3.1 Uitpak en inspeksie

Carefully remove the unit from its packaging. Inspect for any visible damage that may have occurred during transit. Report any damage to your supplier immediately.

3.2 Plasing

Install the pump on a firm, level, and stable surface capable of supporting its weight when full of fluid. Ensure the location is dry, well-ventilated, and protected from extreme temperatures, direct sunlight, and frost. Allow sufficient space around the unit for ventilation and future maintenance.

3.3 Loodgieterverbindings

Connect the suction and discharge pipes to the pump's inlet and outlet ports. Use appropriate fittings and sealants to ensure leak-free connections. Avoid putting strain on the pump's ports by supporting the piping independently. Ensure the suction line is as short and straight as possible and free from air pockets.

Before initial startup, the pump must be primed. Remove the priming plug (if present) or fill the pump casing through the discharge port until the pump body is completely filled with the liquid to be pumped. Replace the plug securely. This step is critical to prevent dry running and damage to the pump.
