INTRODUCTION
This.manual.covers.the.Under-counter.Refrigerators.and.
Freezers..Please.read.this.manual.completely.before.at-
tempting.to.install.or.operate.this.equipment.
Site Preparation
The.installation.site.must.be.cleaned.and.prepared.prior.
to.the.equipment.delivery...
• Refer.to.the.SPECIFICATIONS.and.have.a.licensed.
electrician conrm that all electrical requirements
are satised.
• Conrm that all ooring is structurally strong enough
to.support.the.weight. of.a.fully. loaded.unit;.a.fully.
loaded. unit. can. weigh. as. much. as. 1500. pounds...
Consult with a structural engineer for conrmation if
there is any reason to doubt the oor strength.
• Conrm that adequate ventilation has been provid-
ed,.and.that.the.unit.will.not.be.located.close.to.a.
heat.source.
• For all units on casters, conrm that the oor is level
where.the.unit.is.to.be.located.
RECEIVING AND INSPECTING
Exercise.care.to.prevent.damaging.the.equipment.dur-
ing.unloading.and.on-site.transporting.
1.. Visually. inspect. the. exterior. of. the. package,. skid.
and/or.container..Report.any.damage.to.the.carrier.
immediately.
2.. If.any.packaging.damage.is.noted,.open.and.inspect.
the.contents.with.the.carrier.
3.. If.concealed.damage.is.discovered.after.unpacking.
the equipment notify the carrier. Notication must
be.made.both.in.writing.and.verbally.
4.. Check. the. compressor. compartment. housing. and.
visually inspect the refrigeration package. Conrm
that.the.lines.are.secure.and.the.base.is.intact.
5.. Request.the.required.damage.forms.and.an.equip-
ment.damage.inspection.by.the.shipping.company..
The.inspection.should.be.performed.within.10.days.
from.receipt.of.the.equipment.
6.. Retain. all. crating. material. until. an. inspection. has.
been.performed.or.waived.
Serial Number Location
The.serial.number.of.all.self-contained.refrigerators.and.

Location
All.units.are.intended.for.indoor.use.only..A.fully.loaded.
unit.can.weigh.as.much.as.1500.pounds...Choose.a.loca-
tion with a level oor strong enough to support the total
weight of a fully loaded unit. Reinforce the oor if neces-
sary..
For the most efcient refrigeration, provide good air cir-
culation.around.the.unit..
Inside cabinet
Do.not.pack.the.unit.interiors.so.that.air.circulation.is.im-
peded..The.refrigerated.air.is.discharged.at.the.top.rear.
of the unit. Allow for proper air ow from the top rear to
the bottom of the unit. Obstructions to this air ow can
cause.evaporator.coil.freeze.ups.and.loss.of.temperature.
or overow of water from the evaporator drain pan. The
shelves.have.a.rear.turn.up.on.them.to.prevent.obstruc-
tions to the rear air ow. However, bags and other items
located. at. the. rear. of. the. cabinet. may. obstruct. the. air.
ow.
Outside cabinet
Be sure that the unit has access to ample air ow. Avoid
hot.corners.and.locations.near.stoves.and.ovens..Do.not.
install.the.unit.closer.than.two.inches.from.a.wall..To.pre-
vent.air.obstruction,.do.not.locate.large.boxes.and/or.tall.
stacks.of.product.that.might.obstruct.the.air.exhaust.or.
the.air.inlet.
CAUTION
If the unit is laid on its side or back for any reason,
allow a minimum of 24 hours in the upright position,
beforestart-uptoallowcompressoroiltoowback
to the sump. Failure to meet this requirement can
cause compressor failure, unit damage, and will
void the unit warranties.
Electrical connection
Refer. to. the. amperage. data. provided. in. the. SPECIFI-
CATIONS,.the.serial.tag,.the.local.electrical.code.and/or.
the.National.Electrical.Code..Have.a.licensed.electrician.
conrm that the facility wiring is adequate for the unit and
that.a.protected.circuit.of.the.correct.voltage.and.amper-
age is provided for each unit. Conrm that the unit is
connected.only.to.the.proper.protected.power.source..
DANGER
TURN THE ON/OFF SWITCH TO OFF AND
DISCONNECT THE UNIT FROM THE POWER
SOURCE WHENEVER PERFORMING SERVICE,
MAINTENANCE FUNCTIONS OR CLEANING
THE UNIT.
Leveling
Level.the.cabinet.to.improve.performance,.to.better.align.
the. doors,. to. reduce. uneven. strain. on. the. cabinet. and.
reduce.movement.of.the.contents.on.the.shelves..Use.a.
level.to.level.the.unit.from.front.to.back.and.side.to.side..
Units. supplied. with. legs. have. adjustable. bullet. feet. to.
make.the.leveling.adjustments..If.the.unit.is.supplied.with.
casters,. no. leveling. adjustments. are. available.. Ensure.
the oor is level, where the casters unit is located.

MAINTENANCE
DANGER
TURN OFF THE POWER SWITCH AND
DISCONNECT THE UNIT FROM THE POWER
SOURCE WHENEVER PERFORMING SERVICE/
MAINTENANCE FUNCTIONS AND/OR
CLEANING THE REFRIGERATED AREA.
Refrigerators and Freezers
Clean.the.interior.and.exterior.using.soap.and.warm.wa-
ter. If this is not sufcient, use ammonia and water or a
nonabrasive.liquid.cleaner..When.cleaning.the.exterior,.
always.rub.with.the.stainless.steel.grain.to.avoid.marring.
the nish.
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 specically 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. 12-30%.chromium.which. forms.an. invis-
ible passive lm 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 lm is broken
