Never let the refrigerator share the common socket with other appliance,
otherwise the cable becomes hot and fire might be resulted.
Protect cables
Never break or damage the cables otherwise current leakage and fire might
be resulted.

allowed, otherwise fire might be resulted
After power break
After power break or unplugging the refrigerator, always wail at least 5 minutes
and then you may plug the refrigerator and start it again.
No medicine
No medicine is allowed to keep inside the refrigerator.

Use and Caution
1. Before use:
Plug the refrigerator on 220-240V~ exclusive socket.
After the refrigerator running,put hand on the air suction to confirm it is suf-
ficient cold. Then you may put food inside the cold box.
2. Digital Temperature controller
Refrigereant LED Defrost LED
Features Of Function
It is a mini-sized and integrated intelligent controller and applicable to the
compressor of one Hp.
The main functions are:Temperature Display/Temperature Control/
Manual,automatic defrost by burning off/Illumination Control/Value Storing/
self Testing/parameter Locking
Front Panel Operation
1. Set temperature
• Press „set“ button, the set temperature is displayed.
• Press or button to modify and store the displayed value.
• Press „set“ button to exit the adjustment and display the cold-room tem-
perature.
2. If no more button is pressed within 10 seconds, the cold-room temperature
will be displayed.
3. Illumination: Press button, it lights; Press again, it stops.
• Manual start/stop defrost:Press button and hold for 6 seconds to defrost or
stop defrost.
4. Refrigerant LED: During refrigeration, the LED is on; When the cold room temp.
is constant, the LED is off; During the delay start, the LED flashes.
5. Defrost LED: during defrosting, the LED is on; When is stops defrosting, the
LED is off, During the delay display of defrost, the LED flashes.
6. Digital controller reset
• When display shows "Disorder", press button for 2s until buzzer rings,
quickly press button for 6s until buzzer rings again, the display will flash
for 3s and it restores factory setting.

3. Cautions
• Shorten the door open time and reduce open frequency is good to keep
a cold temperature inside the refrigerator.
• Never block the air suction and outlet. Keep air circulation and refrigeration
capability.
• Do not make food congested as it will influence the cooling effect. Adjust
the rack height for proper food storage.
• Cool the hot food down to room temperature before you put it into the
refrigerator.
• Try to reduce the open times and keep refrigerator inside cold in case the
power is cut off.
• Only skilled service man is allowed to repair the damaged power cable with
special tools.
• Never touch compressor to avoid from scald.
• This appliance is not intended for use by persons (including children) with
reduced physical, sensory or mental capabilities, or lack of experience and
knowledge, unless they have been given supervision or instruction concern-
ing use of the appliance by a person responsible for their safety.
• Children should be supervised to ensure that they do not play with the
appliance.
• The operation manual are not suitable for the persons (including children)
with reduced physical, sensory or mental capabilities,or lack of experience
and knowledge.
• Do not store explosive substances such as aerosol cans with a flammable
propellant in this appliance.

• Often keep the refrigerator clean and periodical maintenance is necessary.
• Always unplug the socket before maintenance
• Never use damaged plug or loose socket to prevent from electric shock or
short circuit.
• Never flush the refrigerator. Never use alkali detergent, soap, gasoline, ac-
etone or brush.
2. Clean outside
• Dip soft cloth in neutral detergent(tableware detergent) to clean the outside
of the refrigerator and then wipe it with dry soft cloth.
3. Clean inside
• Take rack out for cleaning with water
4. Shut down refrigerator for a long time
• Take all food out and unplug the wall socket.

Trouble Shooting
Trouble Cause and Remedy
No refrigeration • Is the plug in socket well?
• Is the fuse broken?
• Is there no power?
Unsatisfactory refrigeration • Is it under the sunshine?Is there any heat
source nearby?
• Is the surrounding ventilation bad?
• Does the door close well?Does door open
for a long time?
• Is the door seal strip deformed or dam-
aged?
• Is food congested or too much?
• Does food block the air suction or outlet?
• Regulate the temperature controller.
Dużo hałasu • The refrigerator does not level.
• The refrigerator contacts wall or other
matter.
• There is loose part in refrigerator.
Contact local service agent for help if simple trouble shooting does not solve
the problems.
Note
Following phenomena are not troubles
The murmur of water is heard when the refrigerator is working. It is a normal
phenomenon as the coolant is circulating in the system.
In wet season, condensation might be found on the outside of the refrigera-
tor. It is not a trouble, which is caused by high humidity. Simply use cloth to
wipe it.

Principle of Refrigeration System
The principle of compression refrigeration consists of “compression”, “con-
densation”, “throttling” and “vaporization”. The compression is undertaken by
compressor, the condensation is completed by condenser, the throttling valve
is executed by capillary and the vaporization is implemented by evaporator.
When the coolant is circulating in the closed refrigeration system, the compres-
sor sucks coolant, which has absorbs heat in evaporator, the coolant becomes
a high pressure and high temperature gas. In condenser, it dissipates heat in
air, while the coolant is re-liquefied and throttled in capillary and then enters
into evaporator with low pressure. The liquefied coolant quickly boils and
vaporizes into gas when the pressure suddenly drops. Meanwhile, it absorbs
heat inside the refrigerator. And the compressor sucks the low pressure and
low temperature gaseous coolant. It is circulating in this way up to realization
of intended refrigeration.
