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
 Flow rate check for displaying the flow rate
 Manometer for displaying the system pressure
 Safety valve to prevent inadmissible overpressure
 Flushing and filling connector for flushing, filling and emptying the solar thermal
system.
