5. Tighten the holding screw to secure the syringe holder position.
CAUTION Make sure the removable needle fits leak-tight to the syringe. A Teflon seal is
provided. When installing the seal, ensure that the hole is open and that no fuzzy (lint)
polymer material, which might clog the needle, is in the path. When slipping the Teflon
seal over the needle, pay attention to the sharp edges of the needle that can cut into the
polymer, which again might cause the needle to clog.
6. Move the lower needle guide carefully up and down to make sure that the needle tip does
not catch on the guide.
This section describes how to install the Valve Needle Guide assembly. Perform the
installation as illustrated in
