SAFETY PRECAUTIONS

Please read the following before servicing your refrigerator.

1.Check if electric leakage occurs in the set.

2.When servicing current applying parts, unplug prior to servicing.

3.If testing with power on, wear rubber gloves to prevent electric shock.

4.Be sure to check regular current, voltage, and capacity.

5.Don't touch metal products in a cold freezer compartment with wet hands. It may cause frostbite or other injury.

6.Prevent water flowing to electric elements in mechanical parts.

7.When tilting the set, remove any materials on the set, especially thin plate type (ex,: glass plates or books.)

8.Do not open the sealed refrigeration system. It could cause injury or pollute the air. Leave this job to an autherized servicer with the appropriate refrigerant recovery equipment.

9.Curatorial, combustible, explosive, corrosive and volatile goods cannot be stored in the chest freezer.

10.Turn off the power and open the door, take the goods to make defrosting when frost thickness is more than 5mm. Acuate or hard tools are not allowed to make defrosting.

11.Chemic reagent is not allowed when washing the chest freezer. Pls clean it both inside and outside with soft cloth in litmusless soap water or abluent.

AIR RECHARGING IN COMPRESSOR

Test the refrigeration system by connecting it electrically before beginning the refilling operation. This is necessary to ascertain the function of the motor-compressor and identify defects immediately. If defects have been found, empty the old system of R134a residue by breaking off the end of the extension piece at its narrow point.

(Figure 1) Use the appropriate refrigerant recovery equipment. Replace the filter and any damaged components. Unsolder and pull off the piece remaining inside the service tube and then attach an extension with male Hansen, and last, solder it to the same tube again. (Figure 2)

SERVICING PRECAUTIONS

It is necessary to execute the soldering operation with valve open so that the fumes caused by oil residue can come out freely without blowholes between two tubes during heating the point to be soldered.

The extension fitted with the male Hansen is connected to the female fitting of the vacuum pump tube. (Figure 3) Air evacuating from the system begins as soon as the pump starts. The refrigeration system must be kept under vacuum until the reading on the low-pressure gauge indicates vacuum (0 absolute, -1 atm., -760 mm hg.) In any case, it is advisable to keep the pump running for about 60 minutes. (Figure 4)

If case that a considerable leakage occurs, it will be necessary to stop the vacuum pump and add a small quantity of Freon to the system, if vacuum should not be obtained (pressure gauge doesn't fall to 1 atmosphere.) Start the refrigeration unit and find the leakage with a special leak-finder. When the defective soldering point is visible, repair it after opening the extension tube valve and reestablishing the normal outside pressure inside the system.

Because the melted solder is sucked into the tubes and blocks them, the pressure must be rebalanced when vacuum is in the system for soldering. As soon as the vacuum operation is over, add the quantity (in grams) of R134a to the refrigeration system. Remember that every system has an exact quantity of R134a with a tolerance of ±5 grams than can be added. (Figure 5)

Before performing this operation (if the vacuum pump and refilling cylinder are connected), make sure that the valve placed between the vacuum pump and refilling tube are closed to keep the Freon from adding to the system.(Figure 6)

In addition, check the graduated scale on the cylinder for the quantity of R134a to be added; for example, if we have 750 grams of Freon in the cylinder and must add 165 grams to the group, this amount will be reached when R134a has dropped to 585 grams, remembering that the indicator shows a lower limit of meniscus. Do this after choosing the scale corresponding to the gas pressure different scales reported as the same gas pressure indicated by the pressure gauge on the top of the column.

To make R134a flow into the system, open the valve placed at the base of the cylinder and connected to the filling tube. The amount of Freon cannot be added to the system all at once because it may cause a blocking of motor-compressor. Therefore, proceed by adding original quantity of about 20-30 grams and close the valve

immediately thereafter.

The pressure rises and the motor-compressor must start, sucking the gas and making the pressure go down again. Regulate the valve again, maintaining the same manner until reaching the quantity of R134a established for the system being charged. When the system is running, the suction pressure must be stabilized from 0.10 to 0.4 atmosphere.
