Chapter 1 – Re-Certification by Service Personnel
Esco products generally provide years of trouble-free operation. However, like any other equipment, they
require maintenance and service. Maintenance and service should be carried out by trained personnel. Esco
offers training courses to equip service providers with the latest skills, information and tools to successfully
maintain and service Esco products. For more information on the nearest training course, please contact Esco.
Service providers should familiarize themselves with the basic operating principles of products before working
on them. Suitable references include information in the User Section of this Manual or brochures which may be
downloaded from the Esco web site.
Polymerase Chain Reaction Cabinets generally require:

Re-certification, when:
o
The cabinet is relocated
o
Decline of cabinet performance is suspected
o
After filter or blower replacement
o
At least once a year
During recertification:
o
Cabinet airflow velocities and flow patterns are verified against the manufacturer’s
specifications and relevant international standards
o
Filters are scan-tested to ensure they do not leak
o
Operator comfort tests may be performed
o
If airflow velocities are found to be off the setpoint, adjustments are made as part of the
certification process before final values are recorded.

Filter replacement, when:
o
The filters are clogged and the fan(s) is/are already adjusted to maximum setting
o
Filter leaks which cannot be repaired are found during scan-testing

Fan replacement (typically rare) if failure occurs.

Routine maintenance also includes:
o
Fluorescent lamp(s) replacement - typically once every 2 years.
o
UV lamp replacement - typically once every 1 year.
