Hitachi RAM-18CZ1 Outdoor unit
I have been asked to re-install one Ram18 to 2 RAS9's.(an old r22 system)
By looking at the electrical connections, it appeares that the outdoor unit has each of its compressors fed by a 13 amp supply from the indoor unit.
Sorry if this is a daft question, but i havn't seen it done like this before.
Is this correct ?
If so, and they are totally independant circuits, do you have simultaneous haeting and cooling ?
The RAM-30 CW1 that is the same age and also needs re-installing, has the more conventional 30a to outdoors, then powered interconnections.
Am i missing somthing ?
cheers
