GENERAL DESCRIPTIONThe Carroll APU is a high efficiency air filtration system. It is a complete unit, including filters, optional odorabatement section, optional fire damper, and monitoring and operating controls. The unit may include anintegral exhaust fan section. Otherwise, it will be interconnected to an appropriate fan system provided byCarroll or others. It is Underwriters Laboratories (UL) Listed in both Canada and the United States, under thecategory “Hood and Duct Accessories.”

The units are located downstream from Grease Extractors or Hood and Filter Assemblies, and may be floormounted, suspended in a ceiling space, or outdoor roof mounted.

These units are designed as devices which will effectively and practically:

1. Remove residual airborne flammable particulates, grease, lint, dirt, and smoke from the exhaust airstream,allowing the discharge of kitchen exhaust at locations otherwise unacceptable. In Canada, all exhaustductwork downstream of the filter section can be of conventional non-welded design, rather than theheavy gauge, all welded ducts required by N.F.P.A. 96.

2. Provide means for periodic removal and replacement of air filters and odor removal media (whenemployed).

3. Arrest or otherwise prevent flame or hot gases produced under normal or abnormal conditions in thecooking area from entering the exhaust fan section and discharge duct system, by automatically closing afire damper should the air temperature become excessive. The fire damper is required in Canada and isoptional in the United States.

4. Be capable of containing combustion of contaminants within the unit following the fuse link activation ofthe fire damper.

5. Prevent the development of hazardous temperatures on combustible construction spaced 18-inches fromthe unit.

6. Fully abate or control odors below a nuisance level.

OPERATIONThe exhaust air, from either a high efficiency water wash grease extractor or a high efficiency dry greaseextractor, is ducted directly to the exhaust inlet of the APU. Grease, dust, lint, and smoke particles areremoved by then drawing the air through three increasingly efficient air filtering media sets. The first pass isthrough an array of 4” thick pleated media pre-filters. The second pass is through 95% efficient ASHRAE52.1-92 bag filters, UL/ULC CLASS 1. The third and final pass is through an array of 99% ASHRAE 52.1-92,95% DOP box filters, UL/ULC CLASS 1.

Thereafter, the air is standardly treated for odor control. Odor abatement with the Carroll EnvironAir® APU isaccomplished in one of three ways:

1. Neutralization by exposing the airstream to a chamber misted with EnvironSafe™ odor eliminator whichbreaks down the odor molecules into non-odorous compounds (water, carbon, nitrogen, etc.).

2. Oxidation of odor molecules by passing the airstream through an array of trays housing activated aluminaspheres impregnated with potassium permanganate.

3. Absorption/Adsorption of odor molecules by passing the airstream through an array of trays housingactivated carbon.

Note: A 50/50 blend of activated alumina spheres impregnated with potassium permanganate and activatedcarbon is also available.

A fusible-link fire damper is optionally located at the discharge of the filter section, or at the discharge of theoptional odor abatement section, to arrest or otherwise prevent flame or hot gases produced under normalor abnormal conditions in the cooking area from entering the exhaust fan section and discharge duct system,should the temperature at the fusible link exceed 212°F (100˚C). ONLY UL LISTED FUSIBLE LINKS STAMPEDWITH THIS TEMPERATURE ARE TO BE USED. THEY ARE TO BE INSPECTED SEMI-ANNUALLY, AND REPLACED ANNUALLY.

DESCRIPTION & OPERATION

THREE (3) DISTINCT ELECTRICAL, CONTROL, AND STATUS INDICATOR PANELS ARE PROVIDED:

1. A unit sidewall-mounted three phase Combination Magnetic Motor Starter Panel, (provided only if theAPU is equipped with Carroll’s optional fan/blower section). This panel contains the fan starter andoverloads, a disconnect, fuses, control transformer, and terminal blocks for remote annunciation andcontrol. A TYPE 1 indoor panel is standard and a TYPE 3R outdoor panel is optional. (See Standard WiringDiagrams at the end of this manual.)

