Cabinet Filter Life Gauge Operation and Resetting for Local Conditions

The filter life gauge calculates the remaining filter life by measuring and comparing the current motor speed to the initial speed noted at the factory during assembly, and the calculated maximum motor speed, using the formula:

100-(100x (current speed-original speed) ) = % filter life left max. speed-original speed

anything

 Blocking the grille.  Raising the air temperature.  Lowering the barometric pressure.

will increase the motor’s speed, causing the Filter Life Gauge to decrease. Electronic dampening of the gauge will limit the change in readings to approximately 1%/minute.

Cabinet Biosafety Cabinets being installed at altitudes or operating at temperatures significantly different from those at the time of manufacture (900 +/- 500 ft above sea level, 75o +/- 5o F) Failure to do so will result in the users noticing a steady drop in Percent (%) Filter Life remaining as the unit operates. Below are the instructions on how to correct the Filter Life Gauge for local conditions.

that changes the motor’s current speed, like:

must

have their filter life gauge recalibrated for local conditions.

1. Ensure to correct all measurement equipment for local conditions

(temperature, absolute pressure). Anemometers may not have this ability and might have to be done manually; whereas, a ShortRidgeTM instrument has a setting to correct for local conditions.

2. As the elevation or the ambient temperature rises, the motor power

factor will have to be reduced to compensate. For an initial certification, the motor speed should be reduced until it equals the Cabinet’s “Initial Motor Speed” as reported on the unit’s test sheet, plus approximately 10-15 RPM per each additional 1000 feet of elevation.

3. The Cabinet MUST be recertified using instruments corrected for local

conditions.

4. When the unit is recertified, and operating properly, the certifier MUST

RESET THE FILTER LIFE GAUGE, INDICATING A NEW FILTER HAS BEEN INSTALLED.

5. Only by performing Step #4 AFTER THE UNIT IS READJUSTED AND

RECERTIFIED FOR ITS LOCAL CONDITION, will the filter life gauge register 100% (+/- 2%) during operation. As the Filters then load, the filter life gauge will then begin to drop as appropriate.

Theory of Operation

This section offers a brief overview of the theory of operation of the Cabinet.

Airflow Patterns

Figure 1-8

All cabinets meet the airflow requirements of ANSI/NSF Standard 49:2014. Approximately 55-60% of the air in the cabinet is filtered and recirculated, while 40-45% is filtered and exhausted. ALL Cabinets feature intrinsically safe designs, jacketing contaminated positive pressure areas with negative pressure zones.

ECM Motor

The modern Class II Biosafety Cabinet was developed in the early 1960’s as a result of the increased availability of High Efficiency Particulate Air (HEPA) filter

technology. The motor of choice at the time to drive the cabinet’s blower was

the Permanent Split Capacitor (PSC) type. At the time, the PSC motor offered manufacturers an inexpensive power source whose speed could be electronically controlled to allow for airflow adjustment as the HEPA filter(s) loaded.

The PSC motor is known as an induction type, for stationary windings (stator) surround a rotating part (rotor) composed of iron or steel. As current passes through the stator windings, it induces a magnetic field in the rotor, causing it to rotate towards the shifting field in the stator. Because a magnetic field must be induced in the rotor, the PSC motor is asynchronous, with the rotor constantly lagging behind the fields being created in the stator. As a result of this asynchronous operation, the PSC motor is inefficient, and generates high amounts of waste heat. Attempting to control the blower speed by reducing its voltage only increases the inefficiency of the PSC motor.

Product Service 1-800-522-7658

Page 31

DC motors are more efficient than their AC counterparts. In a typical DC motor, the stator in an AC motor is replaced with permanent magnets. The rotor then has a series of windings around it. When current is applied to the motor, a magnetic field is created in some of the windings of the rotor, causing it to rotate toward the magnetic field created by the permanent magnets. Brushes in contact with a commutator allow the current, and thus the magnetic field in the rotor to progressively shift from winding to winding, forcing the rotor to keep rotating.

The greatest drawback of brushed DC motors is the brushes-they wear themselves and the commutator down, eventually causing motor failure.

With the development of greater microprocessor power in the 1970s and 80s, the stage was set for an even more efficient type of DC motor – the Electronically Commutated Motor (ECM).

