INSTALLATION, CONTINUED: CASE ADJOINMENT INSTRUCTIONS
4. Case Adjoinment Instructions
>> Warranty is void if improper caulk/sealant is used.
>> Lay generous beads of caulk/sealant as specified.
A. Prior To Adjoinment - Apply Industrial Butyl
Caulk at Center of Uprights
• Lay a generous bead of industrial grade butyl caulk
at center of uprights (in non-visible areas).
• This butyl caulk prevents refrigerated air from
escaping between cases (causing condensation and
reducing refrigeration efficiency) as well as
preventing ants or other insects from entering case.
• See illustration below.
B. Adjoining Cases - Using Bolts and Nuts
• Use appropriately sized nuts and bolts for each hole.
#1 - Hole is accessible at underside of top surface
support.
#2 - Holes are accessible through rear plenum and
behind honeycomb air diffuser.
#3 - Holes are accessible at underside of decking.
Decking must be removed to attach bolts/nuts.
#4 - Holes are accessible at base frame (through front of
case after front toe-kicks have been removed).
• Tighten nuts securely (but do not over-tighten).
• See accompanying illustration below.
C. After Adjoinment - Apply Food Grade Silicone Sealant
To Inner And Outer Seams
• After all nuts/bolts are securely attached to case, apply a
generous bead of food grade silicone sealant at both
inner and outer adjoinment seams.
• When properly applied, this food grade silicone sealant
will prevent water from seeping between cases (into the
case or to the floor) as well as crumbs or other residue
from entering between case seams.
• See illustrations below.
>> You must reattach toe-kick and decking after case
adjoinment process is complete.

AVONITE SURFACE CLEANING, CARE, MAINTENANCE (TO BE PERFORMED BY STORE PERSONNEL)
Avonite Solid Surfaces Cleaning, Care and Maintenance
Taking into account the fact that there are three types of Avonite countertops finishes, the care and
maintenance tips are different.
The Three Finishes are: Satin, Matte and High Gloss
You must determine, based upon appearance, your particular unit’s finish.
1. The Satin finish Avonite countertops should be cleaned with sponge, water and soap. For special
stains you may use a non-abrasive cleanser and a white pad. In order to remove scratches, you
should use 400 grit paper and then 600 grit paper. The area should be cleaned then with the white
pad and the mentioned cleanser.
2. The Matte finish Avonite countertops should be cleaned with sponge, water and soap. Sanding
with 240 grit paper and cleaning with a green pad and abrasive cleanser may help in removing
scratches. Clean the entire matte surface form time to time in order to obtain the initial finish.
3. The High Gloss finish Avonite countertops should be cleaned with sponge, water and soap. For
the persistent stains, you should use polishing compound and soft cloth. Sanding with 400 grit paper
is helpful in the process of removing scratches. This type of surface may need machine polish and
you need to contact the producer, in order to have the original finish of the Avonite countertop.
Additional Maintenance Guidance:
It is highly recommended not to stand on the Avonite countertops and to avoid sliding hard objects
across these surfaces. Paint removers and other harsh chemicals should be avoided even if you
have stubborn stains.
There are special methods of cleaning these stains and none of them include harsh chemicals. You
should use cutting boards and special hot pads as part of your daily routine. Protectors should be
used especially in the case of High Gloss finish, in the case of hard objects and pottery.

27
CLEANING SCHEDULE: STAINLESS STEEL (TO BE PERFORMED BY STORE PERSONNEL)
General Stainless Steel Surface Cleaning (To Be Performed As Often As Needed):
• Certain grades of stainless steel, and some are more prone to corrosion than others.
• Stainless steel can become exposed to a wide variety of contaminants, which if left untreated can cause
stains and rust.
• Stainless steel requires a specific cleaning procedure to maintain its sheen and remain rust-free.
• Wash with a solution of liquid dishwashing detergent and hot water.
• Rinse with pure hot water from spray bottle. Wipe with clean sponge. This will remove soap residue
that can lodge in stainless steel’s microscopic grooves, causing rust.
• Dry with clean, soft cloth or paper towel.
• Caution! To prevent rust, you MUST rinse with pure hot water from a spray bottle while wiping with
clean sponge after EACH cleaning.
• Caution! Never clean with scouring powder or steel wool as they can mar, scratch and/or erode the
surface of stainless steel. When the surface properties of stainless steel have been compromised, rust
can form.
Brightening:
• Method 1: Brighten by polishing with a soft cloth or sponge with a solution of one part vinegar to 2 parts
water in a spray bottle.
• Method 2: Sprinkle baking soda on sponge and rub gently with soft cloth or sponge.
• Caution! To prevent rust, you MUST rinse with pure hot water from a spray bottle while wiping with
clean sponge after EACH cleaning.
• Dry with clean, soft cloth or paper towel.
Removing Streaks or Stains:
• Method 1: Place two teaspoons of rubbing alcohol on a microfiber cloth or pad. Rub the cloth along the
grain of the appliance until the entire area has been wiped. The rubbing alcohol will air dry itself.
• Method 2: Dip soft cloth or sponge in club soda and rub gently over area of concern.
• Caution! To prevent rust, you MUST rinse with pure hot water from a spray bottle while wiping with
clean sponge after EACH cleaning.
• Dry with clean, soft cloth or paper towel.
Polishing:
• Place a dab of olive oil onto clean soft cloth. Spread over area until a light sheen is observed. Use
pressure to “work the oil” into the small grooves in the surface. Apply firm, steady pressure using small
circular motions.
> Dry buff: Remove excess oil with clean cloth or paper towel using small circular motions.
> Wet buff: Use an ounce or white vinegar with clean cloth or paper towel using small circular motions.
> Continue wiping until oily finish has been removed.
• Caution! To prevent rust, you MUST rinse with pure hot water from a spray bottle while wiping with
clean sponge after EACH cleaning.
• Dry with clean, soft cloth or paper towel.
Removing Rust:
• If rust has begun to form, there are a variety of products that can treat it.
• Among these are CLR® (calcium, lime and rust remover) and Chemetall Oakite 33 (rust, oxides and
scale remover).
• Caution! To prevent food contamination, personal injury or further corrosion, carefully observe
and follow the rust removing product’s precautions and instructions.

