Info

Changing the Supply Filter The BIOPROtect II JR requires one supply filter measuring 32” x 45” x 3” deep (consult test report for part numbers and specifications). This filter is arranged so as to be serviced from inside the BIOPROtect II JR’s work area. Consequently you will have to remove the cart and any equipment from inside the cabinet prior to changing the filters. To service the supply filter first swing the diffuser down allowing it to rest on the rear wall by removing the ¼-20 screws at the front edge of the diffuser panel. Next using a 3/8” driver remove the ¼- 20 hardware that secures the frame to the filter. This frame supports the filter. Prepare the new filter by putting a light coat of silicone grease on the face of the gasket. Clean the sealing flange thoroughly. Place the new filter in the center of the frame and install the frame into the cabinet using the ¼-20 hardware. Conduct a filter leak check as described in the earlier chapter. http://solid/prereleased/prereleased/STAN. PRODUCT/313/DOCS/313D000.doc Page 23 of 59
V. - TROUBLE SHOOTING Here are some suggestions based on our experience with the use and misuse of biological safety cabinets. CAUTION: Whenever the potentially contaminated areas of your cabinet must be entered, make sure that the unit is first decontaminated by use of an appropriate method by qualified personnel. When a smoke test indicates that there is air flowing from the interior of your cabinet into the surrounding room: • Make certain that the front door is closed and the front intake grilles are not blocked. This will create an 8” x 42” horizontal opening in the front of the cabinet. • If your cabinet is connected to an in-house exhaust, make sure that there is adequate exhaust suction and no back pressure. Also, be sure the dampers are open. Re-balance the exhaust system to handle an adequate quantity of air and static pressure (suction). Consult with building maintenance people. • The exhaust filter may be loaded with dirt if the unit has been in service for some time. Decontaminate, and replace the HEPA filter. • There may be high cross-drafts in the room which are causing the outflow of smoke. Check the airflow balance, following the procedure recommended in an earlier section of this chapter. Eliminate the source of the cross-draft. If there is no airflow within the work area: • Make sure that the blower switch is turned on. The indicator on the pushbutton should be illuminated. • If the lights are working, then turn the blower switch off and let the cabinet rest for ten minutes. When the time has passed, turn the blower switch on again. If the blower starts, you know there has been overheating of the blower motor. Also check the wiring connections inside of the light canopy which connects the canopy to the cabinet. Be sure the connections are pushed together. • If these solutions do not correct the problem, or if the blower failed to start after the rest period, then either the speed control, blower motor or capacitor is defective. A qualified electrician can find out if the speed control is defective by bypassing it, using the wiring diagram in the Appendix of this manual as a guide. If there is a noise problem, it may be caused by motor bearings. When there is uneven fan operation, or noise from the motor/blower assembly: • It may be necessary to decontaminate the cabinet. • Look for loose objects in the fan cage. • Check to see if the fan wheel is contacting the blower housing. • Open the light canopy and check the multi-pin connectors at each end to be sure they are securely engaged. • Another possible source of the problem is the speed control. http://solid/prereleased/prereleased/STAN.
