4. Applications

The Solar Station is designed to pump clean, thin, non-aggressive and non-explosive liquids, not
containing solid particles, fibres or mineral oil. It is recommended to use a water & glycol solution
(maximum 50% glycol).
The Solar Station is for use in the collector circuit of solar thermal systems in compliance with the
technical data specified in these instructions. This Solar Station comes equipped with safety valve to
prevent over pressure within the system.
In heating systems, the pumped liquid should meet the requirement of accepted standard on water
quality in heating systems.
Warning
The pump must not be used for the transfer of flammable liquids such as diesel oil, petrol or
similar liquids.
The maximum operating system pressure is 1.0 MPa (10 bar)
