Important safety instructions

1. The range of operating voltage: is 97V~130V. To avoid damaging the electrical performance of the compressor, please install 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 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 bases, strong acids, organic solvents, and corrosive goods or those that are easy to pollute food are prohibited from storing in the cooler; otherwise, they can cause corrosion or accidents.
4. Do not rinse 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 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 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 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 following the tab below:

Test room climate class| Dry bulb temperature (⁰F)| Relative Humidity (%)| Dew point (⁰F)| Water vapour mass in dry air (g/kg)
---|---|---|---|---
3| 77| 60| 62.1| 12.0
4| 86| 55| 68.0| 14.8
NOTE: the water vapour mass in dry air is one of the main points influencing the performance and energy consumption of the coolers. Therefore, the order of the climate class in the table is based on the water vapour mass column.

• Warning: Risk of fire / flammable materials

Transportation and Placement Transportation

1. Don’t slant it over more than 45°, while moving it.
2. The cooler needs to stand upright for 4 hours before it is powered on, while the product is transported upside down.

Choosing the installation location

1. This unit is for indoor use only.

• 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.

Installation Instructions

1. Unpack all the packages and clean the cabinet using warm water with 5% of neutral soap and then dry it with a soft cloth. For the glass parts only, use glass-specific products, avoiding the use of water which can leave limestone residues on the glass.
2. Keep a minimum of 10 cm distance from the wall or side cabinet. Please level the unit 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.

Note: product space demand size schematic diagram

Levelling the unit
Place the unit at the chosen location. Using a level, check whether the unit is levelled in both directions.
The spirit level can be placed on one of the shelves.
The unit must be levelled during operation 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.
