I have been using a Daikin 1.5HP Inverter (FTKD-35GVM) for about 7 months now. So far so good.

Cleaned the two filters quite regularly but still the fan rotor is always the dirtiest part of any aircon. Getting the tech to come clean it can cost quite a bit so been able to clean it yourself is a big plus. Taking out the fan rotor is a daunting task for me and so I took the easy way out by just vacuuming the fan blades. Usually these are block by those vertical and horizontal airflow blades but I found they can be remove quite easily. Happy to say I was able to remove 80% of the grime stuck to the fan blades with not much trouble. I know some brands allows easy access and some brands, you cant really do much. Thank goodness, this Daikin model allows that even though its not suppose to be an end user job

I will post a series of diagrams for you to follow below. Just be careful not to probe too hard with your vacuum crevice tool, you dont want to break any of the fins from the fan rotor. My vacuum brush tool was too big to enter the space. A brush would really help.

1. First remove the Horizontal Blades. The little shafts can drop out so take care or you will lose them. When installing it back, make sure the right side goes in first as it is keyed.


2. There are 5 clips holding down the Vertical blades. 3 at the back and 2 in the front. The 3 plastic hook at the back needs some prying using a flat blade screwdriver.


3. The front 2 catch can be easily unhook by bending the soft plastic blades.

Once you get these out, you can easily access the fan rotor with your vacuum cleaner. Make sure not to probe too hard as you might break a fin blade.

Btw I set my temp around 26C at night from 8:30pm to 6:30am (about 10 hours), with some TV viewing, a PC or two running. Usage is 4-5kHW per night I am getting. When I first started using this aircon, I had to set around 25C to 26C but lately I found it too cold at 25C and I can go up to 26C-27C.