2. A unit sidewall-mounted Air Monitor Cabinet, which houses air pressure switches and a firestat. It isinterwired with an ACD or ACW remote status panel to provide status indications and control the operation ofthe APU under certain operating conditions. The pressure switches will shut the exhaust fan off in the eventthat a filter is removed or a Nil Air flow situation exists, due to loaded filters, or in the event of an APU orhood fire damper closure.

The firestat is set at 200˚F (93˚C), and is wired to the ACD or ACW panel to shut the exhaust fan off andactuate an alarm should the set temperature be reached. (See Standard Wiring Diagrams at the end ofthis manual.)

3. An ACD or ACW Status Panel. These are status and control panels remotely located, usually in the kitchenspace. They both provide status indications as described herein. The ACD Panel is used in conjunctionwith kitchen exhaust hoods that don't include their own fan control circuits (usually non-water- washhoods). This panel includes the exhaust fan “On-Off” switch. The ACW Panel is interwired with a separateexhaust fan control, and does not include the fan “On-Off” switch. The ACD/ACW Panels are interwired tothe Air Monitor Cabinet and the Combination Magnetic Motor Starter Panel. A deluxe ACD or ACW StatusPanel is available that provides contacts to the Building Monitor for the various functions of the APU. (SeeStandard Wiring Diagrams at the end of this manual.)

Pushing the start button on the Carroll FWC wash control panel (or other system fan control switch), or onCarroll’s ACD Status Panel, starts the exhaust fan. The warm exhaust air is pulled off the cooking equipment andinto the grease extractor. Grease extraction is accomplished by drawing the exhaust air through a series ofmultiple baffles within the grease extractor. Grease, dust, and lint particles are thrown out of the air stream bycentrifugal force and deposited on the baffle surfaces.

At the end of the day, the fan on/off button is pushed and the exhaust fan is de-energized. (ACD only)

If water-wash grease extractors are used, the water-wash control panel(s) will shut down the exhaust fanand start the wash sequence.

(WITH ODOR CONTROL)

The Carroll EnvironAir® APU Systems use a specially formulated neutralizer (EnvironSafe™) in the odor sprayodor abatement process. EnvironSafe™ is a water-based odor neutralizer consisting of a blend of naturalessential oils derived from plants, including peppermint, lemon and eucalyptus. The essential oils used in theformation have been used regularly in food flavoring and have a long history of safety in their use.

The typical odor-causing molecule from a cooking activity is a microorganism derived from oxygen, water,bacteria, and decomposing organic matter. Such molecules are volatile and very light, and permeate throughoutthe atmosphere rapidly if untreated. When they come in contact with the olfactory organs, an unpleasantsmell results.

During passage through the misting section of the EnvironAir® APU, the odor-causing molecules arecontacted with, and encapsulated by, the neutralizer-rich environment. The resulting high molecular weightof the combined odor-causing microorganisms and neutralizer cause the combination to fall out of theairstream. Bimolecular activity also occurs, whereby oxygen attaches to the odor-causing molecules,breaking them down into water, nitrogen carbon, and other non-odorous simpler compounds.

This is a revolutionary concept in odor control technology. It is a complete system that efficiently andeffectively controls odor as the odor-rich airstream passes through the neutralizer-filled environment of theEnvironAir® APU spray section.

This should not be confused with an odor-masking process, which it is not. In many industries, it is amisconception that an industrial perfume will contribute to the elimination of odors. Industrial perfumes,otherwise known as “masking agents”, simply sit on the odors and ultimately disperse. When the initialeffect of these agents wear off, the odors are found to still exist. On the other hand, with the neutralizer youare actually eliminating the odors by causing them to decompose as briefly described above.

The ingredients in the neutralizer are safe and do not harm the environment. It is food grade approved,natural and safe to the ozone. Its longevity of successful commercial use is also attributable to its extremeeffectiveness and cost competitiveness.

