Step 9 (cartridge base)
Unscrew the tightening screw with the help of the
MDT 327 (counter-clockwise). Remove the
tightening screw and the cartridge base from the
fluid box.
Important note!
If you use a Cartridge Base CH, you need to screw
off the Fluid Box Connector Luer Lock first. Use the
open-jawed wrench at the side of the MDT 327
(hexagon screw size M8).
Step 10 (O-ring)
Remove the O-ring from the fluid box body. Pull it
off carefully with a pair of tweezers. Be careful not
to damage the O-ring.
Caution!
You could omit this step, only if the solvent you
use is compatible with the material of the O-ring.
Unusual (connector BY)
Usually you will not remove the Connector BY and
the fluid box body. In case the connector is
clogged, use MDT 327 to screw off the Connector
BY (counter-clockwise). Then pull out the fluid box
body.
