Hi all,

I've got an empty Eurom AC2401 mini portable split A/C.
In it, it has a "Highly" brand Compressor (model: BSA645CV-R1EN).
Now I'm just a technician/intaller, but I'm extending the length between the indoor unit and the condenser.

Currently it's about 1m (3.5 ft) long, but i want to increase that to about 4m (13 ft) max.
I've got all the tools/materials, but would you expect that it puts too much strain on the compressor? Are there rules to that?

Thanks all.
