ON-SITE CHECKS AND MAINTENANCE PROCEDURES
We recommend that the following checks be performed before initial use, after relocation and after each
filter change. They should also be carried out at regular intervals, usually six months or one year, as
specified by an industrial hygienist, safety officer or other qualified person. The tests described below meet
recommended minimum requirements and only experienced technicians using proper procedures and
instruments must perform them. Our representatives can tell you about other tests, which you may consider
desirable.
As reported earlier in this manual, each individual cabinet made by The Baker Company is carefully tested
before it leaves the factory. Your copy of the test report, which you will find at the back of this manual,
gives the factory test results for your own SterilGARD

III cabinet. Use it as a record of the original testing,
and as a guide to testing in the future. To gain many years of satisfactory service, please be sure that
maintenance personnel come as close as possible to duplicating these original test figures.
Your test procedures should be identical to ours so that achieving similar test results and comparison of data
will be possible. Please correspond directly with us to request detailed procedures for your particular cabinet
model. Alternate testing procedures can be found in the NSF International Standard No. 49.
The Airflow Balance
Warning!
This procedure should be performed by qualified technicians only.
The airflow balance, which is set at the factory, provides your cabinet with the proper air volume and
velocity control to minimize leakage of airborne contamination either into or out of the work area.
In order to duplicate as closely as possible the airflow characteristics described in the original factory test
report, please follow these steps:
1. Adjust the window to its designed opening height. If the window is set above this height an alarm will
sound.
2. Perform inflow velocity test per NSF 49. Specific details are on the cabinet instruction label and in the
factory test report.
NOTE: the IV bar and UV light bulb need to be removed while performing downflow readings.
3. Perform downflow velocity test per NSF 49. Specific details are on the cabinet instruction label and in
the factory test report.
4. Compare these results with those originally recorded at the factory.
Warning!
