1.2 About this manual
This solar pump station is a preinstalled and leak-tested group of fitting for transferring heat from the collector to the store. It contains important fittings and safety devices for the operation of the solar thermal system:
Ball valves in flow and return in combination with check valves to prevent gravity circulation.
Air stopper for manual bleeding of the solar thermal system
Electronic flow rate check for displaying the flow rate
Manometer for displaying the system pressure
Safety valve to prevent inadmissible overpressure
Flushing and filling unit for flushing, filling and emptying the solar thermal system.
1.3 Safety instructions
The installation and commissioning of the solar station as well as the connection of electrical components requires technical knowledge commensurate with a recognized vocational qualification as a fitter for plumbing, heating and air conditioning technology, or a profession requiring a comparable level of knowledge. The following must be observed during installation and commissioning:
The relevant regional and national regulations.
The technical and safety instructions of these instructions.
Warning: risk of scalding
There is danger of steam emission with safety valves. Therefore a discharge pipe must be connected to the safety assembly, please observe the enclosed instructions regarding the safety valve when doing this.
Attention: damage of solar pump station
The group of fittings must be installed with sufficient spacing to the collectors because temperatures in the vicinity of the collectors can be very high. An intermediate vessel may be necessary for installation in the attic.
It is imperative that you make sure the EPDM sealing elements of the solar pump station do not come into contact with substances containing mineral oil. Mineral oil products cause lasting damage to the material, whereby its sealant properties are lost. If necessary, ask the manufacturer whether the solar fluid, fats or installation aids contain mineral oils. We don’t assume liability nor provide warranty for damage to solar station resulting from sealants damaged in this way.
