The activation of the corresponding function is delayed by a timer, awaiting an external signal or disabled by
another procedure that is already in progress. e.g. if is a continuous cycle in progress and a defrost is called,
the latter will remain pending until the end of the continuous cycle, and the corresponding LED (defrost) will
flash.
E0 steady or flashing
control probe error:

probe not working: the probe signal is interrupted or short-circuited;

probe not compatible with the instrument;
The alarm signal E0 is steady if it is the only active alarm (the temperature value is not displayed), while it
flashes if other alarms are active or the second probe is displayed.
E1 flashing
evaporator probe or food conservation probe error:

probe not working, the probe signal is interrupted or short-circuited;

probe not compatible with the instrument;
E2 flashing
condenser probe or food conservation probe error:

probe not working, the probe signal is interrupted or short-circuited;

probe not compatible with the instrument;
IA flashing
immediate or delayed alarm from multifunction digital input:

check the multifunction input and parameters A4 and A7.
dOr flashing
open door alarm:

check the multifunction input and parameters A4 and A7.
LO flashing
low temperature alarm. The probe has measured a temperature lower than the set point by a value that ex-
ceeds parameter AL:

check parameters AL, Ad and A0.
The alarm is automatically reset when the temperature returns within the set limits (see parameter AL).
HI flashing
high temperature alarm. The probe has measured a temperature higher than the set point by a value that
exceeds parameter AH.

PERIODICAL MAINTENANCE
1. The appliance, when equipped with automatic defrosting programmer, should be switched off
and cleaned (see “Cleaning” chapter) at least once a month. The accumulation of ice in the evapora-
tor reduces the performance and makes the energy costs rise. Never remove the ice from the
evaporator with metal objects such as knifes or cutting objects. When the evaporator has ice
the ideal is to let it defrost naturally of the evaporator.
Water resulting from daily defrosting is collected in a plastic recipient that must be emptied, whenever
necessary. In some models this procedure is not necessary since the water is re-evaporated in an ap-
propriate place. Special attention must be taken when a defrosting is made after ice is created in
the evaporator, as the recipient for the condensed water may not have sufficient capacity and
overflow.
2. Before any maintenance or cleaning operation the appliance must be unplugged in order to guar-
antee, that it is not connected to electric power. The plug must be removed from the socket in order
to insure that there is no electrical current of any type. Then remove all the products that are inside the
cabinet and place them in a cold room or an adequate conservation place.
Whenever necessary to remove any protection or isolation all the procedures for this must be correctly
followed. Never restart functioning without making sure that all the removed elements have been dul-
ly fitted on the appliance.
CLEANING
Internal and external cleaning must be done periodically with a soft cloth and warm water with neutral soap (5% of
the water volume) without chlorine.
In this chapter it is very important that the drainage hole of the condensed water is perfectly clear.
“Dry carefully all the rests of water with the help of a sponge.”
On the glass parts use appropriated liquid to clean them.
Condenser cleaning should be made periodically or, whenever it shows impurities or filth that may hinder or block
free circulation of air.
The removal of impurities or filth must be done using a brush of soft hair (never use a metal brush), a vacuum cleaner
or with air pressure flow. (View Fig2/3)
