CHAPTER 1 INTRODUCTION

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. Please refer to Chapter 8 for Integrated Intelli-Sense Hoods supplied with limit switches for automatic IntelliSense Blower operation. Studies have shown that fume hoods on two or three

Product Service 1-800-522-7658

Chapter 1: Introduction

Original instructions

position systems can reduce air flow (CFM) by 50-70% per year. For example, a 6ft fume hood operating 24 hours a day at 100fpm (735 CFM 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 Chapter 4: Performance Data and Safety Precautions before you begin operating the blower. Even if you are experienced, review Chapter 5: Using your Blower.

If the unit is not operated as specified in this manual it may impair the protection provided by the unit.

CHAPTER 2 PREREQUISITES

Before you install your blower, you need to prepare your site for installation. A dedicated source of electrical power must be located near the installation site.

Carefully read this chapter to learn:

 The location requirements for your installation site.  The mounting support requirements for your installation site.  The electrical power requirements for your installation site.  The fume hood controls, controls wiring, and controls modifications for

your installation site.

 The space requirements for your installation site.

Refer to Appendix B: Blower Dimensions for complete blower dimensions.

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.

Chapter 2: Prerequisites

Original instructions

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 (Belden 9940, 22 GA, 4 conductor shielded or equal) 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 the PVC Blower Drain

The PVC Blower has a 1/2" NPT drain connection in the bottom of the housing. When this connection is used, it should be directed into a proper drain or into the exhaust duct for proper disposal.

CAUTION: Draining the blower housing directly onto the roof may cause damage to your roof due to the corrosive chemicals exhausted.

ATTENTION: Vidange du carter de la soufflante directement sur le toit peut causer des dommages à votre toit en raison des produits chimiques corrosifs épuisé.

Connect to the Blower Outlet

Before proceeding with the blower outlet connection, read the two warnings and follow the suggested pictures listed next:

WARNING: Should your exhaust stack, on the outlet side of the exhaust blower, extend over 7 feet, both guy wires and additional structural supports are required to carry the weight of this ductwork. The guy wires must be substantial enough to support the exhaust stack against high wind velocities. See photos on next page.

ATTENTION: Si votre cheminée d'échappement, sur le côté de sortie du ventilateur d'évacuation, s'étendent sur 7 pieds, les deux haubans et les supports structuraux supplémentaires sont nécessaires pour supporter le poids de cette canalisation. Les haubans doivent être suffisamment importants pour soutenir la cheminée d'échappement contre la vitesse des vents élevés. Voir les photos à la page suivante.

HINT: An exhaust damper either before or after the MSB Blower is very useful for fine tuning the airflow.

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.

NOTE: WHEN THE WIRING FOR YOUR BLOWER HAS BEEN COMPLETED, CHECK FOR PROPER MOTOR ROTATION. THE MOTOR SHOULD OPERATE IN A CLOCKWISE ROTATION AS VIEWED FROM THE SHAFT SIDE TO OBTAIN PROPER ROTATION OF THE IMPELLER WHEEL. WHEN IN OPERATION, THE IMPELLER SHOULD ROTATE COUNTERCLOCKWISE WHEN VIEWED FROM THE BLOWER INLET.

and blower switch label from the fume hood. For simple ON/OFF, skip this step.

7. Ensure that the power to the unit is shut off and then remove the existing

wires to the blower switch. Important: Prevent the existing wires to the blower switch from causing interference with the sash. Attach one jumper 7115400 to the blower cable wire terminals and another jumper 7115400 to the monitor cable terminals.

8. Install the new blower switch label, blower switch, and blower switch

retainer. If needed, blower switch cutout is 0.83" x 1.45" (2.1 cm x 3.7 cm).

9. Connect the MSB Control Cable wires to the new blower switch as follows.

On one half of the switch:

a. Connect the White wire to the top terminal b. Connect the Red wire to the middle terminal. c. Connect the Black wire to the bottom terminal. d. Reference Appendix C and Appendix E for wiring details.

10. If Night Setback mode is desired for an airflow monitor, connect harness

7117700 to the top two terminals on the unused half of the new blower switch. The other end of 7117700 connects to the Night Setback input of the airflow monitor. See Chapter 7.

11. All electrical connections to the roof mounted blower, the MSB Control

Box, and switch wiring should be intact.

12. Restore power to the roof mounted blower and the fume hood.

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.

Safety Precautions

Before attempting any service and/or maintenance on your blower, always disconnect the blower motor from its power source to prevent possible injury. Upon initial start-up, always wear protective eyewear. A qualified technician should certify the blower/hood system before it is initially used. The blower/hood system should be re-certified annually or whenever it is relocated.

Avant de procéder à un entretien et / ou de maintenance sur votre ventilateur, débranchez toujours le moteur du ventilateur de sa source d'alimentation pour éviter tout risque de blessure. Après le démarrage initial, toujours porter des lunettes de protection. Un technicien qualifié doit certifier le système souffleur / capot avant est initialement utilisé. Le système ventilateur / hotte doit être re-certifié chaque année ou chaque fois qu'il est déplacé.

