This section describes maintenance procedures for the Archon, including how to
change the soil and water probes and soil transfer line.

WA R N IN G :

S H O C K H A ZA R D

Service to the Archon should only be performed by qualified
service personnel. Before any service is performed, turn the
instrument OFF and remove the main power cord. Allow
sufficient time for all heated zones to cool before
proceeding.

When cleaning any components of the Archon, e.g., exterior, robotic slide rods or
leadscrews, gripper arms or sample tray, use only an isopropanol and water
solution placed on a lint-free and oil-free cloth.
