I just want to share this problem with you , so you can be aware from that . . .
Last year we were mounting 13 AC's at Bershla " a cloth store in Kaslik Lebanon " after the team of the company finished there job we came to deliver the AC's to the owners of the shop , as I was the technical manager of the Kesserwan section in that company it was me the one who is responsible infront of the owners , we started the some ACs , suddenly I realised that ice was accumulating on 2 of the evaporators , the fans were not working , as first sight i thought that the fans power supply was broken or their control was failing . . . but after testing i realized that the problem is much bigger . . .
Guess what ?
the electricity technician wired different outdoor units to different indoor units , so the compressor of one is running but the indoor fan is in a stop condition .
I asked the technician to run the 13 AC's at the same time , the problem was solved as the 13 AC's are the same "same trade mark and model" , but would that be a radical solution , what if the owner wanted to run a defined number of AC's without the others ???? The same problem may occure depending on if the crossed wiring ACs are running together or not.
We repaired the fault and made the wirings as it should be . . .
I was a real shame for us , the Foreman was fired as well as the electrician
But beleive me , it was a real naughty situation for me infront of the customer. :eek: :mad: :(
