BSL 150...400 BESL 200...400 2. Safety instructions and recommendations

WARNING

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.

WARNING

Do not modify the control system parameters unless fully conversant with them.

During extended absences, we recommend lowering the set point temperature in the solar DHW calorifier to 45°C. When the user is present, the set point must be set to 60°C.

4.3 Setting the DHW calorifier outlet temperature

4.3.1. Programming and setting the electrical

back-up

The temperature of the volume of water heated by the electrical resistor is set by the installer on commissioning of the installation according to the size of the home. Using the solar control system, it is possible to adjust the volume of water heated to 40 °C by the resistor in two ways:

4 Force the continuous heating of the resistor for significant

unforeseen needs. ¼See chapter: "Force back-up", page 14.

4 Select winter mode w (2 hours maximum according to the volume

of the domestic hot water required at 40 °C) to compensate for the lack of sun in winter. If necessary, the period scheduled outside of the off-peak hours is set between 16:00 and 18:00, i.e at the end of the day when the solar contribution is reduced and just before the drawing off period.

CAUTION

4 Maintenance operations must be done by a qualified

engineer.

4 Only original spare parts must be used.

5.2 Safety valve or safety unit

The safety valve or unit on the domestic cold water inlet must be operated at least once a month to ensure proper operating and to prevent from any overpressure which may that may damage the domestic hot water calorifier.

5.3 Cleaning the casing material

Clean the outside of appliances using a damp cloth and a mild detergent.

5.4 Checking the magnesium anode

The magnesium anode must be checked at least every 2 years. After the first check, determine the frequency of future checks on the basis of anode wear.
