1.Safety precautions
Please read the following instructions before servicing your refrigerator.
1)Check the refrigerator for current leakage.
2)To prevent electronic shock, unplug before servicing.
3)Always check line voltage and amperage.
4)If you use any kind of appliance, check regular current. voltage and capacity.
5)Don’t touch metal products in the freezer with wet hands, this may cause frostbite.
6)Prevent water from following onto electric elements in the mechanical parts.
7)When tilting the refrigerator, especially the thin plates(ex. Glass shelf or books).
8)When servicing the evaporator, wear cotton gloves. This is to prevent injuries from the sharp
evaporator fins.
9)Leave the disassembly of the refrigerating cycle to a specialized service center. The gas inside
the circuit may pollute the environment.
10)Close the top door before opening the bottom door, Otherwise, you might hit your might hit
your head when you stand up.

6.Maintenance service and Troubleshooting.
DEFECT EFFECT CAUSE REMEDY
Group
partially or
completely
out of
refrigerant
charge
Evaporator dose not frost even though
motor-compressor runs continually.
An empty refrigerant system indicates
a leakage of R600a.this loss is
generally to be looked for at the
soldering points connecting the
various components or in an eventual
hole in the evaporator made by the
user.
Leakage must be
eliminated by
re-soldering the
defective point or
substituting the
damaged
evaporator.
Excessively
full
This defect is indicated by the presence
of water outside refrigerator near the
motor caused by formations of ice on
the return tube.
If in the refrigerant system a quantity
of R600a is introduced which is
greater than that indicated, the excess
gas dose not terminate its expansion
in the evaporator but proceeds into
the return tube.
The system must be
emptied and
subsequently refilled
introducing the
correct quantity of
R-600a.
Humidity in
the system
This defect is indicated by the partial
frosting of the evaporator and by
continual defrosting cycles determined
by the interruption of the flow of gas on
the evaporator. the motor compressor
keeps running.
The refrigerant system is humid when
there is a small percentage of water
present which not completely retained
by the dehydrator filter, enters into
circulation with the Freon and freezes
at the capillary exit in the evaporator.
The system must be
emptied and then
refilled after
eliminating the
humidity.
Presence of
air in the
system
Poor performance of the refrigerant
system which is indicated: on the
evaporator with a slight frost which
dose not freeze and an excessive
overheating of the condenser and
motor-compressor.
There is air in a refrigerating system
when during the filling phase vacuum
is not effected or it is not adequately
done.
Group must be
drained and
subsequently refilled
after carefully
creating vacuum.
Blocked
capillary
Because of the lack of circulation Freon
in the system, there is no frosting of the
evaporator, while a slight overheating
of the first spiral of the condenser is
noted.
Eventual impurities contained in the
Freon or in the components of the
refrigeration system before assembly
and not retained by the filter can
obstruct the capillary.
To restore the system
it must be emptied,
substitute the
capillary or the
evaporator entirely
in case the capillary
is coaxial with
respect to the return
tube, then refill it.
Motor

The system dose not work and the
“clixson” intervenes interrupting
delivery to the motor- compressor.
In case of short circuit the breakdown
is due to the electric winding if
blocked, there is a mechanical failure
in the motor-compressor.
The
motor-compressor
must be replaced
and then proceed
with refilling.

and then proceed
with refilling.
Noisy
motor-comp
ressor
In case of mechanical failure in the
motor-compressor there in an excessive
noise when the system is functioning in
case a suspension spring is unhooked
banging will be heard and there will be
especially strong vibrations when the
system starts up and stops.
The cause of the excessive noise is
normally to be sought for in a
mechanical break down and only
rarely in the unhooking of one of the
suspension springs.
The
motor-compressor
must be substituted
and then proceed
