Carrier Xarios 300 Info

[Tayters]

Has anyone got any info on these?

Not my normal cup of tea but played around with one last week. Was after a pipe schematic just to be better informed as couldn't quite workout what was what.

System had standby and engine compressors. 3 pipes from engine compressor, 2 pairs of pipes in evaporator (at least I could work out those!) then a check valve and reciever jobbies up top. Couldn't quite suss out how and where the refrigerant flowed. Figured out hot gas defrost but amongst other thing why 3 pipes from compressor?

Tried the normal routes but can only find a spares listing.

Thanks,
Andy.
