3. Safety Cautions
1.This unit uses AC220~240V/50Hz or AC110V-120V/60Hz power,
there should be a 500va stabilizer if the voltage luctuation exceed
AC187～242V or 98V-127V/60Hz respectively.
2.The user should hold the plug when the power is on/off, dragging or
pulling the power cord is prohibited.
3.Do not remove the power cord or plug
4.Must use dependent socket and reliable ground wire. Ground wire
must not connect with the null line of the gas pipe, warm gas pipe,
water pipe and must be single power
5.Never splash water on the unit directly.

2.The unit should be place on a solid and firm ground, take away the
bottom pack to lower
the shock and noise.

3.Leave at least 20 cm of distance between the back of the unit and the
wall for ventilation and leave a space with an open angle of 160 ° for
the door.
4.Keep the unit away from heat sources and avoiding direct sunlight.
5.Never place the unit on a location where water can reach or with high
moisture. Splashed water and dirt should be wiped off in time by

3.After moving the unit, place the unit for 30 minutes before switching
it on. Running: close the door and connect the power, turn on the
lamp switch on the control panel, the lamp is on. Half an hour later,
the temperature inside the case lower apparently, it indicates the unit
on be normally used
4.After connecting the power, the unit should be kept empty for one
hour.
6. Setting and adjustment of temperature
1.Adjust the storage temperature through the temperature controller
located in the internal of the case(see the picture), adjust the
temperature according to the ambient temperature and the foodstuff.
2.See the following picture about the knob scale. The temperature
adjustable capacity is from “1”-“5”, adjust the storage temperature
by turning the temperature controller clockwise. The higher of the
number shows the lower of the storage temperature. The knob can
turn freely but can’t turn clockwise from “5”to “1”. Factory setting
position is on “3”.

3.Check if the scale is on an appropriate position before using, frequent
adjustment is not appropriate when using. Normally in summer, the
ambient temperature is high, anti clockwise turn the knob to “5”,
while in winter, the ambient temperature is low, clockwise turn the
knob to “1”.
4.Position “0” represent stop running.
7. Storage of articles
1.Do not put large amount of articles into the unit at one time, you
should leave some space around the foodstuff to let cold air inside
the cabinet counter to flow. Keep bottled articles away from the
walls of interior cabinet so as not to freeze it until broken.
2.Do not put warm food into the unit directly until they are cooled
under normal temperature, it will facilitate to lower its energy
consumption and prolong service life of the compressor.
