Page 16: Location
5.1 LOCATION Locate the cabinet on a firm level surface in an area of minimum ambient temperature fluctuation. The cabinet should be placed in a somewhat remote area of the laboratory, away from disruptive air currents caused by excessive personnel traffic, air-conditioning or heating ductwork, and/or laboratory windows and doors. -
Page 17: Exhaust Requirements
Model 1132: 380-425 CFM The system must have adequate static pressure for proper and safe operation of the cabinet. STATIC PRESSURE SHOULD BE: Model 1122: .25" to .50" W.G. Model 1126: .25" to .50" W.G. Model 1132: .25" to .50" W.G. -
Page 18: Exhaust System Connections
5.7 EXHAUST SYSTEM CONNECTIONS Class II, Type A biological safety cabinets, can be attached to an exhaust system in one of two ways: A) A canopy connection. B) A direct, gas-tight connection. A) CANOPY CONNECTION: The May 1983 revision of NSF Standard 49 recommends the canopy connection as the hookup of choice. - Page 19 SECTION 6 - CERTIFICATION TESTING PROCEDURES Table of Contents 6.1 Certification of the Cabinet 6.2 Plenum Leak Test 6.3 HEPA Filter Leak Test 6.4 Noise Level Test 6.5 Light Intensity Test 6.6 Vibration Test 6.7 Downflow Velocity Profile Test 6.8 Face Velocity Air Flow Test 6.9 Smoke Test 6.10 UV Light Intensity Test (Optional Equipment)

Page 29: General Recommendations
8.1 GENERAL RECOMMENDATIONS 1) Keep the activity in the room to a minimum when the cabinet is in use. 2) Keep all laboratory doors closed to prevent drafts that will disturb critical air flow characteristics. 3) Pre-plan cabinet use, and place everything required for the complete procedure in the cabinet so that nothing passes through the air barrier (in or out) during the procedure. -
Page 30: Start-Up Procedure
8.4 START-UP PROCEDURE 1) Turn ON the lights. 2) Check the intake and exhaust grills to ensure they are not blocked. 3) Turn on the blower to purge the work area of contaminated air. 4) Wash your hands and lower arms with germicidal detergent. 5) Disinfect the entire work area with 70% alcohol. -

Page 32: Checking The Magnehelic Gauge "Zero
9.1 CHECKING THE MAGNEHELIC GAUGE "ZERO" NOTE: In order to provide an accurate reading, the indicating needle of the magnehelic gauge should be precisely at zero when the cabinet is completely shut off. If the cabinet is connected to a central exhaust system, the exhaust system must also be shut off. -

Page 35: Replacing The Supply Hepa Filter
10.2 REPLACING THE SUPPLY HEPA FILTER NOTE: Access to the supply HEPA filter is through the front panel on the filter box at the top of the cabinet. 1) DISCONNECT UNIT FROM POWER SOURCE! 2) Remove the aluminum frame that supports the viewing window. 3) Remove the cap nuts and washers that secure the supply filter access panel in place, and remove panel. -
Page 36: Adjusting The Damper
10.3 ADJUSTING THE DAMPER Since the HEPA filter resistance may vary considerably from filter to filter (even filters of the same size), a damper has been installed in the cabinet exhaust system for maintaining proper airflow balance. The purpose of the damper is to regulate the amount of exhaust air to maintain the proper intake and exhaust velocities. -
Page 37: Replacing The Blower Speed Control
10.5 REPLACING THE BLOWER SPEED CONTROL NOTE: DISCONNECT THE UNIT FROM THE POWER SUPPLY BEFORE INITIATING THE REPLACEMENT PROCEDURE! 1) Remove the two screws that secure the control panel. 2) Pull out the control panel, and locate the blower speed control at the bottom of the control panel. 3) Remove the nut from the blower speed adjustment control. - Page 38 MODEL 1122 - PARTS QUANTITY STOCK # DESCRIPTION 105015 Glass, Clear Tempered Safety 156060 Motor, 1/3 HP Motor, 115V 285812 Plug 15A, 120V Hospital Grade 225250 Ballast 141026 Lamp, Fluorescent (F30T12/CW/HO) 104008 Gauge, Magnehelic 760062 Filter, Exhaust HEPA 12x24x11-1/2 760056...
