Page 16: Flowsensor (Optional)
EKSFLP12A is between 0 and 12 l/min (flow volume) and 0 to 120 °C (feed temperature). The measured values are shown on the control unit EKSR3PA display. The control system EKSR3PA automatically sets the appropriate flow rate when the system is in operation by regulating the speed of the solar panel circulation pump. -
Page 17: Start-Up And Taking Out Of Service
The solar system cannot be started until all hydraulic and electrical connections have been completed. An incorrect start-up will adversely affect the function and may damage the complete system. Installation and start-up must therefore must conducted by DAIKIN-authorised and trained heating experts. 4.1.1 Filling solar panel circuit CAUTION! Danger of scalding by hot solar fluid and escaping steam. - Page 18 – If necessary, correct the system pressure by adding solar fluid (see working step 4 onwards). 15. Separate the filling/flushing pump with hoses from the pump unit EKSRDS1A. 16. Open the blocking of the flow meter completely (slot vertical).
