Instructions

Before beginning the assembly of the structure, make sure that the place
where the equipment will be assembled has enough structural strength to put
up with the mechanicals loads caused by the equipment's own weight as well
as the wind and / or snow actions.
There is a single mounting structure that serves for flat surface or tilted roof.
The structure has to be level, and in a place that does not receive shadows. You
must also take into consideration that the optimal orientation is South (in
North hemisphere)
In case of mounting on a tilted roof, it must have a minimum inclination of 20º.
Be sure to perform the assembly according to the above schemes. The
tightening of the screws must be done firmly.-The correct fixing of the system
to the roof(tilted or flat) is under the responsability of the techni-cian.
Assembly of all connection elements.
Connect all the described elements in the images, except for the safety valve
and the cap ½". Start always filling up the secondary circuit (consumption)
checking that there are no leaks in the connections carried out on it. Make
sure you have properly installed the tightness of the secondary circuit in
hoses.
Always fill up de secondary circuit (comsumption) before the
primary (solar) in order to avoid the squashing of the tank.
Filling of the primary circuit (solar)
Before filling the primary circuit, you should perform the mixture of water
and antifreeze in an appropriate proportion in order to protect it of the
minimum historical temperature registered in the area where will be the
installation. It is the responsibility of the technician to determine the
amount of antifreeze necessary to protect the installation. The filling must be
done by the superior takes that's the cap ½". This operation must be carried out
with the safety valve uninstalled to favour the air outlet during the filling
process. Once this circuit is completely full and start to flow the liquid by the
superior takes, start installing both the brass cap as safety valve.
Check the correct tightness of all connections made. It is normal that on the
first days of operation there is a small drop through the safety valve of 2 bar, as
this will generate an air chamber at the top of the circuit and it will work as
expansion chamber.
Check the safety valves are connected and positioned so as to avoid any
accumulation of dust, deposits or other similar impurities, as they appear in
the images. Never close or plug the safety valves. Under certain conditions,
safety valves may release steam, so it is necessary to orient them so that no
injuries happened.
As safety element, we recommend to use a thermal discharge valve. In this
way, it will be ensured that the equipment does not exceed temperatures
higher than 90ºC.
