NTRODUCTION

Congratulations on your purchase of a Labconco Intelli-Sense Multi-Speed Blower

(MSB). Your MSB with electronically commutated motor (ECM) has been specifically engineered to meet the demanding requirements of most laboratory ventilation situations associated with fume hood and enclosure exhaust. The outside steel housing of the blower encloses the UL listed ECM motor, shaft, junction box wiring, and bearings. The MSB also includes a fume hood blower control box to be located on top of the fume hood, inlet power control cable, three position switch replacement, and fume hood switch label replacement.

The contaminated air housing of the Coated Steel Blower has a protective phenolic coating. The Fiberglass Blower features a fiberglass reinforced polyester housing and an injection molded polypropylene impeller. The PVC Blower housing is formed out of polyvinyl chloride (PVC) and the impeller wheel is injection molded polyvinylidene fluoride (PVDF). The MSB’s feature cooling vents and weather cover that allow for unrestricted exterior roof mounting. The blowers also feature forward curved impellers to ensure quiet operation and optimum air delivery.

All Multi-Speed Blowers utilize a direct drive ECM motor that uses 1/3 less energy than typical AC belt drive motors. ECM’s run approximately 95% efficient whereas AC motors run about 60% efficient. Multi-Speed Blowers make it easy to size fume hood blower systems as they cover a much broader speed range. For most applications, the Intelli-Sense Blower is typically used for only one fume hood. The Intelli-Sense Multi-Speed Blower with two or three position operation can be used in standby mode or night setback mode and set to exhaust at a minimum flow rate with the fume hood sash closed. Two or three speed blower systems should be considered when the total number of fume hoods does not financially substantiate the start-up costs of a variable air volume (VAV) system.

Two or three position blower systems are less expensive to install and still provide an air volume reduction. Please reference Appendix E for typical laboratory controls with individual Intelli-Sense Blowers. Studies have shown that fume hoods on two or three position systems can reduce air flow (CFM) by 50-70% per year. For example, a 6-ft fume hood operating 24 hours a day at 100fpm (735 CFM

Chapter 1: Introduction

at $7/CFM/Yr) at the 18-in sash height at constant volume can cost $5145 per year to operate, but with a MSB used 4 hours per day and the remaining 20 hours a day in standby mode would cost only $2578 per year to operate, saving $2567 per hood annually. For this example, the $2567 annual savings is 50%.

Your Multi-Speed Blower offers many unique features to enhance performance.

To take full advantage of them, acquaint yourself with this manual and keep it handy for future reference. If you are unfamiliar with how blowers operate, review

Refer to Appendix C: Blower Environmental Conditions for complete environmental conditions and wiring diagram.

Location Requirements

In positioning your blower, care should be taken to make sure that it is away from all other types of air handling equipment (intake fans, air conditioning units, etc.).

Your blower should also include a minimum of 7 ft. of ducting above the roofline to generate proper air dispersion of materials being exhausted through the blower.

Also consider the location of the blower inlet with respect to the hood you are exhausting. Proper planning and layout are essential in selecting a blower location.

Product Service 1-800-522-7658 5


Chapter 2: Prerequisites

Mounting Support Requirements

You must provide vibration isolators, vibration mounting pads, and/or a roof curb support for proper mounting of the blower. Vibration isolators or vibration mounting pads are available from many sources such as a local industrial supply company. Labconco recommends supporting the blower with 5/16" diameter mounting hardware.

Electrical Power Requirements

Please refer to the wiring diagrams in Appendix C. The exterior blower wiring should be terminated at the junction box located inside the blower housing. The outside blower weather cover is removed to access the junction box. The MSB blower is wired according to the specific voltage and terminations on the motor and blower model. Locate the specific wiring voltage for your blower motor on the instruction manual cover and in the charts in Chapter 4: Performance Data and

Safety Precautions. All MSB blowers operate at a maximum of 10 full load amps for 115V and 6 full load amps for 230V.

Controls Wiring Requirements

Please refer to the wiring diagrams in Appendix C. The MSB comes with the

Intelli-Sense MSB Control Box, controls cable, power inlet cable, 3-position switch, and 3-position switch label. The power for the MSB Control Box comes from the light circuit on the fume hood. The controls wiring for the MSB requires a fume hood modification to add the control cable from the 3-position switch/label.

