Notes on installation
We recommend connecting the pump
control to the house water pipe via a
flexible hose.
Safety valve to pre-
vent water leakage if
the
diaphragm
bursts (do not work
on or change!).
The control must be
oriented upwards ac-
cording to the direction
of the arrow.
The controller can be in-
stalled directly on the pump
or between the pump and
the first tapping point.
Before
the
start of the ma-
chine, the suc-
tion hose and
pump
filling
must
be
checked!
Pump pressure
The automat is set to
an inlet pressure of
1.5 bar. The pump inlet
pressure must normally
be 0.5 bar higher than
the starting pressure,
i.e., at least 2 bar.
Do not place any extraction
points between the pump and
switch.
The
machine
is
equipped with a test
valve to protect the pip-
ing system from pres-
sure loss.
If the water column be-
tween the pump and the
highest point of the pipe
exceeds 15 m, the au-
tomat cannot be in-
stalled directly at the
pump. The machine
must then be installed
at a height where the
overhanging water col-
umn is shorter than
15 m. For example: If
the water column is
20 m, the machine must
be installed at least 5 m
above the pump.
