Remove shipping fluid from the Pump
1. Using aseptic technique, open the Pump sterile package. Do not remove the
plastic tubing from the Pump outlet. Trim the distal part of the tubing with
the scalpel blade.
2. Remove the refill syringe from the refill kit package.
3. Firmly attach the two-way stopcock to the refill syringe and attach an 18
gauge needle to the stopcock.
4. Draw approximately 4 mL of RINSE BUFFER into the refill syringe.
5. Fill the hub of the refill needle with RINSE
BUFFER and firmly attach it to the
stopcock, prime the needle and close the
stopcock. (See Figure 6.)
6. Retract the plunger until it locks into place.
This should be no further than 55 mL. Do
not go beyond the vent hole. Press the lock
into the plunger groove to be sure it is firmly
secured.
7. Fill one 3 mL syringe with RINSE BUFFER
(RB) and attach a needle.
8. Fill the Pump fill port using the 3 mL
syringe. Any time a refill needle is to be
inserted into the Pump fill port, a fluid
barrier must be present to prevent air from
entering the Pump reservoir.
9. With the stopcock still closed, insert the RB
syringe into the Pump fill port.
10. Open the stopcock and allow the syringe
vacuum to empty the Pump of shipping
fluid. Allow 30 seconds after the fluid level
appears to have stopped rising in the refill
syringe, to assure the Pump is completely
emptied. Close the stopcock and remove the
syringe.
