Cleaning the air diffusers
The. building’s. ventilation. devices. must. be. cleaned.
regularly
.
.so.as.to.maintain.the.correct.ventilation..Use.a.
dry.cloth.and/or.a.small.brush.in.order..
to. get. into. the. ventilation. outlet. on. the.
device... Where. necessary,. the. device.
can.be.taken.down.to.facilitate.cleaning..
The. dirty. mark. which. may. appear. on.
the.ceiling..near.to.the.device.can.most.
easily.be.removed.using.a.feather.duster.
or. dry. cloth.. Note:. The. device. settings.
must.not.be.changed..Do.not.confuse.the.devices.if.you.
take.down.a.number.of.devices.at.the.same.time.
Cleaning the duct system
The.exhaust.air.ducts.-.and.in.some.cases.the.supply.air.
ducts.as.well.-.may.need.to.be.cleaned.after.a.fairly.long.
period.of.use..Dust.and.dirt.collect.there.over.time,.and.
this.can.impair.the.system.capacity..
Authorised.ventilation..cleaners..should.be.called.to.carry.
out.cleaning..However,.the.occupant.can.easily.clean.the.
first.part.of.the.system.inside.the.device..Remove..the.de-
vice,.then.use.a.vacuum.cleaner.and.-.where.appropriate.
-.a.feather.duster.to.clean.the.bits.you.can.get.at..
Take.care.not.to.change.the.device.settings..
Refit.the.device.in.the.same.location.
Note: Shut down the unit when cleaning devices
or ducts.
