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.

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.

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

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

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.

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.
and poor contact may cause.
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.
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.

If applying forcible power or strike (dropping or careless

Hermetic Terminal, the result may be poor operation

PROTECTOR(O.L.P)
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.
Note for
to
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,
Motor is worn away and causes circuitshort and fire. Therefore, use a properly fixed OLP
without fail.
The higher the temperature is, the higher becomes the
resistance value. These features are used as starting
device for the Motor.
Compressor
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
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.

CONTACTING
POINT
1) Definition of OLP
(1) OLP (OVER LOAD PROTECTOR) is attached to the
Hermetic Compressor and protects the Motor by cutting
off current in Compressor Motor in case of over-rising
temperature by Bimetal in the OLP.
(2) When over-voltage flows to Compressor motor, the
Bimetal works by heating the heater inside the OLP,
and the OLP protects Motor by cutting off current which
flows to the Compressor Motor.

2) Role of the OLP
(1) The OLP is attached to the Hermetic Compressor used

normal operation of the OLP.
