Far Infrared Rays emitted from Far Infrared Ray Lamp restrains the dryness of the foods and keeps its
original form without transforming.

●

By increasing the nucleic acid, Far Infrared Rays also keeps the aroma and the smell of the food for a
long time.

●

It is useful to store the food without seasoning such as salt or
sugar, and the food needed to keep as low temperature with
the raw food uncooked heating or no disinfecting.
- (Sliced) : Raw Fish, Meat, Poultry and so on

●

It is useful to keep the original taste of the food by F.I.R's the
restraining excessive fermentation and overripe of the foods.
- Vegetable with spices, Yogurt, and so on

●

It is useful to store the unsuited foods in the Freezer among
the cooked foods or that go bad easily.
- Boiled Egg, Bamboo Shoots, Vegetable for seasoning, and

so on

●

When the refrigerator begins to operate, F.I.R Lamp
turns on. During the refrigerator's operating, the on and
off of the F. I. R Lamp is automatically controlled by the
refrigerator inner temperature.
Therefore it is not necessary to handle F.I.R Lamp.

●

F.I.R Lamp is coated with special materials for the vest
results of F.I.R Lamp's effect decreases.

●

If F.I.R Lamp is veiled or covered, the F.I.R Lamp's effect
decreases.

●

If you store the foods wrapped in the vinyl or wrapper, not in the vessel with lid, the foods will get more
effective F.I.R results.

●

If you want to check the F.I.R Lamp operation, don't touch F.I.R Lamp because you may burn your fingers
with the high temperature of its surface.

●

During F.I.R Lamp operation, don't touch F.I.R Lamp because you may burn your fingers
with the high temperature of its surface.

●

Store fresh food in the refrigerator compartment. How food is frozen and defrosted is an important factor
in maintaining freshness and flavor.

●

Do not store food which goes bad easily at low temperatures, such as bananas, pineapples, and melons.

●

Allow hot food to cool prior to storing. Placing hot food in the refrigerator could spoil other food, and lead
to high electric bills!

●

When storing, wrap food in vinyl, or place in a covered container. This prevents moisture from
evaporating, and helps food to keep its taste and nutritional valve.

●

Do not block air vents with food. Smooth circulation of chilled air keeps refrigerator temperatures even.

●

Do not open the door frequently. Opening the door lets warm air enter the refrigerator, causing
temperatures to rise.

●

To adjust the temperature control easily, do not store food near the temperature control dial.

●

Do not store bottles in the freezer compartment - they may break when frozen.

●

Do not refreeze food that has been defrosted. This causes loss of taste and nutritional valve.

●

When storing frozen food like ice cream for a long period, place it on the freezer shelf, not in the door
rack.

●

Loading for Freezing - It is recommended to load newly introduced foods on the following position for
freezing:

●

Avoid placing moist food on deep interior refrigerator shelves, it could freeze upon direct contact with
chilled air. To avoid this it is better to store food in the covered container.

●

Always clean food prior to refrigeration. Vegetables and fruits should be washed and wiped, and packed
food should be wiped clean, to prevent adjacent food from spoiling.

●

When storing eggs in their storage rack, ensure that they are fresh, and always store them in a up-right
position, which keeps them fresh longer.

●

Door rack - Loading the food on the whole area of door rack would cause no problems in performance.

●

If you keep the refrigerator in a hot, and humid place, frequently open its door or put a lot of
vegetables in it, dew may form in it, which has no effect on its performance. Remove the dew with
dust cloth free from care.

The compressor inhales low temperature and low pressure
gas evaporated from Evaporator of the Refrigerator, and
condenses this gas to high temperature and high pressure
gas, and then plays delivering role to Condenser.

4-1-2 Composition
The Compressor is Composed of Compressor Apparatus
compressing gas, Compressor Motor moving Compressor
Apparatus and Case protecting Compressor Apparatus
and Motor. There are PTC-Starter, and Over Load
Protector (OLP) in the Compressor outside. On the other
hand, because the Compressor consists of 1/1000mm processing
precision components and is sealed after producing without dust
or humidity, deal and repair with care.

4-1-3 Note to Use
(1) Be careful not to allow over-voltage and over-current.
(2) No Strike 

If applying forcible power or strike (dropping or careless
dealing), poor operation and noise may occur.

(3) Use proper electric components appropriate to the

Compressor.

(4) Note to Keep Compressor.

If Compressor gets wet in the rain and rust in the pin of
Hermetic Terminal, poor operation and poor contact
may cause.

(5) Be careful that dust, humidity, and flux due to welding

don't inflow in Compressor inside in replacing
Compressor. Dust, humidity, and flux due to welding
which inflows to Cylinder may cause lock and noise.

4-2-1 Composition of PTC-Starter
(1) PTC (Positive Temperature Coefficient) is no-contact

semiconductor starting device which uses ceramic
material and the material consists of BaTiO

3

.

(2) The higher the temperature is, the higher resistance

value becomes . These features are used as starting
device of Motor.

4-2-2 Role of PTC-Starter
(1) PTC is attached to Hermetic Compressor used for

Refrigerator, Show Case and starts Motor.

(2) Compressor for household refrigerator applies single-

phase induction Motor.
For normal operation of single-phase induction motor, in
the starting operation flows in both main coil and sub-
coil. After the starting is over, the current is cut off in
subcoil. The proper features of PTC play the above all
roles. So, PTC is used as a starting device of motor.

● 

4-2-4 Motor Restarting and PTC Cooling
(1) For restarting after power off during normal

Compressor Motor operation, plug the power cord after
5 min. for pressure balance of Refrigerating Cycle and
PTC cooling.

(2) During normal operation of Compressor Motor, PTC

elements generate heat continuously. Therefore, 
if PTC isn't cooled for a while after power off, Motor
can't operate again.

4-2-5 Relation of PTC-Starter and OLP
(1) If power off during operation of Compressor and power

on before PTC is cooled, (instant shut-off within 2 min.
or reconnect a power plug due to misconnecting), 
PTC isn't cooled and a resistance value grows. As a
result, current can't flow to the sub-coil and Motor can't
operate and OLP operates by flowing over current in
only main-coil.

(2) While the OLP repeats on and off operation about 3-5

times, PTC is cooled and Compressor Motor performs
normal operation.
If OLP doesn't operate when PTC is not cooled,
Compressor Motor is worn away and causes circuit-
short and fire. Therefore, use a proper fixed OLP
without fail.

4-2-6 Note to Use PTC-Starter
(1) Be careful not to allow over-voltage and over-current.
(2) No Strike

Don't apply a forcible power or strike.

(3) Keep apart from any liquid.

If liquid such as oil or water inflows into PTC, 
PTC materials it may break due to insulation
breakdown of material itself.

(4) Don't change PTC at your convenience.

Don't disassemble PTC and mold. If damaging to
outside of PTC-starter, resistance value alters and poor
starting of compressor motor may cause.

(5) Use a properly fixed PTC.

4-3-1 Definition of OLP
(1) OLP (OVER LOAD PROTECTOR) is attached to

Hermetic Compressor and protects Motor by cutting off
current in Compressor Motor by Bimetal in the OLP in
case of over-rising temperature.

(2) When over-voltage flows to Compressor motor, Bimetal

works by heating the heater inside OLP, 
and OLP protects Motor by cutting off current which
flows to Compressor Motor.

4-3-2 Role of OLP
(1) OLP is attached to Hermetic Compressor used to

Refrigerator and Show Case and prevents Motor Coil
from being started in the Compressor.

(2) Do not turn the Adjust Screw of OLP in any way for

normal operation of OLP.
