The primary circuit of the solar collectors must be in accordance with all the 
necessary security measures, particularly a safety valve correctly set, an expansion 
tank designed to even take into account the evaporation of liquid contained in the 
collectors and a system of protection against overheating (heat sink or similar), if 
necessary.  
 
The primary circuit of the solar collectors must have at least a thermometer and a 
manometer to permit recording of the temperature and the pressure of the circuit.  
 
Before the final filling of the primary circuit, internal washing with domestic water 
should be carried out to remove any dirt or rests and pressure test should be carried 
out to verify the sealing of all, without exceeding the maximum pressure allowed by 
solar collectors. This is to verify that the connections between solar collectors have 
no leaks. If that is so, the fittings should be tightened, using two keys, so as to avoid 
transmitting force (tortion) to the pipes of the absorbers of the solar collectors.  
 
During the final filling of the solar system with antifreeze fluid it must be verified that 
the circuit is perfectly purged and pressurized. Once this operation is finalized, the air 
vents should be closed.  
 
It should be avoided to carrying out operations such as washing and filling the 
primary circuit while or after the solar collectors are exposed to intense sun.  
 
 
8. Lightning Protection 
National norms and regulations over lightning protection should be closely followed. 
In any case the support(s) of the collectors must be “earthed” with copper wire of 
16mm

2

 to the ground grid of the building. This will serve as lightning protection. 

 This guideline does not release in any way the installer from his responsibility 
against lightning protection requirements. 
 
 
9. Permissible wind and snow load 
Permissible negative pressure for wind load is 1500 Pa     
Permissible positive pressure for snow load is 2000 Pa
