Be sure to REMOVE the waste
container after internal
priming. Otherwise the door
can not be closed and this
will prevent the PHERAstar
FS from performing a test run.
External priming
requires that the needle holder and the magnetic clamp are removed.
To start priming, place compound solution in the compound vessel and insert the tubing into the solution.
Pull away gently the magnetic clamp and remove the needle holder from its normal operating position. Hold
on to the needle holder and place an external waste container (beaker) underneath the needle. Priming is
then initiated either via the Control Software or the respective priming buttons by a double click (figure 29).
External priming is mostly used for cleaning the tubing and to check if the solution comes out strait out the
needle tip. If the fluid jet is coming out in an angle this is indicative that some debris is partly clogging the
needle tip. Thus cleaning of the tubing and the needle is required. Refer to chapter 4.6.1
for the cleaning
procedure.
External Priming Step 1: Pull away the Magnetic
