- Page 2 1. Introduction CSE2 SOL W SRS1 T-K twin-line solar pump station contains all components necessary for current and efficient operation. It is designed for operation with one solar consumer (e.g. hot water tank) and for connecting a switched heat source (e.g. a gas boiler). To connect it, the pump station is equi- pped with a special connector with a 4m cable.
- Page 3 Min. values of working pressure** Values of min. working pressure 0.8 bar at 50 °C at the pump suction port depending 1.2 bar at 90 °C on temperature 1.8 bar at 110 °C ** this condition is met for current installations when the initial system pressure is set following the formula (see the Instructions for solar collectors): p = 1,3 + 0,1·h [bar], where h ...

WARNING! IMPORTANT! The safety relief valve, expansion vessel and upper filling valve always remain connected with the solar thermal system, even when the ball valves are shut off! Never try to isolate them from a filled solar thermal system as there is a risk of serious injury and damage to the system! Never close the safety valve discharge piping, it shall remain free for fluid eventually discharged by the safety valve! 5. - Page 6 8.

9. Wilo-Para iPWM2 Pump The Wilo Para 25/7 iPWM2 is a wet running circulation pump. The pump speed is controlled by the PWM signal. When the PWM signal is disconnected, the pump stops running (a pump for solar thermal systems). The operating status and possible faults of the pump are indicated by LEDs directly on the pump. - Page 8 9.2 Technical Data Wilo PARA 25/7 iPWM2 Electric Data Power supply 1 ~ 230 V, 50 Hz Power input (min./max.) 1.8 / 50 W Current (min./max.) 0.02 / 0.43 A Max. speed 4700 rpm Energy Efficiency Index ≤ 0,20 by EN 16 297/3 IP rating IPX4D Motor protection...
- Page 9 10. Filling a Solar Thermal System For filling a solar thermal system, the ball valve above the pump must be closed and the ball valves below the pump and on inlet pipe from the solar collectors open. The ball valves above the pump are operated by means of the enclosed spanner.
- Page 10 11. Solar System Air Venting • During operation of the filling pump, close the lower drain valve and increase the pressure to about 5 bar; • close the upper filling valve and turn off the filling pump, open the ball valve above the pump, do not disconnect the filling pump hoses! •...
