This product complies to the requirements to the european directives and following standards:
2006/95/EC Low Voltage Directive
Reference Standard: EN 60.335.1.
2004/108/EC Electromagnetic Compatibility Directive Reference Standards: EN 50.081.1 / EN 50.082.1 / EN 55.014.

2 Safety instructions and recommendations

2.1 Safety instructions

Any work on the installation must be done by a qualified
professional in compliance with the codes of practice and according to the instructions provided.

2.2 Recommendations

Have the installation regularly serviced to guarantee that it operates correctly over time. It is essential to check the magnesium anode in the DHW tank and the installation and heat transporting fluid pressure every two years.
Never cut the power to the solar control system, even
during extended absences. The control system protects the installation against overheating in summer when it is running.
During extended absences, we recommend lowering the set point temperature in the solar DHW tank to 50°C. When the user is present, the set point must be set to 60°C.
Never drain the installation. Do not replace or add water or
solar fluid to the installation. These actions must be carried out by a qualified technician.
Do not modify the control system parameters unless fully
conversant with them.
