damaged,  it  should  be  replaced  by  a  cable  of  special  assembly  to  be  furnished  by  the 
manufacturer  or  post-sale  service.  Such  replacement  should  be  performed  by  qualified 
technical service only. 
The machine should be places in such a way as to allow a minimum space between the back 
and the wall to allow an easy access and without risks to the cable jack. 
Safeguard the base of the jack. 
It  is  advisable  to  install  a  power  switch  and  the  appropriate  electrical  safety  devices  in 
accordance with local and/or national regulations in each case. 
 
 
 

 
 
START-UP 
Previous Checkup  

a)  Is the machine leveled?  
b)  Voltage and frequency are the same as those on the nameplate? 
c)  Are the discharges connected and operating?  
** If air condensed:  Is the air circulation and its temperature appropriate?  

** Is water pressure appropriate?  

 

 
 

 

NOTE:

 In case input water pressure is higher that 0,6 MPa (6 Bar) install a pressure reducer. 

THE FAUCETCONNECTION PRESSURE SHOULD NEVER BE REDUCED. 

 
START-UP 

Once  the  installation  instructions  are  followed  (ventilation,  site  conditions,  temperatures, 

water quality, etc.), proceed as follows: 

1)  Connect to drinking water network.

 

Open the water inlet. Verify the existence of leakages.  

2)  Open the door and remove the protection elements that are inserted on the curtain. 
3)  Connect the machine to the electrical network.  
4)  Verify that there are no vibrations or frictions on the elements. 
5)  Verify that the curtain moves freely. 
6)  The machine  has  a  timer  governing  startup,  allowing  for  water  to  be  recharged  for  the 

production cycle 

7)  Verify  that  the  nozzles  send  the  water  to  the  evaporator  on  the  right  direction  (even 

spread).  

8)  Check the cubes after two cycles; they should be uniform in shape. If they do not come 

out correctly, or the unit does not make ice, contact an authorized service technician. 

9)  The unit produces ice until the bin is full, using a stop sensor. When the ice is removed 

from the bin, the unit will once again produce ice.
