Syringe Loading – 4 x 140 & 6 x 10 Multi-Racks
Figure 78: Front view of PHD ULTRA
™
showing controls for multi-rack syringe loading.
1. Raise or remove Clamp Bar (7) by unscrewing thumb screw.
2. Loosen T-Knobs (8) and slide the Retaining Bracket (4) on the Syringe Holder (3) open.
3. Adjust the Pusher Block (2) to the approximate length of the syringe(s) by squeezing the Release Tabs
(1) and sliding the Pusher Block into position.
4. Loosen the three thumb screws on the Anti-Syphon Bar (5) to provide enough room for the plunger
flange of the syringe(s). If using the 6 x 10 rack, loosen the two thumb screws on the outside of the
Plunger Holder (11). Lift the Plunger Holder and then tighten the thumb screws so it remains at its
maximum height.
5. Place the syringe(s) on the Syringe Holder (3) ensuring that the barrel flanges are within the Syringe
Holder’s Retaining Bracket (4) and the plunger flanges are between the Pusher Bar (6) and Anti-
Syphon Bar (5).
6. Push the Syringe Holder’s Retaining Bracket (4) tight against the barrel flanges and tighten into place
using the two T-Knobs (8).
7. Tighten the Anti-Syphon Bar (5) using the three thumb screws. If using the 6 x 10 rack, lower the
Plunger Holder (11) and secure by tightening thumb screws.
8. Lower or replace the Clamp Bar (7) and tighten thumb screw until Clamp Bar is firm against
syringe(s).
9. Squeeze the Release Tabs (1) and move the Pusher Block (2) to the right until the syringe plunger is
located as far into the syringe as it will travel.
10. Using the Allen Wrench, located in its holder in the rear of the Pulley Cover (12), loosen the Infusion
Mechanical Stop (9) and slide it to the left until it is in contact with the Pusher Block (2). Use the
Allen Wrench to tighten it in this position.
✐
NOTE: If using fewer syringes than the maximum number of syringes, try to place them
symmetrically about the lead screw to present a balanced load.
