Warnings for Peripheral Pumps

• Before Installation:
  • Check rotating parts to ensure they turn freely.
  • If blocked, use a screwdriver to gently turn the motor shaft.
• After Long Periods of Inactivity:
  • Turn off power and manually rotate the shaft to ensure free movement before restarting.

Installation Guidelines

1. Location:
   • Install in a dry, well-ventilated area protected from weather.
   • Ambient temperature should not exceed 40°C.
2. Mounting:
   • Fix the pump on a solid, flat surface using suitable bolts to avoid vibration.
   • Ensure the pump is installed horizontally for proper bearing operation.
3. Piping:
   • Use pipes with diameters not smaller than the pump inlet/outlet.
   • Install a foot valve on the suction side.
   • Ensure the intake pipe is airtight and immersed in water by at least 0.5 meters.
   • For suction depths >4 meters or long horizontal stretches, use a slightly upward-sloping intake hose.
   • Fit a non-return valve on the delivery side to prevent water hammer.
4. Sand Filter:
   • Install a sand filter if the pump is used in sandy environments to protect the impeller.

Electric Connection

• Safety First:
  • Follow safety regulations and wiring diagrams inside the terminal box.
  • Ensure the mains voltage matches the motor plate specifications.
  • Use a skilled electrician for installation.
• Single-Phase Motors:
  • Equipped with built-in thermal overload protection.
• Three-Phase Motors:
  • Require remote-control motor protectors calibrated to the current on the motor plate.
• Voltage Tolerance:
  • Permitted voltage variation is ±10% of the rated voltage.

Starting Up the Pump

1. Priming:
   • Fill the pump completely with clean water through the filler hole to lubricate the mechanical seal.
   • Dry operation can damage the seal.
2. Check Rotation Direction:
   • For three-phase motors, ensure the impeller rotates clockwise (viewed from the motor side).
   • If rotation is incorrect, swap any two wires on the terminal board.

---

Precautions

• Start Limit:
  • Do not start the pump more than 20 times per hour.
• Frost Danger:
  • Empty the pump body through the drain cap if the pump remains inactive at temperatures below 0°C to prevent cracking.
  • Also advisable for prolonged inactivity at normal temperatures.

---

Maintenance and Cleaning

• Normal Operation:
  • No specific maintenance is required.
• Cleaning:
  • Clean hydraulic parts if a drop in performance is observed.
• Dismantling:
  • Only skilled personnel should dismantle the pump.
  • Always disconnect the pump from the power supply before maintenance.
