Air-con Fcu Insulation

[Jliow 0]

Hi recently installing Aircon saw that my contractors were putting the coolant and return copper pipes into one insulation tube near the FCU area, the rest of the pipes are individually insulated. is that normal?

I was thinking the pipes should all be individually insulated all the way into the FCU

Can someone advisse?

shd be individually insulated. Some are hot pipes, some are cold pipes. Putting together will result in massive sweating.
