Chapter 6: Maintaining Your Filtered PCR Enclosure
Initial Certification
The Purifier Filtered PCR Enclosure has been certified at the
factory for an average downflow velocity of 55±10 fpm along with
the HEPA Filter Leak Test. The Purifier Filtered PCR Enclosures
should be certified for the proper downflow velocity required by
your Safety Officer. It is also a conservative recommendation to
perform the HEPA Filter Leak Test again should there be any
damage caused during transport.
Re-Certification
Under normal operating conditions, the Purifier Filtered PCR
Enclosure should be recertified at least annually. The certifier
should perform the minimum following tests:
•
Downflow Velocity Test
•
HEPA Filter Leak Test
In addition, the following tests should also be performed at the
user’s discretion:
•
Measure of Line Voltage and Current
•
Smoke Test to determine proper airflow patterns
•
Lighting Intensity Test (when appropriate)
•
Noise Level Test (when appropriate)
•
Vibration Test (when appropriate)
Fluorescent Light Replacement
1. Disconnect the power.
2. Locate the small light reflector located under the control
panel.
3. Remove the light reflector by removing two Phillips screws
on the bottom of the light reflector.
4. Rotate and remove the old fluorescent lamp.
5. Reinstall the new fluorescent lamp and light reflector in
reverse order.
6. Power the unit up and try the new fluorescent lamp.
