Modern water cooling systems, such as Vatten, are often equipped with a built-in refrigeration module to supply not just purified, but also pleasantly cool liquid. However, after receiving and installing new equipment, many users are faced with an incomprehensible situation: water flows, but does not cool. This happens because refrigerator compressor does not start automatically immediately after being plugged into the network.
For the system to operate correctly, a number of preparatory steps are required, which are often overlooked when briefly studying the instructions. Incorrect starting can lead to false errors or even damage to the compressor if there is still air in the circulation system or the refrigerant pressure has not equalized. In this material, we will analyze in detail the algorithm of actions necessary to safely and effectively activate the cooling mode.
First of all, it is worth noting that the design of coolers Vatten assumes the presence of a separate control loop, which is activated only after an initial check of all security systems. The owner must ensure that the water bottle is installed correctly and that the device itself is on a level surface. Only after this can you proceed to manipulating the switches and buttons on the control panel.
Initial check before turning on the power
The first step will be a thorough visual inspection of the device. Make sure the cooler is placed on a stable base away from direct sunlight and heat sources. The distance to the wall should be at least 10 centimeters to ensure normal air circulation around capacitor. If the device has just been delivered from a cold room, it must be allowed to stand at room temperature for 3-4 hours.
Check the integrity of the power cord and make sure that the outlet to which you plan to connect the device is working and grounded. The use of extension cords or tees of poor quality can lead to a voltage drop, which is critical for startup compressor. Also inspect the connection points of the bottle: there should be no leaks or signs of a loose fit of the neck to the water inlet.
- 🔌 Make sure there is grounding in the outlet for the safety of the electronics.
- ❄️ Allow the device to acclimatize if it was on frost.
- 💧 Check the water level in the receiving chamber before starting the pump.
- 🌬️ Ensure free access of air to the back wall of the device.
Dry heating or operating the compressor without a coolant (water) will damage the equipment in a matter of minutes. Therefore, first make sure that the system is full, and only then apply power.
⚠️ Attention: It is strictly forbidden to turn on the cooling mode if the cooler was transported lying down or was strongly tilted. Oil from the compressor could get into the refrigerant circuit, and starting will immediately lead to water hammer and breakdown of the unit.
The algorithm for turning on the cooling mode
The process of activating the refrigeration function on coolers Vatten is standardized, but has its own nuances depending on the control panel model. On most devices, the cooling mode switch (often indicated by a blue color or a snowflake) is located on the back or top panel. Move the toggle switch to position ON or I.
After turning the switch, do not wait for the instantaneous appearance of cold water. Refrigerant it takes time to start circulating and cool the first volume of liquid in the storage tank. This process usually takes from 1.5 to 2 hours. At this time, the compressor can operate cyclically: turn on for a few minutes, then pause.
☑️ Checklist for starting cooling
If your model has a digital display, it can display the current temperature of the water in the tank. In the first minutes of operation, the readings may not change, which is normal. Temperature sensors have a certain inertia, and the electronics need time to calibrate the readings.
Listen to the operation of the device. In normal mode, you should hear a quiet hum from the compressor and occasional clicks from the thermostat. If there is a loud knocking sound, hissing or vibration of the cabinet increases, immediately unplug the device. This may indicate a malfunction of the compressor mounting or problems with the electrical part.
Setting temperature modes
Many modern models Vatten allow you to adjust the degree of water cooling. This is done either by a mechanical screw on the thermostat (located inside the housing) or through an electronic menu. For mechanical adjustment, you will need to remove the top cover and find a round regulator with graduation.
Turning the screw clockwise usually increases the temperature (makes the water warmer), and counterclockwise - lowers it. Be careful: do not set the lowest possible temperature right away. This will force compressor to work without interruption, which will lead to freezing of the tank and increased energy consumption.
| Parameter | Recommended value | Acceptable range | Impact on the system |
|---|---|---|---|
| Cold water temperature | 8-10 °C | 5-15 °C | Optimal for drinking |
| Hot water temperature | 90-95 °C | 85-98 °C | Depends on scale |
| Cycle time cooling | 15-20 min | 10-30 min | Normal mode |
| Consumption (cooling) | 80-100 W | 70-120 W | In operating mode |
Electronic settings are carried out through the panel on the front. By pressing a combination of buttons (often holding the "Cold" button for 3-5 seconds), you can enter the menu and select the desired temperature. The exact combinations are always indicated in the passport of a specific model Vatten.
