SAFETY PRECAUTIONS
Please read the following instructions before servicing your
refrigerator.
8. When tilting the set, remove any materials on the set,
especially the thin plates(ex. Glass shelf or books.)
1. Check the set for electric losses.
2. Unplug prior to servcing to prevent electric shock.
9. When servicing the evaporator, wear cotton gloves.
This is to prevent injuries from the sharp evaporator
fins.
3. Whenever testing with power on, wear rubber gloves to
prevent electric shock.
4. If you use any kind of appliance, check regular current,
voltage and capacity.
10. Leave the disassembly of the refrigerating cycle to a
specialized service center. The gas inside the circuit
may pollute the environment.
5. Don't touch metal products in the freezer with wet
hands. This may cause frostbite.
11. When you discharge the refrigerant, wear the
protective safety glasses or goggle for eye safety.
6. Prevent water from following onto electric elements in
the mechanical parts.
12. When you repair the cycle system in refrigerator, the
work area is well ventilated.
Especially if the refrigerant is R600a, there are no fire
or heat sources. (No smoking)
7. When standing up after having checked the lower
section of the refrigerator with the upper door open,
move with care to avoid hitting the upper door.

SERVICING PRECAUTIONS
Features of refrigerant (R600a)
After the refrigerant (R600a) is completely discharged, repair any
defective parts and replace the dryer. At any case you must use the
LOKRING for connecting or replacing any part in the cycle (No Fire,
No Welding). Connect the Schrader valve to pump with the coupler.
And then turn the pump on for vacuum state (Figure 3). Let the
pump run until the low-pressure gauge indicates the vacuum (gauge
pressure 0, absolute pressure -1atm or -760mmHg). Recommended
vacuum time is 30 min. Charge the N2 gas in order to check for
leakage from welding points and the LOKRING. If leakages are
found, repair the defects and repeat the vacuum process.
• Achromatic and odor less gas.
• Flammable gas and the ignition (explosion) at 494°C.
• Upper/lower explosion limit: 1.8%~8.4%/Vol.
Features of the R600a refrigerator
• Charging of 60% refrigerant compared with a R134a model
• The suction pressure is below 1bar (abs) during the operation.
• Because of its low suction pressure, the external air may
flow in the cycle system when the refrigerant leak, and it
causes malfunction in the compressor.
• The displacement of compressor using R600a must be at
least 1.7 times larger than that of R134a.
• Any type of dryer is applicable (XH-5, 7, 9).
• The EVAPORATOR or any other cycle part that has
welding joint is hidden in the foam. (If not hidden inside,
the whole electric parts must be tested with the
LEAKAGE TEST according to the IEC Standard.)
• The compressor has label of the refrigerant R600a.
• Only the SVC man must have an access to the system.

Installation place
After the system is completely vacuumed, fill it with the refrigerant
R600a up to what has been specified at your refrigerator Name
Plate. The amount of refrigerant (R600a) must be precisely
measured within the error of ±2g by an electron scale (Figure 4).
• Must be well ventilated.
• Must be 20 m3 or larger.
• Must be no-smoking area.
• No ignitable factors must be present.
If you use the manifold connected with both the refrigerant
(R600a) cylinder and the vacuum pump simultaneously,
make sure the pump valve is closed (Figure 5).

Before refilling the refrigerant, you must perform the test according
to Chapter 5 (TROUBLESHOOTING CHART). When the defects
are found, you must discharge the residual refrigerant (R600a) in
the outdoor. For discharging the refrigerant R600a, break the
narrow portion of tube extension by hand or with a pipe cutter as
shown in Figure 1. Leave it for 30min in outside to stabilize the
pressure with ambient. Then, check the pressure by piercing the
dryer part with piercing pliers. If the refrigerant is not completely
discharged, let the refrigerator alone for more 30min in outside.

Connect the charging hose (that is connected to the refrigerant
(R600a) cylinder) to the Schrader valve installed on the service
tube. Then, charge the refrigerant (R600a) by controlling the
Throttle valve. When you do so, do not fully open the Throttle valve
because it may make damage to the compressor. Gradually charge
the refrigerant (R600a) by changing open and close the Throttle
Valve (5g at each time). The charging hose must use a one-way
valve to prevent the refrigerant refluence. Close the Schrader valve
cap after the refrigerant (R600a) is completely recharged.

