The Daily Shutdown Procedure consists of rinsing the Flow System. Whether or
not this procedure is followed on a daily basis depends on instrument usage and the
laboratory's procedures. It may not be necessary to perform this procedure every
day, since the instrument automatically goes into a STANDBY state (Automatic
Shutdown) if it has been idle for four hours. Before the instrument enters the
STANDBY state, the Flow Panel is automatically rinsed.
If desired, the operator may place the instrument in the STANDBY state by
pressing the [DAILY SHUTDOWN] soft key in the second level SPECIAL PROTOCOLS
menu. When this key is pressed or when Automatic Shutdown is initiated, the
following occurs:
• The Flow System is rinsed.
• The timer control, which periodically opens all of the solenoid valves to
prevent pinched tubing, is set.
The Daily Shutdown cycle takes approximately 10 minutes.
For a more thorough cleaning of the instrument prior to Daily Shutdown, perform
the following procedures:
1. In the SPECIAL PROTOCOLS menu, press [AUTO CLEAN].
2. Clean Sample Loader including racks and Tower Cover.
3. Press [DAILY SHUTDOWN].
4. Leave Power ON.
5. Empty Waste (as needed)
NOTE: The Auto-Clean cycle may be run as part of the Daily Start-Up
Procedure, depending on operator preference. The Clean Needle
process should be used if there is a problem with Closed Mode
aspiration and an obstruction in the needle is a suspected cause.
The Auto-Clean and Clean Needle procedures are described in detail in Section 9:
Service and Maintenance; Subsection: Daily Maintenance Procedures.
Procedures for cleaning the Sample Loader are described in detail in Section 13:
Sample Loader.
In addition to the daily procedures listed above, if the instrument will remain idle
for a period of time, then supplemental shutdown procedures are required
depending on the expected duration of the idle time — Short-term, Intermediate,
or Prolonged Shutdown. These categories are discussed below.
