Hello Chaps

I've got a question about the L'unite Tandem Compressor TAGD 4610Z with a Henry Oil Separator.
TAGD 4610Z is equped with oil and pressure equalization tube between two compressors. I would like to know if I can simply conect to this equalization tube a return pipe from the oil separator. Could it be a reason of any problems or dangers?

Many thanks