After you completely recharge the refrigerant (R600a), perform the
leakage test by using a portable leakage detector or soapy water.
Test the low pressure (suction) parts in compressor off time and
high pressure parts in compressor on time. If the leakages are
found, restart from the refrigerant (R600a) discharging process and
repairs defects of leaks.
Figure 2
Attach the service tube installed with a Schrader valve (one-way
valve) by using the LOKRING (Figure 2). Then, connect the
Schrader valve (one-way valve) to the pump that is connected to
the discharging hose leading to the outside. When discharging the
residual refrigerant, repeat 3 cycle that includes 3min of the pump
running->pump off->30sec of the compressor running.
After the leakage test, check the temperature of each parts of the
cycle. Check with hands if the CONDENSER and the case (HOTLINE pipe) that is contacted to the door gasket are warm. Confirm
that frost is uniform distributed on the surface of the EVAPORATOR.

1) Role
The compressor intakes 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.

2) Composition
The Compressor is Composed of Compressor Apparatus
compressing gas, Compressor Motor moving Compressor
Apparatus and Case protecting Compressor Apparatus
and Motor. There is Relay Assy (one set of PTC-Starter
and Over Load Protector (OLP)) in Compressor. On the
other hand, because the Compressor consists of
1/1000mm processing precision components and is sealed
after production in absence of dust or humidity, deal and
repair with care.

3) Note for Usage
(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, the result may be poor operation
and poor contact may cause.
(5) Be careful that dust, humidity, and flux welding don't
inflow in the Compressor inside in replacing the
Compressor. Dust, humidity, and flux due to welding
which inflows to Cylinder may cause lockage and noise.

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 the Compressor Motor, PTC
elements generate heat continuously. Therefore,
if PTC isn't cooled for a while after the power has been
shut off, Motor can't operate again.
5) Relation of PTC-Starter and OLP
(1) If the power is off during operation of Compressor and
the power is on before the PTC is cooled, (instant shutoff within 2 min. or reconnect a power plug due to
misconnecting), the PTC isn't cooled and a resistance
value grows. As a result, current can't flow to the subcoil and the Motor can't operate and the OLP operates
by flowing over current in only in the 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 circuitshort and fire. Therefore, use a properly fixed OLP
without fail.
2 PTC-STARTER
1) Composition of PTC-Starter
(1) PTC (Positive Temperature Coefficient) is a no-contact
semiconductor starting device which uses ceramic
material and this material consists of BaTiO3.
(2) The higher the temperature is, the higher becomes the
resistance value. These features are used as starting
device for the Motor.
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 to
single-phase induction Motor.
For normal operation of the single-phase induction
motor, in the starting operation flows in both main coil
and sub-coil. After the starting is over, the current in
subcoil is cut off. The proper features of PTC play all
the above roles. So, PTC is used as a motor starting
device.
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 away enter the PTC,
PTC materials it may break due to insulation breakdown
of the material itself.
(4) Don't change PTC at your convenience.
Don't disassemble PTC and mold. If the exterior to the
PTC-starter is damaged, resistance value is altered and
it may cause poor starting of the compressor motor may
cause.
(5) Use a properly fixed PTC.

2 FUNCTION DESCRIPTION
1) ELECTRIC CIRCUITS
TRANS secondary side is composed of electric power circuits for RELAY driving electricity (12Vdc) and for supplying
electricity to MICOM and IC (5Vdc). The voltage in each part is as follows.
PARTS
both ends of VA1
both ends of CM1
both ends of CM2
both ends of CE2
both ends of CC2
VOLTAGE
230Vac
14Vac
17Vdc
12Vdc
5Vdc
VA1 is the part to protect over voltage and noise. When more than 385V is applied, the thermal-fuse(130°C cut-off, local
option) in a first part of TRANS is cut so that the elements in the secondary side of TRANS are protected.
2) OSCILLATION CIRCUIT
CIRCUIT for occurring CLOCK which motivates the internal local element of IC1 to transmit and receive an information and
BASIC TIME for calculating time. Use a proper form for OSC 1. Because in case that SPECIFICATION is changed, the
calculated time in IC1 is changed or IC1 isn't able to operate.
3) RESET CIRCUIT
All the internal parts of MICOM(IC1) return to the initial condition when the early power ON or apply power again in MICOM
after temporary power failure. As a result, all the functions operate according to the early condition. At the early period of
power ON the "LOW" voltage is applied in the RESET terminal of MICOM for the fixed time. The RESET terminal is 5V
during the general operation.
