IV - ONSITE 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 your record of the original testing, and as your guide to
testing in the future. To gain many years of satisfactory service, please be sure that your 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
Only qualified technicians should perform this procedure.
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.
2.
Perform inflow velocity test per NSF 49. Specific details are on the cabinet instruction label and in the factory
test report.
3.
Perform down flow 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 down
flow readings.
4.
Compare your results with those originally recorded at the factory.
5.
Make adjustments to the cabinet blower speed controller and balancing damper as necessary. The blower
speed controller is located inside the light canopy on the left side. The cabinet balancing damper control is
located on the top left of the cabinet. To adjust the blower speed, turn the controller screw clockwise /
counterclockwise to increase / decrease. To adjust the balancing damper, use a wrench or screwdriver to turn
the control clockwise / counterclockwise to open / close. [Reference Chart# 1: “Type A2 Air Balancing
Guidelines” on next page.]
