Chapter 2: Prerequisites

Support, Vibration and Movement Requirements

At a minimum, the supporting structure usually consists of a base cabinet or base stand and chemically-resistant work surface.

Location and Air Current Requirements

Purifier Vertical Clean Benches have been designed to provide particulate-free clean air meeting Class 5 conditions by negating typical cross drafts and turbulence within the opening. However, as a precautionary safety measure and a higher level of quality management, it is recommended that the clean bench be placed in an area away from:

• High traffic areas where walking might cause an air

disturbance or be a nuisance.

• Overhead or wall HVAC diffusers, fans, radiators or other lab

equipment producing air currents.

• Doorways or windows that may be opened.

Airflow Specifications

Purifier Vertical Clean Benches use an integral motorized impeller to draw room air from the top and through the enclosure. This room air is then pushed down through the HEPA filter. The enclosure is factory set to deliver 40-55 fpm downflow velocity measured 6" below the upper diffuser. The Class 5 HEPA-filtered air flows across the work area and exits out the front of the enclosure.

Data for the outflow exhaust volume, downflow velocities and outflow face velocities are listed for each Vertical Clean Bench model below.

Product Service 1-800-522-7658

Chapter 3: Getting Started

Setting the Downflow Velocity with the Speed Control Adjustment

Adjustment of the speed control gives the correct downflow velocity and is located behind the front panel. The downflow velocity should be from 30-65 fpm for Class 100 (ISO class 5) conditions. ISO Class 5 clean air conditions are maximized at a setting within this range. The Vertical Clean Bench is factory set at 40-55 fpm downflow velocity. (Consult your Safety Officer for airflow recommendations for your application). Working at the downflow velocity appropriate for the application will give the quietest operation. Downflow velocity measurements are made using an anemometer. An electric anemometer can be obtained from your laboratory supply dealer. Downflow velocity measurements should be taken 6" below the interior upper diffuser. Using a small Phillips screwdriver, adjust the speed control to give the required downflow velocity. See Figures 6-1 and 6-2 in Chapter 6 to locate the speed control. The downflow velocity is increased by turning the speed control counterclockwise and clockwise to decrease downflow velocity.

Validating the Vertical Clean Bench

To determine the actual downflow velocity, airflow velocity readings are taken. This should be done 6" down from the top of the interior upper diffuser. The “average downflow velocity” is achieved by averaging the readings in the downflow test grid for each model:

The downflow test grid consists of 9 test points, 3 points in 3 rows. The back row of the grid is 6" from the rear of the work area. The middle and front rows are 6.57" apart from the back to the front. The first and last column of the downflow grid are spaced 6" in from each sidewall with a center column spaced 5.32" away from the first and last column.

The downflow test grid consists of 12 test points, 4 points in 3 rows. The back row of the 6" from the rear of the work area. The middle and front rows are 6.57" apart from the back to the front. The first and last column of the downflow grid are spaced 6" in from each sidewall with two columns spaced 7.54" away from the first and last column.

Product Service 1-800-522-7658

Chapter 3: Getting Started

The downflow test grid consists of 15 test points, 5 points in 3 rows. The back row of the grid is 6" from the rear of the work area. The middle and front rows are 6.57" apart from the back to the front. The first and last column of the downflow grid are spaced 6" in from each sidewall with three columns spaced 8.66" away from the first and last column.

Refer to the exhaust specifications table in Chapter 2 for proper airflow volumes and downflow velocities for your particular model. A certified technician should complete validation.

The Purifier Vertical Clean Benches have been tested at Labconco before shipment and provide ISO Class 5 clean air conditions inside the enclosure. Labconco also performed extensive performance testing to validate the clean benches for product protection under ISO Class 5 conditions. For copies of these validation reports, contact Labconco Customer Service.

Sealing the Vertical Clean Bench to the Work Surface

When the Vertical Clean Bench has been set in place and wired, it may be sealed at the work surface to prevent materials from collecting under the walls. A bead of silicone sealant is recommended to seal the Vertical Clean Bench to the work surface.

Chapter 4: Performance Features and Safety Precautions

15. The surface of the HEPA filter is fragile and should not be

touched. Care must be taken to avoid puncturing the HEPA filter during maintenance. If you suspect that a HEPA filter has been damaged DO NOT use the Clean Bench; contact a local certification agency or Labconco.

