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.
general. in. nature. and. apply. to. a. variety. of. models.
manufactured. by. Twin. City. Fan. &. Blower.. Most. units.
can. be. installed. and. maintained. with. the. instructions.
given..Additional.product.and.engineering.information.is.
available.at.www.tcf.com.
. 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.

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..
