CLEANING THE REFRIGERATED AREA.
Refrigerators and Freezers
Clean.the.interior.and.exterior.using.soap.and.warm.wa-
ter. If this is not sufficient, use ammonia and water or a
nonabrasive.liquid.cleaner..When.cleaning.the.exterior,.
always.rub.with.the.stainless.steel.grain.to.avoid.marring.
the finish.
Do.not.use.an.abrasive.cleaner,.it.may.scratch.the.stain-
less.steel.and/or.the.plastic..Abrasive.cleaners.can.also.
damage.the.breaker.strips.and.gaskets.
Cleaning the Condenser Coil
Clean.the.condenser.coil.a.minimum.of.every.90.days..
If.there.is.a.large.amount.of.debris,.dust.or.grease.ac-
cumulation.prior.to.the.90.day.cycle,.reduce.the.cleaning.
cycle.to.every.30.days.
If.the.buildup.on.the.coil.consists.of.only.light.dust.and.
debris,. clean. the. condenser. coil. using. a. brush.. For.
heavier.dust.buildup,.use.a.vacuum.or.compressed.air.
If.heavy.grease.is.present.use.a.refrigeration.degreas-
ing agent designed specifically for the condenser coils.
Spray. the. condenser. coil. with. degreasing. agent. and.
blow.through.with.compressed.air.
Failure. to. maintain. a. clean. condenser. coil. can. initially.
cause.high.temperatures.and.excessive.run.times..Con-
tinuous.operation.with.dirty.or.clogged.condenser.coils.
may.result.in.compressor.failures..Neglecting.the.con-
denser.coil.cleaning.procedures.will.void.any.warranties.
associated.with.the.compressor.
CAUTION
Never use a high pressure water wash for this
cleaning procedure as water can damage the
electrical components located near or on the
condenser coil.
Stainless Steel Care and Cleaning
Stainless. steel. contains. 70-80%. iron. which. will. rust.. It.
also.contains.1-30%.chromium.which.forms.an.invis-
ible passive film over the steel ’s.surface.that.acts.as.a.
corrosion.shield..As.long.as.the.protective.layer.remains.
intact, the metal remains stainless. If the film is broken
or.contaminated,.outside.elements.can.break.down.the.
steel.and.begin.to.form.rust.or.discoloration.
To.properly.clean.stainless.steel,.use.soft.cloths.or.plas-
tic.scouring.pads.
CAUTION
Never use steel pads, wire brushes or scrapers to
clean stainless steel surfaces.
Cleaning.solutions.must.be.alkaline.based.or.non-chlo-
ride.cleaners..Any.cleaner.containing.chlorides.will.dam-
age the stainless steel protective film. Chlorides are also
commonly.found.in.hard.water,.salts,.and.household.and.
industrial.cleaners..If.cleaners.containing.chlorides.are.
used,. be. sure. to. rinse. repeatedly. and. dry. thoroughly.
upon.completion.
Perform.routine.stainless.steel.cleaning.with.soap.and.
water..Extreme.stains.or.grease.should.be.cleaned.with.
a.non-abrasive.cleaner.and.plastic.scrub.pad.(rub.with.
the.grain)..There.are.also.stainless.steel.cleaners.avail-
able.which.can.restore.the.protective.layer.and.preserve.
the finish.
Early.signs.of.stainless.steel.breakdown.may.consist.of.
small.pits.and.cracks..If.these.early.signs.are.present,.
clean thoroughly and apply a cleaner specifically de -
signed.for.stainless.steel.cleaners.to.attempt.to.restore.
the.passivity.
CAUTION
Never use an acid based cleaning solution. In
addition, many food products have an acidic
content which can deteriorate the finish. Be sure
to clean the stainless steel surfaces of all food
products. Common acidic based food items
include; tomatoes, peppers and other vegetables.
