DeLonghi – an Italian leading-edge company equipped with modern tools, known for manufacturing a range of appliances for both commercial and domestic sectors. In 2025, they’re producing portable air conditioners with a range of unique features and benefits, famous for 4 in 1, including cooling, heating, dehumidifying, and ventilation. The Pinguino air conditioner series is renowned for its energy efficiency, Real Feel technology, Arctic Whisper, and portability.
With careful maintenance, they require timely and regular drainage. Some portable air conditioners have auto functionality that removes water through an evaporative process. But many of them need manual draining practice. Whether at home or in the workplace, you need to do it very professionally as possible. In this blog post, you'll find a complete guide to draining the extracted water.
How To Drain Your DeLonghi Air Conditioner?
Depending on the AC model, the collected water needs to be drained. If the model has a manual system, it requires manual action; otherwise, it will evaporate on its own. Manual and automatic, these are drainage systems present in the AC. Here is a complete guide on how to drain your DeLonghi Air Conditioner in 2025:
Manual Drainage Method:
- Read the instructions in the manual carefully, as every model has its system.
- Unplug the switch and make sure your unit is turned off, then turn it around.
- At the bottom of each air conditioner, there is a small drain cap.
- Place a small container at the back and open the drain cap.
- Water will begin to flow, and keep it open until all the water is sure to drain out.
- Tilt towards the drainage hole at 45 degrees to ensure no water remains inside.
- After this, make sure to close the drain cap tightly.
- Re-plug it and enjoy your fresh air.
Automatic Evaporation:
Some modern models have an auto-evaporative system to remove water via the exhaust hose. Mostly, it comes in dehumidifier models, where water needs to cool down the condenser and then be expelled. This eliminates the need to drain the water manually.
When You Should Drain DeLonghi Air Conditioners?
Let’s reveal the concept behind the reason for draining. DeLonghi air conditioners collect water from the surrounding air, which we term as air humidity or air moisture present in the atmosphere. The water used to condense inside the unit accumulates.
Specifically, DeLonghi indicates a drain needs to be displayed as “HL”. Moreover, do it timely at the end of each season, at least once or twice. Depending on the environmental humidity or moisture percentage, we recommend checking regularly how quickly it fills up. In case of HL display or overflow, immediately turn off your air conditioner and properly follow our guide to drain the machine. This is part of specific tasks that affect the overall longevity of the machine and prevent shutdowns or leaks.
Important Considerations Before Draining DeLonghi AC
There are some crucial things to do before, during, or after draining the air conditioner. Keep them in mind and read them very carefully. Here are these:
- Before draining, make sure electricity is cut off from your unit and it’s unplugged.
- During draining, ensure the container is positioned under the drain pipe at an angle, allowing gravity to facilitate proper drainage.
- A condensate pump can be used to expel water through the window side if the drain cap is not opening or causing a problem.
- After draining, ensure the drain cap is tightly closed, like a seal, and that there is no water left inside or around the air conditioner to prevent any harmful electrical accidents.
What if You don’t Drain?
Portable air conditioners, including Pinguino models, need some careful upkeep. If you don’t have the time to drain promptly and correctly, it can cause serious issues. It can lead to overflowing, water damage to the machine as well as the surrounding area, and even shut down the unit. Some notices indicate that moisture can cause mould growth inside the unit and cause electrical problems. So be careful and do it on time.
Conclusion
Proper drainage helps to keep your appliance well-maintained and works efficiently with an increased durability or warranty. No doubt, DeLonghi air conditioners are among the best appliances. However, it needs proper and careful maintenance. Read the up-to-date guide about draining carefully practices above, and ensure you drain as professionally as possible.
