• Installationandmaintenanceofequipmentmustbeperformedbyqualifiedmechanics/millwrights/maintenancepersonnel.

• Installationofanyelectricalequipmentmustbecompletedbyqualifiedelectricians,incompliancewithapplicablecodesandordinances.

BecauseWm.W.Meyer&Sonsisnotalwaysawareoftheapplicationanddoesnotalwayshaveaccesstotheinstallation,yourparticipationinthesafeinstallation,operationandmaintenanceofyourRotaryAirlockFeederiscritical.IfyouhaveanysafetyoroperationalquestionspertainingtothedesignorapplicationsoftheRotaryAirlockFeederweencourageyoutocontactthefactoryat(800)963-4458.

Always CONTROL / DE-ENERGIZE potentially hazardous energy sources when installing and maintaining the Rotary Airlock Feeder, as follows:

1. TheRotaryAirlockFeederproductfamilyusesacommonmechanicalprinciplewhichcreatesaninternalpinchpointinordertofunctionproperly:ametalrotorwithbladesrotatesaroundanaxiswithinametalhousing.

a. TheRotaryAirlockFeedershouldnever be maintained or operated in a manner which could expose personnel to the internal moving parts eitherviatheinlet/dischargeport,anaccessdoorofanykindorviaancillaryequipmentaffixedtotheRotaryAirlockFeeder.To do so will expose personnel to the potential risk of serious injury.

b. Avoidseriousinjurybyalwayskeepinghands,fingers,feetoranypartsofyourbody,looseclothing,andforeignobjectsawayfrominletanddischargeopenings,drivecomponents,auxiliarycomponents,andassociatedequipment.

2. Always de-energize all electrical equipment by Locking Out/Tagging Out power beforeworkingonthisRotaryAirlockFeeder,includingmotors,switches,solenoidsandotherancillaryelectricallypoweredorcontrolledEquipment.Iftheelectricalcomponentsarenotproperlyde-energi ed,thiswillexposepersonneltothepotentialriskofseriousinjury.