Figure 1-9

In the ECM, the magnets and windings switch position – the permanent magnet is on the rotor, and the series of windings are placed around the rotor. The microprocessor precisely controls the creation of magnetic fields in the stator, so that the rotor is always synchronous with the magnetic fields being created in the stator. As a result, the ECM will always run more efficiently and cooler than a comparable PSC motor. Because of the simple, robust construction of the ECM, it offers far greater reliability and operational service life than the PSC motor.

Controlling the motor’s operation with a microprocessor adds numerous

advantages. Motor speed can be efficiently controlled across a speed range that would damage or destroy a PSC motor. Given enough microprocessor memory and power, the manufacturer can program in any number of user-selected programs controlling motor speed, power and even direction of rotation. The ultimate expression of the power of the ECM was the development of the constant volume algorithm, by General Electric, and used in the Cabinet BSC. By testing a prototype model to a variety of airflows and filter pressures, the

motor/blower can be “characterized” for that size cabinet. This characterization

allows for the creation of a model-specific motor-blower curve. By programming the curve values into the motor during assembly, the motor will deliver the correct volume of air as the HEPA filters load.

Table 2-1

The biosafety cabinet models have the following electrical requirements:

Note: A dedicated outlet with an appropriate circuit breaker should be located as close as possible to the right rear side of the cabinet, at a height even with, or higher than, the top of the bench or stand. Consult your local electrical codes for properly rated circuit breakers. For safe operation the dedicated outlet must provide the protective earthing ground connection to the cabinet.

Note: On 100 and 115 VAC models, both electrical outlets are protected by a

ground fault interrupter circuit (GFIC). Labconco does not recommend plugging the biosafety cabinet into a GFIC outlet.

Electrical outlets in the cabinet are restricted to 5 amps maximum

current.

Prises électriques dans l'armoire sont limitées à 5 courant maximum ampères.

The biosafety cabinet models have the following electrical requirements:

Do not use any detachable power cord that is not adequately rated for

the unit.

Ne pas utliser un fil électrique amovible qui n’est pas du tension nominale de l’appareil.

Product Service 1-800-522-7658

Page 39

Service Line Requirements

All utility service lines should be ¼ inch O.D., brass, copper, or stainless steel, and equipped with an easily accessible shut-off valve. If the service line pressure exceeds 40 PSI (276 kPa), it must be equipped with a pressure regulator to reduce the line pressure.

Note: The use of flammable gases or solvents should be avoided in the biosafety cabinet. Open flame in the cabinet will disrupt the laminar airflow in the cabinet and may damage the HEPA filters. Flammable gases or solvents may reach explosive concentrations in the cabinet or ductwork. If you feel that the procedure requires the use of an open flame or flammable materials, contact the institution’s safety office.

The use of air or gases under high pressure should be avoided as they may seriously disrupt the airflow patterns in the cabinet.

Connecting the Biosafety Cabinet to Utility

Figure 3-2

Service Lines

Note: Some models have a solenoid valve connected to the service valve on the right side, rear position. The solenoid prevents gas from flowing to the service valve when the unit blower is off. It is the only service valve position that can be fitted with a solenoid valve. Connect the gas service to the solenoid valve.

The service lines (if any) should be connected to the tube fitting(s) on the outside of the liner wall as shown in Figure 3-2 To install the tubing, follow these steps:

1. Ensure that the tubing is ¼ inch O.D., soft metal, and that the end has been

completely deburred.

2. Route the tubing from the rear of the cabinet, ensuring that it will line up with the

slot in the back of the side panel. The slot is located from 8 ¾ to 11 ¼ inches (222 to 288 mm) from the bottom of the cabinet.

Note: Make sure that the tube routing will not contact any electrical wires. DO NOT loop service line tubing within the side panels of the cabinet.

3. Make sure that the nut on the tube fitting is loose, but do not remove it. Look inside

the fitting to make sure the tube ferrule is there.

4. Push the tube into the fitting until it is properly seated. The tube will go

approximately ¾ inch (19 mm) into the fitting.

5. Tighten the tube fitting nut hand tight and then, using a 7/16-inch wrench, tighten it

at least ¾ turn more.

6. Close the service valve in the biosafety cabinet and then slowly open the shutoff

valve on the service valve. Test all fittings for leakage. Tighten the tube nut slightly if needed.

