VIII) ELECTRICAL CONNECTIONS 

 

The  electrical  connections  must  be  in  compliance  to  the  regulations  applied  in  the  country  of 
installation  and  must  always  be  realized  by  a  certified  electrician.  Below  is  a  diagram  of  how  the 
power supply is connected to the heating element through the thermostat.  

 

 

IMPORTANT: 

The electrical connections plastic cover on the side of the water tank should be installed 

as  shown  in  the  drawing  above.  The  smaller  hole  is  for  the  overflow  of  any  water  leaking  into  the 
electrics  cavity  and  should  be  placed  at  the  lowest  point  of  the  cover.  The  electrical  cable  hole  is 
larger to accommodate for the diameter of the cable and protective sheath.  

CAUTION

: If you 

DO NOT

 connect the electrical resistance with the electrical panel of your house, you 

need  to  earth  the  anode  with  the  roof’s  slab  or  with  elsewhere  made  of  concrete  or  wood  and 
certainly 

NOT

 with the electrical earthing in order to fulfill the warranty conditions of your solar water 

heater.
