Hello, Im new to this forum. I have a brand new small R22 Fuji rotary (on/off) compressor which I intend to use for 407C and therefore an oil change to Ester type is neccesary. Can only drain oil (~300ml) out of a hole I drilled close to the connection (HP) non from the suction line (muffler is removed). From what I have read there should be some oil also in the lower (suction) part or...?
