Annex E35

Recommendations for installation

E.1 Recommendations for installation

E.1.1 Location

E.1.1.1 The Class II (laminar flow) biosafety cabinet should be located out of the traffic pattern and away from room air currents that could disrupt the containment provided by the work access opening air barrier.

Annex E, figure E1 shows a suggested location after all air turbulence sources have been considered.

E.1.1.2 If there is a window in the laboratory, it should remain closed at all times. Cabinets should not be located where room ventilation air inlets blow across the front opening or onto the exhaust filter.

E.1.1.3 Where space permits, a 12 in (30 cm) clearance should be provided behind and on each side of the cabinet. If not feasible, a minimum 3 in (8 cm) clearance on each side and 1.5 in (3.8 cm) clearance in back are recommended. The electrical outlet for the cabinet should be accessible for the cabinet service and electrical safety testing without moving the cabinet.

E.1.2 Recommendations for installation

E.1.2.1 Type A1 and A2 cabinets

Type A1 and A2 cabinets are designed to return air to the laboratory and do not generally require external venting. It is critical that a minimum of 3 in (8 cm) clearance be provided between the exhaust opening on top of the cabinet and the ceiling. Less than 3 in (8 cm) clearance constricts the exhaust and reduces the flow into the cabinet at the front access opening. At least 12 in (30 cm) clearance is required between the exhaust opening on top of the cabinet and the ceiling to allow the use of a thermal anemometer to measure the exhaust velocity when calculating the cabinet inflow velocity.

When it is desirable to exhaust air to the atmosphere, exhaust should be via a 100% exhaust system (i.e., a system that does not recirculate its exhaust air into other parts of the building). The recommended exhaust system connection for types A1 and A2 cabinets is an exhaust canopy connection as shown in annex E, figures E2 and E3. Every canopy design must be tested to determine the airflow rate exhausted by the canopy that will ensure performance. Whenever the cabinet is field certified, the minimum exhaust flow by the canopy should be verified by measurements using the approved instruments and techniques cited in annex A, sections A.9 and A.10. No type A cabinet should ever be hard connected to an exhaust system (see figures E4 and E5).

It is preferable that cabinets be installed using an exhaust connection that allows for scan testing of the exhaust HEPA filter in accordance with annex F, section F.5.3.1.

A properly designed and installed exhaust canopy will allow a Type A1 or A2 cabinet to maintain acceptable inflow velocity at the front access opening even when the flow through the exhaust canopy is completely stopped. The performance of the exhaust canopy should be assessed by either the manufacturer of the exhaust canopy or the user to ensure awareness of the performance characteristics of the exhaust canopy with the particular model of cabinet being exhausted.

35 The information contained in this Annex is not part of this American National Standard (ANS) and has not been processed in accordance with ANSI’s requirements for an ANS. Therefore, this Annex may contain material that has not been subjected to public review or a consensus process. In addition, it does not contain requirements necessary for conformance to the Standard.

NSF/ANSI 49 – 2002 © NSF 2002

When the exhaust canopy is used to capture hazardous nonparticulate material being exhausted from the cabinet, the exhaust and associated alarm system should meet the same criteria as indicated for the Types B1 and B2 cabinets.

When Type A1 and A2 cabinets are found to be directly attached to the exhaust system and vented to the outside without the use of an exhaust canopy, it is recommended that the exhaust connection be modified to an exhaust canopy.

E.1.2.3 Roof exhaust systems

Roof exhaust systems serving biosafety cabinets should have a stack that extends straight upward at least 10 ft (3 m) above the roof surface to avoid re-entrainment by the building, and should be increased in elevation when necessary to avoid the influence of surrounding structures. Raincaps or any other structure that deflects the straight upward flow of the discharged air should be avoided. No precipitation can enter the stack when air is being exhausted at normal stack velocities. To take care of precipitation during periods when system is shut off, a 1 in (2.5 cm) hole can be drilled in the lowest point of the fan casing and the water allowed to drain onto the roof. It is recommended that roof exhaust fans be energized by direct-connected electric motors to avoid failures caused by slipping and breaking of belts.

