Starting a new one or something that has not been used for a long time cooler with cooling function requires compliance with a certain algorithm of actions, which is often ignored by users. Simply connecting to the electrical network without prior preparation can lead to incorrect operation of the compressor or water circulation system. Unlike a conventional electric kettle, it uses a refrigerant that requires time to stabilize after transportation.
In this guide, we will analyze all the stages of activating the device, starting from unpacking and ending with setting the temperature conditions. You will learn why it is important to wait a pause before turning on and how to check the tightness of the system before adding liquid. Following these simple rules will extend the life of the equipment.
Initial preparation and installation of the device
The first step is correct installation device in the selected place. The cooler should be placed on a flat, stable surface away from direct sunlight and heat sources such as radiators or ovens. The distance to the walls should be at least 10-15 centimeters to ensure normal ventilation of the condenser.
After installation, all transport elements must be removed. Pay special attention to the back panel, where it is often secured compressor. If the device was transported in a horizontal position, it should absolutely not be turned on immediately.
⚠️ Attention: If the cooler was lying during transportation, oil from the compressor could flow into the cooling circuit. It is necessary to allow the device to stand in a vertical position for at least 4-6 hours (preferably a day) before connecting to the network for the first time.
Check the integrity of the case and the absence of visible damage to the tubes or wires. Make sure the outlet is grounded and meets the power requirements specified in technical data sheet. Unstable voltage can damage the control electronics.
Preparing the water supply system
Before wondering how to turn on a cooler with a refrigerator, you need to properly prepare the water circuit. Using low-quality water will lead to rapid scale formation on the heating elements and clogged filters. It is recommended to use bottled water or water that has undergone deep purification by reverse osmosis.
The filling process depends on the type of loading: bottle or flow-through. For bottle models, remove the protective film from the neck of the bottle and quickly turn it over, placing it on the receiving socket. It is important not to spill water on the electrical contacts in the bottle niche.
- 🧼 Thoroughly rinse the internal tanks if the device is new by running a drain cycle without heating.
- 💧 Make sure that there are no air pockets in the system by opening the cold water tap until a steady stream appears.
- 🔒 Check the reliability of the fixation bottle or connecting a flow filter.
If using a system with pump, make sure that it is immersed in water and connected to the power connector inside the niche. The lack of water in the pump when turned on can lead to its burnout.
First connection to the electrical network
After the device has settled and filled with water, you can proceed to the electrical connection. Insert the plug into the outlet. The indicator on the front or rear panel should light up indicating that power is supplied. At this stage, it is too early to open the taps for drinking.
Many modern models are equipped with a dry-running protection system. This means that heating element is not activated until the sensors confirm the presence of a sufficient volume of liquid. The heating indicator may flash or not light up until the internal tank is completely filled.
Sequence of actions for the first start:1. Connect to the network.
2. Wait until the power indicator lights up.
3. Open the cold water tap for 10-15 seconds (bleeding the system).
4. Close the tap and check for leaks.
Some models require manual activation of the cooling and heating modes if they do not turn on automatically. Switches on the back wall or touch panels on the front are designed for this.
Setting temperature modes
Temperature control is a key stage of setup. Depending on the model, adjustment can be carried out by mechanical screws inside the case or electronically through the control panel. Thermostat responsible for maintaining the specified parameters.
For mechanical models, you will need to remove the front or side panel (after disconnecting the device from the network!). Inside you will find two controls, usually labeled "Heat" and "Cool". Rotating the screw clockwise usually increases the temperature, counterclockwise decreases it.
| Parameter | Optimal value | Adjustment range | Note |
|---|---|---|---|
| Cooling | 5-10 °C | 4-15 °C | Depends on ambient temperature |
| Heating | 85-95 °C | 80-98 °C | For brewing tea |
| Child lock | Activated | On/Off | Blocks the hot water tap |
Electronic models, such as Vatten or HotFrost with a digital display, allow you to set the temperature with an accuracy of a degree. Use the "+" and "-" buttons on the control panel to set the desired values. Do not forget to confirm your choice if the model requires saving the settings.
