BioOptix™ 10
Section 4 System Maintenance
4-2
The BioOptix 10 system pumps the wash fluid, flushing the
Buffer In lines, gradient formation components, pump, and purge
lines. (See Figure B-6 in Appendix B.)
4.2 Exterior Cleaning For general cleaning of the enclosure, use distilled water with a
mild detergent. Use isopropyl alcohol for tougher stains. Avoid
rubbing vigorously or using aggressive solvents like acetone on
printed areas.
CAUTION
Do not immerse the instrument in a water bath. The instrument
is not watertight and this action could damage the internal
electronics.
4.3 Piston Seal
Replacement
Should pump performance degrade, the piston seals should be
replaced.
To replace the piston seals:
WARNING
Risk of electric shock. Disconnect power before servicing.
Only trained personnel may open the case enclosure.
WARNING
Earth ground bonding connector. Do not remove or
disconnect.
1. Remove the rear cover (item 1, Figure 4-2) by unfastening
the nine screws located on the top and back of the BioOptix
10.
2. Unfasten the bottom 2 screws and rotate the valve assem-
bly up. Slide the slide lock over to catch and hold the valve
assembly.
3. Remove the upper valve assembly (item 2, Figure 4-2) by
unfastening the four screws. After removing, the valve
assembly can be rotated upward and placed on top of the
system with the cables and tubing still attached.
4. Remove the drip tray (item 3, Figure 4-2).
5. Remove the four screws (item 4, Figure 4-2) that secure the
pump assembly to the side panel.
6. Remove the pan head screw from the top mounting tab
(Figure 4-3).
7. Remove the
7
/ 64 " Allen head screw from the bottom mount-
ing tab.
8. Lift the pump assembly up and out of the case.
Note
Do not disconnect tubing or wires. They are long enough to
allow access to all sides of the pump assembly.
