Anleitung Zusammenfassung
SL-PS Installation & Operation Manual 3 Technology, installation and commissioning Clamp ring screw connections ¦ Cut the copper pipe to length and deburr. ¦ First, slide the clamp ring nut over the pipe, then slide the clamp ring. ¦ Insert the prepared pipe into the screw connection until its stop is reached. ¦ Tighten clamp ring nut by hand. ¦ Use open-ended wrench to tighten clamp ring screw connection (approx. 33 Ft lb), re-tighten if necessary. ¦ When tightening the clamp ring screw connection, use two wrenches–using one wrench to prevent the pumping station from turning. Flat seal screw connections ¦ All pre-fitted solar station screw connections are firmly tightened in the factory so that they do not need to be retightened. Torque levels when tightening flat seal screw connections using AFM 34 flat seals, s = 2mm. – 3/4" screw connection 26 Ft. lb – 1" screw connection 40 Ft. lb – 1 1/4" screw connection 66 Ft. lb – 1 1/2" screw connection 96 Ft. lb Operation, multi-function ball valve and check valve ¦ The forward flow ball valve must be open for filling, flushing and bleeding solar systems with a filling and flushing pump. The return ball valve should be closed. ¦ Both flow checks should be opened in order to drain the solar system (thermometer handles in 45° position). ¦ The two mult-function ball valves must be fully open in order to operate the solar system (turn the red and blue thermometer handles counter-clockwise until the stop is reached).

The mixing ratio should be adapted to local conditions. ¦ Never flush or pressure test the complete solar system with just water. Flushing the system with water only can cause a freezing hazard. Filling, flushing and bleeding ¦ There is one fill valve with hose connection for filling, flushing and draining the solar system on both the safety group and sensor measurement section. ¦ Connect the pressure hose (forward flow) to the safety group’s filling connection under the pressure gauge and open fill/flush valve. ¦ Connect the flushing hose (return) to the flushing connection on the sensor measuring section and open fill/flush valve. ¦ Refer to “Technology, installation and commissioning: Operation, multi-function ball valve and check valve” on page 6. ¦ Open the supply ball valve (by turning the red thermometer handle counter-clockwise until it stops). ¦ Close return ball valve (by turning the blue thermometer handle clockwise, until it stops). ¦ If necessary, the supply and return check valve can be opened by moving the thermometer handles to the 45° position. ¦ Put sufficient solar liquid in the tank of a filling and flushing pump (not supplied). The mixing ratio should be adapted to local conditions in terms of freeze protection. ¦ Fill the solar system via the filling and flushing pump and then flush the solar circuit for at least 15 min. to purge all of the air out of the circuit. ¦ Close the fill/flush valve (return) with the filling and flushing pump running and increase the system pressure to 60 psi. The system pressure can be read at the pressure gauge. ¦ Close the fill/flush valve (forward flow) and switch off the filling and flushing pump. ¦ Open return ball valve (by turning the blue thermometer handle 90° counter-clockwise until it stops). ¦ The solar system features an air separator. Open the bleeder valve until the solar liquid exits free of air bubbles. ¦ Only if collector bleeder is installed: Bleed the system on the collector until the solar liquid exits free of bubbles. ¦ If necessary, increase the test pressure again to 60 psi and check the system for leaks. If the pressure gauge shows the pressure dropping substantially, you have a leak in the system. ¦ Set the operating pressure to 60 psi as prescribed by the system manufacturer ¦ Start up the circulation pump at maximum speed and allow liquid to circulate for at least 15 min. ¦ Remove the filling station hoses and screw the caps on the flushing and filling valves. ¦ Check the system again for leaks. Use the red and blue thermometer handles to fully open the forward flow and return ball val...
