Replacement refrigeration equipment is not just rearranging furniture, but a technically complex process that requires compliance with safety rules and technological breaks. Many owners make the mistake of starting operation immediately after plugging the plug into the outlet, which can lead to compressor failure and loss of warranty. The correct sequence of actions when dismantling the old unit and installing a new one guarantees a long service life of the equipment.
The replacement process includes several critical stages: from preparing the opening to the final adjustment temperature conditions. Ignoring the nuances of transportation or incorrect alignment of the housing often causes increased noise and vibration. In this article, we will look in detail at how to avoid typical installation mistakes.
Preparation for replacement and dismantling of old equipment
The first step is to completely empty the freezer of food. If the old unit is still functioning, it is recommended to defrost it a day before the planned work. This will avoid water leakage when moving and will facilitate the process of cleaning the internal surfaces. refrigerator compartment and a freezer for food. If the old unit is still functioning, it is recommended to defrost it a day before the planned work. This will avoid water leakage when moving and will make cleaning the internal surfaces easier.
Next, you need to disconnect the device from the power supply. Pull the plug out of the socket carefully, without pulling the wire, so as not to damage power cable. For models connected to the water supply (system No Frost with an ice maker), you need to turn off the water supply valve and disconnect the flexible connection, first placing a container to drain the remaining liquid.
⚠️ Attention: Before you begin to pull out a heavy unit, make sure that the path is clear. Sudden jerks can damage the flooring or cause a back injury.
Be careful when rolling out an old refrigerator. If the appliances are built-in, you will need to dismantle the front panels and unscrew the fasteners securing the body in the niche of the kitchen unit. For free-standing models, it is enough to free up the space around.
Choosing a location and preparing a niche for installation
New equipment may have different dimensions from its predecessor. Before installation, carefully measure the height, width and depth of the niche. It is important to leave ventilation gapswhich are necessary to remove heat from the condenser and prevent overheating of the motor.
The floor at the installation site must be flat and durable. If the flooring is soft (linoleum, cork), it is recommended to place a hard plate of plywood or plastic under the supports to prevent pressing and ensure stability. Check the proximity electrical outlet —it is not advisable to use an extension cord for the refrigerator.
Clean the space from dust and construction debris. If you are replacing a refrigerator as part of a kitchen renovation, make sure all finishing work (painting, tiling) is completely finished and dry. The humidity in the room should not exceed standard values.
Transporting and unpacking a new refrigerator
When transporting a new unit to the installation site, strictly follow the rule: vertical position or tilt no more than 40 degrees. Shipping or moving "lying down" can cause oil to flow from the compressor into the refrigerant circuit, which is critical to the operation of the system.
Remove all packaging: cardboard, foam pads and tape. Pay special attention to the shipping bolts if they are located on the rear wall (more common in combination models or when additional fasteners are present). Save the packaging materials in case you need to transport it again.
Visually inspect the case for dents and chips. Check the integrity of door handles and seals. It is better to detect any defects before installation, before the deadline for filing a claim with the store has expired.
⚠️ Attention: If the refrigerator was transported horizontally, before turning it on, it must stand in a vertical position for at least 4-8 hours (or better yet, a day) to allow the oil to drain into the compressor.
Installation and alignment of the housing
Install the refrigerator in the prepared place. Now you need to perform the exact alignment. Use the adjustable support feet by rotating them clockwise or counterclockwise. The body should stand stable, not wobbling when pressed lightly.
An important nuance: the doors must close independently under the influence of gravity. To do this, the back of the refrigerator should be raised slightly higher than the front (about 1-2 cm). This is achieved by twisting the front legs. Check the operation of the mechanism door closerif it is provided by the model.
☑️ Checking the installation
After alignment, check the gaps between the walls of the refrigerator and the furniture again. The minimum distance at the back and sides is usually 5-7 cm, at the top - at least 10 cm. Violation of these standards leads to an increase in energy consumption.
Comparison of characteristics: Old vs New model
When equipment is replaced, operating requirements often change. Below is a table that helps you understand the difference in approaches to servicing old and modern models.
| Parameter | Old models (before 2010) | Modern models |
|---|---|---|
| Defrost type | Manual (requires defrosting) | Automatic (No Frost) |
| Refrigerant | Freon R12, R134a | Freon R600a (isobutane) |
| Noise level | High (42-45 dB) | Low (34-38 dB) |
| Energy consumption class | A, B, C | A+, A++, A+++ |
Modern refrigerants, such as R600a, are more environmentally friendly, but require better installation and soldering of pipes during repairs. Also, new models are often equipped with inverter compressors, which are quieter and more economical, but are sensitive to power surges.
Why are modern refrigerators quieter?
Modern models use inverter compressors that do not turn off completely, but smoothly regulate the power, avoiding sudden starts that create the main noise.
First switching on and checking operation
After the refrigerator has stood for the required time, you can start the first start. Make sure that the power indicator on the control panel B lights up. During the first minutes of operation, the sound of refrigerant gurgling can be heard - this is normal process gas circulation through the system.
Do not load the products immediately. data-i="119">inside the chambers. Only after achieving stable cold can you put food in. temperature inside the cameras. Only after achieving stable cold can food be stored.
Check the operation of additional functions: ice generator, water dispenser (if equipped), freshness zone. Make sure that the doors fit tightly around the entire perimeter and the magnetic seal has no gaps.
Common mistakes when replacing it yourself
One of the most common mistakes is ignoring the instructions for transportationtrying to quickly start the refrigerator after tilting it more than. at 40 degrees without settling often ends with hydraulic shock in the compressor.
Another mistake is installation close to the wall. Many users forget that the rear grille must “breathe”. The lack of clearance leads to the fact that the refrigerator works non-stop, trying to reduce the temperature, which reduces the life of the engine.
⚠️ Attention: Never use aggressive chemicals or abrasive sponges to clean the internal chambers immediately after installation - this can damage the antibacterial coating of the plastic.
Connecting to the network through cheap ones is also considered an error. extensions or tees. The refrigerator is a powerful consumer, and poor contact at the connection point can cause heating and melting of the wires.
What to do if the refrigerator is humming after installation?
Check whether the refrigerator pipes are touching the wall or furniture. Often vibration is transmitted to structures, creating resonance. Move the unit 1-2 cm.
How long should the refrigerator stand after delivery?
If the refrigerator was transported vertically, 2-3 hours is enough. If there was horizontal transportation or a strong tilt, you must wait from 4 to 24 hours (the exact time is indicated in the passport of the specific model) before connecting to the network.
Is it possible to place the refrigerator on a heated floor?
Yes, it is possible, but with restrictions. The surface temperature should not exceed 27-28°C. Excessive heating from below impairs the efficiency of the compressor and increases energy consumption.
Do you need to wash a new refrigerator before use?
Absolutely. There may be a technical plastic smell inside. Wipe the chambers with a soft cloth soaked in a weak solution of soda or vinegar, and leave the doors open for several hours to ventilate.
Why does the refrigerator not cool immediately after turning on?
Modern models with refrigerant R600a and large volumes of chambers may take up to 12 hours to enter operating mode upon first boot. If there is no cold after a day, contact the service.