Do NOT contact blower wheel while still in motion.

NE PAS être en contact avec la roué du ventilateur tant qu’il est en marche.

Product Service 1-800-522-7658

CHAPTER 5 USING YOUR BLOWER

Normal Operation

Once your blower has been fully ducted and electrically wired, it is ready for operation. The blower is activated from a manually operated 3-position switch on the fume hood unless configured for Integrated Intelli-Sense Hoods supplied with limit switches for automatic Intelli-Sense Blower operation outlined in Chapter 8. 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.

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/ Hood System. Refer to Appendix A.

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 12" 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 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 30 Feet 2 elbows @ 25 feet each 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.

Sizes and Pressure Losses in Thermoplastic Duct

This chart provides static pressure losses for 10' long duct lengths of various diameters over a range of airflows in CFM for use in sizing hood/blower combinations at 100 feet per minute.

CHAPTER 8 PROTECTOR I-S HOOD

Labconco offers Protector® I-S™ Fume Hood models installed with limit switches for automatic Intelli-Sense Blower operation that change 3 speeds automatically based off the sash position. The Intelli-Sense Blower low speed runs with the rising sash from 0"-3", with the medium speed sash from 4"-19" and the high speed sash from 20"-28"; the medium and high speed sash height positions can be altered by 1" increments in the field between 15" and 20". The limit switches are installed and wired per the automatic operation wiring diagrams in Appendix C. The limit switches replace the manually operated 3-position switch. A Digital Airflow Monitor on the Protector I-S Hood constantly monitors face velocity at all speeds and sash positions to ensure proper hood operation. Note: The integrated Protector I-S Hoods with limit switches are only available from the factory due to the wiring complexity.

The integrated Protector I-S Hood models with limit switches automatically regulate the Intelli-Sense Blower, but independent of any room controls. Room controls such as room pressurization controls depicted in Appendix E are sold separately and are not sold by Labconco. The Protector I-S Hood is primarily used for small hood projects when the number of fume hoods cannot justify a complete variable airflow volume system or VAV. The Protector I-S Hood alters the (RPM) speed of the electronically commutated motor (ECM) blower wheel automatically with the sash position to change speeds. Some VAV systems can degrade and usually have annual service issues, but the Protector I-S Hood with Intelli-Sense Blower is reliable with little maintenance as it has no belts, valves or sophisticated controls systems. The reliable Intelli-Sense Blower has a rated bearing life of 50,000 hours (6 years) at full speed and a test life of over 150,000 hours (over 17 years).

Product Service 1-800-522-7658

Chapter 8: Protector I-S Hood

Original instructions

Please keep in mind that room controls such as room pressurization controls (Appendix E), duct sensors, or hood exhaust volume controls are not included. The variety of room controls MUST BE selected by the building controls engineering department. Note: Room controls are not sold by Labconco. In typical environments the room controls are set to a negative pressure with a range of

-0.01" to -0.05" depending on the application.

The following summarizes the Protector I-S Hood installed with limit switches for automatic Intelli-Sense Blower operation.

 INTEGRATED – Minimal set up, pre-mounted, multi-speed MSB

controller, and pre-wired limit switches.

 INDEPENDENT – No conscious control as blower speeds change

automatically with sash position and room controls work independently. Room controls are sold separate and not sold by Labconco.

 INTELLIGENT – The Integrated Intelli-Sense Hood becomes a Smart

Hood that adjusts 3 speeds automatically based off sash position, has builtin over-amperage adjustment to prevent overheating, provides simple blower sizing, and provides 3 easy speed adjustments (MIN, MED, MAX) based off MIN sash height of 0"-3", MED sash height of 4"-19", and MAX sash height of 20"-28"; the MED and MAX sash heights can be altered by 1" increments in the field between 15" and 20".

Chapter 9: Troubleshooting

Original instructions

PROBLEM

CAUSE

CORRECTIVE ACTION

Contamination outside of fume hood.

Fume hood has improper face velocity

Have fume hood re-certified and check remote blower exhaust system. Hood should have average face velocity of 60-100 fpm depending on application.

Remote blower has excessive vibration.

Improper motor mount.

Review Chapter 2: Prerequisites and Chapter 3: Getting Started. The blower should be mounted on vibration isolators or vibration mounting pads to isolate vibration.

Inspect wheel for damage and appropriate clearance.

Replace damaged wheel or adjust clearance. Check for objects in blower wheel.

Remove objects in blower wheel.

Improper inlet connection.

Review Chapter 3: Getting Started. The blower inlet should be installed with a vibration damper or flexible duct connection.

Fume hood has improper face velocity.

Blower not sized properly.

Review Chapter 7: Modifying Your Blower. Blower Sizing Size the blower properly with equivalent resistance method. Refer to Chapters 4 and 7.

Blower requires RPM adjustment or a manual damper is needed in the exhaust ductwork.

Review Chapter 3: Getting Started Adjust the fan speed and confirm blower performance. See Chapters 3, 4, and 7.
