6-2 Maintenance & Service
6.1 Preventive Maintenance
Always keep the analyzer and its immediate surroundings as clean as possible to help keep debris out
of the system. Clean up any fluid spilled near the analyzer, and wipe up any spills on the sample rotor.
In addition, periodically performing certain preventive maintenance procedures will help keep the
HM5 in optimal operating condition to ensure peak performance and high-quality results.
Preventive maintenance can be managed in two ways on the HM5: using the Scheduled Maintenance
setting in the Admin Settings (accessible only to Admin users), or through default settings in the soft-
ware.
The analyzer displays reminders when the two primary routine cleanings need to be performed:
If Scheduling is disabled: a yellow triangle appears in the
upper-left corner of the screen when cleaning is due. Select
the triangle to see details.
If Scheduling is enabled, you can
adjust the cleaning fre-
quency within allowed limits.
Reminders appear three days,
two days, and one day before cleaning is due. You can
select Next in these messages to perform the cleaning, or
Dismiss to postpone. Cleanings can also be performed by
going to Maintenance > Cleaning and selecting the clean-
ing procedure desired from there.
On the date and time cleaning is due, the analyzer displays a cleaning due message.
Note: Once the cleaning due message appears, cleaning must be performed
before the next measurement is run. You will not be able to run samples
until cleaning is performed.
