CAUTION:
The 9705 ships with the syringe drive positioned for loading a syringe. Load the syringe prior
to initially powering the 9705 .
A syringe may be loaded or unloaded with the syringe drive plunger bolt set at its top travel
point.
Each syringe has the same plunger travel distance, so this procedure allows changing to
different volume syringes. The 9705 uses syringes in these volumes:
• 1 mL
• 10 mL
• 25 mL
To load a syringe into the syringe drive:
1) Make sure the 9705 has been flushed of all fluids and the unit power is off. Make sure
the syringe drive plunger bolt is positioned at its top travel point.
2) Gently push the Plexiglas
®
door on the right of the 9705 upward to open it and gain
access to the syringe cavity.
3) Be certain that the syringe is of an appropriate size. Remove the drive bolt from the
syringe drive mechanism.
4) Fasten the syringe to the drive by bolting the drive bolt through the syringe plunger.
5) Pull up on the syringe until the lower fitting mates with the Teflon
®
fitting at the bottom
of the syringe drive.
CAUTION:
Do not overtighten the connection! Overtightening may cause Teflon extrusion and connector
degradation.
6) Twist the syringe until the connection is secure. Try to tighten so that the numbers on
the syringe face outward.
CAUTION:
When loading or removing a syringe, twist the syringe into and out of the fitting. Repeated
lateral movement of the syringe may cause damage to the Teflon syringe fitting.
7) Close the door. An error message will appear and an alarm will sound if a run is
initiated without closing the door.
