Draining your LG portable air conditioner should be done carefully and is critical for avoiding issues of overflowing, especially when moisture levels are high.
Portable air conditioners operate by extracting moisture from the air to efficiently cool a room down. Some units need moisture to operate but when the portable air conditioner’s water tank gets full, it needs to be emptied for the unit to continue operating accordingly.
For people with an LG portable air conditioner, LG has recommendations on how to safely go about draining the condensation water from the unit to keep it in good working condition. Following LG’s guidelines will help owners of these portable units drain their tanks.
Draining LG portable AC units
Different weather climates will determine whether you have to drain your unit more often or not too frequently. If you live in an area that is humid relatively more often for long periods, your portable LG air conditioner will extract and get rid of quite a lot of water to be able to cool your space effectively.
The more water is collected in the unit, the faster the drain pan or water tank will fill up and the more often you will have to manually drain the unit.
How to drain an LG portable air conditioner
Different portable models have dissimilar methods of drainage. Some units have a drain cap located at the bottom of the unit, while others have a drain plug where water flows out.
No matter the type of drainage system you have, you need to know how to drain your unit.
Start by switching off the unit and unplugging it from the wall outlet, then remove the vent hose assembly to locate the drain port at the back of the unit.
If the unit needs to be drained into a container, carefully lift the unit to place it on a stable platform, turn the drain cap counter-clockwise and remove it, and pull out the drain plug carefully to allow the water to start draining.
Once draining is complete, remove the container and dry any wet areas. After removing the drain cap, you may need to tilt the air conditioner slightly to allow for any excess water to drain.
On some units, there is an outer and inner cap that must be removed, use a shallow pan to drain all the water from the unit. Once all the water has been drained, reseal the drain cap securely to avoid water leaking.
Do all portable units need to be drained?
Not all portable air conditioners have to be manually drained, thanks to the advancements in air conditioners.
Some newer, modern, portable units have a dedicated exhaust hose through which accumulated moisture is vaporised and released via the exhaust hose that connects to the window and releases the moisture outside.
Investing in such units can be advantageous if you want to avoid manually draining the unit. It can be especially useful for people who may often forget to drain their AC unit.
How often do you need to drain the air conditioner?
How often you need to drain an LG portable air conditioner unit varies depending on the temperature of the room it is operating in and the amount of moisture that needs to be extracted.
If the climate is very humid, you will have to drain the unit more often as high humidity means water is filling the unit at a rapid rate. Time between drainage can range from two to eight hours but varies based on the capacity of the portable unit.
Why your portable AC needs to be drained
A few things can go wrong if your unit is not drained often enough. The unit can shut off and not turn back on, particularly if it has a float switch that switches the unit off when the condensate tank is full.
You run the risk of the condensate tank overflowing if the float switch is not working, which can cause issues for the unit and for your home. If water is left inside the unit, it can become a breeding ground for mould to grow, due to moisture.
