4. Opsætning og installation
4.1 Placering
Install the pump in a dry, well-ventilated area, protected from direct sunlight, rain, and freezing temperatures. Ensure sufficient space around the pump for ventilation and maintenance.
4.2 Elektrisk tilslutning
- The pump operates on single-phase 110V or 220V AC, 60Hz. Verify your power supply matches the pump's requirements.
- Sørg for, at det elektriske kredsløb er beskyttet af en passende afbryder eller sikring.
- Connect the pump to a properly grounded electrical outlet.
- The motor includes a thermal overload protector.
4.3 VVS-tilslutning
- Connect 1-inch pipes to both the inlet and outlet ports of the pump.
- Use appropriate sealants (e.g., PTFE tape) on threaded connections to prevent leaks.
- Sørg for, at alle forbindelser er stramme, men overspænd dem ikke.
- Install a foot valve with a strainer on the suction line if drawing water from a well or tank to prevent debris from entering the pump and to maintain prime.
4.4 Spædning af pumpen
Before initial operation, the pump must be primed. Remove the priming plug (usually located on the top of the pump casing) and fill the pump casing completely with clean water until it overflows. Replace the priming plug securely.
5. Betjeningsvejledning
- Ensure the pump is properly installed and primed.
- Verify all plumbing connections are secure and leak-free.
- Connect the pump to the appropriate electrical power supply.
- Turn on the power. The pump should start operating and begin to move water.
- Monitor the pump for any unusual noises or vibrations during initial operation.
- If the pump fails to deliver water after a short period, turn off the power, re-prime the pump, and check for any obstructions in the suction line.

7. Fejlfinding
| Problem | Mulig årsag | Løsning |
|---|---|---|
| Pumpen starter ikke | No power; tripped circuit breaker; motor thermal overload activated. | Check power supply; reset circuit breaker; allow motor to cool down. |
| Pumpen kører, men der kommer ikke noget vand ud | Pump not primed; air leak in suction line; clogged suction strainer; insufficient water supply. | Re-prime the pump; check suction line connections; clean strainer; ensure adequate water source. |
| Reduceret flow eller tryk | Partial blockage in plumbing; worn impeller; air in system. | Inspect and clear plumbing; consult a qualified technician for impeller inspection; re-prime. |