Another advantage of direct-connected fans is the ability to use the motor non-function to activate an alarm in the laboratory, whereas when a malfunctioning belted fan is employed, the motor can be operating when the fan is idle. A diagram illustrating a recommended roof exhaust facility is shown in annex E, figure E7.

E.1.3 Electrical

Variations in line voltage may affect the cabinet airflows. A voltage regulator should be installed in order to reduce the potential of variations in airflows.

Installing the Sidewall Sensor The Sidewall sensor has been designed for single and dual wall cabinet installations. In a dual wall installation, the airflow path is made using the supplied 24” (.6m) of supplied PVC tubing and plastic end cap. In a single wall installation, no tubing or end cap is required.

In a single wall cabinet, the side wall sensor is placed on the front or side of the unit, above the sash operating height by at least 4” (100mm). If cutting through the side of the cabinet, the hole should be roughly halfway to the back of the cabinet.

In a dual wall cabinet, the sensor assembly is generally placed on the front of the cabinet, and connected to the through hole via the PVC tubing.

The Sidewall and optional Inline Sensor assemblies are used when it is not desirable to place a Probe style velocity sensor into the overhead ducting. The Sidewall/Inline sensors measure the negative pressure of the cabinet, by installing them in an airflow path created by cutting a through-hole in the side of the cabinet, which, due to negative pressure, pulls in laboratory air. This measured airflow self-correlates to face velocity.

1. Power up Apply power to the Rooster Airflow Alarm with the supplied AC voltage adapter (24vDC) voltage connection or complete a hardwired installation (TC62300 only).

The Cambridge Accusense® logo will light up sequenced LEDs and the audio alarm will announce its startup sound.

If the Rooster has been previously calibrated, startup sequence will read the airflow threshold from nonvolatile memory. If all systems are go, the green LED will light-up and flash once every two seconds.

If your Rooster has not been previously calibrated, the red LED will turn on for three seconds and then off

2. Calibration Process A (see alternative Process B and DIP switch settings on back) Once the cabinet airflow is running at operational air velocities you can calibrate the Rooster.

To establish new threshold settings:

• Locate the small hole on the faceplate below the sound holes and above the Accusence™ logo.

• While powered up, using a paperclip, depress internal switch for only 3 seconds.

Audio alarm chirps once.

• During calibration cycle (about 24 seconds) the red LED light will flash once per second.

• System finishes calibration when the red LED flashes three times fast and the audio alarm chirps once.

• The LED light turns green during airflow monitoring and will flash once every 2 seconds.

Calibration settings remain in memory even when the Rooster is turned off.

3. Turbulence Fault If during the calibration cycle the reset button is yellow and flashes quickly, the airflow probe is sensing a turbulent airflow condition and cannot establish a velocity threshold.

Install probe in a more reliable location or make adjustments to the airflow path through the duct system. Make sure the L-shaped sensor probe & head point toward the direction of airflow.

The reset button will continue to flash until a new calibration setup is done. See Calibration Process.

4. Run State During airflow monitoring, with a calibration threshold setting established, the alarm relay is energized and a green LED will flash every 2 seconds. If the airflow velocity drops below the threshold level for more than 5 seconds, the audio and visual alarms will be activated.

5. Alarm State When a low-airflow condition has been detected the alarm relay is de-energized, flashing the red light quickly and triggering the audio alarm with a two-part hi-low tone. By pushing the reset button you can silence the audio alert, the red LED will continue to flash.

To return to operational monitoring mode, push and hold the reset button for 5 seconds.

The green LED will light and return to Run State, but will trigger the alarm if fault still exists.

To reset the Rooster to new airflow velocities, establish the necessary airflow conditions in your cabinet and duct system and initiate a new calibration process (2).

6. Error State If the Rooster reaches a fault condition the reset button will light up yellow and the an audible warming sound will be heard. In this condition a forced power reset is necessary. Disconnect the power source, wait ten seconds, and reinstate power. The Rooster will go through its power-up system test and a green LED will light up based on previously established calibration settings.

7. Night Setback (TC62305 only) If your Rooster is configured with the Night Setback* enabled, when the Building Management System signals the Rooster, the center reset button will flash yellow but will not make a warning tone. If there is an equipment fault the LED light will flash red.
