Introductory information about startup equipment
Purchasing new refrigeration equipment is always a joyful event, marking the beginning of comfortable use in the kitchen. However, before loading the products, it is necessary to correctly perform the initial startup of the device to avoid damage to the compressor and other systems. Modern models of the German brand Bosch equipped with sophisticated electronics and reliable compressors that require careful attention during the first hours of operation.
Many users make the mistake of plugging the device into the network immediately after unpacking or bringing it into the apartment from the cold. This can lead to serious consequences for the refrigeration unit. In this article, we will analyze in detail all stages of preparation, from checking the transportation bolts to setting the optimal temperature conditions, so that your fridge refrigerator will serve for many years without failure.
Compliance with the rules for the first start-up is especially important for models with a system NoFrost and inverter compressors. Incorrect actions may void the manufacturer's warranty, so it is important to follow the algorithm specified in the technical documentation and verified by experts at service centers.
⚠️ Attention: If the refrigerator was transported at a temperature below +5°C, do not plug it in immediately. Leave the device in a warm room for at least 4-5 hours to acclimatize and evaporate condensation inside the electronics.
Preparation after transportation and unpacking
The first step after delivering the equipment home is a thorough visual inspection and removal of all shipping elements. The factory packaging protects the case from scratches and dents, but internal latches may block the operation of the moving mechanisms. Carefully examine the interior of the chambers and the rear wall of the device.
Particular attention should be paid to the compressor, which is often secured with special transport bolts or brackets. If they are not removed, vibration from engine operation will be transmitted to the housing, causing excessive noise and potential destruction of the engine mount. It is also necessary to remove all adhesive tapes from the internal shelves and door seals.
☑️ Check before turning on
After removing the latches, wipe the internal chambers with a damp cloth and a mild detergent. This will remove the smell of “new plastic” and factory dust. The doors must be left open for ventilation for at least 2-3 hours before connecting to the power supply.
The choice of installation location and ventilation requirements
The correct operation of refrigeration equipment directly depends on the conditions of its placement. To effectively remove the heat generated by the capacitor, it is necessary to ensure free circulation of air around the housing. The distance from the back wall to the wall of the room should be at least 5-7 centimeters.
It is not recommended to install equipment in close proximity to heat sources such as radiators, ovens or direct sunlight. An increased ambient temperature causes the compressor to work harder, which increases energy consumption and reduces the life of the refrigerant refrigerant.
Make sure that the floor under the refrigerator is level and stable. Uneven installation will lead to misalignment of doors, failure of seals and, as a result, to the formation of ice or insufficient cooling of products. The height can be adjusted using the front support legs.
Why can’t you place the refrigerator in a niche without ventilation?
Built-in models have a special ventilation system, while freestanding models require clearance on all sides. If you place an ordinary refrigerator in a tight niche, the heat will not be removed, the compressor will overheat and the thermal protection will work or the motor will fail.
First connection to the electrical network
After the device has settled and dried, you can begin the electrical connection. Use only a working, grounded outlet that meets the wattage requirements. It is not recommended to use extension cords or tees, as they can cause poor contact and overheating of the wiring.
When the refrigerator is plugged in, it may make a short sound or click - this is normal, the start relay is activated. Some models with digital control may require a few seconds to initialize the system, after which the indicators on the display will light up.
| Parameter | Standard value | Tolerable deviation |
|---|---|---|
| Main voltage | 220-230 V | ± 10% |
| Current frequency | 50 Hz | ± 1 Hz |
| Room temperature | +16...+32°C | According climate class |
If an alarm indicator lights up on the control panel or a beep sounds, do not panic. This is a standard reaction to an increase in temperature inside the chambers after a long period of inactivity. The signal usually turns off automatically after a few hours of operation or manually with a button Alarm Off.
Setting the temperature mode
Immediately after switching on, you should not load the refrigerator with food. Let the equipment run idle for about 2-4 hours so that the temperature background in all chambers stabilizes. For models with mechanical control, set the regulator to the middle position, usually number 3 or 4.
Electronic models Bosch allow you to set the exact temperature for the refrigerator and freezer compartments separately. The optimal value for the main compartment is considered to be from +3 to +5°C, and for the freezer - -18°C and below. Lower temperatures increase the load on the compressor without significant storage benefit.
If you activate the Quick Freeze SuperFrost or Super Cool SuperCoolfunction, the system will operate at maximum power for a limited time. After these modes are automatically turned off (usually after 24-65 hours), the refrigerator will return to the specified settings.
Loading of products and operating modes
When the temperature has reached the set values, you can start loading. Do not fill the chambers completely on the first day - cold air needs space to circulate. Place foods evenly, leaving gaps between them and the walls.
It is strictly prohibited to place hot or warm foods inside. This causes a sharp rise in temperature, condensation and causes the compressor to work overload. All products should be at room temperature or chilled.
Modern refrigerators Bosch are often equipped with a freshness zone VitaFreshwhere a special microclimate is maintained for meat, fish or vegetables. For these zones, separate boxes with controlled humidity are provided, which can significantly increase the shelf life of products without freezing.
⚠️ Attention: Do not block the ventilation holes inside the chambers with products. Impaired air circulation will lead to uneven cooling and the appearance of “warm zones” where food spoils faster.
Diagnostics of possible problems during startup
During the first startup, users may encounter phenomena that seem to be malfunctions, but are not. For example, heating the side walls of the case is a normal process of heat removal through the condenser built into the side walls.
Gurgling or hissing of the refrigerant in the tubes may also be observed. This is the sound of freon circulation, which becomes audible especially clearly in silence. If the noise is not accompanied by vibration or knocking, technical intervention is not required.
However, if you notice the following signs, you should contact a service center:
- ❌ The compressor hums, but does not start, or starts and immediately stalls.
- ❌ A “snow coat” forms on the back wall of the refrigerator when it is turned on NoFrost.
- ❌ A persistent smell of burning or melted plastic has appeared.
- ❌ The indicators on the panel blink in emergency mode for more than 24 hours.
Frequently asked questions (FAQ)
How long can you not turn on a Bosch refrigerator after delivery?
If transportation was carried out in a vertical position, it is enough to wait 2-3 hours for the oil in the compressor to stabilize. If the refrigerator was lying on its side, the waiting time increases to 4-6 hours, and if there was sub-zero temperature outside - up to 8-12 hours.
Why does a Bosch refrigerator make clicking noises when operating?
Clicks can be made by thermostats, compressor turn-on relays, or expanding/contracting plastic of the internal housing when the temperature changes. This is the normal operation of automation and materials and does not require repairs.
Is it necessary to defrost a Bosch NoFrost refrigerator?
The system NoFrost automatically removes moisture, so regular defrosting is not required. However, once a year it is recommended to carry out preventive washing and defrosting for hygienic treatment and removal of odors.
What to do if the red alarm indicator is on?
The red indicator signals an increase in the temperature in the chamber. Check that the door is closed tightly and that the refrigerator is not overloaded with warm food. If after several hours of operation the signal does not disappear, the sensor or defrost system may be faulty.
Is it possible to transport a working refrigerator?
No, you cannot transport a working refrigerator. Before transportation, it must be turned off, defrosted, washed and dried. Moving the device while it is on will damage the compressor and disrupt the pipes.