Optional VentusTM Canopy Exhaust Connection

Certain applications such as working with odorous products or volatile toxic materials will require the connection of the biosafety cabinet to an exhaust system.

Note: The canopy connection, also referred to as a thimble or air gap connection, allows single or multiple biohazard cabinets to be connected to an exhaust system. During operation, the exhaust system draws all of the cabinet’s exhaust air, plus a volume of room air (through the Inlet Relief Valve in the canopy) into the exhaust duct.

Canopy connections function as a “shock absorber” allowing the system to function

properly during changes in room air pressure.

For information on selecting a canopy connection, go to

Note: If the research involves the use of toxic compounds or volatile materials, contact

the facility’s safety officer or Labconco to ensure that the biosafety cabinet and its

exhaust system are compatible with the materials you will be working with.

Optional Vacu-PassTM Cord & Cable Portal

Figure 3-3

Use

Note: There must be enough clearance to pass the cord or cable between the Cabinet’s exterior dress panel and any obstruction.

Note: Some Vacu-Pass components and the cord or cable passing through it may become contaminated during use of the cabinet. Ensure all potentially contaminated components are surface decontaminated before handling or removal from the cabinet.

1. Remove the grommet from the liner side wall. Remove the solid sealing plug from

the body of the portal by either pressing it through from the outside, or by carefully inserting a spatula or similar device between the sealing plug and the body of the portal, and prying the plug out.

2. Pass the cord or cable through the body of the portal, and then through one of the

plugs that has been cut for cord or cable use, then through the grommet, as shown in Figure 3-3.

Note: select a plug with a hole that is slightly smaller than the cord or cable, to create a proper seal. This will also help minimize movement of the cord or cable if it is accidentally pulled during use.

3. Position the cord or cable as it will be used in the cabinet, and then push the plug

back into the body of the portal until it seats in the portal. Reinstall the grommet.

Drain Valve Installation

Figure 3-4

In order to prevent damage during shipping, the drain valve assembly has not been installed. If desired, the valve should be installed after the cabinet is in its final location.

To install the valve assembly, follow these steps:

1. Lift the work surfaces out of the biosafety cabinet by lifting on the knobs at the front

of the work surface.

2. Using a putty knife, remove and discard the stainless steel cover that is sealed over

the drain mounting holes. Scrape out remaining sealant that is around the holes.

3. Apply a light coating of silicone sealant (user supplied) to the mounting surface of

the drain assembly. Attach the drain assembly under the bottom of the cabinet as shown in Figure 3-4. Wipe off any excess sealant from the cabinet bottom. Ensure that the center drain hole is unobstructed.

4. Make sure the drain valve is in the closed position.

5. Reinstall the work surfaces.

6. Allow the silicone sealant to cure for at least eight hours before exposing it to liquid.

NOTE: The drain valve assembly attaches to the underside of the cabinet bottom.

Apply a light coat of silicone sealant to this surface of the connector, aligning the three holes in the connector with the three holes in the biosafety cabinet liner.

Figure 4-3

The Information Center is an LCD display located on the right side wall at eye level. When the blower is started, if the Cabinet is configured to be connected to an exhaust system, Figure 4-2 will appear for 60 seconds while the unit initiates operation.

After 60 seconds, the default display screen will appear. The display provides a clock,

the life remaining for both filters, the cabinet’s current status, inflow velocities (if

equipped with the optional airflow sensor), as shown in Figure 4-3. In the event of an alarm, the Information Center will immediately display a context sensitive display indicating the cause of the alarm, and possible solutions, as shown in Figures 4-4a-f.

The display will enter sleep mode, turning itself off, one minute after the blower is turned off or the sash is closed.

Airflow Alerts

The airflow patterns in the cabinet have changed, resulting in a sudden change in either motor speed. This is most likely due to a blockage of the grille or the exhaust filter outlet. It may also be caused by removal of the work surface(s) while the cabinet is in operation.

Exhaust Fan Alarm

There has been a failure of the exhaust fan, or its communication to the cabinet’s control board. DO NOT USE THE CABINET UNTIL THE PROBLEM HAS BEEN CORRECTED.

