4. Connect the Model 527 phantom to the pumping system as shown on the above diagram.

5. All of the flow channels need to be filled with test fluid to avoid an air-phantom interface.

6. When you are now ready to prime the pumping system and fill the flow channels,  turn the
"Speed Dial" on the pump driver to "0". Turn on the pump. Slowly increase the speed of the pump
to achieve the desired fluid flow.  Allow the pump to run until it is completely primed and no visible
air-bubbles are seen in the tubing.  When is accomplished, turn the "Speed Dial" back to "0".

7. Disconnect the pair #1 flow channel and replace the luer-lock plugs, to prevent the fluid from
leaking out of the channels.

8. Repeat this procedure for the remaining flow channel pairs.

NOTE: In the operation of any flow phantom it is likely some air bubbles will enter the fluid stream; 
either through cavitation in areas of expanded diameters or entrainment of air at a fitting or 
connector. For these reasons a large reservoir is required. As the pump begins to circulate the test 
fluid through the system, entrapped air bubbles will enter the fluid and be pumped into the return 
side of the reservoir.

9. Select the desired flow channel pairs for testing. Use the procedure above to connect the flow
channels to the pumping system.  If greater edge-to-edge distances are required, a combination of
two flow channel pairs can be used as illustrated in Figure 2.

NOTE: THE PRESSURE OF THE FLUID DELIVERED TO THE PHANTOM MUST NOT EXCEED 
8 psi (POUNDS PER SQUARE INCH). IF FLUID PRESSURES ARE USED IN EXCESS OF 8 psi 
THE PHANTOM WILL BE PERMANENTLY DAMAGED.

The phantom is now ready for performance testing.
