Star/delta start: adjust the thermal relay to a current-carrying capacity equivalent at the
latest to 0,58 times the nominal absorption indicated on the rating plate. If the motor
protector goes off while the aerator is working, check the fuses before trying to start it
again.
Do not ever force the aerator to work without having solved the problems. If necessary
consult a technician of S.C.M. Tecnologie.
Direction of rotation
After every new connection and lack of voltage check the rotation direction of the motor
(SEE PICTURE 4 ON PAGE 27). The rotation direction of the impeller must be clockwise
when watching the aerator from the top (in case connect the machine and check its rotation
direction before submerging it). If the rotation direction is wrong, the motor does not
aspirate air correctly, causing an overcharge with current absorption. If this rotation
direction is wrong you need to invert the two ends of the cable on the control panel.
(CONSULT THE PARAGRAPH 5.1-PAG. 8).
6. USE AND MAINTENANCE
6.1 START
If the starting unit is unable to start, do not insist repetedly as this could only damage
the component. Identify the malfunction and repair the damage.
If an indirect starting system is used, the starting transaction must be brief never more
than a few seconds.
6.2 RUNNING AND INSPECTIONS
ATTENTION:
Once installed, the SC aerator will not require particular maintenance.
However to ensure a continuous regular operation check periodically
that the aerator hydraulics are not clogged by solids and/or thready
substances in the pump liquid. Also conduct regular preventive
maintenance inspections at least once every 5,000-10,000 hours service
depending on whether duty is more or less heavy. Check the following:
- The electrical insulation of the motor-power cable complex
(consult the “Electrical connections" paragraph);
- The condition of the oil (consult the “Maintenance” paragraph);
- The condition of the hydraulic components
(consult the “Maintenance” paragraph);
You are also advised to check the efficiency of the electric panel (when
installed) every 6-12 months. If operative faults are detected, identify
their causes and proceed with repairs, as indicated in this manual.
