P leas e read the following instructions before s ervicing your
refrigerator.
1. C heck the s et for electric los ses .
2. Unplug prior to servicing to prevent electric s hock.
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.
5. D on't touc h me ta l produc ts in the fre e z e r with we t
hands. This may cause fros tbite.
6. P revent water from following onto electric elements in
the mechanical parts.
7. W hen s ta nding up a fte r ha ving c he c ke d the lowe r
s ection of the refrigerator with the upper door open,
move with care to avoid hitting the upper door.
8. When tilting the set, remove any materials on the set,
es pecially the thin plates (ex. G las s shelf or books .)
9. When s ervicing the evaporator, wear cotton gloves .
10. Lea ve the dis ass embly of the refrigerating cycle to a
s pecialized s ervice center. T he gas ins ide the circuit
may pollute the environment.
11. When you dis charge the refrigerant, wear the protective
safety glass es or goggle for eye safety.
12. When you repair the cycle s ys tem in refrigerator, the
work area is well ventilated.
E specially if the refrigerant is R 600
heat sources. (No smoking)

F ea tures of refrigera nt (R 600a)
•Achromatic and odor less gas.
•F lammable gas and the ignition (explosion) at 494°C .
•Upper/lower explosion limit: 1.8% ~8.4% /V ol.
F ea tures of the R 600a refrigerator
•C harging of 60% refrigerant compared with a R 134a model.
•The suction pressure is below 1bar (abs) during the operation.
•B ecaus e of its low s uction pressure, the external air may ow
in the cycle system when the refrigerant leak, and it caus es
malfunction in the compressor.
•T he dis pla ce ment of compressor us ing R 600a mus t be a t
leas t 1.7 times larger than that of R 134a.
•Any type of dryer is applicable (XH-5, 7, 9).
•The E VAP OR AT OR or any other cycle part that has welding
joint is hidden in the foam. (If not hidden inside, the whole
ele c tric pa rts mus t be te s te d with the L E AK A G E T E S T
according to the IE C S tandard.)
•The compressor has label of the refrigerant R 600a.
•Only the S VC man mus t have an access to the system.
After the refrigerant (R 600a) is completely dis charged,
repair any defective parts and replace the dryer. At any
cas e you must us e the LOK R ING for connecting or replacing
any part in the cycle (No F ire, No Welding). C harge the N2
gas in order to check for leakage from welding points and the
LOK R ING . If leakages are found, repair the defects again.
C onnect the S chrader valve to pump with the coupler. And
then turn the pump on for vacuum state (F igure 3). Let the
pump run until the low pressure gauge indicates the vacuum
(gauge pressure -1atm or -760mmHg, absolute pressure 0 ).
R ecommended vacuum time is 30 min.
After the s ys tem is completely va cuume d, ll it with the
refrigera nt R 600a up to what ha s been s pecied at your
refrigerator Name P late. T he amount of refrigerant (R 600a)
mus t be prec is ely mea s ured within the error of ±2g by an
electron scale (F igure 4).
If you us e the manifold connected with both the refrigerant
(R 600a) cylinder and the vacuum pump simultaneous ly, make
sure the pump valve is closed (F igure 5).
C onne c t the c ha r ging hos e ( tha t is c onne c te d to the
refrigerant (R 600a) cylinder) to the S chrader valve ins talled
on the s ervice tube. T hen, charge the refrigerant (R 600a) by
controlling the T hrottle valve. W hen you do s o, do not fully
open the Throttle valve because it may make damage to the
compressor. G ra dua lly cha rge the refrigerant (R 600a ) 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 reuence. C lose the S chrader valve cap after the
refrigerant (R 600a) is completely recharged.
A fte r you c omple tely re c ha rge the refrige ra nt ( R 600a ) ,
perform the leakage tes t by using a portable leakage detector
or s oa py wa te r. T e s t the low pre ssure (s uction) pa rts in
compressor o time and high pressure parts in compressor
on time. If the leakages are found, restart from the refrigerant
(R 600a) dis charging process and repairs defects of leaks .
