174 BD FACSCalibur Instructions for Use
Save the tubing to attach to the new filter.
7 Discard the old filter.
8 Install a new O-ring around the threads at the bottom of the new filter.
Push the O-ring as far up to the threads as possible.
; Tip Wrap teflon tape around the threads to provide a better fit.
9 Attach the base (from step 5) to the new filter and turn it until snug.
10 Attach the output tubing (from step 6) to the new filter by pushing the
tubing onto the output port.
11 Place the filter in the fluidics drawer with the base at the bottom and the
output port at the top.
12 Reconnect the output and input quick-disconnects.
13 Screw the air vent tubing fitting (from step 4) to the new filter’s vent port.
14 Pull the vent valve forward to repressurize the system.
15 Fill the newly installed filter with fluid.
Push RUN and push the pinchcock roller forward to allow air to escape as
the filter fills with fluid. Close the pinchcock roller when the filter is filled.
If you see bubbles, gently tap the filter body to dislodge bubbles and force
them to the top. Push the pinchcock roller forward to force the bubbles to
waste. Close the pinchcock. Repeat, if necessary.
16 Write the replacement date on the outside of the filter.
Use caution when pulling the tubing from the port. Depending on the force
with which you pull off the tubing, drops of sheath fluid can splatter. To
catch drops, cover the tubing and output port with a paper towel.
