2.
Install the spike on the corresponding syringe, then insert the spike into the correct fluid source. Refer to the fluid
manufacturer's instructions for use and/or package insert.
NOTE:
The system has the capability of supporting up to a 150mL bag of saline and a single patient dose contrast
bottle for hands-free fluid preparation.

To automatically fill the syringe:
a.
Press the A or B button corresponding to the syringe to be filled. The volume indicator on the injector head
displays the amount of fluid that needs to be loaded to support the displayed protocol, including the amount
necessary to prime the patient tubing.
b.
Press the +/- buttons to increase or decrease the amount of volume to be loaded.
c.
Press the A or B button corresponding to the syringe to be filled again to fill the syringe to the displayed vol-
ume. Wait 3-5 seconds for Auto Fill to complete to avoid fluid spills from spikes.
NOTE:
The Auto Fill volume for Syringe B includes the programmed injection volume, volume to run KVO for 30
minutes (if KVO is enabled), prime volume if Syringe B is configured to be used for priming, and volume to
perform a test injection (if Test Inject is enabled).
NOTE:
Auto Fill disables after 10 seconds of inactivity.
NOTE:
The system draws in the configured Auto Load Purge Volume and then expels this volume. The Auto Load
Purge volume can be set to 10mL, 5mL, or 2mL. (Instructions for setting the Auto Load Purge volume are in
"Section 15.4 - Fluid Delivery Setup" .)
4.
To manually fill the syringe:
a.
Press the Enable Piston Control button to activate the piston controls and use the reverse piston control to fill
the syringe with the desired amount of fluid. Alternatively, use the manual knob.
NOTE:
Enable Piston Control disables after 10 seconds of inactivity.
NOTE:
If protocol volume is greater than fill volume, an insufficient volume communication will display when
arming the injector.
5.
Ensure the fluid path is free from excess air.
NOTE:
If bubbles appear in the syringe, do not hit the syringe to remove them. Reverse the plunger 3 - 5 mL, then
rock the injector head on the pivot with the syringe pointed up to gather and accumulate the small
bubbles. Expel the remaining air.
