• Installation outside a building (outdoor installation):
• Install the pump in a shaft (i.e. light well, annular shaft) with cover or in a
cupboard/housing as weather protection.
• Avoid exposure of the pump to direct sunlight.
• The pump requires protection so that the condensate drain grooves are not
blocked. (fig. 5).
• Protect the pump against rain. Dripping water from above is permitted,
provided the electrical connection is established in accordance with the
installation and operating instructions and the terminal box is closed properly
CAUTION! Risk of damage to property!
Ensure sufficient ventilation/heating if the ambient temperature exceeds/
falls below the permitted limit values.
• Carry out all welding and soldering work prior to the installation of the pump.
CAUTION! Possible damage of the pump!
Dirt and solder drops in the pump body can affect the pump operation.
• It is recommended that any welding and soldering work be done before
installing the pump.
• Thoroughly flush the system prior to installing and operating the pump.
• Foreign material in the system resulting from construction may damage the
pump and is not warrantable.
• The pump must be installed in an easily accessible position to facilitate
inspection or replacement.
• The pump should never be located at the lowest point of the piping system,
where dirt and sediment collect. Nor should it be located at the highest point of
the piping system, where air accumulates. Please ensure at least a minimum of
three pipe diameters of straight on the suction side of the pump.
• It is recommended that isolation valves be installed on the suction and
discharge side of the pump.
This will save having to drain and refill the system if the pump / pump head
needs exchange-service. The valves are to be installed so that any water that
escape cannot drip onto the pump motor or terminal box.
• An arrow on the pump housing indicates the direction of water flow (fig.1, pos.2).
• Install the pump in an easily accessible place, so that subsequent servicing work
can easily be carried out.
Installation is to be carried out such that dripping water cannot drip onto the
pump motor or control module.
• Pump must be installed with the shaft in the horizontal position in such a way
that it is not stressed by the pipework. (Installation positions in fig. 2). When
installing in confined spaces, for example in compact distributors, the control
module can be placed in a vertical position by rotating the motor, see
chapter 9.1.