16. The HEPA filter in the enclosure will gradually accumulate

airborne particulate matter from the room. The rate of accumulation will depend upon the cleanliness of the room air, and the amount of time the Clean Bench is operating. With normal usage, the HEPA filters will last two to five years before requiring replacement.

17. Avoid direct exposure to ultraviolet (UV) radiation;

NEVER work in the enclosure when the UV light is on.

18. Ensure that the Clean Bench is connected to an electrical

service in accordance with local and national electrical codes. Failure to do so may create a fire or electrical hazard. Do not remove or service any electrical components without first disconnecting the filtered enclosure from electrical service.

19. Increase the downflow velocity by adjusting the speed

control of the motorized impeller or change the HEPA filter when the downflow velocity falls below acceptable limits established by your Safety Officer.

20. Ensure only trained operators use the Clean Bench. New

users should review the User’s Manual and become familiar with the operation of the Clean Bench.

21. Proper operation of the Clean Bench depends largely upon

the enclosure location and the operator’s work habits. The enclosure should be located away from traffic patterns, doors, fans, ventilation registers, fume hoods, and any other air-handling device that could disrupt its airflow patterns.

Consult Chapter 2: Prerequisites and Chapter 3: Getting Started sections of this manual for further details.

Routine Daily Work Procedures

Planning

• Arrange for minimal disruptions, such as room traffic or

entry into the room while the Clean Bench is in use.

Start-up

Product Service 1-800-522-7658

• Turn on blower and light. Turn off the UV light, if

equipped.

• Only raise the sash for loading and cleaning.

• Allow the Clean Bench blower to operate unobstructed for

1 minute.

Chapter 5: Appropriate Applications For Your Vertical Clean Bench

• Wear a long sleeved lab coat, rubber gloves and protective

eyewear. Wear a protective mask if appropriate. Consult your Safety Officer for additional personal protective equipment recommendations.

• Wipe down interior surfaces with a mild household

detergent or disinfectant. DO NOT use abrasive cleaners, bleach or solvents.

Loading Materials and Equipment

• Load only the materials required for the procedure. Do not

overload the Clean Bench.

• Do not obstruct the upper air diffuser screen.

• Large objects should not be placed close together.

• After loading, wait one minute to purge airborne

contaminants from the work area.

Work Techniques

• Keep all materials inside the lower air foil, and perform all

operations as far to the rear of the work area as possible.

• Segregate all clean and contaminated materials in the work

area.

Final Purging

• Upon completion of work, the Clean Bench should be

allowed to operate for two to three minutes undisturbed, to purge airborne contaminants from the work area before shutting down the blower.

• If equipped, turn on the UV light to decontaminate the

work area as determined by your Safety Officer.

Unloading Materials and Equipment

• All open trays, weigh vessels or containers should be

covered before being removed from the Clean Bench.

Suitable Applications

Suitable applications for the Purifier Vertical Clean Benches are based on guidelines established by the Institute for Environmental Sciences. Particulates are filtered by the HEPA filter before air is returned to the room. Biohazardous materials or other hazardous solids cannot be used with the Purifier Vertical Clean Bench, as air is directed over the work surface and out of the enclosure. The

Purifier Vertical Clean Bench only provides product protection

and offers no personnel protection whatsoever.

Product Service 1-800-522-7658

Chapter 5: Appropriate Applications For Your Vertical Clean Bench

Listed below are suitable applications for HEPA filters.

HEPA Filter Applications, Suitability and Guidelines

• Procedures traditionally performed on an open bench where a

clean Class 5 air environment is now required.

• The HEPA filtered enclosure provides product protection from

particulate matter. Because air from the Clean Bench enters from the room during operation, this enclosure should only be used for operations requiring sample protection from environmental contamination.

• HEPA filters are only effective for entrapment of particulate

matter. The surface of the HEPA filter is fragile and should not be touched. Care must be taken to avoid puncturing the HEPA filter during installation. If you suspect that a HEPA filter has been damaged, DO NOT use the enclosure. See Chapter 6 for Replacing the HEPA Filter.

