Purchasing large household appliances is always an event, but the joy of the purchase can be overshadowed if you ignore the rules for the initial launch. Many owners make the mistake of connecting the unit to the power supply immediately after unpacking, without taking into account the specifics of transportation and the requirements of the compressor. This can lead to a reduction in engine life or even failure of the cooling system.
The process of preparation for operation depends on many factors: the type of refrigerant, compressor design and transportation conditions. Proper preparation It will take only a few hours, but will ensure stable operation of the equipment for decades. In this article, we will look at all the nuances that will help you avoid typical beginner mistakes.
It is important to understand that modern models, even the most reliable brands like Bosch or Liebherr, require careful handling in the first day of operation. Ignoring simple rules can void the manufacturer’s warranty, since service engineers can easily determine violation of operating conditions.
Settling time: why you can’t rush
The most critical stage is keeping the device indoors before turning it on. When transported in a horizontal position, oil from the compressor flows into the cooling system circuit. If you turn on the unit immediately, the compressor will run dry, which will lead to rapid wear or jamming.
The duration of the pause directly depends on the ambient temperature and the method of transportation. In winter, when equipment is delivered in cold weather, condensation inside the mechanisms may freeze and the oil may become too thick. A sudden start in such conditions is unacceptable.
⚠️ Attention: If the refrigerator was brought in from the cold, let it warm up to room temperature for at least 4-5 hours before any manipulations. Connecting a cold unit to the network will cause a short circuit in the wiring due to condensation.
For vertical transportation, the waiting time is minimal, but it should not be neglected. Even if the unit was standing level, vibrations could disrupt the balancing of the working fluids. Technical break allows the system to come into equilibrium.
What happens if you ignore the settling time?
If you turn on the unit immediately after horizontal transportation, the oil will enter the refrigeration chamber circuit. The compressor will try to pump incompressible liquid, which will lead to water hammer, valve breakage and expensive repairs.
Below is a table with recommended holding time depending on conditions:
| Transportation conditions | Minimum settling time | Special instructions |
|---|---|---|
| Vertical, summer | 2-3 hours | Enough to stabilize the oil |
| Vertical, winter | 4-5 hours | Need to be warmed up to room temperature |
| Horizontal, summer | 8-12 hours | The oil must completely drain into the crankcase |
| Horizontal, winter | 12-24 hours | Maximum period for evaporation of condensate |
Installation and site preparation
Before unpacking the equipment, it is necessary to prepare the site. Flat surface is a mandatory requirement for the correct operation of the No Frost system and the correct closing of the doors. A misalignment of even 2 degrees can cause the door to open by itself or, conversely, not to fit tightly.
Use a building level to check the horizontal level. Adjustment is carried out using the front support legs, which are usually unscrewed with a key or manually. The rear wheels are often just support wheels and are not adjustable.
It is important to provide the necessary clearance for ventilation. The compressor gets hot during operation and requires free air circulation. If you move the unit close to the wall, the heat exchange will be disrupted, which will lead to an increase in energy consumption.
- 📏 The minimum distance from the back wall to the wall is 5-7 cm.
- 📏 From the side walls to the furniture - at least 3 cm.
- 📏 From the top to the ceiling or cabinets - at least 10-15 cm.
- 📏 The distance from heating devices (stoves, batteries) is at least 50 cm.
Make sure that the outlet into which the device will be plugged in is grounded. The use of various extension cords and tees is not recommended, as they can cause a voltage drop or overheating of the contacts.
Primary cleaning and odor elimination
The inside of a new refrigerator often has a specific technical smell of plastic and lubricants. You cannot load food into such a unit - they can absorb foreign aromas. The first step is to carry out a thorough wash.
Remove all shelves, drawers and containers. Wash them with warm water and a mild detergent or baking soda. The use of aggressive chemicals, chlorine-containing substances or abrasive sponges is strictly prohibitedas this can damage the coating and plastic.
⚠️ Attention: Do not use hot water to wash glass shelves if they are cold. A sharp temperature change can lead to the appearance of microcracks or complete destruction of the glass.
The inner walls of the chamber are also wiped with a soft cloth soaked in a soda solution (1 tablespoon per liter of water). This will not only clean the surface, but also neutralize odors. After wet cleaning, all elements must be completely dry.
Pay special attention to the rubber seals on the doors. They need to be wiped separately, removing the factory grease that is sometimes used during assembly. Clean rubber bands will ensure a tight seal and prevent ice from freezing in the future.
