The
NS-SOL
system is a solar hot water heating system that functions on the principle of natural circulation. The heat
transfer liquid therefore circulates by normal convection.
The system comprises one or more solar collectors and a jacket type storage cylinder, located above the collector/s.
The system does not require any pumps or adjustments.
18 PUTTING INTO SERVICE
The system must be put into service for the first time by
B
’s Technical Assistance Centre. After this it will continue to
function automatically.
19 MAINTENANCE
If the system is easily accessible, regularly check the cleanliness of the glass panel/s of the collector/s. If necessary,
clean the glass, but only when it is cold, preferably in the early morning. If access is difficult, contact your local Technical
Assistance Centre.
Once a year, check the condition of the insulation around the pipes.
If the system is not going to be used for an extended period of time, contact your local Technical Assistance Centre to
have it made safe.
b
The solar water heating system must be serviced periodically by
B
’s Technical Assistance Centre or by a qual-
ified heating engineer.
b
The system must be serviced at least once a year.
b
If no domestic hot water is drawn off from the system, the safety valves of the domestic hot water and solar collector
circuits may open to discharge pressure and ensure correct functioning.
b
These safety valves present a risk of burns or scalding. If a pressure in excess of 2.5 bar builds up in the solar col-
lector circuit, the safety valve opens.
b
Check the condition of the magnesium anode regularly as it provides protection against corrosion.
b
The system can reach very high temperatures (>150°C) under normal operating conditions. Take the greatest care
to avoid burns or scalding.
b
In the event of any malfunctioning or failure, and to have parts replaced, contact
B
’s Technical Assistance
Centre.
