Troubles Solutions
Operation
This is a normal situation
caused by the short suction of
water by the internal pressure
of the refrigerator
The refrigerator makes too
much noise even being in
operation for some time.

"Installation"
Even with little frequency of
opening of the door and the
correct distribution of bottles,
the same ones don't reach the
refrigeration temperature
Opening very
frequent door
Distribute the bottles again
avoiding excessive quantities
of bottles

After a period of operation

some noise during the

This is a normal
situation if the
refrigerator was not
used by some time
The refrigerator micro-processed controller is responsible the following functions:
1 COMPRESSOR COMMAND
The controller turns off the compressor when the internal temper ature reaches the adjustment point, fastening it again when over coming
the differential. For example, a controller with a adjustment po int is -3,5° C and a differential of 1 ° C. The compressor will turn off to
-3,5° C the compressor will turn off when defrost is actived too, and still turned off by a non inferior period of 90 secon ds after connected
the unit. This retard has the objective of increasing the useful life of compressor. In event of flaw of sensor the compressor w ill stop
immediately and an alert will be shown in temperature indicator ( consult temperature indicator alerts ).
2 DEFROST
The controller executes automatically a cycle defrost after to b e connected the unit and every 8 hours of
operation. the purpose of cycle defrost when is connected the re frigerator, is to avoid the excessive
accumulation of ice in energy supply flaw, the controller restar t the operation time when being disabled.
For example: supposing that 6 hours of operation have passed ( l acking only 2 hours for next defrost ) and happens
a energy supply flaw.
When losing the controller the registration of lapsed time, imme diately it will execute a defrost cycle, so the user doesn't
need to wait 8 hours for next defrost. The defrost cycle will be concluded when the evaporator reaches the temperature of
+15°C., the internal temperature be up of +30 °C or measured by time, 20 minutes after defrost cycle has conclu ded
(whatever happens first). When the refrigerator is connected and the temperature of evaporator is up +15 °C, the defrost
system will remain disabled. In case defrost sensor failure, an alert will be shown by the temperature indicator (consult
temperature indicator alert)