First switching on and checking operation
After the unit has settled, been washed and installed in place, the moment of truth comes - the first switching on. Insert the plug into the outlet. Modern electronically controlled models may beep to indicate power is supplied.
Indicators on the display or control panel may light up. In some models Samsung or LG you need to manually activate the cooling mode if it does not turn on automatically. Leave the refrigerator to run idle (without food) for at least 2-3 hours.
During this period, the chambers are initially cooled and the temperature regime is formed. You may hear various sounds: refrigerant gurgling, relay clicking, compressor humming. These are normal operating sounds, but they should not be loud or intermittent.
Check the operation of additional functions: ice generator, freshness zone, water dispenser. Make sure that the light inside the cells comes on when the door is opened and goes off when closed. If after 3-4 hours of operation the walls inside are cold, and there is no ice on the shelves (except for the evaporator area), the equipment is in good working order.
Loading with products: rules and restrictions
When the refrigerator has reached the required temperature, you can start loading. However, this must be done gradually. If you fill the chambers with a large amount of warm products at once, the compressor will work at its limit, trying to cool the volume.
On the first day, it is not recommended to load more than 50% of the useful volume. It is better to distribute the food evenly so that cold air can circulate between them. This is especially important for systems Total No Frostwhere airflow is the main principle of operation.
- 🥩 It is better to place meat and fish on the bottom shelf or in the freshness zone.
- 🥛 Dairy products require a stable temperature, place them on the middle shelves.
- 🥬 Vegetables and fruits are stored in the lower drawers, where the humidity is higher.
- 🍺 It is most convenient to place drinks on door shelves, where the temperature is slightly higher.
Do not place hot foods inside. This will not only create an extra load on the motor, but will also increase the temperature throughout the entire volume, which can negatively affect already cooled products. Allow the food to cool to room temperature.

Typical startup errors
Even after studying the instructions, users often make mistakes that can cost expensive equipment. One of the most common is ignoring transport fasteners. In some models, the compressor or other moving parts may be secured with bolts or brackets.
If the transport locks are not removed, vibration during compressor operation will not be dampened, which will lead to excessive noise and destruction of the fasteners. Typically, such items have bright yellow or red stickers that say “Remove before use.”
Another mistake is installing the refrigerator near a heat source or in direct sunlight. The thermostat will “think” that the chamber is warm and will cause the compressor to run continuously. This will lead to overheating and increased energy consumption.
⚠️ Attention: Do not use the refrigerator for storing non-food products (chemicals, medicines without temperature control, explosives), unless this is provided for in the special instructions of the model.
It is also worth mentioning the error in choosing a place. Installation on an uneven, skewed floor means that condensation does not flow into the drainage tray, but flows out or remains inside, causing mold. Adjusting the legs is a mandatory step.
The myth of an empty refrigerator
There is an opinion that an empty refrigerator works worse. In fact, modern units maintain temperature perfectly even without load. However, a completely empty unit loses cold faster when the door is opened, since the air does not have the heat capacity of the products.
Checklist after 24 hours
A day has passed since the first start. This is the final stage of verification. You need to make sure that all systems are working properly. Check the temperature in the main chamber (should be around +4°C) and in the freezer (-18°C).
Inspect the back wall and the floor around the device. There should be no puddles or traces of water. The presence of moisture may indicate a clogged drain hole or improper installation. Also check whether the sides of the case are overheating (warm sides are the norm for heat dissipation).
If all parameters are normal, you can proceed to normal operation. Regularly monitor the cleanliness of the condenser grille at the back (dust reduces efficiency) and defrost it in time if the model does not support automatic defrosting.
Following these simple rules will allow your new assistant to serve faithfully for many years, keeping food fresh and your budget intact.
How long can you not open the refrigerator after the first switching on?
It is advisable not to open the doors during the first 2-3 hours of operation until a stable temperature is established. Frequent opening during this period causes the compressor to work longer.
Is it normal for the refrigerator to hum loudly when first started?
Yes, when first started, the compressor may work harder and noisier than usual, since it cools an empty volume. It is also possible that the refrigerant may gurgle. If the noise does not subside after a day and is accompanied by vibration, contact service.
Do you need to wash a new refrigerator with soda or just water?
Water is usually not enough to remove factory dust and odors. A solution of baking soda (1 tablespoon per liter) is the optimal safe product that disinfects and removes technical odors without harming the plastic.
Is it possible to immediately put a freezer full of food?
No, this is a mistake. A sudden heat load can “kill” the compressor. Load the freezer gradually, in small portions, giving each batch time to freeze.
