You are sleeping peacefully at night. Then you are rudely awakened by the sound of dripping water. It drips continuously and won’t stop. You pull yourself out of bed to place a towel under the air con, but that merely silence the annoying drips temporarily. You know you have to get it properly fixed in the morning. But for now, at least you can steal a few more hours of sleep.
Alright, so it is morning now and you know that the leak has to fixed otherwise it will be another night of disrupted sleep. Follow these steps to clear the gel from the drainage pipes. The gel is an accumulated mixture of dust and water.
Remove the decorative cover – it usually is hung on by a clip on hinge.
Remove the plastic cage – it usually has small screws. For my Panasonic R410A, this has 4 small screws. You may need to turn on the fan coil unit to have the grilles move out of the way in order to access the screws.
Remove the grilles – this is hinged to the sides. There may be water or dirt gel along the groove, to have plenty of rags, plastic bags or a pail handy.
Locate the opening to the drainage pipe, this is usually at either end of the fan coil unit. Use a vacuum cleaner to suck up the gunk and gel. Use a small brush to clean the fins and rotating fan.
Put everything back in the reverse order. Ta- da! That’s it and you would have saved yourself $60 to $100 to the air con service man. Now you can sleep well again.
Ideally, if you use the air con daily, then clean the filters weekly. This prevents the build up of dust into the fins and minimises accumulation of gel in the drainage pipes.
