5. Sąranka ir diegimas
Correct installation is crucial for the pump's performance and longevity.
Diegimo vieta:
- The pump must be installed in enclosed spaces or locations protected from atmospheric influences (e.g., rain, frost, direct sunlight).
- Ensure the installation area is well-ventilated and provides sufficient space for maintenance.
- Mount the pump on a stable, level surface to minimize vibration.
Santechnikos jungtys:
- Connect the suction and discharge pipes securely to the pump's 1-inch (25 mm) nozzles.
- Use appropriate sealing materials (e.g., PTFE tape) to ensure watertight connections.
- Install a foot valve with a strainer on the suction line if drawing water from a well or tank to prevent debris entry and maintain prime.
- Ensure the suction line is as short and straight as possible to minimize friction losses.
Elektros jungtis:
- Connect the pump to a 230V AC, 50Hz power supply.
- Ensure the electrical circuit is protected by a suitable circuit breaker and residual current device (RCD).
- Verify that the power supply matches the pump's specifications.
- Siurblys turi būti tinkamai įžemintas.

6. Naudojimo instrukcijos
Follow these steps for safe and effective operation of your FORAS PE50F pump.
Siurblio užpildymas:
- Before the first start-up, or if the pump has run dry, it must be primed.
- Atsukite užpildymo kamštį (paprastai esantį siurblio viršuje c)asing).
- Užpildykite siurblį casinvisiškai pripildykite švariu vandeniu, kol jis perpils.
- Pakeiskite ir priveržkite užpildymo kamštį.
- Ensure all valves on the suction and discharge lines are open.
Siurblio paleidimas:
- After priming, connect the pump to the power supply.
- Switch on the power. The pump should start immediately.
- Monitor the pump for any unusual noises or vibrations. If detected, switch off the pump immediately and investigate.
- Allow the pump to run for a few minutes to ensure stable operation and check for leaks.
Siurblio sustabdymas:
