Space and Location Requirements
The.most.important.consideration.which.must.be.taken.
into.account.when.deciding.upon.the.location.of.air-cooled.
equipment.is.the.provision.for.a.supply.of.ambient.air.to.the.
condenser,.and.removal.of.heated.air.from.the.condenser.area ..
Where.this.essential.requirement.is.not.adhered.to,.it.will.result.in.
higher.head.pressures,.which.cause.poor.operation.and.possible.
eventual.failure.of.equipment ..Units.must.not.be.located.in.the.
vicinity.of.steam,.hot.air.or.fume.exhausts .
Another.consideration.which.must.be.taken.is.that.the.unit.
should.be.mounted.away.from.noise.sensitive.spaces.and.must.
have.adequate.support.to.avoid.vibration.and.noise.transmission.
into.the.building ..Units.should.be.mounted.over.corridors,.utility.
areas,.rest.rooms.and.other.auxiliary.areas.where.high.levels.
of.sound.are.not.an.important.factor ...Sound.and.structural.
consultants.should.be.retained.for.recommendations .
Walls or Obstructions
The.unit.should.be.located.so.that.air.may.circulate.freely.and.not.
be.recirculated ..For.proper.air.flow.and.access.all.sides.of.the.unit.
should.be.a.minimum.of.“W”.away.from.any.wall.or.obstruction ..
It.is.preferred.that.this.distance.be.increased.whenever.
possible ..Care.should.be.taken.to.see.that.ample.room.is.left.for.
maintenance.work.through.access.doors.and.panels ..Overhead.
obstructions.are.not.permitted ...When.the.unit.is.in.an.area.where.
it.is.enclosed.by.three.walls.the.unit.must.be.installed.as.indicated.
for.units.in.a.pit .
Multiple Units
For.units.placed.side.by.side,.the.minimum.distance.between.
units.is.the.width.of.the.largest.unit ..If.units.are.placed.end.to.
end,.the.minimum.distance.between.units.is.4.feet .
Units in Pits
The.top.of.the.unit.should.be.level.with.the.top.of.the.pit,.and.
side.distance.increased.to.“2W” .
If.the.top.of.the.unit.is.not.level.with.the.top.of.pit,.discharge.
cones.or.stacks.must.be.used.to.raise.discharge.air.to.the.top.of.
the.pit ..This.is.a.minimum.requirement .
Decorative Fences
Fences.must.have.50%.free.area,.with.1.foot.undercut,.a.“W”.
minimum.clearance,.and.must.not.exceed.the.top.of.unit ....
If.these.requirements.are.not.met,.unit.must.be.installed.as.
indicated.for.“Units.in.pits” .
