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 Manual Instrument Wash
Manual instrument wash options include the Quick Wash and the Manual Post-Run Wash.
Wash Types
Description
Quick Wash
Duration: 20 minutes
A quick wash is required every 7 days that the instrument is idle or after an instrument
shutdown.
The wash flushes the system with a user-supplied wash solution of laboratory-grade
water and Tween 20.
Manual Post-Run Wash
Duration: 90 minutes
A manual post-run wash is required when the automatic post-run wash is not performed,
such as when a run is ended early and the flow cell is saved for later rehybridization.
The wash flushes the system with user-supplied 0.12% sodium hypochlorite and a wash
solution of laboratory-grade water and Tween 20.
NOTE
Always use a fresh dilution of NaOCl prepared within the last 24 hours. If you make a volume larger than 1 ml,
store the remaining dilution at 2°C to 8°C for use within the next 24 hours. Otherwise, discard the remaining
dilution of NaOCl.
A manual instrument wash requires the wash cartridge and a wash flow cell provided with the instrument.
Alternatively, you can use a used flow cell for the wash.