The following procedure should be done to maintain the nozzle's performance:

1. Check the air line, which is connected from the compressor unit to the compression fitting and threadedinto the air inlet side of the nozzle, for any leakage.

2. Check the liquid suction line, which is connected to the liquid inlet side of the nozzle, and ensure that it isimmersed in the odor control solution.

3. If it appears that the nozzle is only blowing air and does not lift up the odor control solution out of thecontainer, do the following:

Remove the cleanout plug from the nozzle body and, using a very thin pin or wire, clean the hole in thefluid cap (orifice) and replace the cleanout plug. Remove the foot valve from the liquid container andinspect screen for clogging. Brush clean if clogged.

When equipped with the optional odor media control section the EnvironAir® APU can effectively control themalodors produced from commercial cooking. The exhaust air stream from the filter section is purified ofgrease, lint, dirt and smoke but can still contain malodors produced from the cooking process. Control ofthese odors is accomplished by passing the exhaust air stream from the filter section through one of the twoodor media control options offered by Carroll.

• Activated Alumina Spheres Impregnated with

Potassium Permanganate - is an oxidizing mediaarranged in steel trays inside the odor controlsection. As the exhaust air stream passesthrough the trays the media causes a chemicalreaction, oxidation, that breaks the odor causingmolecules into harmless oxygen and nitrogen.

• Activated Carbon - is an absorption/adsorptionmedia arranged in steel trays inside the odorcontrol section. As the exhaust air streampasses through the trays the media worksthrough a process of absorption and adsorptionon the odor causing molecules.

Note: A 50/50 blend of these two media is also available.


ODOR MEDIA CONTROL SECTION (OPTIONAL)

Odor Media Trays


10


REPLACING SPENT ODOR MEDIA WITH NEW MEDIAThe odor media trays are arranged in the odor control section in 24” X 24” X 2” and/or 24” X 12” X 2” steeltrays. The number and size of the odor media trays is determined by the nominal APU unit size. The traysare designed with totally removable front panels to facilitate the replacement of the odor media.

The frequency of the odor media replacement is determined by the duration, volume, type of cooking performed, and by the amount, by weight, of odor media housed in the APU. A single pass of trays isstandard. Multiple passes are optionally available to significantly extend the functional media life. Media willneed to be replaced upon awareness of loss of odor abatement.

Emptying and replacing the media is a simple process.

1. Remove the fasteners from the front of each media tray and lift off the front panel.

2. Empty the spent media into an appropriate container.

3. Refill the media tray with new media.

4. Install the front panel and secure with the fasteners.

APU SUGGESTED FILTER SECTION MAINTENANCE SCHEDULE:AT LEAST EVERY MONTH (Heavy usage may require more frequent maintenance)1. Check the APU 4-inch pre-filters; replace as necessary.2. Check 95% ASHRAE 52.1-92 bag filters; replace as necessary.

EVERY THREE MONTHS1. Check APU filters as above.2. Check the 99% ASHRAE 52.1-92, 95% DOP Box Filters; replace as necessary

EVERY SIX MONTHS1. Complete three-month inspection, as above.2. Check integrity of any installed fusible links. On alternate six months, replace all fusible links.

Note: Either directly, or via a service agreement, unit expendables should be immediatelyavailable for replacement. These include a set of drive belts, full filter sets, and odorabatement media or EnvironSafe™ Liquid Neutralizer.

MAINTENANCE INSTRUCTIONS FOR FAN/BLOWER SECTIONNote: The maintenance instructions on pages 22-24 apply specifically to the APU if equipped with theoptional fan/blower section by Carroll. This information may also be appropriate for a fan/blower sectionprovided by others.

Periodically inspect fan scroll and wheel blades for dirt build up, and remove any such build up. If a build upis allowed to accumulate and a portion becomes dislodged, the wheel may go out of balance and causeexcessive bearing wear and premature failure.

