bar and the module seal O-ring. Secure the sample module using the three thumb nuts. Install a new O-ring on the

Be sure to clean the enzyme probes before installing them in the sample module.

8.4.10 Sipper Replacement

Caution: Touch a bare metal chassis screw before handling the sipper tube
to prevent possible damage due to an electrostatic discharge.
The Sipper can be damaged if it is not properly aligned or if its alignment is disturbed. Inspect the Sipper for straightness
and condition of the Teflon jacket separating the two stainless steel tubes. If the Teflon jacket is torn, replacement of the
Sipper is required. Follow the steps below to replace the Sipper.
From the Service screen, Sipper tab, move the sipper to Location [Station 1-P96] to allow access to the sipper.
