  • Page 12 The intermediate connection of the cabinet to any external exhaust system (in-house) can be performed by using an exhaust transition, which is available for purchase from Forma Scientific Inc. This exhaust transition requires a minimum of 16-1/2" headroom from the top of the cabinet.

    4.1 CONTROL & INDICATING DEVICES (REFER TO DRAWINGS 4.0, 4.1 and 4.2 FOR PROPER IDENTIFICATION) Before operating the cabinet, it is recommended that the user(s) become familiar with the following items on the cabinet. A) BLOWER SWITCH The blower switch controls the on/off power to the internal blower. B) LIGHT SWITCH The "dual purpose"...
  • Page 15 E) STATIC PRESSURE GAUGE (IN. W.G.) The static pressure gauge, located on the control panel, measures the air pressure differential across the filters, providing an indication of filter "loading". As the filters become loaded, the resistance to air passage increases, and the reading on the static pressure gauge increases accordingly. When the reading increases by 50% (from original measurement), cabinet airflow should be checked with a thermoanemometer, by a qualified service technician.

ALL ACTIVITIES TO BE PERFORMED WITHIN THE CABINET SHOULD BE APPROVED BY A BIOLOGICAL SAFETY OFFICER OR OTHER QUALIFIED INDIVIDUAL. 3. SINCE THE HEPA FILTERS REMOVE PARTICULATES ONLY (NOT GAS), EXPLOSIVE/FLAMMABLE SUBSTANCES SHOULD NEVER BE USED IN THE CABINET, UNLESS APPROVED AND MONITORED BY A BIOLOGICAL SAFETY OFFICER OR OTHER QUALIFIED INDIVIDUAL.

  • Page 25 6.1 GENERAL RECOMMENDATIONS 1) Keep the movement 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 26 6.3 CABINET CHECK 1) Check to see that the DRAIN VALVE is closed (handle in a horizontal position), so that if a spill should occur on the work surface, it will remain in the drain system and not drain onto the laboratory floor and cause contamination.

If a "contaminated" area of the cabinet must be entered to determine and/or resolve the source of a particular problem, THE CABINET MUST FIRST BE DECONTAMINATED. CAUTION: ACTUAL SERVICING OF THE UNIT MUST BE PERFORMED BY QUALIFIED SERVICE PERSONNEL ONLY! PROBLEM 1: AIR FLOW IN THE CABINET WORK AREA AND THROUGH THE EXHAUST...
  • Page 29 PROBLEM 3: FLUORESCENT LIGHT MALFUNCTION POSSIBLE CAUSES: 1) Check lamp pins and socket ends for contact. 2) Defective lamp. PROBLEM 4: LOUD SCREECHING NOISE POSSIBLE CAUSES: 1) Indicates bad bearings in motor blower unit. 2) Blower scroll is rubbing against housing.

  • Page 31 8.1 CHECKING THE STATIC PRESSURE GAUGE "ZERO" NOTE: In order to provide an accurate reading, the indicating needle of the static pressure 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 32 8.3 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, intake velocity and supply velocity.
