Checks and Measures
Explain the principles of radiator.
• The radiator pipes are installed in the refrigerator case and partition plate
between the refrigerator and the freezer compartment in order to prevent
condensation formation. Particularly in summer or after installation of
refrigerator, it may feel hot but it is normal. If there is not enough space to
dissipate heat, it can be hotter due to lack of heat radiation. Please install a
refrigerator in a well-ventilated place and leave the clearance between
refrigerator and wall:
Explain that the hole is for releasing gas.
• A small hole in the door liner is for releasing gas during insulation materials
lining work. With a releasing hole, forming can be easily done .
Explain that the hole is to allow the air to escape when vacuum forming plastic
parts and pumping foam insulation into cavities.
NOTE! Holes and releasing gas appear to be very crude and would not be
acceptable in a manual.
There are small holes in the plastic liner of some parts of the refrigerator. These
holes allow plastic parts to be injection molded and vacuum formed by allowing
air bubbles to be expelled. They also allow foam insulation to be pumped into
cavities where air bubbles may build up.
Explain how to store foods
• Condensation forms when refrigerator is installed at damp area, door is
frequently opened, and wet foods are not stored in the air tight container or
wrapped. Be sure to store wet foods in airtight containers or securely covered in
plastic wrap.
When should the power be connected ?
• You can connect the power immediately after installation. However, if the
refrigerator was laid flat before or during installation, you must stand it upright
for 6 hours before plugging it in. This allows the refrigerant oils to return to the
sump in the compressor. If you operate the refrigerator before the oil has had a
chance to settle, you could damage the compressor.
Refrigerator compartment door does not open properly.
• When the door is open, warm open air comes into the compartment and is
mixed up with cool air. This mixed air shall be compressed and increase the
internal pressure when door is closed. This causes the door sticked closely to
the refrigerator in a moment. (If the refrigerator is used for a long time, it will
open smoothly.)
When the refrigerator compartment door is opened and closed, the freezer
compartment door moves up and down.
• When the refrigerator compartment door is opened and closed, fresh air comes into
the freezer compartment and moves up and down the freezer compartment door.
Door opens too easily.
• There is a magnet in the gasket so it closes securely without a gap. It can be
held open easily if something is in the way and obstructs the door's closing
A door does not close properly.
• If the refrigerator is not properly leveled, the doors will not close easily. Adjust
the level using the leveling screws under the front of the refrigerator.
