9Installation
Installation location
•The product should be installed in a protected place.
•An installation location should be chosen that is not exposed to humidity, water,
vapours, alkalis, acids or excessive ambient temperatures.
•The assembly area must be level and free of deformation.
•The mounting surface should be free of vibrations and shocks.
•Consider the installation situation when installing the pump.
•The pump housing must be mounted vertically.
1.1.2 Injection points
At “injection points”, the dosed medium is introduced into a pipe containing liquid.
Fig. 4: Position of injection points
Most injection points are fitted in the top of the pipe (1).
If the medium has to be introduced bubble-free, the injection point is installed on the underside
of the pipe (2).
Important information
If injection points are used, it is important to ensure that only small pressure
losses occur at the injection points.
