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.
Thank´s for your help, I already recived these manual from you

Cleaning
the air filter
Your air conditioner�s air filter is removable for easy cleaning. A clean filter helps remove dust, lint, and other particles from the air and is important for best cooling and operating efficiency. Check the filter every 2 weeks to see if it needs cleaning. Do not operate the air conditioner without the filter in place.
For models with built-in filters 1. Unplug the power cord. (see figure 12):
2. Remove the front panel from the cabinet. (See �Cleaning the front panel� on page 12.) 3. Remove the elastic band holding the air filter in place. Then remove the air filter. 4. Wash the air filter with warm water and mild detergent. Do not wash the air filter in the dishwasher or use any chemical cleaners. Air dry thoroughly before replacing to ensure maximum efficiency.
5. Replace the filter, elastic band, and front panel. 6. Plug in the power cord.
For models with slide-out filters (see figure 13): 1. Slide out the air filter up and out the top of the
front panel. 2. Clean the filter using a vacuum cleaner attachment or wash it in warm water and a mild detergent. Do not wash the air filter in the dishwasher or use any chemical cleaners. Air dry thoroughly before replacing to
ensure maximum efficiency.
3. Slide the air filter back down in the opening in the top of the front panel.
