Set-Up and Installation
Air Source
COMPRESSED AIR
To begin working with the Ultima 250 dental unit using an air compressor, you will need ¼ outside
diameter tubing. Cut the ¼” tubing to the length needed between the compressor and where the
unit will be used. Connect the male quick disconnect fittings provided with the unit to the ¼” tubing,
connect the male quick disconnect without shut-off to the compressor. Run the tubing to the unit
from the compressor and connect the male quick disconnect fitting with shut off valve to the female
quick disconnect fitting on the side of the unit labeled Filtered Air In. Set the air pressure from the
compressor to 70 Psi. NEVER EXCEED 80 Psi GOING INTO THE UNIT!
*If you are using a compressor that is not an Ultima Silent-Surge compressor then additional parts
and fittings may be required. For additional parts contact your local distributor or UDS Technical

Place the tubing through the collar on the male quick disconnect fitting provided. Slide the tubing
onto the metal barb on the back of the male quick disconnect fitting. Screw on the collar to the back
of the male quick disconnect and tighten.
