so i see... indeed it is a product issue, too strong a compressor and too small were the blowers that the Cold wasn't efficiently channelled away and so the pipes leading to and away from the blowers are both cold. Condensation on the pipes led to sweating. I was using 1/2 inch insulation yet it didn't help.

so paranonia was i that i asked for 3/4 inch insulation for my next Air-Con to be installed next week.

good thing you didn't repair it... hee
wah u use 1/2 inch arh? sibei kiasu leh.. i bet ur new trunking is smaller now.. anyway my friend commented the MA56EV1 outdoor unit is best linked to 3 FCU.. if 4 FCU on at the same time.. the cooling will suffer by 50% tats if i on all 4 FCU at the same time... i'm not too sure whether its true or not, but getting another inverter Daikin which will cost me $3200 for an R22 refrigerant type. which is more than twice the amount i'm paying for non-inverter.. =\

I guess i haf to suffer this fate.. maybe 10yrs down the road.. i will den get an inverter.

R410 type of refrigerant is too ex to maintain, and outdoor unit is not cheap also! wads more if 1 day lightning strike on my outdoor unit... i will prepare to fork out high amount of cost of repair AGAIN!

ai yo... where got so suay one? strike lightning?

btw, mine new one isn't 1/2 inch hor... it is 3/4 inch! Now that's what i call kia-su lor!

Even then, GC also cannot guarantee that the trunkings won't sweat... i wanted to go 1 inch okay! And the sales person was looking at me with a stunned look!

I think it's all the same lah... most system-3 and system-4 uses same compressor, so of course if you switch on all 4 rooms, it'll be weaker lah... but i think it's okay one lah.

yup..MA56EV1 link to 3 is gd. but if link to 4th one than of cos will reduce. but depends the 4th one is 9000btu or 18000btu. for my case, is system 4. 3 x 9k + 1 x 18k. i dont tink ppl will on all la.. cos for mine, 4th one is living room. normally all wil be at the living room, so on all the 3 also no use. so is either on 18k one or 3 x 9k.

but to the thickness of insulation, normally 3/8 works fine for all ba. unless is product problem, than thicker also no use.

aiyo! i never heard b4 outdoor unit wil kana lightning sia!

After contemplating for a few weeks, i finally decided to get system-2 Inverter Mitsubishi Electric from Hong Tar. They finished the installation about 3 hrs ago. The 2 guys who did the installation were pleasant and answered all my queries.

So far so good.
They first set it at 23 celcius. Was quite cold. I'm settling with 27 celcius for now.

Fixed up Daikin MA56EV1 and 4 FCU yesterday.. used back all the drainage and piping..

frankly speaking i feel its way better than Fujitsu.. though now it takes longer time to cool the entire room.. nevertheless the money its well spent.
