Buying a new refrigerator Bosch is always an event that marks the beginning of comfortable operation of high-class equipment. However, the joy of the purchase can be overshadowed if you ignore the key stages of the initial preparation of the equipment. Many users make the mistake of plugging the unit into the network immediately after delivery, which can lead to serious damage to the compressor.
Modern models, whether Series 4 or premium series VitaFreshrequire strict rules of transportation and acclimatization. Incorrect starting can void the manufacturer's warranty, since service centers can easily determine violation of operating conditions by the state of the refrigerant and oil in the system.
In this article we will look in detail at how to start a Bosch refrigerator so that it can serve for decades without failure. You will learn about settling time intervals, installation nuances and initial adjustment of temperature conditions for various chambers.
Primary preparation and settling time
The most critical stage is the period between unpacking and the first connection to the power grid. During transportation, especially if the refrigerator was transported in a horizontal position or at an angle, compressor oil it could flow into the cooling system circuits. If you turn on the unit immediately, the compressor will work “dry”, which will lead to its rapid wear or jamming.
The time required for the oil to drain back into the compressor crankcase directly depends on how exactly the delivery was carried out. If the equipment was transported strictly vertically, without strong shaking, 2-3 hours is enough. In case of horizontal transportation or strong tilts (more than 40 degrees), the waiting time increases.
⚠️ Attention: Never try to speed up the oil drainage process by tilting the refrigerator in different directions after installation. This can lead to blockage of the capillary tube and failure of the system.
For models with inverter compressors, which the brand is famous for Bosch, the requirements for oil purity are even higher. Tiny drops of liquid entering the compression chamber can cause water hammer. Therefore, experts recommend keeping the equipment at room temperature for at least 4-6 hours after winter delivery in order to warm up and stabilize.
Installation and alignment of the case
Before thinking about how to put the Bosch refrigerator into operation, you need to provide it with ideal placement conditions. The unit should not be placed close to a wall or furniture. The rear condenser grille requires free air flow for efficient heat exchange. The minimum gap from the back wall to the wall of the room should be 5-7 cm.
It is extremely important to ensure horizontal installation. An uneven floor or a skewed housing will cause the doors to open spontaneously or, conversely, not close tightly. This will break the tightness of the chamber and force the compressor to work in increased mode, consuming excess electricity.
Height adjustment is carried out using the front support legs. To do this, use a wrench or an adjusting lever, which is often included in the kit. By rotating the legs, achieve a position in which the body is stable, and the door, when opened 45 degrees, tends to return to the closed position under the influence of gravity.
☑️ Checking the installation
Hygienic treatment before use
The interior of the new refrigerator may have a specific technical smell of plastic and packaging materials. To prevent food from absorbing these aromas, it is necessary to thoroughly sanitize all surfaces before loading food.
For washing, use a soft sponge and a weak solution of baking soda or a special product for cleaning refrigerators. It is strictly forbidden to use abrasive powders, aggressive solvents or chlorine-containing substances, as they can damage the antibacterial coating of the shelves and the internal enamel.
- 🧼 Thoroughly wash all removable shelves, drawers VarioBox and egg containers with warm water and soap.
- 🌬️ Wipe the inner walls of the chamber with a damp cloth, paying attention to the corners and seals.
- 🚪 Leave the doors open for 1-2 hours to completely remove the smell and dry the internal surfaces.
Pay special attention to the rubber seals on doors. They also need to be wiped, removing factory grease or dust. A clean seal provides better sealing, which is critical for the energy efficiency of the device.
First switching on and setup diagram
After the refrigerator has settled and been washed, you can proceed to the actual start-up. Plug the power cord into a separate, properly grounded outlet. Avoid using extension cords and tees, as the compressor starting currents can be high.
Immediately after being plugged in, some models Bosch may emit an audible signal or light up alarm indicators. This is normal - the system signals that the temperature inside the chambers has not yet reached the set values. After a while, when the unit gets cold, the signals will stop.
The temperature mode is adjusted through the control panel, which, depending on the model, can be located on the outside of the door or inside the chamber. For initial start-up, it is recommended to set the standard values, and then adjust them to suit your needs.
What does the flashing Super indicator mean?
If the Super indicator is flashing, it means that the super cooling function is active, but the temperature has not yet been reached. If it lights up constantly, it is possible that the door is open or the temperature in the chamber is higher than normal.
The table below shows the recommended factory settings for various types of cameras that should be set when starting for the first time:
| Camera type | Recommended temperature | Purpose |
|---|---|---|
| Main chamber | +4°C... +5°C | Storage of prepared meals, dairy products |
| Fresh zone (VitaFresh) | 0°C... +2°C | Raw meat, fish, vegetables, herbs |
| Freezer compartment | -18°C... -20°C | Long-term storage of frozen foods |
| Shelf for bottles | +2°C... +4°C | Cooling drinks |
Operation control on the first day
First 24 operating hours are test hours for new equipment. During this period, it is not recommended to completely load the refrigerator with food. It is better to put in a minimum amount of food or run it empty so that the system reaches operating mode without unnecessary heat load.
Listen carefully to the operation of the compressor. Modern refrigerators Bosch operate very quietly, but you can hear the gurgling of refrigerant, clicking of the thermostat or the noise of system fans. NoFrost. These sounds are signs of normal operation and not a defect.
Check the heating of the side walls of the case. In some models, condensation pipes are built into the sides, so they can become noticeably hot (up to 40-50°C). This is the normal mode of heat removal, and there is nothing to worry about if the heating is uniform.
⚠️ Attention: If you smell a burning smell, hear a loud knock or vibration radiating to the floor, immediately unplug the device from the network and contact an authorized service center.
Typical startup errors
Even careful study of the instructions does not always save you from human errors. One of the most common is to install the refrigerator next to it, such as a radiator, oven, or in direct sunlight. This forces the cooling system to work at its limit.
Another common mistake is setting the minimum possible temperature immediately after turning on. Sharp start at maximum power (SuperFrost or SuperCool) without a smooth transition to the mode can create excess pressure in the system. Use these functions only for quick freezing or cooling, not for initial startup.
- ❌ Loading with warm food: Never put hot food in a new refrigerator; this will upset the temperature balance.
- ❌ Ignoring packaging: Make sure all shipping tapes, foam inserts and protective films are removed inside and out.
- ❌ Incorrect socket: Connecting to an ungrounded socket can lead to a build-up of static electricity and incorrect operation of electronics.
Remember that electronic control module is sensitive to voltage changes. If surges frequently occur in your network, it is recommended to use a voltage stabilizer or surge protector with protection.
Frequently asked questions (FAQ)
How long can you not turn on a Bosch refrigerator after purchase?
The minimum settling time is 2-3 hours if transportation was vertical. If the refrigerator has been sitting, you need to wait 6 to 12 hours for the oil to completely drain into the compressor.
Why does the refrigerator make a loud noise when you first turn it on?
The noise can be caused by the operation of the NoFrost system fans or the circulation of the refrigerant. If the noise is not accompanied by body vibration and knocking, this is normal. Let the equipment work for a day to adapt.
Do you need to wash a new refrigerator before use?
Yes, definitely. Particles of factory dust and the smell of plastic and packaging may remain inside. Wipe the chambers with a soda solution or mild detergent and let dry.
What to do if the door does not fit tightly after installation?
Most likely, the refrigerator is installed at an angle. Adjust the height of the front legs so that the body is strictly level, and the door has a slight tilt back for self-closing.
