Commissioning and decommissioning
4.1
Commissioning
All the following work must be carried out in the specified sequence.
1.
Filling the hot water storage tank:
• Fill the heat exchanger for domestic water.
• Fill in buffer storage volume via the filling and draining cock (to be installed on-site between the return connection of the
hot water storage tanks and the pump) until water emerges at the safety overflow of the hot water storage tanks.
• Close the filling & draining cock.
2.
Fully open all FlowGuard valves.
3.
Switch on the Solaris R3 controller.
The initialisation phase begins.
4.
When the initialisation phase is finished (temperature display) fill and vent the Solaris system by simultaneously pressing
both arrow keys (starts the manual operating mode).
The circulation pump and, where installed, the booster pump run. The Solaris system is filled with water, and the air
escapes through the flow pipe into the air space of the hot water storage tank.
5.
Check the entire system for leaky joints (in the building and on the roof). Seal any leaks that occur in a professional manner.
6.
Set the FlowGuard valves (see also Table ):
• On systems without a booster pump, set the flows in accordance with work step (Chapter 3.2 "System design").
Reference values for setting the flow rate, depending on the number of solar panels assigned to the hot water storage tank
WARNING!
The Solaris installation may only be commissioned after all the hydraulic and electrical connections have been
made.
Incorrect commissioning will impair the system's function, and can lead to damage to the entire installation.
Therefore, installation and commissioning should only be carried out by heating technicians trained and
authorised by ROTEX.
CAUTION!
Commissioning under frosty conditions can result in damage to the entire installation.
•
Commissioning with outside temperatures below 0 °C should only be undertaken if a water temperature
of at least 5 °C in the solar circuit can be guaranteed (e. g. by previous heating of the DHW storage tank).
ROTEX recommends not operating the installation in extremely frosty conditions.
If several Solaris hot water storage tanks are connected, the settings should be carried out parallel and step
by step on all hot water storage tanks.
