View Full Version : Vrv 3 piping distances

02-03-2013, 06:50 AM
starting 3 pipe system on an install next week with 3 outdoor units and 11 indoor units with bs boxes.
I would like to know what maximum pipe length can you have from the refnet / bs box to the indoor unit?

Allways believed it to be max 5m but apparently it can be whatever you want according to daikin as long as the pipe is sized correctly

Ive looked in the manual and it is not clear about the distances from bs box to evap..
You must have the manual to hand..?
