ADVARSEL! Læs alle sikkerhedsadvarsler og alle instruktioner. Manglende overholdelse af advarsler og instruktioner kan resultere i elektrisk stød, brand og/eller alvorlig personskade.
- Elektrisk sikkerhed: Ensure the power supply matches the pump's specifications (230 V). Always disconnect the power supply before performing any work on the pump. The external control box is splash-proof (IP44) but should be protected from direct water exposure.
- Installation: The pump must be fully submerged during operation. Do not operate the pump dry. Ensure the borehole diameter is at least 11 cm for proper installation.
- Vandkvalitet: This pump is designed for clear water. Do not pump flammable, corrosive, explosive, or abrasive liquids. The water temperature should not exceed 35°C.
- Børn og tilskuere: Hold børn og uautoriserede personer væk fra driftsområdet.
- Opretholdelse: Only qualified personnel should perform repairs. Use only original spare parts.
- Overbelastningsbeskyttelse: The integrated thermal protection circuit and overload switch protect the pump from damage due to overheating or overcurrent.

4. Opsætning og installation
Follow these steps for proper installation of your deep well pump:
- Prepare the Borehole: Ensure the borehole has a minimum diameter of 11 cm to accommodate the pump (10 cm diameter). The maximum immersion depth is 20 meters.
- Connect the Discharge Pipe: Attach a 1 ¼" pipe to the high-quality brass thread outlet of the pump. Ensure a secure and watertight connection.
- Sænk pumpen: Carefully lower the pump into the well or borehole. Use a strong rope or cable attached to the designated eyelets on the pump head for support. Ensure the pump is suspended at least 0.5 meters from the bottom of the well to avoid drawing in sediment. The maximum immersion depth is 20 meters.
- Position the Control Box: Place the external control box in a dry, protected location, easily accessible for operation. The control box is splash-proof (IP44) but should not be exposed to heavy rain or direct water spray.
- Tilslut til strøm: Plug the pump's power cable into the external control box, and then plug the control box into a suitable 230 V power outlet.

5. Betjening
Operating the TROTEC Deep Well Pump TDP 7500 E is straightforward:
- Indledende opstart: After installation, ensure all connections are secure and the pump is fully submerged.
- Tænd: Switch on the power using the switch on the external control box. The pump will begin to draw water.
- Overvågning: Observe the water flow. The pump has a maximum flow rate of 4800 liters per hour and can achieve a maximum pressure of 9.3 bar.
- Termisk beskyttelse: The integrated thermal protection circuit and overload switch will automatically shut off the pump if it overheats or experiences an electrical overload, preventing damage.
- Sluk: To stop the pump, switch off the power at the control box.

6. Vedligeholdelse
Regelmæssig vedligeholdelse sikrer pumpens levetid og optimale ydeevne:
- Cleaning the Dirt Screen: The pump features a stainless steel dirt screen that prevents particles larger than 2.3 mm from entering. Periodically inspect and clean the screen to ensure unrestricted water flow.
- Vinteropbevaring: If the pump will not be used during freezing temperatures, remove it from the well, drain all water, and store it in a frost-free environment.
- Generel rengøring: Clean the exterior of the pump and control box with a damp klud. Brug ikke skrappe rengøringsmidler eller opløsningsmidler.
- Inspektion: Regularly check the power cable and connections for any signs of damage.
