2. Sigurnosna uputstva
Always observe the following safety precautions to prevent personal injury and damage to the pump.
- Ensure the pump is installed by qualified personnel in accordance with local regulations and standards.
- Isključite napajanje prije izvođenja bilo kakvih radova na instalaciji, održavanju ili popravci.
- Do not operate the pump dry; ensure it is always primed with water before starting.
- Zaštitite pumpu od temperatura smrzavanja.
- Osigurajte pravilno uzemljenje električnog priključka.
- Do not use the pump for flammable, corrosive, or explosive liquids.
3. Raspakivanje i pregled
- Pažljivo izvadite pumpu iz ambalaže.
- Inspect the pump for any visible damage that may have occurred during transit. If damage is found, contact your supplier immediately.
- Provjerite da li su prisutne sve komponente navedene na listi za pakovanje.
4. Instalacija
4.1 Mechanical Installation (Plumbing)
- Mount the pump on a solid, level surface to minimize vibration.
- Ensure the pump is installed in a dry, well-ventilated area, protected from direct sunlight and adverse weather conditions.
- Use pipes of adequate diameter to avoid excessive pressure drops. The inlet and outlet connections are 1 inch.
- Install a foot valve with a strainer on the suction line to prevent debris from entering the pump and to maintain prime.
- Ensure all pipe connections are airtight to prevent air leaks, which can affect pump performance.
- Install isolation valves on both suction and discharge lines for easier maintenance.
4.2 Električni priključak
- The pump requires a three-phase 400V, 50Hz power supply.
- Electrical connections must be performed by a qualified electrician in compliance with local electrical codes.
- Osigurajte da napajanje odgovara snazi pumpe.tage i ocjene frekvencije.
- Install appropriate circuit breakers or fuses for motor protection.
- Connect the pump to a properly grounded electrical system.
- Verify the motor's rotation direction. If incorrect, reverse two of the phase wires.

5. Podešavanje
- Punjenje pumpe: Before initial startup, completely fill the pump casing and the suction line with clean water through the priming port. This is crucial to prevent dry running.
- Provjerite ima li curenja: After filling, inspect all connections for any leaks.
- Provjera napajanja: Briefly turn on the power to check the motor's rotation direction. If the rotation is incorrect (e.g., indicated by a label or arrow on the motor), immediately turn off the power and reverse two of the phase wires.
6. Uputstvo za upotrebu
- Pokretanje pumpe: Ensure the pump is fully primed. Open the discharge valve slightly, then switch on the power. Gradually open the discharge valve completely once the pump is running smoothly.
- Nadgledanje: During operation, monitor for unusual noises, excessive vibration, or leaks. Ensure the pump is delivering water at the expected flow and pressure.
- Zaustavljanje pumpe: Close the discharge valve, then switch off the power.
- Produženo gašenje: If the pump will be out of service for an extended period, especially in freezing conditions, drain all water from the pump and piping to prevent damage.
7. Održavanje
Redovno održavanje osigurava optimalne performanse i produžava vijek trajanja pumpe.
- Redovni pregled: Povremeno provjeravajte ima li curenja, neobičnih zvukova ili vibracija.
- čistoća: Keep the pump and motor free from dust and debris to ensure proper cooling.
- Nožni ventil/filter: Inspect and clean the foot valve strainer regularly to prevent blockages.
- Zimljenje: In areas prone to freezing, drain the pump and associated piping completely or protect them from freezing temperatures.
- Profesionalna usluga: For internal component inspection or replacement (e.g., seals, bearings), consult a qualified service technician.
