of the switch, and then re-introduce the new fuse.

The master switch is open

Close the master switch.

The plug is not inserted 

Insert the plug.

Electric black-out

If the black-out should be prolonged, 
transfer the product into an appropriate cold storage container.

The internal 
temperature 
is not low 
enough

Evaporator/s obstructed completely 
by ice

Carry out an additional defrosting cycle.

The wrong temperature has been 
set on the electronic control board

Set the appropriate temperature.

The appliance is affected by 
draughts or is exposed to direct or 
refl ected sunlight

Remove any excessive draughts and prevent any direct or re-
fl ected sunlight.

Insuffi cient cooling air fl ow in the 
air condensing unit

Remove anything that may affect air fl ow inside the condensing 
unit (paper sheets, cardboard, grids with an insuffi cient number 
of holes, etc.).

Internal fans at standstill 
or with fans damage

Contact the 

Technical Assistance

 service

Internal ventilation is too high

Contact the 

Technical Assistance

 service

Low electronic control board ef-
fi ciency

Contact the 

Technical Assistance

 service

Replace the electronic control board. The electronic control board, if 
designed for 

R290

 refrigerant must be replaced only with an origi-

nal provided by 

ISA

.

Replace the temperature probes only after checking which of the 
two is not operating effi ciently.

Air condensing unit blocked by dust 
or debris

Contact the 

Technical Assistance service. 

Clean the condensing unit thoroughly.

Insuffi cient coolant
in the cooling system 

Contact the 

Technical Assistance

 service

Find the cause behind the lower amounts of coolant and eliminate 
it. Top up the coolant. If necessary, empty the system before 
topping up. 

The com-
pressor does 
not start-up 
or operates 
for a few 
moments

No power supply

Check if there is a power cut.
Close the various switches on the power supply line.

The power supply voltage is too 
low

Check that the network voltage of the power supply cable is 220V 
+/- 10%.

The temperature set on the
thermostat is too high

If the set temperature is higher compared to the air in the display 
area, the compressor does not activate itself.
Set a more suitable temperature if the current value is not low 
enough

The pressure switch operated at 
maximum pressure 

(where present)

Contact the 

Technical Assistance service. 

Check the reasons why the pressure switch is operating at 
maximum pressure levels, such as: air condensing unit blocked, 
condensing unit fan stopped, ambient temperature too high, 
pressure switch broken.
