1 overtemperature alarm mark 2 door opening alarm mark 3 battery status mark 4 cabinet
temperature display 5 mute key 6 set key 7 up key 8 down key 9 print key 10 light on key
It is recommended not to adjust the set temperature at will during normal use.When the alarm
sound prompt needs to be cancelled, you can press the mute button to cancel the sound
prompt, but the alarm indicator light and alarm code will be displayed until the alarm state is
cancelled.If there is special need to adjust, please call the after-sales service number or by
professional maintenance personnel adjust.Adjust the setting temperature at will, which may
cause high temperature (AH) or constant temperature (AL) alarm. At this time, please adjust
the set value of high temperature and low temperature alarm (AH,AL) at the same time.
.4.2 temperature setting
The display screen of the normal temperature cabinet shows the current temperature value in
the box under the condition of electrification. If the set temperature needs to be adjusted
again, for example, the original set temperature is 4℃, and now it needs to be adjusted to 5℃
(the set value is recommended), please follow the following steps:
2 temperature setting
The display screen of the normal temperature cabinet shows the current temperature value in
the box under the condition of electrification. If the set temperature needs to be adjusted
again, for example, the original set temperature is 4℃, and now it needs to be adjusted to 5℃
(the set value is recommended), please follow the following steps:

4.3 overtemperature alarm:
In order to ensure the safety of stored goods in the box, electronic temperature controller has
alarm function.When the room temperature inside temperature is higher than 6 degrees or
below 2 degrees and lasts 10 minutes (alarm delay, prevent to open the door to normal
temperature, such as frequent alarm buzzer alarm, alarm characters on the screen at the
same time and alternating current temperature display (note: high temperature alarm Hi, low
temperature alarm Lo), press the mute key hum closed alarm icon to display (screen).When
the temperature in the box is between the upper and lower limits of the alarm, the alarm
disappears.

When the opening time is more than 1 minute, the door of the control panel will open and the
alarm sign will blink and the buzzer will beep.

Tip: if the user calls out the internal code when adjusting the thermostat, please wait
for 1 minute, and then carry out the operation when the temperature in the cabinet is

displayed again, so as to avoid the failure of the normal temperature cabinet due to the
change of control parameters.
In case of power failure or other faults, the normal cabinet will be temporarily stopped,
and the temperature inside the normal cabinet will rise, and the temperature of the box
may rise from 5℃to more than 15℃within one hour. If the electricity cannot be
received within a short time, the stored goods should be taken out and put into other
normal normal cabinets for storage, so as to avoid damage and loss of the preserved
goods
Do not put items into the normal temperature cabinet that has just been connected to
the power supply. Let the empty container run for a period of time
Store refrigerated items in containers.
When putting in the goods, if the goods have too much moisture or too dry will affect
the change of humidity in the box, the goods had better be sealed and kept;Similarly,
the humidity of the working environment of the normal temperature cabinet will also
affect the change of humidity inside the cabinet, especially if the door is opened too
much and the door body is not closed well.
The storage of goods should not exceed 1/3 of the box capacity each time. After
reaching the set temperature and running normally for 24 hours, the goods with
another 1/3 of the box capacity should be put into storage.
Please be careful not to block the air outlet and suction outlet when putting in the
object.
Do not put items directly in the outlet or suction outlet of the normal temperature
cabinet, otherwise it will affect the air circulation and refrigeration effect of the normal
temperature cabinet
Do not try to open the door in the process of cooling, or it will cause the temperature to
rise.
Due to the inertia of refrigeration, there may be some difference between the display
temperature and the set temperature when the product reaches the set value and
stops Different, this is normal phenomenon.
Note: children are not allowed to play games in the room temperature cabinet.
Do not change the setting temperature frequently within a short period of time, or the
setting effect may not be achieved due to the large inertia of hot and cold;When
putting in the goods, it is necessary to ensure that there is a certain air circulation
space around the box, especially the temperature sensor inside the box (for collecting
the temperature inside the box), otherwise it will affect the stability and accurate
display control of the temperature inside the box!

5. Daily maintenance
During routine maintenance, in order to prevent electric shock or injury, be sure to cut off the
power of the equipment before any repair or maintenance.Make sure that you do not inhale
drugs or aerosols around the device during maintenance, which may endanger your
health.Be sure to wear dry gloves to protect your hands during maintenance.Fingers may be
cut on the edges or corners of the case without gloves.
5.1 clean the cabinet
The room temperature cabinet is cleaned once a month.Regular cleaning can make the
thermostat maintain a new appearance;
Use a dry cloth to wipe off small amounts of dust from the cabinet shell and interior and all
accessories.If the normal temperature cabinet is dirty, clean it with neutral detergent.
After cleaning, clean the detergent with a cloth soaked in water;
Do not pour water on the shell of the room temperature cabinet or keep it indoors, otherwise it
may damage the electrical insulation and lead to failure.
In the rainy season, the surface of the glass door of normal temperature cabinet is prone to
condensation of water vapor, and water will drip in serious cases. Please dry it with a dry
cloth or open the door heating switch when appropriate.Will not affect normal use.
5.2 defrost
The room temperature cabinet is air-cooled and frost-free. There is no need to defrost.Under
the condition of high humidity in summer, there may be condensation at the frame position of
the normal cabinet, which is a normal phenomenon. It is suggested to dry it with a dry cloth.
5.3 maintenance and maintenance
Do not place heavy objects on the door or the top cover at room temperature, so as to avoid
deformation of the door body or the top cover under compression.
Clean and maintain the normal temperature cabinet every once in a while.
Rub the inner and outer surfaces of the cabinet with a warm wet soft cloth.
When dirty dirty is serious, the neuter scour that can use catharsis tableware wipes, the soft
cloth that reoccupy washes clean wipes clean water to be soiled.
Once the normal temperature cabinet is enabled, it is best to use it continuously.

6. After-sales service
Any product may fail. Please timely observe the operation of the normal temperature cabinet
during use. If there is any abnormality, please check and deal with it according to the
following table.If you can't change the situation, please inform our service center in time. We
will serve you wholeheartedly to avoid any loss to you.
The following are not failures:
(1) compressor start, stop, switch parts will give out a slight crash sound.
(2) after opening the door into the hot items, the control system appears high temperature
alarm.Solution: put hot items into the normal temperature cabinet after they are cooled down
naturally, and do not put too many items into the cabinet at one time. After the system runs
steadily, the high temperature and alarm will be lifted automatically.
(3) refrigerant flow in the pipeline issued a slight sound of water.
