Page 6: Installation
Installation Description Solar-Divicon-HX is a premounted group of fittings and components used to transfer the heat from the primary or solar loop to the secondary or storage tank loop. The primary and secondary loop are separated with a generously sized stainless-steel double wall heat exchanger with visable leak detection. -

Installation Primary and secondary loop The primary (solar) loop comprises: a– ball valve with integrated temperature gauge and check valve, solar supply b– ball valve with integrated temperature gauge and check valve, solar return c– pressure relief valve - 87 psig d–... -
Page 8: Mounting The Solar-Divicon-Hx
CAUTION The mounting location must be able to carry the full weight of the Solar-Divicon-HX. Take into account the full weight of the unit. Damage or injury could occur if not mounted securely. The discharge line of the pressure relief valve must lead into a heat-resistant collecting tank with corresponding size. -

Install in an immersion sensor well, if possible. Solar return line sensor (TPRI) to S4. This sensor is pre-installed in the Solar-Divicon-HX. 2. Tighten all union nuts and screw connections. The assembly of the heat transfer station is now completed and you can put the station into operation. -
Page 12: Start-Up
Start-up Safety Observe the following safety instructions regarding the startup of the station: WARNING The valves and fittings can heat to temperatures of more than 212° F (100° C) due to the solar fluid. Therefore, do not flush or fill the system with the collectors heated (intense sunshine). -
Page 13: Flushing And Filling The Storage Tank Loop
Start-up Flushing and filling the storage tank loop The storage tank loop is filled with potable water by means of the valves and fittings of the tank. To avoid that dirt particles are washed into the heat exchanger, close the ball valves of the station and wash the dirt particles and scale residues out of the tank. -
Page 14: Flushing The Heat Exchanger
Start-up Flushing the heat exchanger 1. Disconnect the expansion tank from the solar system and temporarily plug expansion tank pipe connection. This avoids that the dirt particles in the pipes are washed into the expansion tank. 2. Put the check valve temporarily out of operation by turning the solar supply ball valve (a) to position 45°... -

Start-up Flushing the heat exchanger (continued) 13. Close the fill and drain valves (d) (c). CORRECT 14. Put the check valves into operating position by turning the ball valves (a) (b) to position 0° (see page 10). 15. Connect the controller to the power supply. Set the solar circuit pump in the manual mode to ON. -
Page 16: Setting The Flow Rates
Start-up Setting the flow rates 1. Switch on the pumps at the controller in manual mode. [ Main menu \ Manual operation \ All relays: ON ] 2. Set the desired speed level (I to III) of the solar pump to obtain the required flow rate. -
Page 17: Service
Service Draining the solar circuit WARNING The escaping medium may be very hot. Place the collecting container so that anyone standing nearby are not in danger of scalding when the solar system is being emptied. 1. Disconnect power supply to the controller and make sure that an accidental restart is not possible. -