Exhaust System Alarm

When equipped with the Ventus Canopy, and the exhaust system fails to move a sufficient volume of air, this display screen is shown, and an audible alarm heard. If this alarm is displayed, the cabinet blowers will need to be turned off, and then back on again to reset the alarm. Frequent Exhaust System Alarms indicate unstable or insufficient exhaust flow, and must be corrected.

System Error

The motors and display circuit board are not communicating properly. DO NOT USE THE CABINET UNTIL THE PROBLEM HAS BEEN CORRECTED.

Method

Note: The dress panel MUST be installed on the cabinet to obtain an accurate inflow value.

The average inflow velocity for Cabinet models is 105 ±5 FPM. It should be determined by converting the inflow volume to the average inflow velocity. The inflow volume is measured directly by sealing a direct inflow measuring flow meter to the face of the unit. When corrected for local conditions, dividing the inflow volume by the opening area will yield the average inflow velocity.

Table 5-4

Inflow Test Specifications

Acceptance

Average inflow shall be meet the specified value.

Product Service 1-800-522-7658

Page 75

Inflow Velocity Calculation - Secondary Method

If the primary method cannot be performed, the secondary inflow calculation method should be used. The secondary method uses a hot wire thermal anemometer. In this method, the sash is lowered, and a series of velocity readings are taken at the front of the unit.

NOTE: You must use a Labconco Certifier Kit, Labconco P/N 3858403 to perform this test properly. Qualified certifiers can obtain this kit by contacting Labconco Customer Service Department at 800-821-5525.

For each model Purifier, the sash should be closed until the appropriate marked template (4+, 5+ or 6+) contacts the sash stop and the bottom edge of the sash, as shown below in Figure 5-10.

The thermal anemometer probe should be positioned such that the distance from the

bottom of the probe holder to the center of the sensor element equals “Sensor Distance”

as shown in Table 5-5. Use the marks on the 6-foot templates, or a scale as shown in Figure 5-11 & 5-12 below.

Sash

Operation

The Cabinet sash uses a deadweight-counterbalanced system. The system consists of two separate weights on either side of the liner. Both weights are synchronized by a locked axle-pulley system. Both pulleys are fixed to the axle so that both weights must move together, preventing the sash from racking.

Adjustment

There are no adjustments for the width of the sash track. There should be approximately 1/8-inch lateral play of the sash in its track. If there is no lateral play, examine one or both of the corner posts to ensure that they are not bent inward. If the sash becomes racked, or is closing unevenly, it can be aligned as follows:

1. Close the sash completely, until the lower edge of the sash is contacting

the sash stop. If the other end of the sash is not resting on its sash stop,

CAREFULLY lift the counterweight on the “high” side of the sash. This will

allow the high side of the sash to lower to the sash stop, leveling the sash. See Figure 6-5.

Preparing the Cabinet for Gaseous Sterilization

Note: This section only reviews the steps required for preparing the Cabinet for Gas Sterilization. Thoroughly understand the sterilization procedures and protocols supplied by the manufacturer of the sterilizing system before attempting this operation.

1. Unplug the Cabinet from electrical power.

2. Thoroughly surface decontaminate the working area of the cabinet.

In order to get a complete seal on the front of the cabinet, do the following:

1. Remove the work surface after it has been surface decontaminated.

2. Remove the towel catch, and locate the Sampling/Decontamination Tube, as

shown in Figure 6-32.

3. Remove the front grille.

4. Place the work surface and the grille into the work area for decontamination.

5. Remove the front dress panel.

6. Remove the sash stop bracket, located near the top of the blower plenum cover.

7. Lift the sash up until the bottom edge of the sash clears the bottom edge of the

Supply HEPA Filter shelf.

8. Using flexible plastic sheet 5-8 mil thick and duct tape seal the perimeter of the

front opening. If you wish to connect the sterilizer’s discharge tube to the Cabinet’s Sampling/Decontamination Tube, do this now, and properly seal the discharge tube to the plastic sheet.

9. Open the exhaust filter cover.

Note: DO NOT attempt to remove the brackets that secure the exhaust filter cover; they are needed to maintain rigidity on the top of the chassis.

10. Using flexible plastic sheet and duct tape seal the Exhaust filter opening.

11. The Cabinet is now prepared for gaseous decontamination.
