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.

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
compressor
short-circuite
d or blocked

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.

Motor-compr
essor dose
not compress

No frost forms on the
evaporator even if the
motor-compressor is apparently
running regulary

In this case there is a mechanical
failure in the diaphram valves
which remaining continually open,
do not permit the piston to suck and
compressor the which
consequentely dose not circulate in
the system.

The motor-compressor
must be replaced and then
proceed with refilling.

Noisy
motor-compr
essor

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 with the
refilling.