• The HEPA filter will gradually accumulate airborne

particulate matter from the room. The rate of accumulation will depend upon the cleanliness of the room air, and the amount of time the enclosure is operating. With normal usage, the HEPA filters will last two to five years before requiring replacement.

When to Replace HEPA Filters

The HEPA filter in the Purifier Vertical Clean Bench gradually accumulates airborne particulate matter from the room. The rate of accumulation will depend upon the cleanliness of the room air, and the amount of operational time the enclosure is operating. In typical

Product Service 1-800-522-7658

Chapter 6: Maintaining Your Vertical Clean Bench

installations and usage, the HEPA filters will last two to five years before requiring replacement. Replace HEPA filters when downflow velocity drops below the recommended 30-65 fpm velocity and the speed control is adjusted to full speed. Replace HEPA filter if it fails the HEPA Filter Leak Test in Chapter 6.

How to Install a New HEPA Filter

NOTE: Only a qualified certifier should service the HEPA filter.

After the HEPA filter is replaced, the enclosure MUST be certified. See Figure 6-1.

1. Unplug the enclosure and remove the prefilter located on

top.

2. Remove the front panel by loosening the two screws that

secure it.

3. Using a 9/16" deep socket, loosen the filter clamp bolts

located on top. Refer to Figure 6-1.

4. With the clamp bolts loosened, the HEPA filter-clamping

frame should be clear of filter. Carefully pull the filter straight out of the enclosure and discard properly.

5. Cover the surface of the new HEPA filter gasket with a

light coating of silicone grease, if desired.

6. Install the new HEPA filter by pushing it straight into the

Vertical Clean Bench, ensuring that it is correctly oriented with the gasket facing down on the exhaust side of the enclosure.

CAUTION: The filter clamp bolts should only be tightened enough to ensure a proper seal at maximum tightness. The filter gasket should be compressed 50% or less.

7. Tighten the clamp bolts uniformly until the filter gasket is

properly compressed against the frame. Inspect the seal thoroughly before proceeding.

8. Reinstall the front panel and prefilter.

9. Plug the Vertical Clean Bench in and have it checked for

leaks and downflow velocity.

HEPA Filter Leak Test

Purpose

After installing the new HEPA filter, the HEPA filter should be leak checked. This test is performed to determine the integrity of the HEPA filter, the filter housing, and the filter seal. Leak testing must be done by a qualified technician with calibrated equipment. Remove the upper perforated diffuser located inside the enclosure by using a Phillips screwdriver to unfasten the screws. (See Figure 6-1). The filter passes the leak test at .01% or better.

Chapter 6: Maintaining Your Vertical Clean Bench

Setting the Downflow Velocity with the Speed Control Adjustment

1. Remove the front panel by loosening the (2) Phillips screws

on top that secure the front panel.

2. The speed control is located on the electrical subassembly

located behind the switched control panel and below the front panel. See Figure 6-1.

3. Adjust the speed control with a small Phillips screwdriver

by turning the screw counterclockwise to increase blower speed or clockwise to decrease the blower speed. The speed control is very sensitive, so proceed with caution.

4. Measure the downflow velocity per the averaging

technique outlined in Chapter 3 and adjust the speed control slowly for the desired speed. Allow the speed to stabilize and re-measure the downflow velocity to confirm.

5. Replace the front panel and tighten the screws.

Options

Calibrate and Operate the Airflow Monitor

Optional Guardian Airflow Monitor

Refer to Figure 6-2 for operation and calibration.

Labconco Airflow Monitor / Airflow Switch Operation

The Guardian Airflow Monitor consists of a circuit board and an airflow switch. This switch indicates airflow as safe or low. It does not provide an actual velocity, but a small setscrew in the back of the sensor can adjust the airflow level that it classifies as “good/safe” or “low/alert.”

