Electrical connection
The electrical connection takes place via an electric safety socket 230 V ~ 50 Hz. Fuse protection
at least 10 Amperes.
The appliance is turned on/off by means of the ON-/OFF-switch. The indicator light of the switch
glows, if the engine is started.
The engine is protected against overloading or blocking by means of a built-in motor protection. In
case of overheating the pump is turned off automatically due to the overheat protection and after
the cooling the pump is automatically started.
Suction line
Connect a suction hose (plastic hose min. 3/4" spiral reinforced) directly or with a thread nipple to
the suction connection (1" internal thread) of the pump.
The suction which is used should have a suction valve. In case the suction valve cannot be
employed a check valve should be installed in the suction line.
Position the suction line from the water withdrawal to the pump on a rising gradient. Avoid by all
means placing the suction line higher than the pump height, air pockets in the suction line slow
down and impede the suction process.
The suction and the pressure line have to be installed in such a way, so that they do not exert any
mechanical pressure on the pump.
The suction valve should lie deeply enough in the water, so that a drop in the water level cannot
lead to the dry running of the pump.
A leaking suction line prevents the suction of water due to air intake.
Avoid sucking in foreign particles (sand etc.) and if necessary install a prefilter.
Pressure line connection
The pressure line (should be at least 3/4") must be connected directly or via a thread nipple to the
pressure line connector (1" internal thread) of the pump.
With the suitable screw joints a 1/2"- pressure hose can be used. Correspondingly the pump
output is reduced due to the small pressure hose.
During the suction process the shut-off devices (valves, spray nozzles) in the pressure line must
be completely open so that the air in the suction line can escape freely.
Commissioning
Position the pump on a stable and flat location with a temperature that does not exceed 40°C.
Place the pump in a horizontal position so that the bearing can function properly; tighten the
pump to the ground.
Install the suction line so that it is ready for use. The suction hose should not be narrower than
the suction connection. If the suction height exceeds 4 m, you must use a suction line with a
larger diameter.
Establish the electrical connection.
Fill in the pump with water at the pressure port.
During the suction process the shut-off devices (valves, spray nozzles) in the pressure line must
be completely open so that the air in the suction line can escape freely.
Depending on the suction height and the air quantity in the suction line, the first suction process
can take approx. 0,5 min - 5 min. For longer suction periods new water should be refilled.
If the pump is removed after its use, do not forget it has to be refilled with water (before you
operate the pump again) before restarting and connecting it again.