Why does the cooler take a long time to gain temperature?
The first cooling or heating cycle always takes longer (up to 2-3 hours), since the system must cool or heat the entire volume of water in the internal tank. The process will go faster in subsequent times.
Indication and status signals
Understanding the light indication signals will help you quickly diagnose the condition of the device. Each color and blinking mode LEDs carries certain information about the operation of the systems.
Usually the green indicator is constantly on during normal operation. Red color can indicate heating process or, in flashing mode, an error. If you see a flashing red light, check the presence of water in the bottle and the position of the taps.
- 🟢 Green is on - standby mode or ready to work.
- 🔴 Red is on - the water heating process is in progress.
- 🔵 Blue is on - cooling mode is active (compressor works).
- 🟠 Orange flashing - sensor malfunction or lack of water.
It is important to monitor the behavior of the compressor. It should turn on periodically, maintain the temperature, and turn off. Continuous operation without shutting off may indicate a refrigerant leak or a malfunction of the thermostat.
⚠️ Attention: If the indicators behave erratically or flash all at the same time, this may indicate a failure in the electronic control module. In this case, try completely disconnecting the device for 10-15 minutes to reboot the system.
Typical startup problems and their solutions
Even if you follow all the instructions, nuances may arise. Often users are faced with a situation where the cooler turns on, but the water does not cool. This may be due to the fact that the room is too hot, and compressor power there is not enough heat to quickly dissipate, or the device is installed close to the wall.
Another common problem is the lack of hot water when the indicator is on. In 90% of cases this is airing of the system. It is necessary to open the hot water tap and keep it open until there is a smooth stream without “spitting” of air. After this, close the tap and wait for reheating.
If you hear loud noise or knocking during operation, check the stability of the installation. The cooler must stand strictly horizontally. Also, the source of noise can be vibration tubes touching the case - they can be carefully moved away by hand (only after disconnecting from the network!).

Operation rules and safety
For durability water cooler it is important to follow operating conditions. It is not recommended to leave the device plugged in if you are leaving for a long time (more than 3-4 days). This will save electricity and the resource of heating elements.
Regularly, approximately every six months, it is necessary to disinfect the internal tanks. Even if bottled water is used, biofilms can form in the tank over time. Use special tablets or citric acid solution, following the instructions for the disinfector.
⚠️ Attention: Never turn on the heating mode if the water level in the system is below the minimum mark. This will lead to instant burnout of the heating element. Modern models have protection, but it's not worth the risk.
Keeping the area around the bottle receptacle clean is also critically important. Moisture trapped there may cause a short circuit. Wipe this area with a dry cloth every time you replace the bottle.
What to do if the cooler does not turn on after installation?
First of all, check for voltage in socket. Next, make sure the power switch on the rear panel (if equipped) is set to the "I" or "On" position. If the device is a bottle-type device, check whether the protective seal has been removed from the neck and whether the bottle is seated tightly - some models have a mechanical valve that prevents you from turning on the power without the container installed.
Is it possible to turn on the cooler without a bottle of water?
For a short time - yes, to check the electronics. However, turning on heating or cooling modes without water is strictly prohibited. This will lead to failure of the heating element and the compressor, since heat is removed precisely through water.
Why does the cooler hum after switching on?
Humming is the normal sound of the compressor. However, the sound should be smooth and quiet. If the humming noise is accompanied by chassis vibration, check the leveling feet. If the sound is similar to gurgling, this is the refrigerant circulating, which is also the norm for a working system.
How long does it take for the water to cool in a new cooler?
Primary cooling of the full volume of the tank (usually 1-2 liters) takes from 1.5 to 3 hours depending on the room temperature and the power of the model. After this, the compressor will turn on periodically to maintain the temperature.
