3. Installation og opsætning
Proper installation is crucial for the pump's performance and longevity. It is recommended that installation be performed by a qualified technician.
Generelle retningslinjer:
- Beliggenhed: Install the pump in a dry, well-ventilated area, protected from direct sunlight and frost. Ensure sufficient space for maintenance.
- Montering: Securely mount the pump on a stable, level surface to minimize vibration.
- Rørføring: Use pipes of appropriate diameter to avoid excessive pressure loss. Ensure all connections are airtight to prevent air ingress, which can affect pump performance.
- Sugeledning: The manometric suction lift should not exceed 7 meters. Install a foot valve with a strainer at the end of the suction line to prevent debris from entering the pump and to maintain prime.
- Elektrisk tilslutning: The pump requires a three-phase, 400 V, 50 Hz power supply. Connect the pump to a suitable electrical circuit with appropriate overload protection, as per local electrical codes. Ensure the motor rotation direction is correct (check arrow on motor casing).
- Grunding: Before initial startup, the pump body and suction line must be completely filled with water to ensure proper operation.

4. Betjeningsvejledning
Once properly installed and primed, the pump is ready for operation.
- Indledende opstart: After priming, switch on the power supply. The pump should start smoothly. Monitor for any unusual noises or vibrations.
- Kontinuerlig drift: The pump is designed for continuous operation (S1). Ensure the liquid temperature remains within -10 °C to +40 °C and ambient temperature does not exceed +40 °C.
- Overvågning: Regularly check the pump for leaks, unusual noises, or excessive heat.
- Nedlukning: To stop the pump, switch off the power supply. For extended periods of non-use, especially in freezing conditions, drain the pump and pipes to prevent damage.
5. Vedligeholdelse
Regelmæssig vedligeholdelse sikrer optimal ydeevne og forlænger pumpens levetid.
- Regelmæssig inspektion: Periodically inspect the pump for any signs of wear, corrosion, or damage. Check electrical connections for tightness.
- Rensning: Hold pumpen og motoren fri for støv og snavs for at sikre korrekt afkøling.
- Dræning: In areas prone to freezing, drain the pump and associated piping completely before winter to prevent ice damage.
- Seglkontrol: Monitor the mechanical seal for any leaks. Minor dripping is normal, but excessive leakage may indicate a worn seal that requires replacement.
- Professionel service: For complex repairs or internal component replacement, contact a qualified service technician.
