3.2 Description of functions and main components

A high-quality DC variable frequency compressor and drive module are used to

provide a high-eﬃciency, energy-saving, stable and reliable mobile refrigeration

system.

Microcomputer intelligent control system, easy to operate, accurate temperature

control.

Compatible with a variety of power inputs, intelligent recognition

of DC 12/24 V which meets the needs of various situations: car, boat, home,

outdoors if required.

With the function of voltage detection and low-voltage protection, it can eﬀectively

prevent the car battery from over-discharging. The inner container is made of high-

Operation of the cool box

4.1 Precautions for use

When using the cool box, please put it in a well-ventilated place which is conducive

to heat dissipation. Especially, the gap between the cooling hole on the compressor

side and other objects must be greater than 100 mm, so as to prevent high

temperature from causing failure or aﬀecting the refrigeration eﬀect.

Please do not leave the door open for a long time, as the temperature diﬀerence

between the inside and outside of the cool box will be too great and frosting will

aﬀect the refrigeration eﬀect.

Do not clean the cool box under tap water.

Do not use the cool box near a heat source, as it will reduce the refrigeration

performance of the cool box.

Please do not use the cool box on a steep slope for a long time. This may aﬀect the

service life of the cool box and reduce the refrigeration eﬃciency.

4.2 Precautionary measures for basic use

Temperature control range: -20℃~+10℃

Temperature display range: -30℃~40℃

Standard voltage input range: DC12V / 24V, no more than maximum DC30V

4.3 Functional description

4.3.1 Switching on and connecting the cool box

Connect the correct DC12 / 24 V power supply. If the cool box is in standby mode, press

and hold the on/off key for 2 seconds to complete the startup. After startup, the display will

normally show the current temperature and working mode of the incubator. After the

startup delay (1 minute factory preset), the cool box will operate in working mode and the

compressor will start to refrigerate.

4.3.2 Cool box keypad locking and unlocking

If the keypad is locked (the child lock icon in the lower right corner of the display is on),

press and hold the "up / down" key for 3 seconds at the same time to release the lock. If

the child lock system does not light up and there is no operation for 20 seconds, the keypad

will automatically be locked.

4.3.3 Cool box temperature setting

When the keypad is unlocked, press the “up/down” key to adjust the temperature of the

cool box (a group of temperature values on the display will flash to show the current set

value). Each time you press the key, the temperature rises or falls by 1 degree. If you hold

the key, you can quickly adjust to the required temperature value. If there is no change

within 5 seconds, the setting value will be saved automatically.

4.3.4 Setting the compressor operating mode

If the keypad is unlocked, press the “set” button to freely select the “Eco / Max” compressor

operating mode. If you need to quickly cool to a lower temperature, switch to the "Max"

mode. If you only need to refrigerate or keep warm, you can set to the "Eco" mode to save

energy and power.

4.3.5 Setting the low-voltage protection function

This product has the function of low voltage protection. If it detects that the battery voltage

is lower than the set value, it will automatically turn oﬀ the compressor to prevent over-

discharging from damaging the battery or not allowing the car to start normally. At this

time, the display screen will display "E1" code prompt. If the voltage returns to normal, the

cool box will automatically enter the operating state one minute later. The factory default is

"medium". If you need to change it, please follow the following steps:

a: Unlock keyboard

b: Keep the “SET” key depressed for 6 seconds, release it after hearing the beep of the

buzzer, and then press the “SET” key briefly. At this point, one of the battery protection

level icons, “L, M or H”, will flash on the display. Then press the

“up/down" key to change the setting. Speciﬁc value

If your cool box enters the battery protection mode prematurely, it is likely

that your power supply voltage is insuﬃcient and the low-voltage protection

value is set too high. Or the wiring of your DC power supply is not suitable and cannot

provide enough power. Check whether the power supply wiring is suitable, and consider

appropriately lowering the battery protection grade. In order to ensure that the car can

start normally, it is recommended to set the protection level at “H” when using the cool box

in the car.

4.4 Cleaning and maintenance

Before cleaning, it is necessary to disconnect the power supply and wipe the inner and outer

surfaces of the cool box with a cleaning cloth dipped in an appropriate amount of water or

detergent. It is not allowed to wash directly with water to avoid damaging the electrical

components.

If the cool box is not used for a long time, the inside and outside must be cleaned and kept

dry, and measures must be taken to protect it against moisture and dust, and to prevent

mould formation and unusual odours inside the cool box.

4.5 Error code description

If the compressor, module, fan or temperature measuring head are working abnormally and

the input voltage is too low, the error code will appear on the display screen, and the

compressor will stop working. Once the abnormality has been rectified, unplug the power

supply and plug it in again to return to the temperature display in the box; the cooling

mode of the compressor will start working after 1 minute.

FAQ

If the product does not work properly:

Check whether the power is on

Check whether the voltage is too low

Check all connections from battery to cool box for looseness or poor contact

Check the fuse

Check whether the cool box is turned on; check if the temperature is set too high

If the cooling efficiency is poor:

It may be that too much food has been packed in the cool box

The temperature of the food in the cool box is too high. Check whether:

oThe lid is not closed correctly

oThe lid seal (sealing ring) is not damaged

oThere is good ventilation around the cool box

oThe ambient temperature is not too high

oThe temperature setting is correct

I can hear the sound of “water ﬂowing” in the cool box

This is normal. It is caused by the ﬂow of refrigerant

When the cool box starts up, the sound is loud

If the cool box is placed with the compressor side on a ﬂat horizontal surface, check

the surrounding objects for vibrations

When the compressor is started, when the motor changes from static to high speed,

the sound will be slightly louder. Once the speed is stable, the sound will decrease,

which is a normal phenomenon

There are water drops around the housing or door seal

It is normal for moisture in humid air to liquefy and condense water droplets when it

comes into contact with a lower temperature shell
