Moving to a new apartment or the need to deliver large household appliances from the store often puts the owner in a dilemma: to transport a bulky unit strictly vertically or risk putting it on its side. The dimensions of modern models and low ceilings in freight elevators dictate their conditions, forcing one to seek compromises with the manufacturer’s instructions. The issue of the safety of such transportation is of concern to everyone who does not want to lose the warranty or face costly repairs to the compressor immediately after installation.
Theoretically, any deviation from the vertical position creates risks for the internal systems of the refrigerator, however, practice shows that if certain rules are followed, horizontal transportation is permissible. Key factor here it is not so much the fact of tilting itself, but the correct preparation of the equipment and the subsequent period of rest before the first turning on. Ignoring these nuances can lead to mixing of coolant with oil, which is critical for engine operation.
In this article we will analyze the physical processes occurring inside the system when tilted, determine which side is safer to place a particular model on, and draw up a clear algorithm of actions. You will learn why the settling time directly depends on the duration and position of equipment on the way, and how to minimize the risks of damage to pipelines compressor and pipelines.
Risks of horizontal transportation for a compressor
The main reason for bans on horizontal transportation lies in the design motor-compressor. Inside the sealed casing there is oil, which in working condition circulates through the system, lubricating the rubbing parts. With a strong tilt or lying position, the liquid under the influence of gravity flows into the system circuit intended for gaseous refrigerant.
If you turn on the unit immediately after delivery, the compressor will begin to pump oil rather than gas. Since the fluid is incompressible, this results in water hammer, which can instantly damage the valves or piston group. In addition, oil leaked from the crankcase will not be able to return, which will lead to the engine running “dry” and rapid overheating.
⚠️ Attention: Manufacturers often indicate in passports that transportation on its side is prohibited. This was done to minimize warranty cases, since it is almost impossible to prove that the equipment was delivered in violation of the rules at the first start.
However, if you still decide to take a risk, it is important to understand: oil does not flow out of the compressor instantly. You have a window of time until the viscous liquid fills the evaporator or condenser. That is why the speed of loading work and the subsequent rest time play a decisive role in maintaining the performance of the unit.
Which side to put it on: choosing the right side
Determining the side on which it is permissible to place the refrigerator depends on the model and location of the compressor tubes. In most cases, manufacturers recommend placing the equipment on the side opposite the tubes exiting the engine. If you place the unit on the side where the tubes come out, they may become deformed under the weight of the case, which will lead to depressurization of the system.
To determine the correct side, inspect the back wall of the refrigerator. Find the compressor (the black “barrel” at the bottom) and the copper pipes coming from it. It is usually safer to place the equipment on its side, where there are fewer tubes or they are located higher relative to the ground when laying. In some models, for example Liebherr or Atlantthe sides may be equal, but it is better to be on the safe side.
There is a rule of thumb: if you cannot accurately determine the side of the tube exit, place the refrigerator on its left side (looking at the door from the front). This is due to the fact that in many models the compressor is shifted to the right, and when laid on the left side, the tubes are on top, which reduces the risk of them being bent and squeezing out oil.
It is also important to consider the location of the handles and decorative elements. Even if it is technically safe to place the equipment on any side, the protruding parts can break under the pressure of the weight of the entire body. Surface protection and protruding elements are a secondary, but important task when planning installation.
Preparation of equipment for moving
Successful transportation begins long before loading into the back of a truck. The first step should be to completely defrost the refrigerator compartment. Even a small amount of ice inside can shift the center of gravity or, melting along the way, cause a short circuit in the wiring. After defrosting, all surfaces must be wiped dry.
The next step is fixing the internal components. Refrigerator doors must be tightly closed and secured. Masking tape, which leaves no traces of glue, or special shipping tape are ideal for this. It is better to remove the shelves and drawers and transport them separately, wrapped in soft cloth or bubble wrap so that they do not hit the walls of the chamber when shaking.
☑️ Checklist for preparation for transportation
The outer part of the case should also be protected. Use the original packaging if it is available, or wrap the refrigerator in several layers of stretch film and cardboard. This will protect the enamel from scratches and chips that may occur upon contact with fastening belts or the sides of the machine. Packaging takes on the main mechanical load.
The process of loading and fixing in transport
Loading is the most a traumatic stage for equipment. Under no circumstances should the refrigerator be dragged along the floor, even if it has plastic legs. This may damage the supports or scratch the floor covering. Use a dolly or two or three people to carry it.