When ordering replacement fan assembly parts, provide fan model and serial numbers found on theattached nameplate, along with a complete description of the part required.

V-BELT DRIVES:

Periodically check the belt tension and adjust if necessary. Loose belts will slip over the sheaves and causerapid belt wear and burnout. Excessive tension will overload bearings and cause premature bearing failure.As a rough rule of thumb, applying a fair degree of thumb force to a run of the belt mid-way betweensheaves will result in deflecting the belt about 1/64” per inch of the distance between sheave centers underproper tension. Check the alignment of fan and motor sheaves to ensure they are in line, check motor andfan shafts to make sure they are parallel.

When replacement belts are required, replace with a complete new matched set. Retain old belts foremergency use only. When changing belts, loosen tension. Do not force belts over the sheaves. Spare beltsshould be stored in cool, dark, dry storage.

BELTS AND DRIVES BASICS• Belts are, in general, rated to yield a minimum of 3,000 hours of useful life if all instructions are properly

followed.

• DRIVE ALIGNMENT- Drive alignment is one of the most common sources of drive performance problems.Misaligned drives can exhibit symptoms such as high belt tracking forces, uneven belt wear, high noiselevels, and tensile cord failure. The two primary types of drive misalignment are angular and parallel.

Angular misalignment results when the motor and fan shafts are not parallel. As a result, the belt tensilecords are not loaded evenly, resulting in uneven pressure and accelerated belt wear.

Parallel misalignment results from pulleys being mounted out of line from each other. Parallelmisalignment is of concern with V-type belts because they run in pulley grooves and are unable to free-float on the pulleys. Parallel misalignment can cause the belts to become trapped between the oppositepulley flanges, causing serious performance problems.

BELTS AND DRIVES BASICS (continued)

• BELT TENSION- Proper belt tension is essential tomaximize belt and bearing life. Ideal tension is thelowest tension at which the belt will not slip underpeak load conditions. It is achieved when the beltdeflects 1/64” per inch of centerline distance betweenthe motor and fan shafts, under generous thumbpressure applied to the belt perpendicularly mid waybetween its span. Proper tension will cause the beltsto squeal between drive start up and full RPM. Newbelts will exhibit tension decay, requiring the tensionto be checked frequently during the first 24-48 hoursof operation. Appropriately re-tension when thedeflection is excessive or the belts slip or continue tosqueal after full speed is developed.

1. Measure the span length, K

2. At the center of the belt span (K) apply a force (perpendicularto the span) large enough to deflect the belt 1/64” for everyinch of span length. For example, one deflection of a 100 inchspan would be 100/64 or 1-9/16 inches.

WHEN TO DO

Initial inspection -8 hrs. Secondinspection -24 hrs. Third inspection -100hrs. Periodically thereafter.









WHAT TO DO

Check for belt ride in the groove. In multiple groove drives, belt rideshould be uniform, not more than 1/16” above or below top of sheavegroove. Check groove wear area for wear. Side wall of groove should bestraight, not dished out. Bottom of groove should show no signs of beltcontact.

Check sheave by eye for runout. If runout if excessive, it can easily beseen by visual inspection. If runout is noticeable, check sheave forsource of problem and correct.

Check belts for heat. Ambient temperature should not exceed 140°F.Contact temperatures should not exceed 180°F. Make sure drives areproperly ventilated.

Inspect belts for contaminates such as oil or grease. Wipe belts cleanwith detergent and water. Inspect sheave grooves for buildup of suchmaterial and remove if necessary.

Check belt tension using a belt tension checker or use the simple belttensioning procedure noted above. (see fig. 6)

Check alignment with straight edge, string or mechanist level. Correctalignment to as near perfect as possible.

Check belt sag on slack slide of drive. All belts should have a slightbow. If this bow is not uniform with all belts, replace entire set with amatched set.