After the leakage tes t, check the temperature of each parts of
the cycle. C heck with hands if the C ONDE NS E R a nd the
cas e (HOT -LINE pipe) that is contacted to the door gas ket
are warm. C onrm that fros t is uniform dis tributed on the
surface of the E V AP OR AT OR .
Ins tallation place
•Must be well ventilated.
•Must be 20 m3or larger.
•Must be no-s moking area.
•No ignitable factors must be pres ent.
Utilities
•R efrigerant cylinder (MAX NE T 300g)
•Manometer
•Vacuum pump (600ℓ/min)
•P iercing C lamp
•Quick coupler
•Hos es (5m-1E A, 1m-3E A)
•LO K R ING
•P ortable Leakage detector (3g/year)
•Nitrogen cylinder (for leakage tes t)
•C oncentration gauge
Make s ure before S ervicing
•R efrigerant
C onrm the refrigerant by checking Name P late and the label
on the compressor, after opening the C OVE R ASSE MB LY ,
B AC K -M/C .
•If the refrigerant is R 600a, you must not weld or apply a heat
source.
Air R echarging in C ompressor
B efore relling the re frigera nt, you mus t perform the tes t
according to C hapter 5 (T R OUB LE S HOOT ING C HAR T ). When
the de fe cts a re found, you mus t dis c ha rge the re s idua l
re frige r a nt ( R 600a ) in the outdoor. F o r dis c ha rging th e
refrigerant R 600a, break the narrow portion of tube extens ion
by hand or with a pipe cutter as shown in Figure 1. Leave it for
30min in outs ide to s tabilize 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 outs ide.
Attach the s ervice tube installed with a S chrader valve (one-
way valve) by using the LOK R ING (F igure 2). T hen, connect
the S c hra de r va lve ( one -wa y va lve ) to the pump tha t is
connected to the dis cha rging hos e le ading to the outs ide .
When dis charging the res idual refrigerant, repeat 3 cycle that
includes 3min of the pump running->pump o->30s ec of the
compressor running.

COMPRESSOR
1. Inverter Linear Compressor
1) Method to Measure Compressor Winding Resistance
Normal Determination Criteria.
The compressor winding resistance can be determined as normal if resistance values show the values as described in
below gure when measuring resistance values of the harness (connected with compressor) to connect.
Connect201(CON201) of the main PWB as shown in below gure.
Check for defect of the inverter linear compressor in following orders:
Defect Determination Criteria
•Check connection status of the Compressor Connection Harness-P(Lead Wire) which is located at the M/C room where
resistance values measured at the CON201 Housing are shown as innite or several hundred MΩ . Separate connecting
wires of the M/C room (A-point in Figure) and then measure resistance values at the connecting wires again. The
compressor can be determined as normal if resistance values are shown as standard resistance value. Check connection
status of a harness.
Defect at M/C room connection contact or CON201 Housing contact, short-circuit of harness)
•Where resistance values measured at A-point are also shown as innite or several hundred MΩ , disassemble a cover PTC
of the compressor terminal and check the terminal connecting status at the B-point in Figure.
•Where there is no failure in the wiring status and resistance values are shown as innite or several hundred MΩ , it may be
determined as defect of compressor.
•Since if there is no failure in resistance values of the compressor, it may be defective Main PWB, replace the Main PCB
and check for normal operation of the compressor.
•When determining any defect through resistance measuring, it can be determined as normal if resistance values show as
descried in the below gure by measuring ①power and ③common terminal or ②full power and ③common terminal.
However, resistance values are measured when measuring ①power and ②full but measuring is meaningless since they
cannot become criteria for determining defect (measuring not required).
Caution
1. Be sure to powering o the refrigerator and measure after several minutes has passed.
2. If not accurately measuring resistance, wrong determination may be guided. (Dierence of resistance value of several W
or so may occur.)
