1.Product Features
1.1 Mr.frozen use latest high performance DC compressor with excellent cooling
performance, lower noise and small vibration. The cabinet is super thickness foaming
insulation which is featuring excellent heat preservation and energy saving.
1.2 Microcomputer precise temperature control and indicate the temperature
accurately inside. Easy to operate by pressing the button.
1.3 The compressor is the frequency conversion type. There are two options, one is
Max mode that the compressor running in full speed, the other is Eco mode that the
compressor running economically.
1.4 The freezers can be supplied by DC 12V/24V power source directly
1.5 The device is equipped with a three-lever battery voltage button (H/M/L) that
protects your battery against excessive discharging when the device is connected to
the battery in the solar power system or the battery alone. Generally buyer is
suggested to set H when there is much power supply, and set L when the power
supply is less.

Note: 1. Before connecting the unit to the power source, let it stand upright for approximately 2
hours. This will reduce the possibility of a malfunction in the cooling system from handling during
transportation.
2. It is recommended to store the contents after the cabinet temperature below 0.
Defrost
Water vapor may ice on the inner cabinet. This will reduce the cooling performance of the fridge.
It is necessary to defrost the freezer when the frost layer reaching to 5-7mm. Please follow up the
steps as below.
1. Freezing the content at the lowest temperature for a period to prevent from melting during the
power-off time.
2.Power off the freezer and take out of the content, then try to prevent from melting the content.
3.Open the door, and wipe off the frost layer when it is melting.
4.Dry the cabinet with a clean towel. Power on the freezer and take back the content.
Note: Don’t use sharp items to defrost in order to avoid damaging the evaporator.
5.Trouble Shooting
1.No cooling
function
If the voltage is normal?
If the power cord connect well?
If the adaptor connect well?
Max：quick freezing mode
Eco: power saving mode
Press
Press to switch between Max. and Eco
Cut-off voltage setting
Press UVP button to switch
between H\M\L.

2.cooling effect is
bad
If the product exposed to the sunlight or very close to heat source?
If the compressor or condenser covered with dust?
If the content inside of the product too much or there is hot content inside?
3.Non-stop for a
long time
If the door seal is not good enough?
If there is too much frost inside?
If the ambient temperature is too high.
If too much hot things put inside of the product.
4.Big noise from
the product
If the floor is even and stable?If the product install evenly.
If the back of the freezer very close to the wall.
5.Error indication
Err0:malfuntion of temperature sensor.
Err1:over voltage or under voltage.
Err2:big current on cooling fan.
Err3:bad heat dissipation and lock-rotor of compressor.
The following issues are not trouble.
5.1. Sometimes there is frost on the surface of fridge caused by high
ambient temperature or infrequent door opening. Buyers can wipe the frost off.
5.2. There is sound of water flow or water boiling which is the sound of
refrigerant flowing normally.
5.3. When the freezer is working, compressor and condenser will heat,
these are normal phenomenon.
5.4 The compressor will be working for a long time when storing too
much food over heat.
5.5 The compressor will be working for a long time to keep the inner cabinet temperature when
the ambient temperature is very high.
Notice：When the freezer got problems, please check by this manual first. If the problems still
can not be resolved, please contact distributor or local service counter. Please do not disassemble
without expert guide.
6.Knowledge of usage
*Keep appropriate gap between stored items is conducive to the
circulation of cold air and heat exchange the cooling performance
will be better
*Always cool the food or drink before storing them into the freezer.,
*The freezer reboot after 5 minutes power-off time is necessary, otherwise it will affect the life of
the compressor, or even damage the compressor.
*Do not open the door more than necessary and longer to save
energy
*According to the needs of storage items to choose the appropriate
temperature unnecessary freezing will cause power waste.
*The temperature can be set lower before the expected black out, then the compressor accordingly

working longer, meantime reduce the times of opening and closing freezer doors. Please avoid to
open and close freezer doors frequently as well as put into more content during black-out period.
7.Clean and maintenance
*Clean the freezer with a soft cloth moistened with lukewarm water.
*Never use solvents or abrasive cleaners as this will damage the freezer Do not use scourers or
scrapers to clean your freezer.
*Use a soft dry cloth to completely dry the freezer after cleaning.
*If the refrigerator is to be long-term disable should cut off the power
and clean , open the door a few days in order to maintain internal dry.
*Pay attention that no water drops into the vents as this maybe lead
to damage to the electric components.
* Check the following items after maintenance:
1. If the DC plug is well positioned on the socket.
2. If the DC plug is with over heat.
3. If the DC power cord is with crack or scratch.
