INSTALLATION and OPERATION MANUAL 

Risk of injury, burn upon installation and maintenance of solar collectors: 

-   On contact with broken glass/vacuum tube 
-   On contact with collector in function because of its high temperature. 
We recommend the use of protective equipment, gloves, eyewear (goggles), and clothing. 
Installation  and  maintenance  of  collectors  must  be  carried  out  in  the  early  morning  hours. 
When  the  collector  is  still  cold  you  can  cover  it  with  tarpaulin  to  avoid  its  heating  by  direct 
sunlight. 

 



FIRE HAZARD 

through contact of accumulated waste (dry leaves, plastic bags, paper) with the 

hot  parts  of  the  collectors.  We  recommend  the  regular  inspection  and  cleaning  of  collector 
installation sites.

 

 



DANGER  of  slipping,  fall. 

In  most  cases,  collectors  are  installed  in  hardly  accessible  and 

dangerous  places.  We  recommend  that  installation  and  service  maintenance  be  carried  out 
by authorized service technicians observing all safety measures.

Structural changes to collector by user can cause damage to equipment or injury. 

 

 
 
Safety rules for user operation: 
 

- The solar collector can be used to produce hot water and support the heating system only in the manner 
described in this manual.
