General

This product is a type of chilling cabinet, which is our new development of refrigeration combining the advanced technologies from both and abroad on the basis of food cabinet standards and corporate criteria. Its main kits and key components are all good brands, either and streamlined design, the product integrates the actual market demand in structural design, which better cater to the ergonomics requirements of consumers. This series applies mainly to displaying and selling of drinks, dairy products, vegetables and fruits.

Structure and Parts

Handle and Erection

Handle with care Unplug the wall socket first. Never tilt it over 45 degree during handling.	Dry place Always locate the refrigerator at a dry place.
Sufficient space The distance from both sides and back of refrigerator to wall or other substance must not less than 10cm. The refrigeration. capability might be decreased if its surround space is too small to circulate air.	Well ventilation Always locate the refrigerator at a place with fine ventilation. For the first time use, wait for 2 hours after handling and then plug the wall socket and start it.
Far from heat source Never place the refrigerator directly under the sunshine. Never locate it nearby any heat source or heater to prevent it from reducing refrigeration capability.	No heavy load Never put any heavy load on the top of the refrigerator.
No hole making Never make hole on the refrigerator. Never install other matter on the refrigerator.	Stable location To avoid the unexpected noise and vibration, Unpacking and locate the refrigerator on a flat and solid place.

Principle of Refrigeration System

The principle of compression refrigeration consists of “compression”, “condensation”, “throttling”and”vaporization”. The compression is undertaken by compressor, the condensation is completed by condenser. The throttling is executed by capillary and the vaporization is implemented by evaporator. When the coolant is circulating in the closed refrigeration system, the compressor 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 reliquefied 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.

Circuit Diagram

Trouble Shooting

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 refrigerator. It is not a trouble, which is caused by high humidity. Simply use cloth to wipe it.

Preparation and Power Supply

Exclusive power socket Normally, the power supply should be 110-120V,60Hz single phase AC with exclusive single phase three pin receptacle.	No share on socket Never let the refrigerator share the common socket with other appliance, other wise 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.	No water flushing Never give the refrigerator surface a flush otherwise current leakage might be resulted
Prevent from flammables and explosive Never put any flammable or explosive inside the refrigerator such as ether, gasoline, alcohol, adhesive and explosive. Never put dangerous product nearby the refrigerator	No spray To spray the flammables such as paint or coating nearby the refrigerator is not allowed, otherwise fire might be resulted.
After power break After power break or unplugging the refrigerator, always waits 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
