Hitachi system

[deyna]

I have a customer who wishes to move his outdoor unit, it's an RAC-25YH4 high-wall on R410a, can anyone tell me the maximum pipe run for this system. I'd be grateful if anyone can help.

Thanx

20 m for each indoor unit, Im assuming its the multi. 4 indoor units to each outdoor unit.

If you download the technical manual from the Hitachi website then you would have all the information you need to work with these units.
