7. Only if the water in the Solaris Sanicube does not reach the approximate previous filling level:
• Switch on the Solaris R3 control unit again (initialising phase starts).
• When the initialising phase is complete (temperature display), you can start the manual operating mode by simultaneously
pressing both arrow keys.
• Note the time it takes for the system to be filled completely. The maximum filling level is reached, when no sound of
escaping air can be heard and a stable flow value is indicated (use the arrow keys to select the measuring point "Flow").
• Set the evaluated filling time, plus 20 seconds, as parameter "Time P2" (see Section 5.3.6).
8. Switch the Solaris R3 control unit back to automatic operation either by simultaneously pressing both arrow keys or by
switching the unit off/on. The system is now ready for operation.
9. Only if the RPS3 control unit is connected to two Solaris Sanicubes via a common return flow pipe (storage tank extension
set CON SX):
– The measured common flow in the Solaris feed must be distributed evenly to both Solaris Sanicubes. For an even
distribution, we recommend fitting a FlowGuard for each storage tank.
10. Instruct the user, fill out the acceptance report and send it to the address indicated on the rear cover of this manual.
Within a few minutes, the level indicator in the Solaris Sanicube must show a level that is slightly lower than
before. The reason for this is the presence of a small amount of water remaining in the lower pipes of the solar
panels. This amount of water represents no risk at subzero temperatures, as the empty solar panels provide
sufficient volume for expansion.
The final valve setting can only be determined on a sunny day during normal operation (only one pump)
according to the temperature differences that are reached. With good solar radiation, the solar panel
temperature should settle at a value that is about 10 to 15°C above the return flow temperature.
If a calorimeter has been installed in the system, the flow can be adjusted according to the calorimeter display.
During normal operation (circulation pump on/booster pump off) the value per solar panel should be about 90 to
120 l/h (1.5 to 2.0 l/min).
