GENERAL
3 DESCRIPTION OF THE SYSTEM
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 convec-
tion.
The system comprises one or more solar collectors and
a jacket type storage cylinder, located above the collec-
tor/s.
The system does not require any pumps or adjustments.
Order the mounting frame kit separately to suit the type of
roof involved: flat or sloping.
A supplementary heating element is also available for use
if needed.
The system comprises:
- Solar collector/s
- A jacket type solar storage cylinder
- A box of water fittings
- Anti-freeze liquid
4 SAFETY DEVICES
The system is equipped with the following safety devices:
- A primary circuit safety valve that opens if pressure
in the primary (solar collector) circuit rises above a
2.5 bar threshold.
- A secondary circuit safety valve that opens if pres-
sure in the secondary (DHW) circuit rises above a
10 bar threshold.
b
Water may come out of the primary and secondary
circuit safety valves as a result of variations in tem-
perature and pressure during the course of the day.
Ensure that proper drainage is provided. For the
same reason, avoid standing near the safety valves
during the day.
b
Safety devices must only be replaced by
B
's
Technical Assistance Service using original spare
parts.
b
Over-temperature protection requires an adequate
supply of cold water from the mains.
