Front cover : Helps to keep the Return Flow Controller’s internal
mechanism clean, and graphically illustrates operating modes.
Front cover thumb nuts : Hold the front cover in place. Remove the
front cover to clean the inside of the Return Flow Controller. See
“Disinfecting” on page 10-4 for instructions.
IV pole mounting clamps : Attach the Return Flow Controller to the
horizontal or vertical segments of the IV pole. (See Figures 3-1 and 3-2
in Chapter 3, “Installing, Transporting, and Returning the Spectra
System.”) For instructions on how to install the Return Flow Controller
on the IV pole, see “Return Flow Controller Installation” on page 3-2.
Return flow indicator : Indicates the current return flow position on the
return flow scale.
Return flow scale : Shows pressure at which blood components return
(withdrawn during a Single-Needle Draw phase) to donor/patient. On
the scale, 0 is the minimum or “low” flow setting, and 7 is the maximum
flow setting. See Figure 2-9 for a view of the return flow scale set to 3.
Figure 2-9: Return Flow Controller set to 3
Return flow guide : Helps determine the direction in which to turn the
flow controller hand crank. As you turn the crank clockwise to increase
the return flow rate, the red triangle in the left return flow guide window
widens. As you turn the crank counterclockwise to decrease the return
flow rate, the red triangle narrows.
Bag load indicator : Indicates the Bag Load position. When the flow
control handcrank is at the counterclockwise stop, a red arrow appears in
the clear window, indicating the Return Flow Controller is in the bag
load position (see Figure 2-10).

Prime position indicator : Indicates the prime position. When the flow
control handcrank is at the clockwise stop, the red arrow is at the top of
the window, indicating the Return Flow Controller is in prime position
(see Figure 2-11).
Flow control handcrank : Turns to set the Return Flow Controller in the
Bag Load and Prime positions and the return flow in the proper position
(see Figures 2-10 and 2-11).
