Purchasing new household appliances is always a joyful event, which, however, requires a competent approach to the first use. If you have become the owner of a modern unit from Hisense, you need to know how to properly perform its initial startup in order to avoid breakdowns and guarantee a long service life of the compressor. Many users make the mistake of turning on the device immediately after unpacking, which can lead to serious consequences for the refrigerant and oil in the system.
In this article we will analyze in detail the entire process: from unpacking to setting the optimal temperature in the chambers. You will learn why vertical position plays a key role during transportation, how long you need to wait before plugging it into the network, and what indicators indicate normal operation of the device. Proper preparation is the key to stable cold in your home.
You should not ignore the manufacturer’s recommendations specified in the technical data sheet, as they are designed taking into account the characteristics of specific models. Hisense. We have structured the information so that you can quickly find the answer to any question related to the initial activation of your new refrigerator, be it a single-chamber model or a large Side-by-Side.
Preparing the site and unpacking the equipment
The first step before you think about turning it on is the correct installation of the equipment. Hisense refrigerator requires flat and stable surface, away from direct sunlight and heating devices. The distance to the walls should be at least 10 cm to ensure normal air circulation around the condenser, which is critical for effective heat removal.
The unpacking process must be careful. Remove all shipping tapes, foam blocks, and protective film. Pay special attention to the interior: remove all tape securing shelves and drawers, and also check if there are any additional accessories inside the package, such as egg trays or instructions.
⚠️ Attention: Do not use sharp objects (knives, scissors) to remove the protective film from the case, as there is a high risk of damaging the paintwork or the outer wall of the chamber.
After removing the packaging, it is necessary to thoroughly sanitize the internal chambers. Even a new device may have a residual smell of plastic or factory grease. Wipe all surfaces with a soft cloth soaked in a weak soda solution or a special refrigerator cleaner.
Dwell time: why you can’t turn it on right away
The most important nuance, which is often forgotten, is the standstill time. If the refrigerator Hisense was transported in a horizontal position or was strongly tilted, compressor oil could leak into the refrigerant circuit. An instant start in this state will lead to water hammer and failure of the compressor.
Experts recommend maintaining the following time intervals before connecting to the power grid for the first time:
- 🕒 If the equipment was transported strictly vertically, 2-4 hours are enough to stabilize the temperature and pressure.
- 🕒 When transported in an inclined state (more than 40 degrees), at least 8-12 hours are required.
- 🕒 If the refrigerator was lying horizontally, the minimum standing time is 24 hours.
Ignoring this rule is the most common reason for calls to service centers in the first month of operation. The oil must completely drain back into the compressor crankcase, and the refrigerant must take its place in the system. Patience in this case, this is an investment in the durability of the device.
What will happen if you turn it on ahead of time?
If you start the compressor while the oil is in evaporator tubes, it can clog the capillary system. This will lead to the fact that the refrigerator will stop freezing, and the compressor will work with overload, which is fraught with its combustion. Repair in this case will be difficult and expensive.
First connection to the electrical network
After the required standstill time has passed, you can begin connecting. Make sure that the outlet you plan to plug into is grounded and meets the power requirements (usually standard 220-240V household outlets). It is not recommended to use extension cords or tees, as this may cause poor contact and heating of the wires. Hisense, is grounded and meets power requirements (usually standard household sockets for 220-240V). It is not recommended to use extension cords or tees, as this may cause poor contact and heating of the wires.
Insert the plug into the outlet. In modern electronically controlled models, the display will light up, and in mechanical models, you may hear a quiet click of the thermostat or just feel a slight vibration of the case after a few minutes. It is important to check the tightness of the plug to the socket - it should not dangle.
| Control type | Power indicator | User actions |
|---|---|---|
| Mechanical | No sound, operation compressor | Turn the thermostat knob |
| Electronic | Lighting display, sound signal | Press the activation button (if any) |
| Smart / Wi-Fi | Blinking network indicator | Follow the instructions for connecting the application |
Pay attention to the behavior of the compressor in the first minutes. It may not start immediately, but after 5-10 minutes. This is normal operation of the protective relay, which prevents frequent starts. If after 15-20 minutes the unit does not make any sounds or vibrate, check the presence of voltage in the network.
Setting the temperature mode
Immediately after turning on, the refrigerator begins to gain temperature. During this period, you should not load it with foods, especially warm ones. Let the equipment run idle for 2-3 hours to stabilize the climate inside the chambers. For models with a system No Frost this time can be increased to 4-5 hours.
The setting is carried out depending on the type of control:
- ❄️ Mechanical: turn the dial inside the camera to a value from 2 to 3 (middle position). Do not immediately set it to maximum, this will create an extra load.
- ❄️ Electronic: use the panel on the door. The recommended temperature for the refrigerator compartment is +4°C, for the freezer compartment - -18°C.
⚠️ Attention: During the hot season or when fully loaded with food, the temperature inside the chambers may increase. In such cases, a temporary increase in the cooling mode is allowed, but after stabilization, return the settings to standard values.
If your model Hisense is equipped with a zoom freshness or zero chamber, make sure that the dampers are open and the air is circulating correctly. Some models require manual activation of these functions through the menu.
Checking operation and initial diagnostics
During the first day of operation, it is important to periodically check the operation of the unit. Listen to the sounds made by the compressor: they should be smooth, without knocking, grinding or loud humming. Periodic quiet gurgling or hissing is allowed - this is the refrigerant moving through the system pipes No Frost.
Check the tightness of the doors. The seal should touch the body tightly around the entire perimeter. A simple test: press a piece of paper between the door and the frame and try to pull it out. If the paper is pulled out with force along its entire length, the seal is in order.
Pay attention to the heating of the side walls. In modern refrigerators, the condenser is often built into the side panels, so they can heat up to 40-50 degrees. This normal operating processand not a sign of a malfunction.
☑️ Diagnostics on the first day
Typical errors at first start
Even carefully reading the instructions does not always guarantee the absence of errors. Users are often in a hurry and make mistakes that can shorten the life of the equipment. One of the most common is installing the refrigerator close to the wall or in a niche without gaps for ventilation.
Another common mistake is ignoring the tilt level. The refrigerator Hisense must stand strictly horizontally or with a slight tilt back so that the door closes itself under the influence of gravity. If the door opens on its own or does not reach the end with a slight push, it is necessary to adjust the legs.
⚠️ Attention: Never wash the refrigerator with hot water or aggressive chemicals immediately after purchase. A sharp temperature change can deform the plastic elements of the inner chamber.
Loading a large amount of warm products in the first hours of operation is also considered a mistake. This forces the compressor to work at the limit of its capabilities, which is extremely undesirable at the time of initial grinding in of parts.
Frequently asked questions (FAQ)
How long does the Hisense refrigerator take to reach temperature for the first time?
Usually, it takes 2 to 4 hours of idle operation to achieve the specified parameters. Complete stabilization of the temperature in all points of the chambers can take up to 24 hours, especially in large-volume models.
Is it normal for the refrigerator to make noise when first turned on?
Yes, in the first hours of operation the sounds may be more noticeable due to the circulation of the refrigerant and the operation of the No Frost system fans. However, loud knocking or vibration of the case is not normal and requires checking the installation level.
Does the seal need to be lubricated before first use?
This is not urgently necessary, since new seals have already been treated. However, wiping with silicone grease or glycerin will extend the life of the rubber and improve the tightness of the seal.
Is it possible to immediately set the refrigerator to maximum cold?
It is strictly not recommended. A sharp start at maximum speed creates a peak load on the compressor. Start with average values and increase power only if necessary.
