8. Attachment / Before starting the equipment

Installation of a suction line
• Screw a suction hose (plastic hose min. 19 mm (3/4") directly or with a threaded nipple,
approx. 25.4 mm (1"), to the suction line connection on the pump.
• Lay the suction line from the water pick-up point to the pump in a continuously rising
slope. Ensure that the suction line is not laid above the pump height; air bubbles in the
suction line delay and prevent the suction process.
• The suction and pressure lines must be installed in such a way that they do not exert any
mechanical pressure on the pump.
• The suction valve should be located deep enough in the water to prevent the pump from
running dry if the water level drops.
• A leaking suction line will prevent the water from being sucked in due to air ingress.
• Avoid sucking in foreign bodies (sand etc.).
Installation of a pressure line
• The pressure line (should be at least 19 mm (3/4")) must be connected directly or via a
threaded nipple approx. 25.4 mm (1") to the pressure line connection on the pump.
• During the suction process the shut-off devices (spray nozzles, valves etc.) in the deliv-
ery line must be fully opened to allow the air in the suction line to escape freely.
