Evaporator/s obstructed completely
by ice Carry out an additional defrosting cycle. USER
Wrong temperature setting Set the appropriate temperature.
The appliance is affected by draughts or is
exposed to direct or reflected sunlight Remove any draughts and prevent any direct or reflected sunlight.
Insufficient air flow for
cooling to the condenser Remove anything that may affect air flow inside the condens- ing unit (paper sheets, cardboard, grids with an insufficient
number of holes, etc.).
Internal fans at standstill or with fans damage TECHNICAL
ASSISTANCE
Internal ventilation is too high
Thermostat / Electrical base unit
not efficient Replace the electronic control board. If the control unit is set up especially for must R290 refriger-
ant, it must only be replaced with an original replacement
from ISA. Replace the temperature probes only after
checking which of the two is not operating efficiently.
Condenser unit blocked by dust
or dirt in general. Clean the condensing unit thoroughly. The air condenser or MAINTENANCE FREE, in particular heavy
environments (e.g. presence of dust, the presence of exces-
sive moisture, oiled vapours etc..) in order to avoid perfor-
mance loss, needs accurate cleaning.

in the display chamber, the compressor will not start.
Set the suited temperature if the current temperature
is not low enough.
Intervention of the maximum pressure
switch (where present) Check the cause of continuous intervention of the maximum pressure switch, which may be: air condenser blocked, con-
densing fan stopped, ambient
temperature too high, pressure switch defective.
