Instruction Manual | 13
Whenever service is conducted on the biosafety system, be sure to completely power down 
both the S3
™ 
 or S3e cell sorter through the main power switch and the biosafety system.
Service
Bio-Rad offers service support for the biosafety system. Contact Bio-Rad’s technical and service 
support toll free at 1-800-4BIORAD (or 1-800-424-6723) for service needs or replacement parts.
Bio-Rad does not conduct certification of the system onsite (this must be done by third party 
service organization), but upon installation a system test will check for proper airflow. The S3 
biosafety system will also be tested to ensure connectivity with ProSort
™
 software.
Onsite Certification
As with any biosafety enclosure or hood, the S3 biosafety system must be certified upon 
installation and annually to maintain proper safety. The system cannot be used until it is 
certified onsite. 
Certification should be performed by a qualified technician in accordance with the attached 
procedure. Contact Bio-Rad Technical Support for recommended vendors that can  
certify onsite. 
CAUTION: Risk of danger! This procedure does not address the possible exposure 
to potentially hazardous substances. Check with a biosafety professional or a health 
and safety professional before performing any service on this enclosure, including 
repair or replacement of the HEPA filter.