The circuit board provides power to the sensor and also contains a “safe (green)” and “alert (red)” airflow LED indicators, as well as a “SILENCE ALARM” button to quiet the audio alarm. When first powered up, the Printed Circuit Board (PCB) will light both red and green LED indicators and sound the alarm to indicate it is working. After 5 seconds, the air monitor will indicate either good or bad airflow based on what the connected airflow switch detects. For low airflow, the unit will wait for 10 seconds after low indications before it sounds both the audio alarm and the red “alert” LED indicator. If

Product Service 1-800-522-7658

Chapter 6: Maintaining Your Vertical Clean Bench

the “SILENCE ALARM” button is pressed, the audio alarm will be silenced, but the red “alert” LED will remain on. The alarm is silenced indefinitely unless an airflow change is detected. If safe airflow is later detected for 10 seconds, the green “safe” LED will be lit and the “alert” (red) LED will be shut off. At any time the airflow is safe/good, one can press the SILENCE ALARM test button and the audio alarm and the red LED will turn on as long as this button is held down. The PCB has also a two-pin connector for use as an external output with isolated relay contacts that close when the red/alert LED is lit (low airflow). These relay contacts are not affected by the “SILENCE ALARM” button.

The PCB is mounted behind the front panel using standoffs and an appropriate label is used to highlight the “SILENCE ALARM” button with clear areas for the red and green LED’s.

By special order, the PCB can be prepared as a factory special with an additional connector for the following external inputs, and having the following possible functions:

• External Alarm allows an external signal to sound the alarm

from the building airflow system of a failed condition.

• Alarm Disable allows an external signal to prevent a “low”

airflow alarm from occurring.

• Night Setback allows an external signal to prevent a “low”

airflow alarm from occurring (not any different from Alarm Disable above other than the terminology.)

• Contact Labconco for ordering information on this special

PCB.

Calibration

1. Ensure the flow switch and alarm circuit board are installed

and operational.

2. Allow the enclosure to operate for at least two minutes.

3. If factory installed, the monitor will alarm at 30±10 fpm

downflow velocity with the average outflow velocity set at 85±10 fpm.

4. To change the factory setting, set the downflow velocity to

the desired alarm condition using the speed control adjustment procedure outlined in Chapter 6. Once the alarm condition is set, use a small screwdriver to turn the adjustment screw on the airflow switch counterclockwise (facing the screw) until the “low” airflow red LED lights and the audible flow alarm sounds.

5. Adjust the downflow velocity to the nominal operating

point required. The green “safe” LED should light.

Product Service 1-800-522-7658

Chapter 6: Maintaining Your Vertical Clean Bench

6. Over time the HEPA filter will load and eventually slow

the downflow velocity. Once the alarm condition is met, simply increase the speed control as outlined in Chapter 6 or replace the HEPA filter if the speed control is maximized.

7. The table below lists typical alarm conditions based on

normal operating conditions. Typical alarm conditions are set at downflow velocities of 10 to 30 feet per minute below the normal operating conditions due to supply air and exhaust air fluctuations, as well as room air cross drafts. Consult your Safety Officer or Laboratory Manager for proper operating speeds.

Initial Certification

The Purifier Vertical Clean Bench has been certified at the factory for an average downflow velocity of 40-55 fpm along with the HEPA Filter Leak Test. The Purifier Vertical Clean Bench should be certified for the proper downflow velocity required by your Safety Officer. It is also a conservative recommendation to perform the HEPA Filter Leak Test again should there be any damage caused during transport.

Re-Certification

Under normal operating conditions, the Purifier Vertical Clean Bench should be recertified at least annually. The certifier should perform the minimum following tests:

• Downflow Velocity Test

• HEPA Filter Leak Test

In addition, the following tests should also be performed at the user’s discretion:

• Measure of Line Voltage and Current

• Smoke Test to determine proper airflow patterns

• Lighting Intensity Test (when appropriate)

• Noise Level Test (when appropriate)

• Vibration Test (when appropriate)

enclosure as the airflow of the system may have changed. If incorrect, adjust the speed control to increase downflow velocity. The HEPA filter may have become loaded. If downflow velocity is correct, calibrate the airflow monitor outlined in this manual in Chapter 6. Lightly clean the airway with clean air. Be careful not to touch sensitive electrical components.

An alarm condition must be continuously present before the audible alarm can be silenced. If flow conditions fluctuate near the alarm set point, the airflow monitor will automatically reset it. Action should be taken to bring the enclosure airflow into proper operating parameters or adjust the alarm set point lower.
