Dear Customer

Dear users (customer), this manual contains the product’s basic knowledge, use instructions, fault diagnosis and basic troubleshooting methods. In order to better understand and use this product, please take good care of this manual and read it carefully.
This equipment is intended for the storage and display of non-time/temperature control for safety foods bottled or canned products only.

Important safety instructions

1. The range of operating voltage is 97V~130V. To avoid damaging the electrical performance of the compressor, please install with a voltage stabilizer appliance of power not less than 500W, to protect the cooler when the voltage is lower than 97V or higher than 130V.

2. An exclusive single-phase socket must be used. It should be reliably connected to a grounding wire. Caution: The grounding wire is not allowed to connect to a water pipe or a gas pipe.

3. Strong base, acid, organic solvents, and corrosive goods that are easy to pollute the food are prohibited from being stored in the cooler. They can cause corrosiveness or accidents.

4. Don’t raise the cooler or the shell of the electric parts, or it will cause a decline in insulation and cause corrosion.

5. When the cooler will be not be used for a long time, disconnect the power and clean it. Please examine the circuit to see whether it is ok before reuse.

6. If the supply cord is damaged, it must be replaced by a special cord or assembly
   available from the manufacturer or its service agent.

7. The appliance shall be disconnected from its power source during cleaning or maintenance and when replacing parts.

8. The A-weighted emission sound pressure level is below 70Db(A).

9. Do not store explosive substances such as aerosol cans with flammable propellants inside the appliance.

10. Flammable blowing gas in the cooler should be handled according to local regulations.
    Before you scrap the appliance, please take off the doors to prevent children from being trapped.

Caution

1. Risk of fire / flammable materials, take care to avoid causing a fire by igniting flammable material.
2. Keep clear of obstruction of all ventilation openings in the appliance enclosure or in the structure for building-in.
3. Do not use mechanical devices or other means to accelerate the defrosting process, other than those recommended by the manufacturer.
4. Do not damage the refrigerant circuit.
5. Do not use electrical appliances inside the food storage compartments of the appliance, unless they are of the type recommended by the manufacturer.
6. The ambient temperature and humidity conditions of the cooler climate class follow the table below:

NOTE: the water vapor mass in dry air is one of the main points influencing the performance and the energy consumption of the coolers. Therefore, the order of the climate class in the table is based on the water vapor mass column.

Transportation and Placement

Transportation

1. Take out packing materials and clean all the cabinets using warm water with 5% neutral soap and then dry it with a soft cloth; for the glass parts only use specific products, avoiding the use of water which can leave limestone residues on the glass.
2. Keep a distance of at least 10 cm from the wall. Please level the unit by settling the adjustable feet.
3. The cabinet must be installed on a perfectly even surface, far away from any heat source including sun rays.
4. Do not install the unit in open places and do not expose it to rain.

Choosing the installation location

The unit is for indoor application only.
Because the unit has a glass door, its performance is highly influenced by environmental conditions. To minimize the environmental effects on the unit’s performance, the following are recommended:

• The unit is not to be placed near any kind of heat source.
• The unit is not to be placed near or inside air streams produced by ventilation fans, open doors and/ or windows.
• The unit is not to be situated under a roof-mounted ventilation system.
• The unit should have sufficient space to ‘breathe’ (always use the rear space to ensure minimum clearance).
• The unit should not be placed under direct sunlight.
• Keep all ventilation openings in the appliance enclosure or in the structure clear of obstruction.
• In order to reduce fire hazards, the installation of this appliance must be carried out only by a suitably qualified person.

Leveling the unit

Place the unit at the chosen location. Using a spirit level, check whether the unit is leveled in both directions.
The spirit level can be placed on one of the shelves.
The unit must be leveled during operation to avoid possible ice formation on the evaporator’s fins due to insufficient drainage of the condensation.
Tilt the unit by a 2° angle for easy closing of the door and drain.

• Do not insert cream or spray bottles inside the cooler.
• Do not store explosive substances such as aerosol cans with flammable propellants in the cooler.

Product Features

1. It uses a quality, effective, and hermetic compressor with broad range of starting voltage, suitable ambient temperature: not higher than 40℃, and reasonable matching of the cooler system that guarantees its powerful refrigerating ability and energy saving.
2. Goods stored can be displayed clearly through the door made of luxurious hollow glass.
3. The thermal insulation layer of the cooler made from hard polyurethane foamed plastics makes it light and has a good ability to keep the contents cold.

Electrical Connection

Electronic diagram

WARNING

1. Do not, under any circumstances, cut or remove the third (ground) prong from the power cord supplied.
   This appliance is not designed to be used with an inverter.
   The cord should be secured behind the appliance and not left exposed or dangling to prevent accidental injury.

2. Never unplug the cooler by pulling the power cord. Always grip the plug firmly and pull straight out from the receptacle.

3. Do not use an extension cord with this appliance. If the power cord is too short, have a qualified electrician or service technician install an outlet near the appliance. Use of an extension cord can negatively affect the performance of the unit.

4.  Improper use of the grounded plug can result in the risk of electrical shock. If the power cord is damaged, have it replaced by an authorized service center.

Safety Warnings

• Warning! Do not damage the cooling fluid circuit.
• Warning! Do not damage the walls of the machine: the cooling fluid circuit may be damaged.
• Warning! Do not use electrical appliances inside the food storage compartments of the appliance, unless they are of the type recommended by the manufacturer.
• Warning! The equipment must not be used by persons (including children) whose physical, sensorial, or mental capacities are reduced, or who lack experience and know-how, unless
  they have been provided, by means of a person responsible for their safety, with suitable monitoring or instructions about the use of the equipment. Children must be monitored to ensure they do not play with the equipment.

Use warnings

1. Unpack all packages before using the cooler. Do not tilt it over more than 60°, while moving it.
2. In its initial operation, the cooler should run emptily for about two hours before storing food in it. 3. The thermostat can adjust the temperature inside the cooler. When you turn the knob
3. clockwise, the bigger the number, the lower the temperature. Generally, the positions ‘3-4’ are suitable for regular operation. The ’6’ position has the appliance operating continually.
4. To save energy, the door should not be opened too frequently or left open for a long time.
5. The surface and the inside of the cooler should be dry and clean. Long-term moisture will cause the cooler to slowly rust. (There will be some stains on the surface.)
6. Periodical cleaning is suggested. Generally, cleaning the appliance once every 30-45 days is the best. When cleaning, it is best to wipe the inside and the surface of the cooler with a soft cloth with neutral soap or detergent.
7. Caution: To ensure safety, the power plug must be pulled out before cleaning.

Cleaning the unit

For cleaning the unit’s internal plastic parts, use a light solution of soap and water. Do not apply hard chemical detergents on the plastics as they may lose their shine or even get deformed.
The same applies to the external metallic surfaces. The use of hard chemicals could harm the painting of the metallic surfaces, affecting the sanitary protection of the unit.
