self cleaning

hi all,

need some advise on the self cleaning,

my new MHI got this self cleaning function.. how often it is recommended to do this? the manual never say or recommend any cleaning schedule or routine..

so do I need to do this every day after I off the aircon?

MHI self cleaning take 2hr to complete, it will autostart after I off the air, this function can be preset ON or OFF from the remote

I did a quick goggle on the web and notice that most newer aircon come with this features.. here is what I found from MHI

Self Clean Operation

The ‘self clean operation’ is operated for 2 hours after the unit has ceased normal operation. The indoor fan continues to operate on ultra low speed to dry the unit. This restricts the growth of mould. This feature can be selected on the remote control.

Toshiba and Daikin also have these features, just that their will only run like 20min and stop, MHI one will run for 2hr and then stop, this function can be overwrite by pressing the ON/OFF button at time during the process

if my understanding is not wrong this is not "self cleaning" as you think so.

It is just a humidifier function to help suck out humility to help prevent your room build up moisture. A useful function for those wood house oversea but for SG don't really need. Just open windows and the heat and sun in sg will do the work.

hi bro, this function is to remove the humility from the inside the aircon and the heat exchange fins, not removing the humilty of the room lah.

after whole night of aircon, the heat exchange coil and inside of the aircon and blower will be moist after you turn off, due to the sudden increase of the temperarture, so dirt, mould will build up as per normal, so by using this function, the blower will continous to blow air within the aircon to "dry" up any moisture and this will prvent or less dirt will get stuck there. also will prvent mold to build up especally on those hot day

Your one look on the ceiling still got bigger gap.
Mine from the master bedroom on the ceiling top to FCU just around 15cm around that.

Meant more high ceiling gap, can blow out more Strong airflow = more faster cooling else.
Replacing existing, still have about 28 cm of gap to the ceiling.

Nope lah, they use gas R22 or R410a flush out from the existing oil.
I saw the servicing people using water to do my Air Con cleaning during that time.

They flushed the interior and using a build in net to collect the water when it's blow out. The servicing was done by IFC that time.

But GC told me for their servicing, they will remove the whole unit and clean it.

Once remove out whole thing is good, but who can guaranty gas leak after that?

Like my sharing for apply extra filter, even over a year still can avoid they serving.

If the water dripping then just going for serving.

This one I has using an over 8 yrs already, since I found in Daiso.

But my FCU never let for Aircon man serving a once.

Internal cooling look so new & no dust at all
