Chapter 5 Maintenance
Introduction
Maintenance procedures ensure continued instrument performance.
u
Shut down or idle the instrument during periods of inactivity.
u
Supplement the water wash performed at the end of a run with regular maintenance washes to maintain
fluidics.
Regular instrument washes maintain instrument performance by flushing the fluidics system and
preventing salt accumulation and cross-contamination of reagents.
Preventive Maintenance
Illumina recommends that you schedule a preventive maintenance service each year. If you are not under a
service contract, contact your Territory Account Manager or Illumina Technical Support to arrange for a
billable preventive maintenance service.
Perform a Maintenance Wash
A maintenance wash consists of washing the system with a maintenance wash solution prepared with Tween
20 and ProClin 300. Perform a maintenance wash when prompted by the software every 10 days or after a
run, when a maintenance wash is an optional alternative to a water wash.
The Load Gasket screen opens with a maintenance wash every 10 days. Replace the 8-port gaskets in the
front manifold and back manifold before proceeding to the wash, even if this screen does not appear.
Prepare Maintenance Wash Solution
Prepare 5 liters of maintenance wash solutionfor use with one instrument. The solution can be stored for up to
30 days at room temperature and used up to three times during this period.
Dispose of the wash solution in accordance with the governmental safety standards for your region.
