Danger
·Please make sure to discharge the rest refrigerant in the parts.
·When discharging refrigerant, make sure that it never go to the fire place and drain
to outdoors.
Tell the customers that they never close to the discharge place and the fire is
forbidden.
·Take apart the pipe by cutter.
Never take apart the part by soldering, otherwise it will fire the rest refrigerant in the
systems and cause blast.
·Exhaust the rest refrigerant in the systems before welding.
·After filling the refrigerant the sealing should be done by using smithing welding
nozzle.
Using the welding machine will fire the refrigerant and blast.
·Since the R600a is heavier than the air, please let the R600a on the ground go
especially for the hypogeum.
·The operation on the servicing refrigerant bottle should be done in place without fire
and outdoors.
·Use the refrigerant warner please， as the rest refrigerant will cause the fire.
·Don’t use fire in the place with rest refrigerant.
·Don’t place the default compressor in indoor.

Danger
·During repairing, the power plug should be disconnected.
Before remove, install, replace parts disconnect the power plug.
·Attention don’t get electric shock.
When checking current, voltage or charging never touch the connectors.
When changing the parts, don’t touch the charged parts within three minutes after
disconnect the plug.
The capacitor will discharge for some time.
·Don’t damage the cooling pipe, sine the refrigerant is flammable, the damage will
cause the fire or blast.
·Don’t smoking in the service car.
·Discharge the refrigerant entirely in the place without fire before disusing the
refrigerant bottle.
·Don’t touch the wine cooler when the cooling pipe damaged, don’t fie inside the wine
cooler, keep the windows open to exchange the air.
·Disusing the default compressor should be done outdoor without fire.
·The maximum weight of the refrigerant bottle loaded in the vehicle should be comply
to stated, the bottle should be place upright, the maximum leaning angle is 40°.
·Do use the appointed part, otherwise it have chance to smoke fire or default.
·Please put the default compressor into plastic bag and seal the peristome, then pack
it with strip, as the rest compressor oil may leak in the vehicle and cause fire or blast.
·Check if all the snails, parts, wiring are install in it’s place, if the area around the
service part worsen.
When measuring the grounding resistance make sure that the test range is more than

5
/
23
1MΩ.
Make sure the power cord and plug never be pinched on rear of the wine cooler.
Exchange the power cord when it damaged.
Clean the flake of the plug when it dirty.
Notice
·Attention the hot.
The running or just stop compressor and the pipe sometimes are very hot. And the
heating or just stop heater is very hot. The hot will cause scald.
·Attention the hot parts of the pipe after the welding.
·Attention the refrigerant during charge and discharge it, as it will frostbite the skin
when touch it.
·Attention the burr.
The burr on the metal or plastic part may hurt the hand.
·Attention the fins of the evaporator.
The fins of the evaporator may hurt the hand.
·Drive up the wine cooler when moving it. Pushing it may damage the floor. Cover a
protector board on the easy damage floor.

4. Name and function on control panel.
•“ ” Press ‘▲’，the setting temp will raise up in 1.
•
•“ ” Press ‘▼’，the setting temp will lower down in 1.
•
•“”Press one time, the light on, press again, the light off, it is not effect by the door switch. Press it and hold on
for three seconds will enter the time adjustment. Press ‘▲’ adjust the hour, press ’▼’ adjust the minute.
•“”Press it one time, the power on, press it and hold on for three seconds, the power off.
•“Power” Power on/off indication light.
zThe default setting temp of this wine cooler is 12, but when restart the wine cooler after power off, it will
back to the former setting temp before power off.
zAccording to customers’ requirement, this wine cooler can be set to that the readout display actual temp or
setting temp.
a.In the readout display actual temp mode, press the ‘▲’ or ‘▼’, the systems enter the temperature setting
mode and the setting temperature twinkling. Five seconds twinkling after stopping adjust temperature, the
readout stop twinkling and the readout show actual temperature, the temperature setting mode end.

b. In the readout display setting temp mode, press the ‘▲’ or ‘▼’, the systems enter the temperature setting
mode and the setting temperature twinkling. Five seconds twinkling after stopping adjust temperature,
the readout stop twinkling and the readout show setting temperature, the temperature setting mode end.
5. How to diagnose the fault.
5.1 Fault finding by the self-check mode.
The wine cooler is controlled by computer, in order to maintain the wine cooler easily, there is a self-check
function in the control PCB.
If you suspect that the control system fault, you can star the self-check mode by following below:
1 >．Power on the wine cooler, it will beep one sound, the wine cooler star, within 10 seconds after it star, press
the ‘▲’and‘▼’at the same time and holding, three beep will sound, the systems enter self-check mode.
The power indication light is on.
The readout show the actual temp.
The inner fan running.
No response when press the controlled buttons.
2>．If all items tally with above description, the parts are normal. If any part fail, check the failed part and the
corresponding wiring and connection, if the wiring and connection is in good condition, replace the part and
check again, if it still failed, the default should be the control PCB, replace it with same model. ( →6.2.1)( →
6.2.2)
3 >．The self-check can be quit only disconnect the power plug.
