3 DESCRIPTION OF THE SYSTEM
Our system is a solar hot water heating system that
functions on the principle of natural circulation. The
heat transfer liquid therefore circulates by normal con-
vection.
The system comprises one or more solar collectors and
a jacket type storage tank, located above the collec-
tor/s.
The system does not require any pumps or adjustments.
The system comprises:
− Solar collector/s
− A jacket type solar storage tank
− Cartoon box with: fi ttings, anti-freeze liquid, 1
installation manual and 1 manual with the imag-
es for the installation.
− Mounting brackets
− Water pipes .
4 SAFETY DEVICES
The system is equipped with the following safety de-
vices:
− 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 pressure
in the secondary (DHW) circuit rises above a 10 bar
threshold.
SAFETY MEASURES
• Always use certifi ed installation tools and full protection
devices.
• In case you need to work near electrical wires, turn the
electricity off.
• Always wear protective goggles, protective boots,
gloves and masks in compliance with the respective
safety regulations.
9
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.
9
Safety devices must only be replaced by our Tech-
nical Assistance Service using original spare parts.
9
Over-temperature protection requires an adequate
supply of cold water from the mains.
