System is too loud
Tank overflows
10.1 Measures for elimination of
pressure surges
10.1.1Enlargement of the inlet line
According to EN 806-5 for amounts > 0.5l/s a minimal pipe
inner diameter of 20mm is to be selected.
10.1.2Setting pressure reducing valve
If static pressure of 5 bar can be read on the pressure gauge
and the pressure drops to 2.5 bar when the valve is opened,
then the static pressure must be lowered by 1 bar. Pressure
surges occur by pressure differences larger than 2 bar.
10.1.3Throttle pressure surge
If a stop valve or pressure reducing valve is installed in the
drinking water line upstream of the system, then it has to be
throttled until the pressure surge disappears. The
disadvantage of this method is the small feed amounts. It
must be checked, whether the feed amount is sufficient for
normal use. The water shortage monitor, however, must not
be activated at maximal withdrawal. Should the water
shortage monitor nevertheless be activated, then the
downstream side must be throttled as well.
10.1.4Membrane pressure expansion
vessel
Install an 8l - membrane pressure expansion vessel in the line
ahead of the system inlet. With this container, severe
pressure drops from thin lines are diminished and surges are
contained without throttling the amount.
11 Shut-down, disassembly, restart
11.1 Shutting down the compact booster
unit
CAUTION!
Danger of injury from electric voltage.
High shock currents and burns from direct and indirect
contact with live parts.
 Turn off the power supply before shut down the
compact booster unit and secure it from being turned
on.
1. Disconnect system from the electric power supply and
secure against being started.
2. Dismantle the system properly.
3. Close drinking water inlet and pressure line.
4. Rinse the system properly.
5. Let system drain.

Possible cause
Foreign particles in pump control
Pump lies against the safety screws Adjust pump by hand, so that the pump is
Contamination in valve
Elimination
Clean pump control and replace if
necessary
not lying against the screws
Eliminate dirt/limescale in valve and replace
floater if necessary
11.2 Restarting the compact booster unit
Please note the procedures in chapter 7

12 Storage

12.1 Short-term storage
Short-term storage is possible without further preparation
under the specified environmental conditions.
12.2 Storage/Preservation
CAUTION!
Damage during storage caused by frost, humidity,
dirt, UV radiation or pests
Corrosion/Contamination of the system!
 Protect the system against frost, do not store outside.
CAUTION!
Damp, dirty or damaged openings and junctions
Danger of leaks and damaging the system!
 Uncover openings in the system only during
installation.

12.3 Storage conditions
