16.Parameterise the time and duration of the test run on the digital timer in
the switch cabinet (refer to Chapter 8.3.1.1).
17.If a rinsing device is necessary, set the time and duration for rinsing the
inlet line. To do so, parameterise the second channel of the digital timer.

8.3.1 Settings

8.3.1.1 Parameterise the time and duration of the test run
Refer to the description in the instructions included for the timer.
1. First check date and time (item "Setting date and time").
2. Then procede as described under the item "Programming short operation
cycles (impulses)" and in "Program example impulses". (default setting:
Monday 0.00h, duration 59s).
8.3.1.2 Set the amount of refilling water with the throttle valve
For systems with a pump volume of 18m
3
be set to 25m
/h on the throttle valve as a function of the supply pressure.
For systems with a pump volume of 36m
be set to 50m
3
/h on the throttle valve as a function of the supply pressure
8.3.1.3 Setting the power-off delay
The power-off delay can be set to values from 5 to 100 s (refer to documen-
tation of cabinet).
8.3.1.4 Setting the rinsing duration
Flushing of the potable water pipeline connected upstream can be activated
by setting the digital timer in the switching cabinet via the solenoid valve.
The flushing water is discharged though the integrated overflow. The flus-
hing time is estimated with respect to the required flushing volume (refer to
the following figure). For larger flushing volumes (more than 200 l), it can be
increased by 7 l (25 m

Switching the system on

1. Secure the shut-off valves of the in and output against being closed.
2. Operate the main switch to supply the system with voltage.

Start-up checklist

Work steps
1
Read instructions.
2
Check the voltage supply and compare with the values
on the type label.
3
Check the grounding system (by measurment).
4
Check the mechanical connection to the water supply
system. Tighten the flanges and the screws.
5
Fill and ventilate the compact booster unit from the input
side.
6
Check the refilling.
7
Check the switching device to see if all electrical lines
are still securely plugged into the clamps.
8
Check the rotation direction.
9
Check the switch-on and switch-off pressure, correct if
necessary.
10
Check if the water shortage/dry running protection is
functioning.
11
Venting the pump a second time, after it has been run-
ning for a few minutes (5 to 10).
12
Set the switch to automatic.
13
Check the precharge pressure (refer to Chapter 9.3.1).
14
Secure the shut-off valves of the in and output lines
against being closed
15
Circumstances regarding the system that are not the
same as stated in our documentation or ordering data,
have to be noted in the start-up protocol.
16
Fill out the start-up protocol with the operator and show
the operator how the machine functions.
