USER GUIDE
Environmental Requirements
Environmental Requirements
This unit is designed to operate between 50°F (10°C) and
100°F (38°C). Higher ambient temperatures may reduce
the unit’s ability to reach low temperatures and/or reduce
ice production on applicable models.
For best performance, keep the unit out of direct sunlight
and away from heat generating equipment.
In climates where high humidity and dew points are
present, condensation may appear on outside surfaces.
This is considered normal. The condensation will
evaporate when the humidity drops.
CAUTION
!
Damages caused by ambient temperatures of
40°F (4°C) or below are not covered by the
warranty.

WARNING
!
SHOCK HAZARD — Electrical Grounding
Required. Never attempt to repair or perform
maintenance on the unit until the electricity has
been disconnected.
Never remove the round grounding prong from
the plug and never use a two-prong grounding
adapter.
Altering, cutting or removing power cord,
removing power plug, or direct wiring can cause
serious injury, fire, loss of property and/or life,
and will void the warranty.
Never use an extension cord to connect power to
the unit.
Always keep your working area dry.
NOTICE
Electrical installation must observe all state and
local codes. This unit requires connection to a
grounded (three-prong), polarized receptacle
that has been placed by a qualified electrician.
The unit requires a grounded and polarized 115 VAC,
60 Hz, 15A power supply (normal household current). An
individual, properly grounded branch circuit or circuit
breaker is recommended. A GFCI (ground fault circuit
interrupter) is usually not required for fixed location
appliances and is not recommended for your unit because
it could be prone to nuisance tripping. However, be sure
to consult your local codes.
See CUTOUT & PRODUCT DIMENSIONS for recommended
receptacle location.

LEVELING INFORMATION
To comply with applicable federal, state and local
codes, this equipment may need to be caulked to
the oor.
1. Use a level to
conrm the unit is
level. Level should
be placed along top
edge and side edge
as shown.
2. If the unit is not level, adjust the legs on the corners of
the unit as necessary.
3. Conrm the unit is level after each adjustment and
repeat the previous steps as needed.
INSTALLATION TIP
If the room oor is higher than the oor in the cutout
opening, adjust the rear legs to achieve a total unit rear
height of 1⁄8” (3 mm) less than opening’s rear height.
Shorten the unit height in the front by adjusting the front
legs. This allows the unit to be gently tipped into the
opening. Readjust the front legs to level the unit after it is
correctly positioned in the opening.
INSTALLATION
1. Plug in the power/electrical cord.
2. Gently push the unit into position. Be careful not
to entangle the cord or water and drain lines, if
applicable.
3. Re-check the leveling, from front to back and side to
side. Make any necessary adjustments. The unit’s top
surface should be approximately 1⁄8” (3 mm) below
the countertop.
4. Install the anti-tip bracket.
5. Remove interior packing material and wipe out the
inside of the unit with a clean, water-dampened cloth.

CLEANING VS. SANITIZING
This guide will address both the cleaning and the sanitizing
of the unit.
Clean the unit to remove dried food and spills, to prevent
build-up of grime, and to maintain the natural luster
stainless steel surfaces.
Sanitize the unit when exposed to raw meat juice or
human germs such as from a sneeze or being touched by
someone who is ill. Sanitizing the unit can also be part of
regular cleaning routine.
Stainless Surfaces
Stainless door panels, handles and frames can discolor
when exposed to chlorine gas, pool chemicals, saltwater or
cleaners with bleach.
Keep your stainless unit looking new by cleaning with a
good quality all-in-one stainless steel cleaner and polish
monthly. For best results use Claire®Stainless Steel
Polish and Cleaner. Comparable products are acceptable.
Frequent cleaning will remove surface contamination that
could lead to rust. Some installations may require cleaning
weekly.
Do not clean with steel wool pads.
Do not use stainless steel cleaners or polishes on
any glass surfaces.
Clean any glass surfaces with a non-chlorine glass cleaner.
Do not use cleaners not specically intended for
stainless steel on stainless steel surfaces (this
includes glass, tile, and counter cleaners).
If any surface discoloring or rusting appears, clean it
quickly with Bon-Ami®or Barkeepers Friend Cleanser®and
a nonabrasive cloth. Always clean with the grain. Always
®Stainless Steel Polish and Cleaner or
comparable product to prevent further problems.
Using abrasive pads such as ScotchBrite™ will
cause the graining in the stainless steel to
become blurred.
Rust not cleaned up promptly can penetrate the
surface of the stainless steel and complete
removal of the rust may not be possible.
CLEAN INTERIOR COMPONENTS
Use warm or hot water with dish soap to clean all removed
components and interior surfaces. You may use a vinegar and
water solution in place of soap. Proceed to sanitizing.
Note: Cleaning soaps and vinegar solutions are not
sanitizers.
SANITIZE INTERIOR COMPONENTS AND SURFACES
Choose a Commercial Sanitizer Safe for Stainless
Steel
•Read the directions for proper use to ensure that the
surface will actually be sanitized
•Many products require rinsing with water after use,
especially when food will be touching the surface
•Some products require a wait time before rinsing
•Verify the sanitizer you are using is safe for stainless
steel.
Mix Your Own Sanitizer
Isopropyl Alcohol (rubbing alcohol)
1. Fill a clean, empty spray bottle with isopropyl alcohol
2. Spray surface
3. Wait 20 minutes
4. Dampen a non-abrasive cloth with isopropyl alcohol and
wipe down surface
5. Dry surface with a clean dry non-abrasive cloth
Unscented Bleach and Water
1. Create a solution of 1 tablespoon of unscented bleach
with one gallon of water.
2. Submerse small parts for no more than 3 minutes - rinse
immediately and allow to air dry or dry with a disposable
paper towel.
3. Fill a clean, empty spray bottle with bleach solution.
4. Spray surface.
5. After 2-3 minutes, use clean potable water to thoroughly
