W A R N I N G
Because of the high voltages in the centrifuge, untrained personnel must not attempt any repair or
replacement procedures. To reduce the potential of electrical shock unplug the centrifuge power cord before
proceeding unless otherwise specified.
Be sure that user has performed appropriate decontamination procedures as outlined in paragraph 1-2, before
attempting any repair or replacement procedures on the centrifuge.

5-1. Latch Replacement
NOTE
Retain all hardware for reassembly unless otherwise
advised.
1. Open chamber door.
2. Turn centrifuge power off and unplug power cord.
3. Remove the two phillips screws located on each side of the
bezel. Carefully lift the bezel up to disengage it from the frame
(but do not disconnect).
4. The latch assembly is installed on the Latch/P.C. Board panel
using mounting hardware (two nuts at the top of the bracket
and two phillips screws at the bottom of the bracket). Remove
the latch mounting hardware - the nuts require a 7 mm wrench.
Refer to figure 5-1.
NOTE
Do not remove the two phillips screws located in the
center of the latch assembly bracket — these screws
secure the latching mechanism to the bracket, and
must
not be loosened.
5. Disconnect P231, then remove and discard the defective latch
assembly.
6. Install new latch assembly securing it in place using the hard-
ware removed in step 4. Before tightening the hardware, adjust
the latch assembly following the procedure given in para-
graph␣5-2.
