5-18 Troubleshooting the Analyzer
CAUTION
To avoid getting fingerprints on the glass windows of the flowcell, always
hold the flowcell by the metal slides.
Cleaning the Flowcells off the Analyzer: Step 2
Taking the Flowcell Apart
1. Unscrew the locking nut (
1
) at the input end of
the flowcell assembly.
2. Using a twisting motion, remove the CFM (
2
)
from the flowcell.
3. Be careful not to lose the O-ring seal (
3
).
Cleaning the Flowcells off the Analyzer: Step 3
Cleaning the CFM
1. A pin vise ( 1 ) and a 1/64-inch (0.4 mm)
diameter drill bit ( 2 ) are supplied in the
Flowcell Cleaning Kit. Open the pin vise, insert
the drill bit approximately 1/4 inch (6.4 mm)
into the vise jaws, then tighten the pin vise.
2. Insert the drill bit into the sheath nipple ( 3 ).
Using a twisting motion, carefully push the
drill bit through the sheath nipple. If a clog is
encountered, proceed slowly while continuing
to twist the drill bit.
3. Repeat step
2
for the sample input nipple (
4
).
4. Carefully insert the bit into the shuttle nipple
(
5
) to a depth that just barely leaves the flutes
of the bit extended beyond the end of the
nipple. Twist the drill bit a few times, then
remove it from the nipple.
