Page 4: S1 General Information
About these instructions These instructions describe the functioning, installation, commissioning and operation of the SolexMidi TW and SolexMaxi TW transfer stations for charging buffer tanks or domestic hot water tanks. The chapters called [specialist] are intended for specialists only. For other components of the solar installation, such as pumps, collectors, storage tanks or expansion tanks, please observe the instructions of the corresponding manufacturer. -
Page 5: About This Product
1 General Information About this product The station is a premounted group of valves and fittings checked for leakage and used to transfer the heat from the primary (solar circuit) to the secondary circuit (heating circuit or domestic hot water circuit). It contains a preset controller as well as important fittings for the operation of the system: Ball valves in the primary circuit (flow and return) ... -
Page 6: Designated Use
Due to its design the station must be mounted and operated as described in these instructions! Only use PAW accessories with the transfer station. Improper usage excludes any liability claims. Schematic structure... -
Page 7: Safety Instructions
2 Safety instructions 2 Safety instructions The installation and commissioning as well as the connection of electrical components require technical knowledge commensurate with a recognised vocational qualification as a fitter for plumbing, heating and air conditioning technology, or a profession requiring a comparable level of knowledge [specialist]. - Page 8 2 Safety instructions CAUTION Risk of burns! The valves and fittings and the pumps can become heated up to more than 100 °C during operation. The shell must remain closed during operation. CAUTION Personal injury and damage to property due to overpressure! By closing the two ball valves in the primary circuit you isolate the pressure relief valve from the heat exchanger.

4 Commissioning [specialist] Preparations before flushing and filling NOTICE Note regarding the expansion tank To prevent that the dirt particles in the solar thermal system are flushed into the expansion tank, some manufacturers recommend to disconnect the expansion tank from the solar circuit before flushing and filling. -
Page 14: Flushing And Filling The Solar Circuit
4 Commissioning [specialist] Flushing and filling the solar circuit The fill and drain valves required to flush and fill are integrated in the transfer station. Make sure not to wash dirt particles that may be present in the system into the heat exchanger and the expansion tank. - Page 15 4 Commissioning [specialist] Airstop The Airstop with manual vent valve is used to vent the solar installation. To ensure a perfect ventilation of the solar circuit, the flow velocity must be at least 0.3 m/s in the flow line. Pipe diameter [mm] Flow rate at 0.3 m/s ∅...
- Page 16 4 Commissioning [specialist] 1. Switch off the pump in the solar circuit. 2. Disconnect the expansion tank from the solar installation. This avoids the access of dirt particles present in the pipes to the expansion tank. Observe the separate instructions regarding the expansion tank! 3.
- Page 17 4 Commissioning [specialist] 11. Reduce the pressure on the drain valve [g] to the operating pressure. 12. Connect the expansion tank to the solar circuit and set the operating pressure of the solar thermal system by means of the flush and fill station (for the required operating pressure, see instructions of the expansion tank).
- Page 18 4 Commissioning [specialist] 18. Remove the hoses of the flush and fill station and screw the sealing caps onto the fill and drain valves. The sealing caps only serve to protect the valves against dirt. They are not designed to take up high system pressures.
