Preparations
Placement
Preventing water damage. Pre-planning prevents accidents!
• Leakage in the pump and hoses may occur through freezing, incorrect installation,
pressure surges, etc. The pump should therefore be placed in a waterproof
environment approved by your insurance company and your insurance policy.
Contact your insurance company if you are unsure.
• Place the pump on a firm, hard surface, well protected from water spray.
Mains connection
• Connect the mains lead to an RCD protected earthed socket for personal safety.
Suction hose connection
• Connect a suction hose with a 25 mm (1
″
) minimum diameter to
the vacuum port (R25) (5).
• The suction hose should be fitted with a foot valve/non-return valve.
• Place the suction hose so that it slopes upwards from the water to the pump inlet.
• The suction hose must always be on a lower level than the inlet to the pump.
Airpockets in the hose could disrupt the pump’s operation.
• Hoses or pipes must not be connected in such a way as to exert any pulling strain
or tensile stress on the pump unit.
• Fit the foot valve to the end of the suction hose (pipe).
• The foot valve should be anchored to the bottom so that the pump does not run
dry if the water level drops.
• The suction hose assembly must be air-tight to prevent air from being sucked into
the pump.
• A filter should be fitted to the suction side to prevent sand, mud, etc from being
sucked into the pump.
Pressure connection
• Connect a 19 mm (3/4
″
) spiral-reinforced high-pressure hose to the outlet hose
connection (R25, 1
″
) (7). Smaller hoses reduce capacity.
