FAILURE CAUSE SOLUTION
The appli-
ance is not
working
Blown protective fuse Find what triggered the
switch and subsequently replace the fuse.
The master switch is open Close the master switch.
Plug is not inserted Insert the plug.
Power cut If the power cut persists,
transfer the product to a freezer.
The internal
temperature
is not low
enough
Evaporator(s) completely blocked
by ice
Carry out an additional defrosting cycle.
The wrong temperature has been
set on the electronic control board
Set the right temperature.
The equipment is affected by
draughts or is exposed to direct or
refl ected sunlight
Eliminate 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.).
The internal fans have stopped
or their blades are damaged
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 electronic control unit. If set-up for coolant R290, the
control unit must only be replaced with ISA supplied original
spare part. 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
compressor
does not
work or
works only
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 mains voltage at the ends of the power supply
cable is 220V +/- 10%.
The temperature set on the
thermostat is too high
If the set temperature is higher than that of 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
(if any) was
activated at maximum pressure
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.
