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. When servicing evaporator part, wear cotton gloves to
prevent injury by sharp fins of the evaporator.
9. 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.
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)
