The construction design BA is approved as safety device for systems up to
and including liquid category 4 as per DIN EN 1717, part 5.2 (refer to chapter B;
classification of liquid categories).

Attention! System separators are safety devices. They protect the drinking water
from modified drinking water. They can only work reliably provided inspections and
maintenance are carried out at regular intervals.

3 | Functional description

Fig. C-1: Detailed drawing of
Euro system separator GENO-DK 2-Mini

The system separator consists of a housing (item 1), a hous­ing lid with connection threads for test sockets (item 2), a
non-return valve on the inlet side (item 3), a non-return valve
on the outlet side (item 4) as well as a discharge valve
(item 5).

The two non-return valves separate three different zones of
three different pressures:

Primary pressure zone (item A): Area upstream of the non-re­turn valve on the inlet side

Middle pressure zone (item B): Area between the non-return
valves

After-pressure zone (item C): Area downstream of the non­return valve on the outlet side



Note: Prior to start- up, the air above the membrane must be released in order to
ensure safe operation (item 7).

Attention! If the bulge of the cap sieve (item 6) protrudes into the system separator,
the non-return valve (item 3) on the inlet side might be actuated, releasing perma­nent draining. Therefore, it is compulsory that the cap sieve is installed with the
bulge directing opposite the flow direction.

D Installation and start-up

1 | General installation instructions

 Please observe the local installation guidelines and the general regulations.

 The installation site must be accessible for maintenance work, flood- and frost-

proof and ensure the system's protection from chemicals, dyes, solvents and
vapours.

 Installation according to its nominal width in pipes of similar dimensions.

 According to DIN EN 806-2, quick-closing shut-off fittings that might cause pos-

itive or negative water hammer may only be used for continuous actuation in
water installations if the max. admissible water hammer pressure and operat­ing pressure are taken into account. Exceptions apply for fittings that are used
for test purposes only and are operated by experts.

Attention! Dirt and corrosion particles might cause malfunctions or damage the
system separator. Prior to start-up, flush the feed pipe at maximum performance.

2 | Water installation

Binding rules

The installation of a system separator represents a major interference with the
drinking water system. Therefore, only authorised experts may install such systems.

Preliminary work

1. Unpack all system components.

2. Check for completeness and soundness.

 Install as per the installation drawing (fig. D-1).

 Make sure that built-in parts (e. g. EBRO flaps) installed upstream or downstream

of the device to not protude into the system separator and damage internal com­ponents.

 Make sure that the system separator's cap sieve is installed with its bulge direct-

ing opposite the flow direction (refer to fig. F-1).



Note: Install strainer/fine filter directly upstream of the system separator, other­wise malfunctions in the system separator may occur.

Attention! Observe the flow direction.

 Only install the system separator horizontally and without any loads and

stresses.

 Provide a drain connection as per the technical specifications.

 Make sure there is a free outlet and the water is discharged without back-pres-

sure.

3 | Start-up

1. Slowly open the shut-off valves (items 1 and 4) upstream and downstream of
the system separator. Afterwards, the system separator moves to its operat­ing position. Make sure that the discharge valve (item 5) is closed.

2. Completely deaerate the system separator by opening the bleeding screws
(item 3).

3.

Perform a visual check. Make sure that no water leaks from the device any­where.

4 | Functional check

After the successful start-up of the system separator, close the shut-off valve
(item 1). Pressure relief in the primary pressure zone is initiated by opening the
discharge valve (item 5).



Note: Afterwards, the system separator must go into separating position and
thereby drain the middle pressure zone.

Afterwards, close the discharge valve (item 5) and slowly open the shut-off valve
(item 1). Then the system separator must move into the operating position again,
and must be completely tight.

E Troubleshooting

Even carefully designed and manufactured technical systems that are operated
properly, may experience malfunctions. The table below provides an overview of
possible problems that may occur during the operation of system separators and
indicates the causes and their elimination.

Attention! Short-term, undefined water leakage at the discharge valve of the sys­tem separator does not represent a malfunction but is a normal control behaviour
of the system separator caused by pressure fluctuations on the inlet side in the
water supply system.



Note: In case of disturbances, e.g. permanent water leakage at the discharge
valve, proceed as per the checklist below:
Irrespective of the disturbance, you may identify the fault by systematically per­forming the individual steps.

F Maintenance, care and spare parts

1 | Basic information

In order to guarantee the reliable function of the system separator over a long pe­riod of time, some maintenance work has to be performed at regular intervals. This
applies in particular to safety fittings for the supply of drinking water where the re­quired measures are defined in the pertinent regulations and guidelines. All regula­tions and guidelines which apply at the installation site must be strictly adhered to.

Inspection and maintenance based on DIN EN 806-5 and W/TPW 135, appendix I.

 The semi-annual inspection may be performed by the operator or the installa-

tion company.

 The yearly maintenance must be carried out by an installation company or by

Grünbeck's technical service/authorised service company.



Note: A maintenance contract ensures that all the required maintenance work will
be performed in due time.

2 | Inspection

Check for tightness, visual check:

 If no water is withdrawn, no water may leak.

 If a withdrawal point is opened downstream, no leakages must occur.

3 | Maintenance

Check for tightness, visual check:

 If no water is withdrawn, no water may leak.

 If a withdrawal point is opened downstream, no leakages must occur.

Functional check:

 Close the shut-off valves upstream of the system separator. Relieve the pres-

sure from the primary pressure zone between the shut-off valve and the sys­tem separator by opening the discharge valve.

 Empty/drain off the inlet pressure zone between the closed shut-off valves and

the system separator.

 Afterwards, the system separator must go into separating position, and must

completely drain the middle pressure zone.


