8. ഇൻസ്റ്റലേഷനും സജ്ജീകരണവും
Proper installation is crucial for the motor's performance and longevity. It is recommended that installation be performed by qualified personnel.
- പ്രീ-ഇൻസ്റ്റലേഷൻ പരിശോധന: Verify that the motor and all components are free from damage. Ensure the power supply matches the motor's voltage requirements (230V single-phase or 400V three-phase).
- കേബിൾ കണക്ഷൻ: Connect the power cable securely, ensuring watertight seals. For single-phase models, integrate the provided capacitor as per wiring diagrams (not included in this general manual, refer to product-specific wiring instructions).
- Flange Coupling: Securely attach the motor to the pump using NEMA-compliant flange connections.
- Lowering into Borehole: Carefully lower the motor and pump assembly into the borehole, ensuring it remains vertical and does not snag on the casing. Maintain the minimum flow rate for motor cooling (8 cm/s) around the motor.
- നിമജ്ജന ആഴം: Do not exceed the maximum immersion limit of 100 meters. Ensure the motor is fully submerged during operation.
- ഇലക്ട്രിക്കൽ കണക്ഷൻ: Connect the power cable to a suitable control panel with appropriate overload protection. Ensure proper grounding.
9. പ്രവർത്തന നിർദ്ദേശങ്ങൾ
Once installed, the motor is designed for continuous service (S1) within its specified application limits.
- പ്രാരംഭ ആരംഭം: After installation, perform a brief test run to ensure correct rotation and operation. Monitor current draw.
- തുടർച്ചയായ പ്രവർത്തനം: The motor is designed for continuous duty. Avoid frequent starts and stops; limit to 20 starts per hour at regular intervals.
- താപനില നിരീക്ഷണം: Ensure the liquid temperature does not exceed +35 °C to prevent overheating.
- ഡ്രൈ റണ്ണിംഗ്: Never operate the motor without being fully submerged in water, as this will cause severe damage.
10. പരിപാലനം
The Pedrollo submersible motor is designed for minimal maintenance. However, periodic checks are recommended.
- പതിവ് പരിശോധന: Periodically check the control panel for proper functioning of protection devices.
- കേബിൾ സമഗ്രത: Inspect the power cable for any signs of wear or damage during any retrieval of the pump.
- Oil Check: The motor is oil-filled and sealed. No user-serviceable oil changes are required. If oil leakage is suspected, contact qualified service personnel.
- വൃത്തിയാക്കൽ: If the pump assembly is retrieved, clean any accumulated debris from the motor's exterior to ensure efficient cooling.

- Check for tripped overload protection.
- Motor Runs But No Water/Low Flow:
- Ensure the pump is properly connected to the motor and is not blocked.
- Check water level in the borehole; ensure motor is fully submerged.
- Inspect piping for blockages or leaks.
- Motor Overheats/Trips Overload:
- Verify the liquid temperature is within limits (+35 °C max).
- Ensure sufficient water flow for motor cooling (min 8 cm/s).
- Check for excessive starts per hour.
- Inspect for mechanical binding in the pump or motor.
