Place the supplied ½" tubing onto the barb fitting and the other end on the barb fitting on the

NOTE: Ensure the tubing goes in a DOWNWARD direction the entire length to avoid
back-ups.
1.3.8 In the fluidics compartment there is a safety drain in the case of a catastrophic failure
to one of the pumps or 5-way valve assemblies. This drain is located under the unit and will
evacuate any pooled reagent from the interior cabinet of the AutoBlock. A tray or tubing
and container should be placed at the outlet point to contain any potential liquid coming
from this drain port.
