Please read the followings before servicing your refrigerator.
1. Check if an electric leakage occurs in the set.
2. To prevent electric shock, unplug prior to servicing.
3. In case of testing with power on, wear rubber gloves to
prevent electric shock.
4. If you use any appliances, check regular current, voltage
and capacity.
5. Don't touch metal products in cold freezer with wet hand.
It may cause frostbite.
6. Prevent water flowing to electric elements in mechanical
parts.
7. When you stand up during observing the lower part
with the upper door open, move with care to prevent
head wound which may happen by hitting the upper
door.
8. When sloping the set, remove any materials on the set,
especially thin plate type (ex.: glass shelf or books.)
9. When servicing evaporator part, wear cotton gloves
without fail. It is to prevent wound by sharp fin of
evaporator.
10. Leave a breakage of refrigerating cycle to a heavy
service center. The gas in cycle inside may soil
ambient air.

AIR RECHARGING IN COMPRESSOR
Test the refrigeration system connecting it electrically before
refilling operation. It is necessary to ascertain the function
of the motor-compressor and identify the defects
immediately. If the defects have been found, empty the old
system of eventual R-12(R134a) residue by breaking off the
end of the extension piece at its narrow point. (Figure 1)
Replace the filter and any damaged components. Unsolder
and pull off the piece remaining inside the service tube and
then attach an extension completely with male Hansen and
last, solder it to the same tube again. (Figure 2)
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 so 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 30
minutes. (Figure 3)
In case that a considerable leakage occurs and to stop the
vacuum pump will be necessary and add a small quantity
of Freon to the system, if vacuum should not be obtained
(pressure gauge can't fall to 1 atmosphere), start the
refrigeration unit and find the leakage with the special leakfinder. When the defective soldering point is visible, re-do it
after opening the extension tube valve and reestablishing
the normal outside pressure inside the group.
Because the melted alloy is sucked into the tubes and
block them, the pressure must be rebalanced when
vacuum is in the system in soldering. As soon as the
vacuum operation is over, add the quantity in grams of
R-12(R134a) to the refrigerant system. Remember that
every system has an exact quantity of R-12(R134a) with a
tolerance of ±5 grams that can be added. (Figure 4)
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 for adding to the system. (Figure 5)
In addition, check the graduated scale on the cylinder for
the quantity of R-12(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
R-12(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 R-12(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.
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 to the quantity of R-12(R134a) established
for the system being charged. When the system is running,
the suction pressure must be stabilized between 0.30 to
0.6(0.10 to 0.4) atmosphere.
