Safety regulations, instructions 

and guidelines

The  substructure  as  well  as  its  connections  to  the 

building have to be checked on site according to the local 

circumstances.

The collectors have to be mounted in an angle of at least 

20° to max. 70°.

Recommended heat transfer medium is a mixture of glycol 
and water. The collectors may never be operated or tested 
under pressure with water.

To protect the system of overheating during standstill  and 

accelerated glycole-aging a self-draining system (e.g. STI 

Drain Master or Drain Box) is recommended.

It is absolutely necessary to pay attention, that the back flow 

temperature is never lower than the ambient temperature. If 

necessary, take appropriate action (e.g. increase back flow 

temperature to at least 30°C).

Lightning protection

Note country-specific legislation!

Throughout the installation of metal fastening, a check is 

needed by an authorized qualified electrician.

The  metallic    pipes  of  the  solar  circle  are  connected  via 

a  copper  pipe  of  at  least  16  mm²  with  the  earth  circuit 
connector.

Please  ensure  sufficient  ventilation  for  each  assembly 

method. Do not close the ventilation openings. Especially 

in case of  roof-integrated assembly, the ventilation of the 

collector  is  definitely  necessary.  Appropriate  ventilation 

hoods are available from the supplier. Pay attention to the 

regulations of the ZVDH (Germany), SVDW (Switzerland) 

as well as different local regulations concerning the ventila-

tion. If necessary, consult an expert.

Responsibilites

The constructor of the installation is responsible for the in-

tegration of the installation according to regulations and for 

compliance with the safety regualtions.

The operator of the installation is responsible for an ope-

ration  of  the  installation  according  to  regulations  and  for 

consultation of experts in case of problems.

This instruction is not subjected to the control of a service of modi-

fications. It does not absolve the manufacturer and operator of the 

installation of his responsibilities to install and operate all parts of 

the installation according to utmost professional knowledge. The 

manufacturer of the installation is responsible to observe and keep 

all appropriate regulations and instructions.

Statics

Before  beginning  the  assembly  it  is  vital  to  test  the  roof  or 

substructure on site to sufficient load-carrying capacity. 

Pay  increased  attention  to  the  possible  durability  of  the  screw 

fittings to fasten the collectors as well as to the quality of the sub-

structure.

According to DIN 1055 part 4 and 5 or rather according to the local  

engineer standards it is necessary to check on site the whole col-

lector installation, especially in snowy regions (note: 1 m² powder 

snow ~ 60 kg / 1 m² wet snow ~ 200 kg) as well as in regions with 

high  wind  speed.  Before  starting  the  assembly  all  aspects  that 

may lead to incorrect load of the whole construction have to be 

considered!

Install  the    collectors  the  way  that  backlog  of  snow  (e.g. 

due  to  snow  guards  or  other  obstacles)  is  not  possible.  

In  case  of  correct  assembly  snow  loads  up  to  2  kN/m² 

and  wind  loads  up  to  80  km/h  (inland  up  to  10  meters 

height  of  buildings)  on  the  collectors  are    permissible.

For transport and stocking

 
Never abandon the delivered collectors unprotected at the building 
site. Never lay down the collectors onto a rough surface with over-
hanging pieces like stones, timbers, etc.
Stock  the  collectors  always  upright  leaning  against  a  solid  sur-
face.
The rigidity of the collectors is limited. During transport to the buil-
ding site always ensure a torsion-free transport type. In case of an 
elevated  intermediate  storage  make  sure  that  the  collectors  are 
protected against sliding down.