Check wear surfaces of belt for excessive wear. If belts have a slick,glazed look, belts are slipping. Check drive capacity and belt tension.Never replace only one belt used in a set as used belts will elongate.Replace entire set if replacement is necessary.

Check all setscrews and/or bushing capscrews for looseness. Retightento recommended torque, if necessary.

LUBRICATIONBLOWER BEARINGSBlower shafts turn within various types of bearings, depending on the application and blower type. Themost common type supplied by Carroll is a grease lubricated, heavy-duty, precision anti-friction ball andself aligning pillow block type with lubricating nipples.

NOTE: Too little grease is better than too much. If possible, apply grease to the bearing while it isrunning. Add the grease slowly until a slight bleeding of grease from the seals is noted. At this point,the grease chamber will be filled to approximately 1/3 of its capacity. Using this method, the dangerof over lubricating will be reduced.

NOTE: A fan that is not in use during construction should be manually rotated once a month to keepthe complete bearing well lubricated and to prevent pitting (rusting), often caused by condensation inbearings that are inoperative for long periods of time. Bearings stored outside should be protectedwith heavy polyethylene or equal covering to prevent moisture from entering the bearing housing.

(Fire Condition)

The blower is running but

shuts down, the red FIRE

pilot light illuminates, the

FAN ON/OFF (ACD) or FAN

On (ACW) pilot light goes

off, and the NORMAL pilot

light goes off.

The APU monitoring

system has detected that a

reduction in static pressure

at the APU inlet has

occurred, indicating that

less than the designated

air volume is being

exhausted through the

APU.

The START-UP TIMER is

timing out and shutting

down the system because

the monitor controls did

not proof out.

One of the two conditions

exist: 1. the exhaust

temperature has exceeded

the firestat set point of

200°F (93°C), or 2. the Fire

Test Button located inside

the Status Panel has been

pushed. Either situation

will cause the system to

shut down the blower.

1. Check filters and replace if necessary

2. Check to ensure all doors and panels on the APU areclosed and latched.

3. Check exhaust duct access panel(s) to ensure theyare in place.

4. Check drive belts for slippage.

To determine the exact problem push the Reset buttonon the Status Panel and observe the following:

1. The green FAN ON/OFF (ACD Cabinet) or FAN ON(ACW Cabinet) pilot light illuminates.

2. The LOW AIR, NIL AIR, and FILTER OUT pilot lightsilluminate.

3. As the blower comes up to speed the FILTER OUT,NIL AIR, and LOW AIR pilot lights should go off andthe green NORMAL pilot light should illuminate.

4. If any of the pilot lights for FILTER OUT, NIL AIR, orLOW AIR remain illuminated before the unit shutsdown that light indicates the condition to becorrected.

1. Check for a fire condition in the ventilator orexhaust duct system.

2. Check to ensure that the fire damper in APU unithas not activated.

3. Check for proper exhaust flow.

4. Check filter condition and replace if necessary.


(Fire Condition)

The blower is running but shuts down, the red FIRE pilot light illuminates, the FAN ON/OFF (ACD) or FAN On (ACW) pilot light goes off, and the system locks out.

One of the two conditions exist: 1. the exhaust temperature has exceeded the firestat set point. This situation will cause the system to shut down the blower.

1. Check for a fire condition in the ventilator or exhaust duct system. 2. Check to ensure that the fire damper in APU unit has not activated. 3. Check for proper exhaust flow. 4. Check filter condition and replace if necessary. 5. Reset the panel circuits by switching the panel power supply off and on again.

(Replace Dirty Filter(s)

Condition)

The blower is running and the REPLACE PRE-FILTER, or REPLACE BAG FILTER, or REPLACE BOX FILTER pilot light(s) is illuminated and the audible alarm is activated.

The blower is running but the system has detected that one or more of the filter banks have become loaded and need to be replaced.
