BioProfile FLEX2 ESM Instructions for Use Manual
5.1.5 ESM Long-Term Shutdown
The ESM Long-Term Shutdown function is an important maintenance procedure that an
operator should be familiar with performing. If the ESM will be powered off for a period
greater than 72 hours, the system should be purged of all residual uid in the internal
tubing or ow paths. Failure to prepare the system for long periods of shutdown will
result in reagent crystallization and internal tubing blockages, which may require service
to correct.
WARNING: Leaving the ESM in a powered-down state or without installed valid uid
cartridge for more than 3 days may result in analyzer damage. Any shutdown
period lasting longer than 3 days should be preceded by purging the ow path
in accordance with this procedure.
Long-Term Shutdown Cartridge
FLEX2 analyzers operating with software version 4.0 or newer can utilize the ESM
Shutdown Cartridge (PN 60612) to properly shutdown the system for extended periods
of inactivity.
To perform a Long-Term Shutdown:
1. Remove the active ESM Reagent Cartridge from the pack bay, while keeping all
other ow components installed.
2. Install the ESM Shutdown Cartridge into the ESM pack bay. Ensure the tments
on the rear of the pack engage with the needle shrouds in the back of the pack
bay.
3. Once the pack is installed, the ESM shutdown sequence will automatically begin.
Shutdown solution will be pumped from the cartridge into the ESM owpath.
4. Once the sequence completes, power down the ESM using the power switch on
the rear of the analyzer.
NOTE: The Long-Term Shutdown procedure for the ESM can be run at the same time
as the Long-Term Shutdown procedure for the FLEX2, but the ESM Shutdown
Procedure must be started rst.
Long-Term Shutdown Flush Fixture
If the Long-Term Shutdown Cartridge function is not available, the 6-port Flush Fixture
can always be utilized to perform the ESM Long-Term Shutdown sequence.
Purging the system requires the use of the following:
• PN 58355 Flush Fixture 6 Port
• Beaker with at least 250 mL of DI H20
• Empty Beaker (capable of holding 250 mL of water waste)
