Modern water cooling systems, such as AEL, are often equipped not only with heating and filtration functions, but also with a full-fledged refrigeration module. For many users, connecting such a device becomes the first step towards organizing a comfortable drinking regime in the office or at home. However, unlike a regular kettle, a certain sequence of actions is required to activate the compressor.
Before pressing the power button, you need to make sure that the device is properly prepared for operation. Ignoring the preparatory steps can lead to breakdown of expensive equipment or incorrect operation of the thermoregulation system. In this article, we will analyze in detail the process of starting, setting temperature conditions and solving typical problems faced by owners of coolers AEL.
Primary preparation and installation of equipment
Any cooler with refrigerator requires correct installation before the first turn on. The device should be located on a flat, stable horizontal surface away from direct sunlight and heating devices. The distance to the walls should be at least 10-15 centimeters to ensure free circulation of air around the heat exchanger. If you ignore this requirement, the cooling efficiency will drop sharply, and the compressor will work with overload.
After installing the water bottle, you must wait a certain time if the device was transported in a horizontal position. Oil in the compressor may have leaked into the refrigerant circuit and requires rest to return to the crankcase. Typically, manufacturers recommend allowing the device to stand in a vertical position for 2 to 4 hours before connecting to the power supply.
⚠️ Attention: Never plug in the cooler if it has just been brought in from the cold or is very cold. Sudden temperature changes can cause condensation on electronic boards, resulting in a short circuit. Allow the device to warm up to room temperature for 3-4 hours.
Make sure the water supply taps are closed and the bottle is securely fixed. The air from the system should escape naturally through taps or special valves when the tanks are first filled. Only after you are convinced that there are no leaks and a stable water level, you can proceed to the electrical connection.
The procedure for turning on and activating cooling
The process of activating the refrigeration module on coolers AEL has its own characteristics. Unlike the heating function, which often operates immediately after power is applied, cooling system may require manual start or have a built-in delay to protect the compressor. There are usually two switches or buttons with corresponding indicators on the back panel of the device or on the front control panel.
The first step is to turn on the device to the network. The power indicator on the control panel will light up. Next, you need to find a switch with a snowflake symbol or the inscription “Cool”. On some models AEL this switch is hidden under a protective cover or located on the back wall next to the network cable. Move it to the "I" (On) position.
☑️ Check before starting
After activation, you should not expect to instantly receive ice water. The compressor requires time for the first cooling cycle of the full volume of the tank. On average, primary cooling takes from 40 minutes to 1.5 hours depending on the tank volume and ambient temperature. At this time, the device may emit a characteristic hum - this is the normal operation of the refrigeration unit.
Setting temperature modes and control
Modern models AEL allow the user to flexibly adjust operating parameters. Control can be carried out either by mechanical toggle switches or by an electronic touch display. Understanding the logic of operation thermostats will help you optimize energy consumption and extend the life of the device.
If your cooler is equipped with electronic control, switching to the setup mode is usually accomplished by long pressing the "Set" or "Menu" button. In the menu you can set the target cold water temperature, which usually ranges from +5 to +15 degrees Celsius. For office premises, the optimal value is +8...+10 °C.
⚠️ Attention: Do not set the minimum possible temperature (+4...+5 °C) in hot rooms without good ventilation. This will force the compressor to work almost non-stop, which will significantly reduce its resource.
Hidden energy saving mode
Some AEL models have a hidden Eco mode. To activate it, press and hold the "Hot" and "Cool" buttons simultaneously for 5 seconds. In this mode, heating and cooling are turned off at night (from 22:00 to 07:00), saving up to 30% of energy.
Also worth paying attention to is the child lock feature, which is often activated automatically when you turn on the cooling mode to prevent accidental scalding. Unlocking a hot water tap usually requires double pressing or simultaneously pressing two buttons.
Indication and interpretation of signals
The cooler control panel AEL is equipped with an LED indication system that reports the current operating status. A green light next to the snowflake means that the cooling mode is active and the water temperature corresponds to the set temperature. If the indicator is flashing, this indicates the cooling process - the water has not yet reached the desired temperature.
