I just received a Toyo dual minisplit system (TA-12x2C(H)S/IB) and am puzzled.
The two compressors are Toshiba PA108X1C-3FZDU, labeled 208-230VAC 60Hz.
The controller circuit board doesn't seem to have anything more than the usual logic and solid state relays that would turn the compressors on and off.
Where is the DC inverter stuff done--is it hidden inside the compressor??
It would need a lot more circuitry than I can see to produce the needed kilowatts of variable frequency AC to run the compressor.
Also, the outdoor unit arrived with a lot of oil covering the compressors, driers, internal wiring; but not on the heat exchanger fins. At first I thought there must be a catastrophic leak, due to shipping damage or vibration or something, but now I'm thinking someone just made a big mess while filling the unit, and didn't clean it up. Is this common? Should I ignore it? What solvents might be safe that could help remove the sticky oil (so dust won't build up in it)? Or should I try ordinary detergents and warm water?
