. Partial.or.disassembled.units.require.special.handling..
All.parts.should.be.handled.in.a.fashion.which.protects.
the. coatings. and. parts. from. damage.. Components.
should.be.handled.such.that.forces.are.not.concentrated.
and.bending.or.distortion.cannot.occur.
. Housing.should.be.lifted.using.straps.and.spreaders..
Do.not.distort.housing.or.side.plates.when.lifting.
Short Term Storage
If.fan.installation.is.to.be.delayed,.store.the.unit.in.a.
protected.area..Protect.the.fan.and.motor.bearings.from.
moisture.and.vibration.(or.shock.loading).
Long Term Storage
Prior to Storage.–.Motor.bearings.are.to.be.greased.at.
the.time.of.going.into.extended.storage.per.the.motor.
manufacturer’s.specifications..
Storage Procedure. –. Fans. should. be. stored. indoors.
whenever.possible.where.control.over.temperature,.shock.
and. dust. is. reasonably. maintained.. If. units. are. to. be.
stored.outside.in.the.elements,.they.should.be.covered.
with.a.water-resistant.material..Stored.equipment.should.
be.stored.on.a.clean,.dry.floor.or.blocked.up.off.the.
ground. on. blocks. to. prevent. unit. from. setting. in. any.
water. or. directly. on. the. ground.. If. shock. or. vibration.
will.be.present.during.storage,.the.unit.may.need.to.be.
placed. on. some. type. of. vibration. dampening. material.
to.aid.in.preventing.brinelling.of.the.bearing.surfaces.
Periodic Check.–.On.a.monthly.interval,.the.equipment.
should. be. checked. to. ensure. that. it. has. remained. in.
an. acceptable. stored. condition.. The. fan. wheel. should.
be.rotated.several.times.by.hand.while.adding.enough.
grease. to. replenish. the. bearing. surfaces. with. fresh.
grease. and. to. maintain. a. full. bearing. cavity.. Grease.
used.must.be.compatible.with.that.already.supplied.in.
the. motor. and. fan. bearings.. The. fan. impeller. should.
be. left. at. approximately. 180. degrees. from. that. of. the.
previous.month.to.prevent.the.shaft.and.impeller.from.
taking. a. set. in. one. position.. Storage. records. should.
be. maintained. which. indicate. the. above. requirements.
have.been.followed..Consult.the.motor.manufacturer.for.
proper.storage,.space.heater.connection.and.lubrication.
if.the.unit.was.supplied.with.one.
Start-Up.–.When.the.unit.is.removed.from.storage,.all.
bearing.grease.should.be.purged.and.replenished.with.
fresh. grease. as. per. the. lubrication. decal.. The. motor.
should.be.measured.to.verify.that.the.resistance.is.still.
at.a.satisfactory.level.compared.to.the.value.recorded.
prior.to.storage.
Foundations and Supporting Structures
Floor.mounted.fans.should.be.installed.on.a.flat,.level.
surface. with. sufficient. structure. support.. Support. shall.
be.suitable.for.static.and.dynamic.loads.and.foundation.
frequencies. be. separated. at. least. 20%. from. the.
rotational.speed/speed.ranges.
. If.the.fans.are.mounted.on.a.sub-structure,.an.inertia.
base.with.spring.isolator.system.should.be.considered.
. Fans. mounted. to. or. within. a. structure. should. be.
placed. as. close. as. possible. to. a. rigid. member. such.
as. a. wall. or. column.. The. structure. must. be. designed.
for. rotating. equipment;. static. design. for. strength. is.
not. sufficient. to. insure. proper. operation.. Supports. for.
suspended. fans. must. be. cross-braced. to. prevent. side.
sway..Structural.resonance.should.be.at.least.20%.from.
fan.operating.speed.
. Any.ducting.and/or.dampers.with.sleeves.should.have.
independent. support;. do. not. use. the. fan. for. support..
Isolating. the. fan. from. ductwork. with. flex. connections.
eliminates.transmission.of.vibration.
1..Sufficient. structure. must. be. provided. to. support.
weight.of.fan.assembly.
2..Sufficient. restraint. must. be. provided. to. resist. the.
pressure. force. against. the. fans.. Typically. fans. are.
assembled.in.an.application.in.a.modular.fashion.with.
multiple.fans.working.in.parallel..The.cumulative.thrust.
force.must.be.restrained.to.prevent.the.fan.assemblies.
from.leaning.or.tipping.forward..The.force.acting.on.
the.fan.assemblies.is.calculated.as.shown.below.
