Dear Customer

Dear users (customer), this manual contains the product’s basic knowledge, use instruction, fault diagnosis and basic trouble shooting methods. In order to better understand and use this product, please take good care of this manual and read it carefully.

Important safety instructions

  1. The range of operating voltage: 97V~130V. In order to avoid damaging the electrical performance of the compressor, please equip 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. Individual 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, strong acid, organic solvent and corrosive goods or those are easy to pollute
    to food are prohibited storing in the cooler; otherwise, it can cause corrosiveness or accident.

  4. Don’t raise the cooler or the shell of the electric parts, or it will cause the 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 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 a flammable propellant inside the appliance.

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

Caution:

  1. Risk of fire / flammable materials, taking care to avoid causing a fire by igniting flammable material.

Transportation and Placement

Transportation

  1. Take out packing and clean all the cabinet using warm water together with 5% of neutral soap then dry it with a soft-cloth; for the glass parts only use specific products, avoiding the use of water which can leave on the glass limestone residues.
  2. Keep a distance from the wall of 10 cm at least. Please level the unit by settling the adjustable feet.
  3. Cabinet must be installed on a perfectly even surface, far away from any heat source included sun ray.
  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.
Due to the fact that 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 hazard, 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 levelled in both directions.
  • The spirit level can be placed on one of the shelves.
  • It is essential that the unit is levelled during operation so as to avoid possible ice formation on the evaporator’s fins due to insufficient drainage of the condensates.
  • Tilt unit by 2° angle for easy closing of door and drain.
  • Do not insert cream or spray bottles inside the cooler.
  • Do not store explosive substances such as aerosol cans with flammable propellant 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℃, reasonable matching of the cooler system 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 be light and 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.

Caution for Safety

  • Warning! Do not damage the cooling fluid circuit
  • Warning! Do not damage walls of the machine: the cooling fluid circuit may damage
  • 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 of experience and know-how, unless they have been provide, 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.

Caution for Using

  1. Unpack all packages before using the cooler. Don’t slant it over more than 60°, while moving it.
  2. When initial operation, the cooler should run emptily about two hours before storing food in it.
  3. The thermostat could adjust the temperature inside the cooler. When you turn the knob in clockwise, the bigger the figure, the lower the temperature. Generally, the position of ‘3-4’ is suitable.’6’position will be operating continually.
  4. To save energy, the door should not be frequently opened 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 rust slowly. (There will be some stains on the surface.)
  6. Periodical cleaning is suggested for your reference. Generally, 30-45 days once 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.

Caution: To ensure safety, the power plug must be pulled out before cleaning.

Cleaning of 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 brightness 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, thus affecting the sanitary protection of the unit.