A red indicator or flashing symbol can indicate various system conditions. For example, flashing often indicates that the water in the bottle has run out or the pressure in the system has dropped. In some models, a flashing heating indicator when the cooling is on may indicate overheating of the tank or a malfunction of the temperature sensor. (lit) temperature sensor.
| Indicator | State | Meaning |
|---|---|---|
| Green (lit) | Cooling mode | Water is ready for drinking |
| Green (flashing) | Process | Water cooling in progress |
| Red (lit) | Error/Heat | System check required |
| No light | Off | No power or sleep mode |
Important to monitor the behavior of indicators in the first hours of operation. If the light continues to flash after 2 hours of operation and the water is not cooling, there may be a problem with the refrigerant or thermostat. In this case, a more in-depth diagnosis is required.
Typical startup problems and their solution
Even when turned on correctly, users may encounter situations where the cooler AEL does not cool the water. One of the most common reasons is insufficient operating time. As mentioned earlier, the first cycle can take up to an hour and a half. If more time has passed and there is no result, check whether the taps are tightly closed.
A constantly open or dripping cold water tap leads to the fact that warm water from the bottle constantly flows into the tank. The compressor simply does not have time to cool the entire volume, creating the illusion of a breakdown. The problem may also lie in contamination of the heat exchanger with dust, which is especially important for devices installed on the floor.
Another reason is a malfunction of the compressor start relay. This happens when there are frequent power surges in the network. If you hear a click when you turn it on, a hum that ends abruptly, and a second click after a minute, most likely the problem is in the starting device or the compressor itself.
⚠️ Attention: Self-disassembly of the refrigeration circuit and an attempt to refill with freon is strictly prohibited without special equipment and a license. This is dangerous to health and will completely disable the equipment.
Prevention and care of the refrigeration module
In order cooler with refrigerator to serve for a long time, it is necessary to regularly carry out preventive measures. It is recommended to clean the rear radiator grille of dust and pet hair at least twice a year using a vacuum cleaner or soft brush. A radiator clogged with dust is the main reason for overheating and compressor failure.
It is also important to keep the internal tanks clean. Although the cooling system is closed, when changing bottles, contaminants may get inside. Periodic sanitation of internal containers with special means will extend the life of not only the refrigerator, but also your health. Use only certified products for processing food containers.
Do not forget to check the tightness of the bottle to the receiving socket. If the bottle neck is damaged or has a non-standard size, air can be sucked into the system, disturbing the hydraulic balance and creating a load on the pump and cooling system.
Frequently asked questions (FAQ)
Why does the AEL cooler hum only at night?
This is due to the fact that at night the room becomes quieter and the background noise of the compressor becomes more noticeable. In addition, at night the voltage in the network may drop, which changes the nature of the operation of the electric motor. If the humming has changed to knocking or grinding, this is a sign of a malfunction.
Is it possible to turn off the cooling at night?
Yes, this is even recommended to save energy and reduce equipment wear if water is not used at night. However, turning it on and off (every day) may be more harmful than constantly working in maintenance mode. It is optimal to turn it off on the weekend.
What to do if the water becomes warm, although the indicator is on?
Most likely, the thermostat has failed, which “thinks” that the water is cold and does not turn on the compressor, or a refrigerant leak has occurred. Also check if the cooler is located next to the battery or in direct sunlight.
How long does it take for the water to cool down after replacing the bottle?
After replacing a full bottle (19 liters), the system requires from 40 minutes to 1 hour to completely cool the volume to the set temperature, provided that the device has already been warmed up and was in the mode expectations.
Is it safe to use an extension cord for a cooler?
You can only use an extension cord if it is designed for a power of at least 2 kW and is grounded. However, manufacturers AEL recommend connecting the device directly to an outlet, since the starting currents of the compressor can heat up low-quality extension cords.