What to do if the water does not cool to the set temperature?
If you set it to 5 degrees and the water is warmer, check if the cooler is located next to the battery or in the sun. It is also possible that the thermostat requires calibration or there is little freon in the system.
Indication and signals of system operation
Understanding the indicator lights helps to quickly diagnose the condition of the device. On the cooler control panel Vatten there are usually lights indicating the heating and cooling mode. A green or blue indicator that is constantly on means that the cooling mode is active and the system is operating normally.
If the indicator starts flashing, this is a signal that it has entered standby mode or that the set temperature has been reached. The compressor is resting at this moment. However, if flashing occurs in a certain rhythm along with a sound signal, refer to the instructions - this may be an error code.
- 🟢 Constant light - normal compressor operation.
- 🔴 Flashing - standby mode or overheating protection.
- 🔵 Intermittent light - running the process of cooling a new portion of water.
- 🟡 Orange light - often indicates that the energy saving mode is on.
Some models are equipped with displays that can show error codes, for example E1 or F2. These symbols are deciphered in the technical data sheet. Most often, they indicate problems with temperature sensors or a malfunction electronic board.
⚠️ Attention: Do not ignore the flashing indicators. Prolonged operation with an error can lead to failure of expensive components such as a compressor or heating element.
Common startup problems
One of the common problems is when the cooler is turned on, the indicator is on, but the water remains warm. First of all, check whether the storage tank lid is closed. If it does not fit tightly, cold air evaporates and the system cannot reach the required temperature.
Another reason is airing of the system. Air bubbles in the tubes may prevent water from circulating properly through the heat exchanger. To eliminate this, open the cold water tap and keep it open until there is a smooth stream without “spitting” or air. Sometimes it is necessary to repeat the procedure several times.
If the compressor hums but does not start, or starts and immediately stalls, the problem may be in the start relay or low voltage in the network. In such cases independent repair of the electrical part without special knowledge and tools is prohibitedas it is life-threatening.
Operation and maintenance of the refrigeration module
For a long service life of the cooler refrigeration unit Vatten it is necessary (periodically) to carry out preventive maintenance. Once every 3-6 months, it is recommended to blow out the condenser with compressed air or carefully clean it with a soft brush to remove dust. The layer of dust acts as a heat insulator, causing the compressor to work longer and harder.
Also keep the water inlet and internal tubes clean. The accumulation of mucus or scale impairs the heat exchange between the water and the cooling element. Use only certified disinfectants recommended by the manufacturer.
If you plan not to use the cooler for a long time (for example, going on vacation), be sure to turn off the cooling mode and empty the tanks. Leaving water in the system when the power is turned off can lead to the growth of bacteria, and operating the compressor without water (if it boils away) will lead to its combustion.
Is it possible to connect the cooler to the network via a UPS?
You can use an uninterruptible power supply, but its power should be with reserve. The starting currents of the compressor are 3-5 times higher than the rated ones, and a weak UPS can go into protection.
Why does the Vatten cooler hum more than usual after switching on?
An increased hum in the first minutes of operation is normal. The compressor returns to operating mode, the pressure in the system equalizes. If the noise does not subside after 10-15 minutes, check whether the cooler body is touching the wall or furniture. Vibration is transmitted to objects, creating resonance.
How often should the compressor turn on?
In normal mode, the compressor operates cyclically. Depending on the room temperature and the frequency of water intake, it can turn on every 20-40 minutes for 5-10 minutes. If the cycle is too short (turns on every minute), this indicates a malfunction of the thermostat or a refrigerant leak.
Can the cooler be used without the cooling mode?
Yes, you can not turn on the cooling toggle switch. The water will be at room temperature. This will even extend the life of the compressor if you don't need cold water all the time. However, the heating mode (if there is one) works independently.
What does the E3 error on the display mean?
The E3 code in most cooler models indicates a problem with the hot water temperature sensor or overheating. It is necessary to let the device cool down, check the presence of water in the tank and, if the error repeats, contact service.
Do you need to defrost a Vatten cooler?
Modern models with the No-Frost system or high-quality insulation do not require manual defrosting. However, if you notice the formation of an ice coat inside the tank or on the tap, the device must be defrosted by unplugging it for 12 hours with the taps open.
