Modern household appliances require a careful approach not only during operation, but also at the stage of initial installation. Correct installation of a refrigerator with the system No Frost is the foundation of its long-lasting and quiet operation. Many owners make the mistake of believing that it is enough to simply bring the unit into the kitchen and plug it into an outlet, but ignoring technical nuances can lead to increased noise, vibration or even breakdown of the compressor.
Unlike older models with a drip system, devices with No Frost equipped powerful fans that circulate air inside the chambers. This creates specific requirements for the stability of the housing and the distance to the walls. If you want your refrigerator to serve for years without complaints, you must strictly follow the sequence of actions described in this guide.
In this article we will analyze all the stages: from choosing a location to the first start-up. We will pay special attention to alignment, since body misalignment is the main cause of noise and improper operation of the doors. We will also touch upon the topic of transportation bolts, which are often forgotten to be removed, which leads to serious damage to the unit the first time it is turned on.
Choosing the optimal location
The first thing that competent installation begins with is the choice of location. The refrigerator should not be placed close to a wall or furniture. The system No Frost implies the presence of a condenser that needs constant heat removal. If the air circulation is disrupted, the compressor will begin to wear out, trying to maintain the set temperature.
In addition, it is important to consider the direction in which the doors open. Make sure that when open, the doors do not block the passage or touch adjacent furnishings. Some models allow you to move the doors to the other side, but it is better to foresee this in advance so as not to do unnecessary work.
⚠️ Attention: It is strictly forbidden to install the refrigerator in close proximity to heating radiators, stoves or in direct sunlight. Heating the housing from the outside causes the unit to consume more electricity.
It is also worth remembering the floor covering. A heavy unit can push through soft linoleum or leave marks on the laminate. If the floor is uneven, additional adjustment of the supports will be required, which we will discuss below. Ideally, the surface should be hard and horizontal.
Preparing for installation and removing packaging
After delivering the equipment to the premises, do not rush to immediately remove the packaging materials. Allow the refrigerator to stand upright, especially if it was transported at low temperatures. The oil in the compressor needs time to drain into the crankcase and warm up to room temperature.
The unpacking process requires care. Remove the cardboard box and remove the foam inserts and tape. Pay special attention to the interior: remove all shelves, drawers and documentation. Often inside the chamber there are bags with fasteners for shelves or instructions that need to be removed before starting work.
The most important step is finding and removing the shipping bolts. They secure the compressor and prevent damage during transport. If you forget to unscrew them, the refrigerator will vibrate and rumble heavily during operation, and the compressor can quickly fail.
☑️ Check before installation
After removing the fasteners, the holes are usually closed with plastic plugs included in the kit. Save the bolts and packaging in case of re-transport or call for service. Now the unit is ready for positioning.
Technology for leveling the body
Alignment is a critical step for refrigerators with the system No Frost. An incorrect angle of inclination can result in the door not fitting tightly to the body or, conversely, opening spontaneously. In addition, the misalignment causes an uneven load on the compressor bearings.
For adjustment, front supports are used, which can be rotated manually or with a wrench. Your task is to achieve such a position that the body is strictly vertical, and the doors close on their own when opened to 45 degrees. This is ensured by a slight deflection of the body back.
| Parameter | Normal value | Permissible deviation |
|---|---|---|
| Tilt back | 1-2 degrees | up to 3 degrees |
| Gap at the wall | 5-7 cm | minimum 3 cm |
| Gap on the sides | 5 cm | minimum 2 cm |
Use a building level, applying it to the top panel and side walls. If the level shows skew, tighten the corresponding leg. Don’t be afraid to apply force, but do it smoothly so as not to strip the thread.
Why is tilting back important?
A slight tilt of the body back (when the front legs are slightly higher than the back ones) ensures that the door closes automatically under the influence of gravity. This prevents loss of cold if you forget to slam the door tightly, and reduces the load on the seal.
Organization of ventilation gaps
The efficiency of the system No Frost directly depends on heat transfer. Hot air should flow freely from the rear wall where the radiator is located. If you build a refrigerator into a niche without maintaining clearances, it will overheat.
The minimum distance to the back wall should be at least 5-7 centimeters. It is also advisable to leave space on the sides, especially if the refrigerator is located between cabinets. Some models of built-in appliances have special ventilation channels, but for free-standing models the rule of free air circulation is the same.
If you plan to install the unit in a deep niche, make sure that the height of the space allows air to rise up and escape. Sometimes it is necessary to make additional holes in the furniture to allow air flow to pass through.
⚠️ Attention: Covering the ventilation holes with decorative panels or moving them tightly against the wall will increase the temperature of the condenser. This may trigger a safety shutdown or shorten the life of the compressor.
First turn on and check operation
After the refrigerator is installed and leveled, you can move on to the electrics. Connect the device only to a separate grounded outlet. The use of extension cords or tees is not recommended, as the starting currents of the compressor can be high.
When turning on for the first time, do not load products immediately. Let the unit run idle for at least 2-3 hours until it reaches operating temperature. At this time, listen to the sounds of operation: you should hear a steady hum of the compressor and periodic turning on of the fans.
Check the operation of the system No Frost. Some time after startup, cold air should begin to circulate inside the chambers. Make sure that there is no ice crust forming on the walls of the freezer compartment and that there are no puddles in the refrigerator compartment.
Common mistakes during self-installation
Even careful study of the instructions does not always save you from mistakes. Often, users forget to remove the shipping wedges from the inner boxes or do not check the seal for leaks after installation. Another common problem is ignoring instructions on minimum distances.
Another mistake is installation on a soft or fleecy surface without a protective backing. Carpet pile clogs the ventilation holes at the bottom (if there are any) and interferes with normal heat transfer. In addition, the pile can wrap around rotating parts if access to them is open.
- 🔌 Ignoring grounding: Connecting to a socket without a grounding contact can lead to an electric shock when touching the case.
- 📏 Lack level: installation "by eye" leads to skewed doors and difficulties with closing them.
- 🔩 Forgotten bolts: operation of the compressor with a fixed suspension causes severe vibration and noise.
If you notice that the refrigerator makes strange sounds (gurgling, clicking) in the first hours of operation, do not panic. The refrigerant begins to circulate through the system, and such sounds may be normal. However, a metallic clang or hum requires contacting a specialist.
What to do if the refrigerator does not start after installation?
First of all, check for voltage in the outlet. Make sure that the temperature regulator is not in the "0" or "Off" position. If the equipment has just been brought in from the cold, the protection against temperature changes may have worked - let it stand turned off for several hours.
Is it possible to place the refrigerator on the balcony?
Most manufacturers do not recommend operation at temperatures below +10°C or above +32°C. On an unheated balcony in winter, the oil in the compressor will thicken, and in summer overheating is possible. This may lead to damage that is not covered by the warranty.
Do you need to wash the refrigerator before first use?
Yes, absolutely. Wipe the inner chambers with warm water and a mild detergent to remove factory dust and plastic odors. After this, wipe all surfaces dry with a clean cloth.
Why do the side walls of the refrigerator get hot?
In modern models, the condenser is often built into the side walls. Their heating to 40-50 degrees in the first hours of operation or during active freezing is a normal process of heat removal.
How often do you need to defrost No Frost?
The system No Frost does not require regular defrosting to remove ice, since moisture is removed automatically. However, once every year or two it is recommended to carry out preventive defrosting and washing for hygiene and cleaning of drainage channels.
