P lea se read the following instructions before servicing your
refrigerator.

1. Check the s et for electric los ses.

2. Unplug prior to s ervicing to prevent electric s hock.

3. Whenever testing with power on, wear rubber gloves to
preve nt electric s hock.

4. If you use any kind of applianc e, check regular current,
voltage a nd capacity.

5. Don't touch meta l products in the fre ez er with we t
hands . This ma y ca us e fros tbite.

6. Prevent water from following onto electric eleme nts in
the me cha nical par

7. Whe n s tan ding up a fter ha ving c hecked the lowe r
s ection of the refrige ra tor with the uppe r door open,
move with care to avoid hitting the upper door.

ts.

8. When tilting the s et, remove any materials on the set,
es pecially the thin plates(ex. Glas s s helf or books.)

9. When s ervicing the e vaporator, wear cotton gloves.

10. L eave the disas s embly of the refrigerating cycle to a
s pecialized servic e ce nter. T he ga s ins ide the circuit
may pollute the environment.

11. W hen you discharge the refrigerant, wea r the protective
safety glasses or goggle for eye s afety.

12. W hen you repair the c yc le sys tem in refrige ra tor, the
work area is well ventilated.
E specially if the refrigerant is R 600

F eature s of refrigerant (R 600a)

• Achromatic and odor less gas.

• Flamma ble gas and the ignition (explos ion) a t 494°C .

• Upper/lowe r explos ion limit: 1.8% ~8.4% /V ol.

F eature s of the R 600a refrigerato r

• C harging of 60% refrigerant compared with a R134a model.

• The s uction pre ssure is below 1bar (abs) during the operation.

• Becaus e of its low suction pressure, the external air may ow

in the cyc le s ystem when the refrigera nt lea k, and it causes
malfunc tion in the compressor.

• The dis placement of compressor using R 600a mus t be at
least 1. 7 times la rger than that of R 134a.

• Any type of drye r is applicable (X H-5, 7, 9).

• The E VAP OR AT OR or any other cycle part that has welding

joint is hidde n in the foam. ( If not hidden inside, the whole
ele ctric parts mus t be tes ted with the LE AK AG E T E S T
according to the IE C S ta ndard.)

• The compressor ha s label of the refrigerant R 600a.

• Only the S VC ma n must have an access to the system

.

Ins tallation place

• Mus t be well ventilated.

• Mus t be 20 m

• Mus t be no-s moking area.

• No ignitable fa ctors must be pres ent.

• V acuum pump (600

• P iercing C lamp

• Quick coupler

• Hoses (5m-1E A, 1m-3E A)

• LOKR IN

• P orta ble Leakage detector (3g/year

• Nitrogen cylinder (for leakage tes t)

• C oncentration gauge

After the refrigerant (R 600a) is completely discharged,
repair any defective parts a nd replace the drye r. At any
case you must us e the LOK R ING for connecting or replac ing
any part in the cycle (No F ire, N o W elding). C harge the N2
gas in order to check for leakage from welding points and the
LOK R ING . If lea kages are found, repair the defects again.
C onnect the S chra der va lve to pump with the couple
then turn the pump on for vacuum s tate (Figure 3). L et the
pump run until the low pressure ga uge indica tes the vacuum
(gauge pressure -1a tm or -760mmHg, absolute pressure 0 ).
R ecommended vacuum time is 30 min.

If you use the manifold connected with both the refrige rant

B efore relling the refrige rant, you mus t perform the te st
according to C hapter 5 (T R OU BL ES HOOT ING C HAR T). When
the de fects are found, yo u mu s t dis cha rge the re s idua l
re frig e ra nt ( R 600a ) in the ou tdoor. F or di s cha rg in g the
refrigerant R 600a, break the narrow portion of tube extens ion
by hand or with a pipe cutte r as shown in Figure 1. Lea ve it for
30min in outside to s tabilize the pressure with ambient. The n,
chec k the pressure by pie rcing the drye r part with pierci
pliers. If the refrigerant is not completely dis cha rged, let the
refrigerator alone for more 30min in outside.

on the service tube. Then, charge the refrigerant (R 600a) by
controlling the T hrottle va lve. W hen you
open the Throttle valve because it may make damage to the
compressor. Gra dua lly cha rge the refrige rant (R 600a ) by
cha nging open and close the Throttle Valve (5g a t ea ch time).
The cha rging hose must use a one-wa y valve to prevent the
refrigerant reuence. C lose the S chrader valve cap after the
refrigerant ( R 600a) is completely re cha rged.

Afte r you completely re ch a rge the re frige ra nt (R 600a ),

COMPRESSOR

1. Inverter Linear Compressor

Check for defect of the inverter linear compressor in following orders:

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.

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 ① power and ③ common terminal or ② full power and ③ common terminal.
However, resistance values are measured when measuring ① power and ② full 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.)

2) Method to Determine Defect of Inverter Linear Drive

Determination of Comp Operation

Separate the back cover at the rear of refrigerator and determine for possible operation while touching the compressor with
the hands with insulation gloves worn.

Comp Operation

- Determine possible trip by checking operation status if cold air comes out after opening the doors of the R-Room.

Protective Logic (Trip)

- To protect the compressor from abnormal operation, this logic is used to temporally stop the refrigerator when abnormal
operation occurs and to re-operate it after abnormal signal disappears.
