⑷Screw off the screws on the controlboard cover.
⑸Take off the controlboard cover.
(6) Screw off the screws on the controlboard.
⑺Pullout the terminalon the controlboard.

⑻Checkthe fuse, if the resistance is infinite, it showsthe fuse is damaged, pleasereplacethecontrolboard.
⑼Replace witha newcontrol board.
⑽Fix it withthe screws.

⑾Plug the terminalon the controlboard.
⑿Recover the controlboard cover.
⒀Fix the control boardcover.
⒁Fix the back panel withscrews.

④ Checkthe voltage inthesocket. Seethe following.
The voltageshouldbetween 105V to 126V in thesocket,ifitisn twithintherange, pleasecontact the local
power supplyadministration.
⑤Checkif the refrigerantsystemis leakage.
⑴Pullout the plug.
⑵Screw off the screws on the back panel.
8

⑶Take off the back panel.
⑷If compressor is shaking when you touch it by hand, this shows compressor is working.
⑸If exhaust pipe isn t hot felt by hand after compressor running a period of time.
9

⑹Theintake pipeisntcool by hand.
Then we cansay machine has the problem of System Leakage.
Method:
a. Cut process tube.
b. Take off the process tube.
10

c. Replace a new process tube
d. Weldthe process tube
e. Install the vacuumizing connector ontothe process tube.
11

f. 0.8Mpa
Charge nitrogen. Connect the dried Nitrogen that the pressure is 0.8Mpa to the process tube
g.Cover the welding point with towel that is soaked with soapsuds. If there is bubbles that
means there is seam.
12

h.Re-weld the parts at which there are seams
i. Test with towel as charging Nitrogen until there are no bubbles.
j. Connect the vacuum pump with the processing tube and then vacuumize for more than 20 minutes.
13

k.Connect the vacuum pump with canned bottle and then vacuumize for about 5 minutes.
l. Weigh up the canned bottle.
m. Charge the refrigerant into the canned bottle. (about 62g)
14

n. Weigh the canned bottle with refrigerant
o. Connect the canned bottle with the process tube and then compressor work for more than 5
minutes, charge the refrigerant into compressor
p. Weigh the canned bottle for check the refrigerant were charged completely
15

q. Clamp the process tube and make it flat, and seal it after ensuring no leakage of the gas.
r. Connect the refrigeration system to power and check is there any problems and then fit in
the back panel
16

⑥If the refrigerant system has no leakage, we should check if there is any block in the tubes.
⑴Cut off the capillary from the filter, if the gas pushed out through the filter meanwhile
no gas through the capillary, it shows there is block in the tubes.
⑵Take off the filterwiththewelding torchand replace a newone.
⑶Rechargethe nitrogen gas, vacuumizethe machineand recharge therefrigerantas above methods.
2. The wine cellarisnotcooling enough.
① Avoidthe cellarin directsunlight oradjacentto heatsource. Keeplight inthe cabinet on result in too
high inner temperature.
② Ensure the good ventilation around thecellar.
③ Checkand ensurethe door closed well or keepit open not too long time.
④ Checkand ensurethe door gasketis good enough.
17

⑤Checkif the refrigerantsystemis leakage.
⑥Checkif the condenser fan motoris rotating. Method：
⑴Screw off the screws on the back panel.
⑵Take off the back panel.
18

If the fan motor is not running when the compressor is working, and the connectors are proper fixed, please repair
it asfollowing:
a. Screw off the fixedscrewson the fan motor.
19

b. Take out the fan motor.
c. Pullout the blade.
d. Pullout the terminal.