A shielded cable from the roof blower junction box must be run to the MSB

Control Box per the wiring diagram and wiring detail in Appendix C. If needed, refer to the diagram in Appendix E that further depicts the controls needed for a typical laboratory with individual Intelli-Sense blowers.

Connect to the Electrical Supply Source

The main electrical power supply connection for the MSB is made directly at the junction box underneath the outer weather cover and below the ECM motor. Refer to wiring detail and wiring diagrams in Appendix C. Remove the weather cover from the MSB and wire directly to the power wires inside the outside junction box located beneath the ECM motor. A knockout has also been provided on the side of the j-box for this purpose.

Access the j-box by removing the top weathercover of the blower base. This weathercover is held in position by machine screws, and once they have been removed, you will have access to the j-box of your blower.

CAUTION: Inspect the MSB blower nameplate voltage and model number carefully prior to connecting your electrical

! service. The wiring harness determines the voltage. The 115V harness is 7115300 and the 230V harness is 7115301 per wiring diagrams in Appendix C.

ATTENTION: Vérifiez la tension nominale ventilateur MSB et le numéro de modèle attentivement avant de brancher votre service électrique. Le câblage détermine la tension. Le harnais de 115V est 7115300 et le faisceau de 230V est 7115301 par les schémas de câblage à l'annexe C.

The blower base end panel is positioned above the blower base to allow for a continuous flow of cooling air through the motor cavity. Slots and louvers have also been placed on both the front and back of the blower base to provide airflow through this motor cavity. Because there is a gap between the end panel and the base, you will be able to run your electrical conduit directly underneath this panel.

No special cutouts or modifications are necessary.

Adjust the Fan Speeds and Confirm the

Performance of your Multi-Speed Blower/

Hood System

The MSB fan speeds need to be adjusted in the field to allow the hood to operate at the proper face velocity. In order to adjust the blower to the proper speeds, refer to the diagram in Figure 3-9 and follow the procedure below.

1. Ensure the blower is turned on at the roof and the control circuit is installed and powered up.

2. Refer to Figure 3-9 and place the blower switch on the hood to its maximum position.

3. Locate the Intelli-Sense MSB Control Box on top of the fume hood. With a small jewelers screw driver, adjust the MSB “MAX” setting and measure the fume hood airflow with a thermal anemometer at the proper sash height setting. Readjust the MSB “MAX” setting as required to set the face velocity. Counter-clockwise rotation increases the blower speed and corresponding fume hood airflow (CFM) increase.

4. It will be necessary to check the blower wheel shaft speed by removing the weathercover to confirm operation per the blower airflow charts in Chapter 4.

!

HINT: Many times a manual damper is used in the exhaust for fine tuning and operating in the proper portion of the blower airflow chart. For lower airflow volume (CFM) at any RPM, close the damper. Refer to Appendix E that shows a manual damper. Refer to Appendix D that shows a typical blower operating curve with the damper adjusted to different positions.

5. Repeat steps 3 and 4 for MSB “MED/MIN” speed. Decide if operation is for medium or minimum based on fume hood sash position. If “OFF” is desired, then turn “MED/MIN” to lowest setting.

6. Repeat steps 3 and 4 for MSB “MIN/OFF” speed. Decide if operation is for

“minimum” or “OFF” based on fume hood sash position and fume hood airflow requirements.

7. Cycle hood at each blower switch setting and confirm airflow requirements. If necessary, confirm blower shaft RPM on the roof and confirm with blower performance charts in Chapter 4.

8. With fume hood air monitor installed, calibrate airflow monitor and confirm airflow at each speed setting.

9. Replace weathercover over the ECM motor.

Normal Operation

Once your blower has been fully ducted and electrically wired, it is ready for operation. The blower is activated from a switch on the fume hood. For night set back to save energy, fully lower the fume hood sash and select the lowest switch setting. Always monitor your airflow constantly with a fume hood airflow monitor. For best results, use Labconco’s Guardian Digital Airflow Monitor and order from Chapter 7.

