Oxiperm Pro hydraulic connections
For nominal width of hose connections, see section
.
2.5.1 Device connections
The
Oxiperm Pro
has connections for the following:
•
dilution water hose at the solenoid valve (fig. 4, pos. 26)
•
hoses for both suction lances on the suction side of the
chemical pumps (fig. 4, pos. 5b and 6b)
•
dosing line from the dosing pump to the injection unit at the
main line or to the flow control instrument in the mixing
module (fig. 4, pos. 14)
•
hose at the drain cock of the reservoir tank (only installed for
flushing and ventilation) (fig. 4, pos. 8b).
2.5.2 External dosing pump connection
If the system has been supplied without a dosing pump, the
dosing line of an external dosing pump is connected to the
reservoir tank.
2.5.3 Measuring cell connections
The measuring cell is hydraulically connected to the main line.
After dosing, the ClO
2
concentration, temperature and pH/redox
value of the sample water are measured in the measuring cell.
The measuring cell has connections for the following:
•
hose from the sample-water bleeding point to the measuring
cell
•
hose from the measuring cell to the drain.
See the installation and operating instructions for the measuring
cell.
2.5.4 Measuring module connections
The measuring module is hydraulically connected to the main
line.
The measuring module has connections for the following:
•
hose from tapping sleeve 1 to the measuring module and
hose from the measuring module to tapping sleeve 2 at the
main line.
See the installation and operating instructions for the measuring
module.
2.5.5 Mixing module connections
The mixing module is hydraulically connected to the main line and
the
Oxiperm Pro
.
The mixing module has connections for the following:
•
dosing line from the
Oxiperm Pro
dosing pump to the
injection unit in the mixing module.
•
hose from tapping sleeve 1 to the mixing module and hose
from the mixing module to tapping sleeve 2 at the main line.
See the installation and operating instructions for the mixing
module.
2.6 Power supply connections and electronic
connections
The
Oxiperm Pro
disinfection system is equipped with an
electronic control system from Grundfos Alldos. See section
2.8 Control and display elements
The control system has connections for the following:
•
power supply cable to the main switch
•
cable from the water flow meter or flow meter
•
cables for measuring cell AQC-D1 or AQC-D6, if necessary:
– measuring electrode, from the counter-electrode
– sample-water deficiency sensor
– Pt100 sensor
– pH electrode, if necessary (for pH or redox) (AQC-D1 only)
– cleaning motor (AQC-D1 only)
•
or the cables from the measuring module, if necessary:
– measuring electrode and counter-electrode
– water deficiency sensor
– Pt100 sensor
•
or the cable from the mixing module, if necessary:
– flow controller.
For additional connections, see the separate service instructions,
sections 4. Installation and 4.6 Connecting the electronic
components.
2.7 Operating modes
During commissioning, the disinfection system is set up
according to the application. When switched on and the ClO
2
production is started, system operation is fully automatic using
menu commands.
For ClO
2
production, two operating modes can be set:
•
continuous operation ("continuous" mode)
•
dosing once ("once" mode).
Dosing is controlled automatically by the controller. In manual
operation, the controller can be switched off. See section
Other functions in manual operation can only be used with the
service code.
