Turns out this was not the manual i was looking for. The concertmate 670 keyboard i have is a "Realistic" model made for Radio Shack and none of the diagrams on the owners manual i received matches up. HOWEVER, I must say the service Owners Manual provides was fast and efficient by being available online. The manual was in good readable condition and easily downloaded.
ThankΒ΄s for your help, I already recived these manual from you

Drill two holes Ã 8mm and fix the support bracket with two wall plugs and screws (3). The wall plugs, if supplied, are for Fig. 7 brick or solid block fixings only, excluding thermal blocks and similar. For mounting on any surface other than brick, the correct fixings must be used. Hang the hood (4) and adjust its position (5-6). From the inside of the hood mark two points for definitive fixing (7). Remove the hood (8) and drill two holes Ã 8mm (9), fit two wall plugs (10). Drill two holes Ã 8mm on the upper side close to the ceilling, fit two wall plugs (11) (In case the hood is to be used in recirculation mode, mount the deflector F on the chimney support with four screws 2,9x6,5 and fix the chimney support G with two screws (12). Hang the hood again (13) and fix it definitively with two screws (14). Fit an exhausting pipe (15) to connect the outlet hole A of the hood to the outside (Extractor hood) or to the deflector F (recirculation mode). Make electrical connection (16). Fix the chimney first up (17a) to the chimney support (17b), then slide the lower section of the chimney down into the proper housing on top of the hood (18).
