Page 2: Main Features
1. Introduction CSE SOL W SRS1 T Solar Pump Station is fitted with a solar pump of the latest generation that permits smooth flow control through PWM signal and sends information on the actual flow rate to the controller that shows the value on its display. The complicated setting of the right flow rate is not needed, the Pump Station keeps adjusting it automatically, depending on the actual solar radiation. - Page 3 3.

Page 5: Non-Return Valve
4.1 Non-return Valve The non-return valve prevents the tank from being cooled down by gravity circulation during periods of no sunshine. It is located between the ball valves so it can be removed and cleaned without the need to drain solar fluid from the entire solar circuit. When the red mark is on the left-hand side, the non-return valve is set to normal operation position. -
