ConnectionCenter 3228 All-in-one
Instructions for use

2
Field of application
The connectionCenter 3228 All-in-one is used as the basis
for refillable cartridges.
It supplies either softened, fully demineralised or deminera-
lised water with pH value stabilisation for heating systems
in accordance with VDI Guideline 2035 Part 1 and protects
heating systems against lime deposits.
It is also used to automate the filling process in hot water
heating systems.
The built-in BA backflow preventer according to DIN EN 1717
prevents the heating water from flowing back into the drin-
king water pipe.
In this combination, the direct fixed connection of drinking
water to the heating system is approved according to DIN
EN 1717.
The integrated pressure reducer ensures the correct and
constant pressure of the system.
Design
The Connection Center All-in-one contains a digital capacity
control, a shut-off valve on the inlet and outlet side, a sam-
pling connection for soft water, a hardness measuring set, a
wall bracket for installation, a BA backflow preventer accor-
ding to DIN EN 1717, tundish, testing devices and a pressure
reducer. Setting range of the pressure reducer between 1
and 5 bar. Screw connections on both sides.
Please order the already filled cartridges, which are availa-
ble in 2.5, 4, 7, 14 and 30 litre versions for HWE (heating
water softening) HVE (heating demineralisation) and HVE
Plus (pH value stabilisation) and can be refilled with the
corresponding granulate.
A conductivity sensor and pressure sensors are already in-
tegrated in the digital capacity control.
The built-in pressure reducer ensures a constant set output
pressure so that the heating system is protected against
unwanted overpressure during the filling process.
Housing made of pressed brass. Internal parts and tundish
made of high-quality plastic and NBR.
The plastic parts and elastomers in contact with the drin-
king water comply with the KTW guideline of the Federal
Environment Agency.
Installation
Mount the wall bracket on the wall.
Make sure that the water supply line is installed in such a
way that stagnation does not occur and that the escaping
water can drain off with a free gradient.
Flush the pipe carefully before installing the connection
centre.
Remove the pressure gauge plug.
Attach the wall bracket at this point of the connection
centre and lock it in place using the screw connections.
Mount the drain valve on the other side.
The wall bracket optionally can be mounted on both
sides.
An easily accessible installation location simplifies mainte-
nance and inspection. Make sure that the location is pro-
tected against flooding and frost and is well ventilated. The
drain pipe must be provided with sufficient capacity.
In order to ensure permanent and perfect functioning, we
recommend the installation of a drinking water filter accor-
ding to DIN EN 13443, Part 1 immediately after the water
meter.
The maintenance intervals of the BA backflow preventer
must be observed. For connecting the tundish to the drai-
nage system, the applicable standard DIN EN 12056 must be
observed.

„Raw water hardness“, „cartridge“, („Soft water
hardness“) must be made again!
Set the desired mixed water hardness at the blending valve.
For soft water set in direction „Soft“, for harder water set in
direction „Hard“.
Deactivate the blending valve by turning the spindle clock-
wise all the way in with a hexagon socket.
Hold the outer ring (with the indicator arrow) firmly.
Note: When the blending valve is closed, raw
water is no longer mixed in!
The system can now be filled.
Before filling, check the initial hardness of the water by
drawing 2-3 litres of water through the drain valve and
check it with the hardness measuring set.
If necessary, adjust the soft water hardness setting.
The following confirmation appears:
Press the - or button to change the value and press

(10 - 1 % remaining capacity) the message „Cartridge al-
most exhausted“ is displayed
When the cartridge is completely exhausted, the message
„Cartridge exhausted“ appears - the cartridge must be
replaced!
Adjustment of pressure
reducer
Before you can fill the system with treated water, the pres-
sure reducer may have to be adjusted.
The pressure reducer of the Connection centre All-in-one is
factory set to 1.5 bar.
Please note that the inlet pressure must be at least 1 bar
higher than the desired outlet pressure.
The pressure reducer can be adjusted as follows:
Unscrew the locking screw of the pressure reducer with a
screwdriver.
To decrease the filling pressure, turn the adjustment handle
in the direction of minus (-) and to increase in the direction
of plus (+).
The set pressure and the pressure of the heating system is
displayed in the digital capacity control.
Press the button 3 times in the main menu. Use the
key to switch between input and output pressure.
After adjustment, retighten the locking screw to prevent acci-
dental adjustment.
Note: Please note that the heating pressure is
lower than the desired filling pressure.
If necessary, reduce or increase the pressure of
the heating system to the desired filling pressure.

The ball valve on the inlet side can be turned by
180° to simplify maintenance of the strainer.
Close both shut-off valves after completing the filling process
to prevent uncontrolled refilling.
Maintenance -
Checking the separation of
the backow preventer
The isolating function as well as the function of the output
check valve must be controlled annually in accordance with
DIN EN 806, part 5, to ensure that the backflow preventer
works properly.
Remove the manometer plug of the inlet and intermediate
pressure zone (1 + 2).
Install the maintenance ball valves in place of the manometer
plugs.
Mount the needle valves of the measuring instrument (e.g.
6600.00.000) to the maintenance ball valves 1 + 2.
Mount the measuring device and open the two shut-off valves.
Close both shut-off valves for inspection.
Filling the heating system
Open the two shut-off valves of the Connection centre All-
in-one to start the filling process.

Vent the valve via the two needle valves. Then close the two
needle valves again.
Close the two shut-off valves.
Open needle valve 1 and slowly release the pressure via need-
le valve 1 (a few drops).
Close the needle valve again. Observe the tundish. The diffe-
rential pressure must be above 140mbar and the inlet back-
flow preventer (RV1) must close completely again, otherwise
there is contamination or a mechanical defect.
Open the needle valve 1 further and relieve the medium pres-
sure zone until it is completely drained.
Maintenance - inspection of
check valve 2
To test the outlet check valve (RV 2), the intermediate pressu-
re zone must first be completely drained.
Open the outlet shut-off valve.
If water drips from the tundish, there is a mechanical defect
or contamination of the outlet check valve.
In this case the backflow preventer cartridge must be cleaned
or replaced.
Close both maintenance ball valves, remove the measuring
device and reinstall the pressure gauge plugs.
Open the two shut-off valves.
