6. Start-up
To start up a booster set Hydro 1000, follow this procedure:
1.
Connect water and electricity supplies.
2.
Check that the precharge pressure in the diaphragm tank is
equal to the minimum cut-in pressure.
3.
Close the discharge valves of the pumps and prime the
booster set and the suction pipe.
4.
Adjust the pressure switches according to the desired dis-
charge pressure.
5.
Check that the DIP switch setting corresponds to the number
of pumps installed.
6.
Switch on the electricity supply.
7.
Start pump 1 by pressing the button on the front cover.
8.
Pump 1 will now start.
9.
Check the direction of rotation of the pump. In case of incor-
rect rotation, interchange two phases of the electricity supply.
10. Vent the pump while slowly opening its discharge valve.
11. Repeat points 7 to 10 for all pumps.
12. Release the pumps for operation by pressing the buttons on
the front cover.
Hydro 1000 is now ready for operation.
7. Maintenance
7.1 Maintenance of booster set
See installation and operating instructions for CR pumps.
7.2 Maintenance of Control 1000
The Control 1000 is maintenance-free.
7.3 Checking the precharge pressure
To ensure reliable and correct operation, including the frequency
of starts and stops, the precharge pressure of the diaphragm tank
should be checked regularly (at least twice a year).
