When tightening threaded connections, please do not apply excessive force which may cause damage.
When laying the connection pipes, you should make sure that the pump is not exposed to any form of weight,
vibration or tension. Moreover, the connection lines must not contain any kinks or an adverse slope.
5.2.
Installation of the pressure line
The pressure line will convey the liquid from the pump to the point of withdrawal. To avoid friction losses, please
use a possibly large pressure line - ideally, its diameter should match that of the pump outlet.
To facilitate installation, the scope of delivery includes a multi-dimensional connection port (10) offering the
following connection options: male thread connector 41.91 mm (1 ¼ "), hose connector with 25 and 32 mm
internal diameter.
When using the male thread connector 41.91 mm (1 ¼ "), the multi-dimensional connection port is to be used
without modification. If you are using the hose connector with 25 mm or 32 mm internal diameter, those parts of
the multi-dimensional connection port that are no longer needed are to be removed at the (a or b) cutting points
provided. To remove the unnecessary parts, please use a household saw.
If you actually have to proceed to this adaptation, then please do it before you attach the multi-dimensional
connection port to the check valve which is mounted to the pressure port of the pump.
If the check valve was removed, it has to be refitted for the installation of the pressure line and the operation of
the pump. The check valve consists of two parts - one screw thread containing the actual removable valve with a
snap closure. To install the check valve, please start by placing the valve with the snap closure loosely on top of
the pressure port of the pump. The "TOP" inscription is found on top of the snap closure, which must be able of
being opened upwards - i.e. towards the pressure line. Subsequently, please fasten the screw thread to the
pressure port of the pump. When doing so, please note that the inner face of the screw thread is subdivided. The
end with the longer thread is to be screwed to the pressure port. This screwed connection will fasten down the
valve with the snap closure which had initially only been loosely positioned.
5.3.
Stationary installation
If the unit is used in a stationary installation, rigid pipes have proven to be the ideal choice for the pressure lines.
With this type of installation, the pressure line should be equipped with a check valve immediately downstream
the pump outlet to prevent liquid flowing back into the pump after it has cut out. The standard scope of delivery of
the INTEGRA series comes with such a check valve which is already pre-mounted to the pressure port. To
facilitate maintenance work, we also recommend the installation of a stop cock valve downstream of the pump
and check valve. This arrangement is beneficial in that closing the stop cock will prevent the pressure line from
running dry after the disassembly of the pump.
5.4.
How to position the pump
When positioning the pump, please make sure that the max. submersion depth indicated in the technical data will
not be exceeded. Likewise, please make sure that the minimum self-priming level is not fallen short of. If
everything is properly set, the water level may decrease down to the minimum suction level once the pump is
operating.
Please position the pump on solid ground. Avoid placing it on lose stones or sand. When positioning the pump,
please do make sure that the pump cannot tip over or sink into the ground with its intake openings. The
penetration of sand, mud or comparable matters is to be avoided.
To position, lift up or carry the pump, please use only the carrying handle. If required for lowering or raising the
pump, you may connect a suitable lowering rope to the carrying handle. In no case must the pressure hose, the
mains cable or the cable of the floating switch be used to position, to lift up or to carry the pump.
6.
Electrical connection
The unit is equipped with a mains connection cable and a mains plug. It must only be replaced by qualified staff to
avoid any danger. Please do not use the mains connection cable to carry the pump, and do not use this cable to
pull off the plug from the socket, either. Protect the mains connection cable and mains plug from heat, oil or sharp
edges.
The values stated in the technical details have to correspond to the mains voltage. The person
responsible for the installation has to make sure that the electrical connection is earthed in
compliance with the applicable standards.
The electrical connection has to be equipped with a highly sensitive residual current circuit-
breaker (FI switch):
If extension cables are used, their cross-section must not be smaller than that of rubber-
sheathed cables of the H05RN-F (3 x 1,0 mm²) short code. The mains socket and the plug-
and-socket elements have to be in splashwater-proof design.
7.
Putting into operation
Nobody must be in the water while the pump is running.
