BEFORE STARTING THE MACHINE  

 

The  boiler  circuit  breaker  QFE10  (and  QFE11)  has  to  be  open  (position  OFF).  Before 
reactivating it, check, after having switched on the machine that the boiler is full of water by 
making sure that water is coming out of the rinsing nozzles. 

 

Make  sure  that  all  3ph  motors  turn  in  the  right  direction  (heat  pump  compressor  end 
recirculation pump, dryer fan).