Laboratory work can resume when the blower is operational or placed in one of the two higher speeds, so that any prevailing fumes and/or odors can be exhausted from the fume hood effectively. Work must cease prior to turning the blower off or when placed at the minimum setting for night set back.

Chapter 6: Maintaining Your Blower

Bearings

The pillow block bearings on your blower are factory sealed and lubricated. Under normal operation, no further lubrication is required. Excessive lubricating may cause damage to the bearing seal and significantly shorten the life span of the bearing. Refer to Appendix A.

Coupler

The shaft coupler from the ECM motor to the blower wheel shaft can be inspected once a year as needed. Tightening of the coupler screws would indicate possible misalignment or an unbalanced blower wheel. Refer to Appendix A.

Common Service Operations (See drawings in Appendix A Replacement

Parts)

Pillow Block Bearing Replacement

If you need to replace a pillow block bearing on your blower, make sure that the locking collars on the bearings face one another. The setscrews used on the locking collars have been sealed with a removable thread sealant. Thread sealant should be applied when a pillow block bearing is replaced in the field. Refer to

Appendix A.

Motor Replacement

With the power disconnected, remove the upper weathercover, the mounting hardware that supports the ECM motor frame and remove the ECM motor.

Remove both of the wire lead connectors to the motor. Re-install the new motor in reverse order. Refer to Appendix A.

Intelli-Sense MSB Control Box Replacement

With the power disconnected, remove the existing Intelli-Sense MSB Control Box and replace it with the new one. Make all connections per electrical wiring diagram in Appendix C. Then follow the instructions in Chapter 3 to adjust the fan speeds and confirm the performance of your Intelli-Sense Multi-Speed Blower/

Two Main Blower Modifications

There are two main ways to modify the performance of your blower as listed in

Chapter 3: Getting Started. One way is the adjustment of the blower outlet orientation. The other way is the adjustment of the fan speed to fine-tune the performance of your blower/hood system. Refer to Chapter 3 for these instructions. Additionally, all the performance data for your particular blower model number are listed in Chapter 4: Performance Data and Safety Precautions.

Additional Modifications by Adding Ductwork Accessories

There are additional ways to equip your blower by adding any of the accessories on the following pages. To ensure that your blower exhaust system will operate properly, the ductwork and accessories linking your hood and blower must be sized correctly. Along with the accessories listed next are the “equivalent resistance in feet of straight duct” for each accessory. It is necessary to compute the sum of the equivalent resistance factors for each accessory and ductwork length for your entire hood/blower system. Then the blower can be sized properly from the total equivalent resistance for your exhaust system. Blower Sizing

Example: You have selected a Labconco Protector Premier 48 Laboratory Hood at

100 fpm and 725 CFM. The static pressure of the Protector Premier 48 at 100 fpm is 0.22". The exhaust collar of this hood is sized to receive 1" diameter PVC duct directly. In this example, your fume removal system requires 30 feet of straight duct, two 90° elbows and one zero pressure weathercap to adequately exhaust the

Product Service 1-800-522-7658 33



chemical fumes. You will be handling low to moderately corrosive materials, so you have selected a Coated Steel Blower.

The information following for the 90° elbow tells you that each 90°, 12" diameter elbow has the equivalent resistance of 25 feet of straight duct. The zero pressure weathercap has 5 feet of equivalent resistance. The total equivalent feet for the system is:

Feet of straight duct

2 elbows @ 25 feet each

30 Feet

50 Feet

1 zero pressure weathercap @ 5 feet 5 Feet

85 Feet

The chart following converts “equivalent resistance in feet of straight duct” to static pressure. So the static pressure of 85 equivalent feet of 12" nominal duct is equal to (85/10) x 0.011" = 0.094". Now this is added to the hood static pressure of 0.22" for a total system static pressure of 0.314". Look at the performance data in Chapter 4 for Coated Steel Blowers. Refer to the 0.25" to .50" range at 725

CFM since this is closest to 0.314". The chart will lead you to select a Coated

Steel Blower model that is 10" set at 900 RPM or a 12" set at 600 RPM. In this example, models 7061110, 7061112, 7061120 and 7061122 all would work. A manual damper would also provide additional fine tuning of the blower/hood exhaust system.
