Procedure for filter leak tests • Decontaminate the cabinet in accordance with NSF/ANSI standard-49-2002 and your health and safety officer. • Remove the front upper panel by first removing the ¼-20 hardware. Remove the damper from the front of the filter. This will expose the exhaust filter. • Find the 1/8” NPT hose barb on the top of the cabinet used for measuring the upstream concentration of challenge. • Turn on the aerosol photometer and set-up according to the manufacturer's instructions. • With the cabinet’s blower running, position the D.O.P. generator so as to introduce air generated smoke into any of the work bay openings (side wall to door openings or rear wall openings are all appropriate for introducing challenge). Measure the upstream concentration of the challenge. You must have a concentration of at lease 10 micrograms per liter. • Supply Filter: Remove the diffuser prior to scanning the filter. Holding the photometer probe no more than one inch from the filter face scan the entire surface area and perimeter (filter gasket frame area) in slightly overlapping strokes at a traverse rate of not more than ten feet per minute. • Exhaust filter: You may scan the downstream face of the exhaust filter from outside of the cabinet. • Eliminate leaks in the gasket frame area by re-tightening the filter gasket. • An unacceptable leak is defined as a reading greater than 0.01% http://solid/prereleased/prereleased/STAN.

The Airflow Balance Warning! This procedure should be performed by qualified technicians only. The airflow balance which is set at the factory provides your unit with the air volume and velocity control to minimize leakage or airborne contamination either in 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. Make certain that the front door and viewscreen are closed and secured so as to make an 8” x 42” horizontal access opening. 2. Using a DIM (Direct Intake Measurement) measure the flow rate into the front access opening. Take at least five (5) consecutive readings. Average the readings and divide by 2.3 square feet (area of the front access opening). Acceptable range of the average shall be 100-110 FPM. 3. Using a hot wire anemometer mounted on a ring stand within the work area, take readings with the anemometer probe set 6” below the diffuser. The location of these readings should be the same as shown in the factory test report. The average of these velocity readings must be in the range between 50 and 70 FPM. 4. After you have compared your figures with those originally taken at the factory, make whatever adjustments are necessary. Use the motor speed control and the exhaust damper to bring the intake and downflow average values within the specifications. 5. As the HEPA filters load up with particulates, airflow will be maintained automatically to some extent. When the air flow is diminished you will have to increase the motor speed to maintain the specified intake and downflow velocity averages. This is done via the speed controller located in the light canopy. Warning! When the light canopy is lowered, some electrical parts are exposed. Do not perform this work unless you are a trained electrician or electronic technician. !!!!Note that terminals M1 & M2 as well as L1 & L2 are high Voltage.!!!! On the speed controller, turn the potentiometer clockwise until you have the desired airflow. Use a voltmeter to check the voltage across terminals M1 & M2. This is the voltage out to the motor. If the airflow cannot be maintained, it will necessary to replace the HEPA filters. (See “Procedure for HEPA Filter Replacement” later in this section.). http://solid/prereleased/prereleased/STAN.
