durst 1200 enlarger with a femocap condensers

hi,
i am looking after a college photo darkroom with mostly durst enlargers.
does anyone know where i can get a copy of a Durst 1200 enlarger MANUAL?
the enlarger has got 2 femocon condensers: 151 + 152 and a single one : 80.
i am assuming that the 151=2 are for 5X 4. does anyone know which way up they got. the 80 is for 6x9 to 6x6. is this right?
many thanks,
Brookes
