Operating instructions filling combination

Range of use

The BA filling combination is used to automate the filling process in hot water heating
systems.
The built-in BA system separator according to EN 1717 prevents the heating water from
flowing back into the drinking water pipe. In this combination, the direct fixed connec-
tion to the heating system is approved according to EN 1717.
The integrated pressure reducer ensures the correct and constant pressure of the sys-
tem.

Version

The BA filling combination consists of integrated shut-off on the inlet and outlet side,
BA system separator to EN 1717, drain funnel, test devices, pressure reducer, dirt trap
and pressure gauge. Adjustment range of the pressure reducer between 1 and 5 bar.
Screw connections on both sides.
Housing made of pressed brass. Internal parts and drain funnel made of high-quality
plastic and NBR.
The BA filling combination includes all the components specified in EN 1717 for con-
necting the drinking water pipe directly to the heating circuit.
The built-in pressure reducer ensures a constant set outlet pressure so that the hea-
ting system is protected against unwanted overpressure during the filling process.
After completion of the filling and venting process, the integrated shut-off should be
closed to prevent uncontrolled refilling of the heating system.

Installation

The connection pipe of the Filling combi BA must be designed in such a way that no
stagnation occurs.
Before installing the Filling combi BA, the pipeline must be carefully flushed. The
fitting must be installed in the pipeline in such a way that the drain funnel points
vertically downwards so that the escaping water can run off with a free downward
gradient.
An easily accessible installation location simplifies maintenance and inspection. En-
sure that the installation location is protected from flooding and frost and is well
ventilated. The drain pipe must be provided with sufficient capacity.
In order to ensure a permanent and perfect function, we recommend the installation
of a drinking water filter according to EN 13443, part 1 immediately after the water
meter.
The maintenance intervals of the BA Plus filling combination must also be observed.
For the connection of the funnel to the waste water system, the valid standard EN
12056 must be observed.

Setting Pressure reducer

NOTE
Please note that the pressure reducer of the BA filling combination is facto-
ry-set to 1.5 bar. Please remember: The inlet pressure must be at least 1 bar
higher than the desired system pressure.
The pressure reducer can be adjusted as follows:
If a lower system pressure than 1.5 bar is desired, loo-
sen the locking screw in the adjusting handle of the
pressure reducer and turn it to the initial position in the
direction of the arrow minus (-).
After the appropriate initial situation has been rea-
ched, open the inlet valve (1) to pressurise the fitting,
the outlet side (2) remains closed.
Now turn the adjustment handle towards plus (+) to
increase the filling pressure.
Now set the desired system pressure by turning the
adjustment handle SLOWLY (due to the sensitivity of
the manometer) in the direction of plus (+).
After reaching the desired pressure value, tighten the
locking screw again.
Now you can open the outlet valve (2).