When placing in a vehicle, make sure the surface is level and clean. Place thick cardboard, a blanket or foam under the refrigerator to soften road vibrations. If you are transporting equipment on its side, it should lie strictly on the selected side, without distortions or resting on tubes or handles.
| Parameter | Vertical transportation | Horizontal transportation |
|---|---|---|
| Risk for compressor | Minimum | High (without settling) |
| Required transport | High van/Gazelle | Passenger car (seats folded) |
| Time before switching on | 2-4 hours | From 8 to 24 hours |
| Probability of damage to the case | Average | Low (if correct packaging) |
Fixation in the body is required. Use straps to hold the refrigerator against the sides, but do not over-tighten them to avoid deforming the cabinet. If there are other things in the back, make sure that they cannot move and hit the equipment. Stability The cargo is the key to its integrity.
How long should a refrigerator wait after transportation
The most critical point is the rest time after delivery. This is the period required for the oil that has entered the circuit to flow back into the compressor crankcase under the influence of gravity. If you hurry and turn on the unit ahead of time, the risk of breakdown increases many times over.
Settling time depends on several factors: ambient temperature, duration of transportation and position of the equipment. If the refrigerator was transported vertically and not for long, 2-3 hours is enough. If he lay on his side for several hours, the time increases. In winter, the oil becomes more viscous, and the process of its drainage slows down.
⚠️ Attention: In winter, if the refrigerator freezes during transportation, do not turn it on immediately after bringing it into a warm room. A sudden change in temperature will cause condensation on the electronic boards, resulting in a short circuit. Allow the equipment to warm up to room temperature for at least 4-5 hours.
Optimal time intervals for various situations:
- 🕒 Less than 15 minutes in a horizontal position: 1-2 hours of rest is enough.
- 🕒 From 30 minutes to 1 hour on the side: 4-6 hours of settling are required.
- 🕒 More than 2 hours while lying down: you need to wait at least 12, and preferably 24 hours.
What happens if you turn on the refrigerator ahead of time?
Compressor It will start, but due to lack of lubrication it will start to get very hot and buzz. After some time, the thermal protection relay will operate and it will turn off. Repeated starts can lead to jamming of the piston group or burnout of the motor winding. Repair in this case is often not economically feasible.
You should not rely on “maybe”. It’s better to lose a day of time waiting for it to start than to buy a new refrigerator. Patience in this case, the cheapest insurance for your equipment.
Common mistakes when transporting yourself
One of the common mistakes is ignoring the instructions for a specific models. Some modern refrigerators with inverter compressors or other shock absorption systems may have unique requirements. For example, models LG with a linear compress may be more sensitive to shocks when laid horizontally.
Another mistake is the use of too narrow or soft fasteners. Belts cutting into the body can leave dents that disrupt the geometry of the doors or damage the thermal insulation layer. In addition, they often forget to fix the internal shelves, and they break on glass or plastic the first time the car is turned.
It is also dangerous to transport the refrigerator along with other heavy objects without a reliable partition. A moving book box or piece of furniture can penetrate the back wall, damaging the capacitor. Always leave free space around the equipment or use soft buffers.
Remember that even with ideal transportation, the warranty may be lost if the service center finds traces of improper transportation. Therefore, if possible, it is better to use the services of professional movers who are responsible for the safety of the cargo.
Is it possible to transport a refrigerator at temperatures below -5°C?
It is highly not recommended. The oil in the compressor thickens, rubber seals lose elasticity and may crack. If transportation cannot be avoided, after bringing it into the room, allow the refrigerator to warm up for at least 6-8 hours before turning it on, so that all materials return to normal temperature and properties.
What should you do if the refrigerator makes a lot of noise after turning it on?
If the noise appeared immediately after the first start after transportation, the oil may not have fully returned to the crankcase, or a water hammer has occurred. Turn off the unit, unplug it and leave it for another 6-10 hours. If the noise (hum, knocking) persists after restarting, diagnostics by a technician is necessary.
Is it necessary to remove the doors during transportation?
It is not necessary to remove the doors if you have secured them securely with tape. However, if the doorway is very narrow, removing the doors may make it easier to move through and reduce the risk of damaging the hinges or doors on the jambs. In modern models, the doors are often non-removable without a special tool, so it’s enough to simply seal them.
