Introduction

The. purpose. of. this. manual. is. to. provide. instructions.

that. complement. good. general. practices. when. install-

ing.or.operating.fans.manufactured.by.Twin.City.Fan.&.

Blower..It.is.the.responsibility.of.the.purchaser.to.pro-

vide. qualified. personnel. experienced. in. the. installation,.

operation,.and.maintenance.of.air.moving.equipment.

. Instructions.given.in.the.body.of.this.manual.are.gen-

eral.in.nature.and.apply.to.a.variety.of.models.manu-

factured.by.Twin.City.Fan.&.Blower..Most.units.can.be.

installed.and.maintained.with.the.instructions.given.

. Special. applications. may. require. additional. information..

These. instructions. are. supplied. in. the. form. of. attached.

appendices..Use.the.instructions.in.the.appendix.if.the.direc-

tions.in.this.manual.differ.from.instructions.in.the.appendix.

. As.always,.follow.good.safety.practices.when.install-

ing,. maintaining. and. operating. your. air. moving. equip-

ment.. A. variety. of. safety. devices. are. available.. It. is.

the. user's. responsibility. to. determine. adequate. safety.

measures.and.to.obtain.the.required.safety.equipment.

Shipping and Receiving

All.Twin.City.Fan.&.Blower.products.are.carefully.con-

structed. and. inspected. before. shipment. to. insure. the.

highest.standards.of.quality.and.performance.

. Compare. all. components. with. the. bill. of. lading. or.

packing.list.to.verify.that.the.proper.unit.was.received.

. Check. each. unit. for. any. damage. that. may. have.

occurred. in. transit.. Any. damage. should. be. reported.

immediately. to. the. carrier. and. the. necessary. damage.

report.filed.

Handling

Handling. of. all. air. moving. equipment. should. be. con-

ducted.by.trained.personnel.and.be.consistent.with.safe.

handling. practices.. Verify. the. lift. capacity. and. operat-

ing. condition. of. handling. equipment.. Maintain. handling.

equipment.to.avoid.serious.personal.injury.

. Units.shipped.completely.assembled.may.be.lifted.with.

slings.and.spreader.bars..Use.well-padded.chains,.cables.

or.nylon.straps..On.most.units,.lifting.lugs.are.provided.

for.attaching.chains.(see.Figure.1)..Lift.the.fan.in.a.fash-

ion.that.protects.the.fan.and.fan.coating.from.damage..

Never.lift.a.fan.by.the.inlet.or.discharge.flange,.shafting.

or.drives,.wheel.or.impeller,.motor.or.motor.base,.or.in.

any.other.manner.that.may.bend.or.distort.parts.

. Partial.or.disassembled.units.require.special.handling..

All. parts. should. be. handled. in. a. fashion. which. pro-

tects.the.coatings.and.parts.from.damage..Components.

should.be.handled.such.that.forces.are.not.concentrated.

and.bending.or.distortion.cannot.occur..

Figure 1. Lifting Lug Locations

. Housing.should.be.lifted.using.straps.and.spreaders..

Do.not.distort.housing.or.side.plates.when.lifting.

. Bearing. pedestals. should. be. lifted. using. straps. or.

padded. chains.. Under. no. circumstances. should. an.

attached.or.separated.bearing.pedestal.be.lifted.by.the.

shaft,.bearings,.drives,.motor.or.wheel.

. The. shaft. and. wheel.

assembly. may. be. lifted.

using. a. hoist. and. a.

spreader. with. a. sling.

around.the.shaft.at.points.

nearest. the. wheel. (see.

Figure. 2).. Take. care. not.

to.scratch.the.shaft.where.

the.wheel.or.bearings.will.

be.mounted..Never.lift.or.

support. the. assembly. by.

the.wheel..Always.support.
