Page 4: General Information
About these instructions These instructions describe the function, installation, commissioning and operation of the transfer stations CIRCOtransfer 30 E and CIRCOtransfer 50 E. The chapters called [specialist] are intended for specialists only. For other components of the installation, such as pumps, controllers or the distribution manifold, see the manufacturers' instructions. -
Page 5: About This Product
1 General information About this product The station is a premounted group of fittings checked for leakage and used to transfer the heat from the primary or solar circuit to the secondary or storage tank circuit. It contains important fittings and safety devices for the operation of the installation: Ball valves with integrated thermometers in the storage tank circuit ... -
Page 6: Designated Use
Only use original accessories with the transfer station. Improper usage excludes any liability claims. Schematic structure CIRCOtransfer 30 E/50 E Scope of delivery When the sun shines, the collectors can become very hot. The solar fluid in the circuit can heat up to more than 100 °C. -
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 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. A rise in temperature in the storage tank will cause high pressures and could result in personal injury or damage to property! ...

Page 9: Assembly And Installation [Specialist]
3 Assembly and installation [specialist] 3 Assembly and installation [specialist] The location of installation must be dry, load-carrying, frost-proof and protected against ultraviolet radiation. Furthermore, the access to the control and safety equipment must be guaranteed at all time during operation! The discharge line of the safety equipment should be guided into a heat-resistant container with corresponding size. - Page 10 Flow to the buffer tank ④ Return from the buffer tank All screw connections of the CIRCOtransfer 30 E have ¾" internal threads, all screw connections of the CIRCOtransfer 50 E have 1" internal threads. 8.

The fittings can heat up to more than 100 °C. Therefore, do not clean or fill the system with the collectors heated (intense sunshine). -
Page 13: Preparations Before Flushing And Filling
4 Commissioning [specialist] Preparations before flushing and filling CAUTION 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 (air-scoop with plug for manual venting) serves to bleed the solar installation. To ensure perfect deaeration 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. 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! 2. The return ball valve [b] must be closed (90°...
- Page 17 4 Commissioning [specialist] 10. Reduce the pressure at the drain valve [h] to the operating pressure, if necessary. 11. 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 the instructions of the expansion tank).
- Page 18 4 Commissioning [specialist] 17. 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.
