Do De’Longhi portable air conditioners need to be drained?

De’Longhi portable air conditioners do not need to be drained often, because of their No Drip Technology, but there are some circumstances where they need to be drained.

Air conditioners cool down and dehumidify the air in your space and this is why moisture can accumulate within the unit.

De’Longhi portable air conditioners are made with “No Drip Technology”, but they still need to be drained from time to time, like all other portable air conditioners, when there is high humidity.

Why does moisture accumulate in air conditioners?

Air conditioners (AC) allow you to make the spaces where you live, work, and entertain much more comfortable.

This is because air conditioners have dual functions, they cool the air in the room to actually lower the temperature of the space, but in doing this, they also remove excess heat and moisture from the air in your space.

This means that air conditioners cool and dehumidify air at the same time. This excess moisture which is removed from the air in your space collects in the air conditioner and is known as condensate.

Do De’Longhi portable air conditioners need to be drained?

All air conditioners accumulate moisture over time. Some types of air conditioners, like window air conditioners, let this accumulated condensate drip into a condensate pan which is tilted so that it can drain out on the outside of your home.

Central air units move moisture to the outside of your home via a condensate line. However, portable air conditioners have no condensate line with which to transfer the excess moisture outdoors.

This means that portable air conditioners need to be manually drained to get rid of this accumulated moisture.

Most of the De’Longhi portable air conditioners, including the PACEX390LVYN, EL376HRGFK, PACEX370LN, PACC100EC, and PACN285GN models, include the brand’s No Drip Technology.

This means that these De’Longhi portable air conditioners turn the condensate into vapour and this vapour can then be expelled through the exhaust vent.

However, if you live in an area with high humidity levels or your De’Longhi portable air conditioner is near high-humidity areas in your home, moisture will still accumulate, even with this No Drip Technology, and you will have to drain the portable air conditioner.

Fortunately, there are several ways to go about draining your portable air conditioner if this is the case for you.

Your De’Longhi portable air conditioner should give you a warning that it needs to be drained when the condensate tank becomes too full, but it is important that you keep the air conditioner as dry as possible, even when this warning is not displayed yet, as this will help you avoid any bacteria or mould and mildew growth in the unit.

How to tell if you have high humidity

When you live in an area where the humidity is high, or the steam from your shower or kitchen is regularly taken in by your De’Longhi portable air conditioner, you definitely need to drain your unit often.

You can use a humidity gauge, like this ThermoPro TP50 Digital Hygrometer to measure the relative humidity of the space that your De’Longhi air conditioner is in. Ideally, the indoor humidity of your space should be about 30 percent to 35 percent.

If the relative humidity in your space is higher than 60 percent, you need to drain your air conditioner manually, as the No Drip Technology will not be able to convert all of this moisture into vapour.

The different ways to drain your De’Longhi portable air conditioner

Even if you do need to drain your De’Longhi portable air conditioner more frequently, there are a few ways to go about this and the process should not be too complicated.

You simply need to find the drain port at the back of your unit near the bottom. Then, you can remove the drain plug and let the accumulated moisture run into a bowl.

Alternatively, you can connect a drain hose to the drain port, which will allow your portable air conditioner to drain into a floor drain, while connecting a condensate pump to your unit can automate the process entirely.

Why it is important to drain your De’Longhi portable air conditioner

It is important that you drain your De’Longhi portable air conditioner when it gives you a warning that the condensate level is high, or before you store it at the end of every winter season.

This will help you avoid any bad odours or health hazards that may pose a danger when bacteria and mould or mildew grow within the unit when the moisture has stood still for too long. This also means that your unit will not accidentally spill over when you use it.
