P lease read the following instructions before servicing your
refrigerator.
1. Check the set for electric losses.
2. Unplug prior to servicing to prevent electric shock.
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. Don't touch metal products in the freezer with wet
hands. This may cause frostbite.
6. P revent water from following onto electric elements in
the mechanical parts.
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.
8. When tilting the set, remove any materials on the set,
especially the thin plates(ex. Glass shelf or books.)
9. When servicing the evaporator, wear cotton gloves.
10. Leave the disassembly of the refrigerating cycle to a
specialized service center. The gas inside the circuit
may pollute the environment.
11. When you discharge the refrigerant, wear the protective
safety glasses or goggle for eye safety.
12. When you repair the cycle system in refrigerator, the
work area is well ventilated.
E specially if the refrigerant is R 600
heat sources. (No smoking)

Features of refrigerant (R600a)
• 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
• C harging of 60% refrigerant compared with a R 134a 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 compres s or.
• The displacement of compressor using R 600a must be at
least 1.7 times larger than that of R 134a.
• Any type of dryer is applicable (XH-5, 7, 9).
• The E VAPOR ATOR 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 IE C S tandard.)
• The compressor has label of the refrigerant R 600a.
• Only the SVC man must have an access to the system.
After the refrigerant (R 600a) is completely discharged,
repair any defective parts and replace the dryer. At any
case you must use the LOKR ING for connecting or replacing
any part in the cycle (No Fire, No Welding). Charge the N2
gas in order to check for leakage from welding points and the
LOKR 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 system is completely vacuumed, fill it with the
refrigerant R 600a up to what has been specified at your
refrigerator Name Plate. The amount of refrigerant (R 600a)
must be precisely measured within the error of ±2g by an
electron scale (Figure 4).
If you use the manifold connected with both the refrigerant
(R 600a) cylinder and the vacuum pump simultaneously, make
sure the pump valve is closed (Figure 5).
Connect the charging hose (that is connected to the
refrigerant (R 600a) cylinder) to the S chrader valve installed
on the service tube. Then, charge the refrigerant (R 600a) by
controlling the T hrottle valve. When you do so, do not fully
open the Throttle valve because it may make damage to the
compressor. Gradually charge 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 refluence. C lose the S chrader valve cap after the
refrigerant (R 600a) is completely recharged.
After you completely recharge the refrigerant (R 600a),
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
(R 600a) discharging process and repairs defects of leaks.
After the leakage test, check the temperature of each parts of
the cycle. Check with hands if the CONDENSER and the
case (HOT-LINE pipe) that is contacted to the door gasket
are warm. C onfirm that frost is uniform distributed on the
surface of the EVAPORATOR.
Installation place
• Must be well ventilated.
• Must be 20 m
3
or larger.
• Must be no-smoking area.
• No ignitable factors must be present.
Utilities
• R efrigerant cylinder (MAX NE T 300g)
• Manometer
• Vacuum pump (600ℓ /min)
• P iercing C lamp
• Quick coupler
• Hoses (5m-1E A, 1m-3E A)
• LOKRING
• Portable Leakage detector (3g/year )
• Nitrogen cylinder (for leakage test)
• C oncentration gauge
Make sure before Servicing
• R efrigerant
C onfirm the refrigerant by checking Name P late and the label
on the compressor, after opening the COVER ASSEMBLY,
BACK-M/C.
• If the refrigerant is R 600a, you must not weld or apply a heat
source.
Air R echarging in Compressor
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 (R 600a) in the outdoor. For discharging the
refrigerant R 600a, 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.
Attach the service tube installed with a S chrader valve (one-
way valve) by using the LOKR ING (Figure 2). Then, connect
the S chrader 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
compres s or running.
