4. Sąranka ir diegimas
Tinkamas siurblio montavimas yra labai svarbus jo veikimui ir ilgaamžiškumui.
4.1. Vietos pasirinkimas
- Siurblį montuokite sausoje, gerai vėdinamoje vietoje, apsaugotoje nuo tiesioginių oro sąlygų.
- Ensure sufficient space around the pump for ventilation, maintenance, and access to connections.
- Mount the pump on a stable, level surface to minimize vibration.
4.2. Santechnikos jungtys

2 paveikslas: Į viršų view of the FORAS PLUS P5A-150/5 pump, highlighting the inlet and outlet connections. The image shows the stainless steel pump housing with threaded ports for water intake and discharge.
- Suction Line (Inlet): Connect a 1" G (25 mm) pipe to the suction port. Ensure the suction line is airtight to prevent air ingress, which can affect self-priming.
- Discharge Line (Outlet): Connect a 1" G (25 mm) pipe to the discharge port. Install a check valve if the pump is used to draw water from a lower level to prevent backflow.
- Visoms jungtims naudokite tinkamą sriegių sandariklį, kad išvengtumėte nuotėkių.
4.3. Elektrinis sujungimas
- The pump operates on 230 V AC, 50 Hz.
- Connect the pump to a dedicated circuit protected by a residual current device (RCD) and appropriate circuit breaker.
- Užtikrinkite tinkamą įžeminimą.
4.4. Siurblio užpildymas
Although self-priming, it is recommended to fill the pump casing with water before the first start-up or after extended periods of disuse to facilitate initial priming. Remove the priming plug (if present) or fill through the discharge port until the casing is full, then replace the plug.
5. Naudojimo instrukcijos
5.1. Pradinis paleidimas
- After ensuring all connections are secure and the pump casing is filled with water, switch on the power supply.
- The pump should start and begin to draw water. Allow a few minutes for the pump to fully prime and establish a steady flow.
- If the pump does not prime within a few minutes, switch it off, check for air leaks in the suction line, and re-prime the casing.
5.2. Normalus veikimas
- Monitor the pump for unusual noises or vibrations.
- Ensure the pump is not running dry, as this can cause severe damage.
- The pump is designed for continuous operation within its specified limits.
5.3. Išjungimas
- To stop the pump, simply switch off the power supply.
- For extended periods of non-use, especially in freezing conditions, drain the pump and associated pipework to prevent frost damage.
6. Priežiūra
Reguliarus siurblio aptarnavimas užtikrina optimalų veikimą ir prailgina jo tarnavimo laiką.
- Reguliarus patikrinimas: Periodically check all connections for leaks and ensure electrical cables are in good condition.
- Valymas: Keep the pump exterior clean and free from debris to ensure proper motor cooling.
- Žieminimas: In areas subject to freezing temperatures, drain the pump completely by removing the drain plug (if present) or disconnecting the pipes. Store the pump in a frost-free environment.
- Impeller and Seal Check: If performance degrades, inspect the impeller for blockages or wear, and check the mechanical seal for leaks. This typically requires professional service.
