SafeAire Fume HoodsOperation, Maintenance andInstallation Instructions

SAFEAIRE LABORATORY FUME HOODSOPERATION, MAINTENANCE AND INSTALLATION INSTRUCTIONSGENERAL INFORMATIONHamilton is pleased to have had the privilege of furnishingyour laboratory equipment. This is a major investment, andyour equipment is built to withstand extremes of temperature,stress and corrosion provided you give it reasonable care.This manual gives you full information for the operation andcare of fume hoods and other Hamilton equipment items.Utility and fine appearance can be assured for many years byfollowing simple procedures. A regular schedule ofmaintenance will be most effective.GENERALFume hoods are exposed to extremes of temperature, reagentfumes and working surface abuse. Regular care will prolongservice life and insure safe working conditions.The exhaust system and blower of a fume hood must functionproperly for safety. Maintenance personnel should service thefan and motor assembly regularly, lubricate as required, andmake sure that the exhaust system is free from obstructions.Semiannually, accumulated deposits should be removed fromthe impeller blade and housing.A simple test with lighted match or smoke will show if the air isbeing drawn into the hood. More accurate checks of air velocitycan be made with a thermal anemometer. See Inspection andField Evaluation procedure.Table of ContentsGENERAL INFORMATION . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 2–3General . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 2Perchloric Acid Hoods . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 3Hood Identification . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 3INSTALLATION . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 4–19Fume Hood Superstructures . . . . . . . . . . . . . . . . . . . . . . . . . . 4Floor-Mounted Fume Hoods . . . . . . . . . . . . . . . . . . . . . . . . . 5–9HOPEC IV Fume Hoods . . . . . . . . . . . . . . . . . . . . . . . . . . 10–11Air Chamber, Auxiliary Air Fume Hoods . . . . . . . . . . . . . . . . . 11Baffles . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 12–13Safety Shields . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 14–15Blower Enclosures . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 16–18Fume Hood Monitors . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 19Exhaust Filter Assembly . . . . . . . . . . . . . . . . . . . . . . . . . . . . 19Minihelic Gauge . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 19WARNING/OPERATING INSTRUCTIONS . . . . . . . . . . . . . . . . . . . . 20MAINTENANCE AND ADJUSTMENTS . . . . . . . . . . . . . . . . . . 21–27General Maintenance . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 21Fume Hood Inspection . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 21How to Replace Fluorescent Light Tube . . . . . . . . . . . . . . . 21-22Servicing Fume Hood Fixtures . . . . . . . . . . . . . . . . . . . . . . . . 22Cleaning Fume Hood Interiors . . . . . . . . . . . . . . . . . . . . . . . . 22Replacing Sash Glass and Cables . . . . . . . . . . . . . . . . . . 23–25Servicing Supply Chamber Air Filter . . . . . . . . . . . . . . . . . . . . 26Exhaust Filter Replacement . . . . . . . . . . . . . . . . . . . . . . . . . . 26Blower RPM Adjustments . . . . . . . . . . . . . . . . . . . . . . . . . . . 27Manometer, Monitoring Exhaust Filters . . . . . . . . . . . . . . . . . . 27FIELD TESTING . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 28–30TROUBLESHOOTING . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 312Always place equipment and apparatus as far back into thefume hood as possible since this provides greater assurance ofproper fume collection and removal.Large, bulky apparatus or equipment should be placed in thefume hood to permit air flow around it, and never placed so asto interfere with the operation of the baffle system. Raise largeitems an inch or two above work surface. Spilled liquids, acids,or corrosive materials should be immediately wiped up and thesurface neutralized with water or the proper neutralizing agentso as to prevent damage to the work surface and the hoodinterior or to apparatus and equipment installed in the hood.Remember that special fume hoods are required for thehandling of Perchloric Acid. See next page.

SAFEAIRE LABORATORY FUME HOODSOPERATION, MAINTENANCE AND INSTALLATION INSTRUCTIONSGENERAL INFORMATIONPERCHLORIC ACID HOODSHOOD IDENTIFICATIONThe properties of perchloric acid require that a speciallydesigned fume hood be set aside for exclusive use with thismaterial. The hood is equipped with a cold water spray devicefor washdown of the interior surfaces. A trough is placedacross the back of the hood for collection and disposal ofwashdown waters. Operating personnel should be well trainedin the proper handling techniques and be familiar with thecharacteristics of this material.Frequency of washdown, both hood interior and exteriorsystem, is determined by the usage and concentration ofreagents. This can range from a weekly procedure to one thatoccurs after every use. Washdown should always be followedby an inspection to verify that all areas are clean and that thewash system is functioning properly.Some of the hazards of perchloric acid which justify the use ofa special hood shBaffles1. Perchloric acid is a very strong acid, capable of producingsevere burns when in contact with skin, eyes or respiratorytract.2. As an aqueous solution, it can cause violent explosions ifimproperly handled.3. It reacts with other substances to form unstable materialswhich are susceptible to exploding either by impact, friction,or spontaneous combustion.Persons using perchloric acid should be thoroughly familiar withits hazards. Many reported laboratory accidents have involvedless than one gram of reactant. Listed below are some commonsafety practices that should be followed: Spilled perchloric acid should be thoroughly washed awaywith large amounts of water. The use of organic chemicals or materials in the hood shouldbe avoided. Goggles or other effective eye protection should be usedwhenever possible, as well as utilization of the fume hoodsash for additional safety. Gas flames or oil baths should not be used within the hood. Organic chemicals should not be kept in storage areas setaside for perchloric acid storage. A schedule should be made for regular washdown andinspection of hood interior, ductwork and blower to guardagainst a build-up of dangerous perchloric materials. Only a fluorocarbon grease should be used as a blowerlubricant, since any other type is to be considered potentiallyhazardous. Washdown procedure should be performed after completionof usage with all apparatus removed from hood.Dimensions are nominal and illustrations and specifications are basedon the latest product information available at the time of publication.The right is reserved to make changes at any time without notice.3
