Service manual

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.

DEFECT EFFECT

Group Evaporator dose not frost even though motor-compressor runs continually. partially or completely out of refrigerant charge

Excessively full

Humidity in the system

Presence of air in the system

This defect is indicated by the presence of water outside refrigerator near the motor caused by formations of ice on the return tube.

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.

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.

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.

CAUSE

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

REMEDY

Leakage must be eliminated by re-soldering the defective point or substituting the damaged user.

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 refrigerant system is humid when there is a small percentage of water present which not completely retained by the dehydrator filter, enters into evaporator.

The system must be emptied and subsequently refilled introducing the correct quantity of

R-600a.

The system must be emptied and then refilled after eliminating the circulation with the Freon and freezes at the capillary exit in the evaporator. humidity.

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.

In case of short circuit the breakdown is due to the electric winding if blocked, there is a mechanical failure in the motor-compressor.

In this case there is a mechanical failure in the diaphram valves which remaining continually open, do not

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.
