Page 10: Filling Of The Solbox
Filling of the SolBox General Now fill the system with a suitable glycol-water mixture via the filling unit on the SolBox using a filling station. First determine the filling quantity using the table on page 22. Filling quantity = collector content + content pipes + content heat exchanger + content SolBox... -
Page 11: Initial Operation Of The Solbox
Initial operation of the SolBox Step 1: Filling of the installation Now connect a hose, which pumps the glycol- water mixture from the filling station into the system, to the connection (9). The ball valve at connection (9) is opened - see figure 4 // 10. - Page 12 Initial operation of the SolBox Step 2: Venting the system Now partially empty the system to obtain the necessary air volume in the system. Now connect a hose to the breather unit (3) - see figure 1. The hose leads back into the container of the filling station.

- Page 14 Initial operation of the SolBox Step 4: Enhancement of the pressure To prevent a negative pressure within the system it is recommended to run the system with approx. 0.5 bar pressure (above system pressure from static height). Option I - Enhancement of the pressure with compressor - Connect a compressor with the venting unit (3) and open the ball valve - see illustration 1.
- Page 15 Initial operation of the SolBox Option II - Enhancement of the pressure through additional draining and filling For that, first determine the installation volume by the overview below. installation volume = filling vol. - draining vol. - In dependency to the installation volume now a defined volume is released from the system - see table 2.

Page 24: Initial Operation
Initial operation After the installation of the system components, the filling of the system with fluid, the venting, and the adjusting of the installation pressure, the installation is prepared for initial operation. For initial operation use the factory-adjuted solar controller. Please take further information for the process of initial operation from the attached manual of the controller. -