--- Recommended Cleaning Supplies ---
4. Bleach (Optional)
5. Lemon Juice (Optional)
6. Steel Wool or Sandpaper (Optional)
Please Follow These Instructions To Properly Clean
and Care for Your Butcher Block Surface
1. Wash the countertop with mild soap and water. Regular liquid dish washing
detergent works well. As little as 2 to 3 drops of liquid dish soap to a quart of warm
water is sufficient. Use a clean sponge or dish towel to clean surface. Caution!
Never use an abrasive cleaning solution on ANY wood countertop!
2. Kill bacteria (often left behind by raw meat), with bleach. Add one
tablespoon of bleach into one gallon of warm water. Do not use a
higher concentration of bleach or wood will crack. Immediately rinse the
countertop with this solution to kill any bacteria. This will help prevent
food borne illnesses.
3. Remove tough stains from butcher block by pouring lemon juice on
the surface and letting it soak for several seconds.
4. Dry the butcher block surface with a soft cloth immediately after
cleaning. Do not allow standing water or moist surfaces to remain on
the butcher block. Also, use the soft cloth to dry moist or wet crevices
so that no moisture remains.
5. Varnished countertops do not need oil treatments. Just follow
steps 1 through 4 above for varnished countertops. Maintain
unvarnished surfaces with a non-toxic oil or warm mineral oil
treatments on a weekly basis or whenever you notice the wood drying
or color fading. Ironwood® Gourmet Butcher Block Oil (shown at left)
is food safe. Do not use vegetable oil or sunflower seed oil as the oil
will become rancid and leave odor. Apply mineral oil to the butcher block surface
in thin coats. Allow the oil to permeate the surface for as little as 5 minutes and
as long as six (6) hours. Blot excess oil off the countertop with a soft cloth. Wipe
away the remainder with a paper towel or cotton cloth. Wait 12 hours before
using the counter.
6. Stains on butcher block can be removed with steel wool or sandpaper. Rub on
the surface until stains disappear. Then, coat the surface with mineral oil (see
#5 for instructions).
7. Always use a plastic or metal cutting board on a wood surface
when cutting. Cutting directly
on the butcher block will leave
behind knife marks that will be
difficult to clean or repair.

Butcher Block Cleaning Instructions

CaesarStone® Care & Maintenance
TAKING CARE OF YOUR QUARTZ SURFACE
CaesarStone quartz surfaces blend modern sophistication
and timeless luxury with unbeatable strength and
durability. The ever-lasting finish requires only simple and routine care to maintain its good looks.
MINIMAL MAINTENANCE
Virtually maintenance-free, CaesarStone’s hard, non-porous surfaces require no sealing to renew the
luster and are simple to clean. In most cases, dip a clean, soft cloth into a solution of water and soap
(or mild detergent) solution and wipe away dust, smudges and residue; then rinse with clean water to
remove residue. This simple treatment is usually enough to keep your CaesarStone countertop
looking like new. If necessary, use a non-abrasive soft soap along with a non-scratch or delicate
scrub pad. Afterwards, thoroughly rinse with clean water to remove residue.
STUBBORN STAINS OR DRIED SPILLS
If needed, apply a non-abrasive household cleaners (a non-abrasive cleaner will not dull the surface
shine); rinse to remove residue. To remove adhered material such as food, gum, nail polish or even
dried paint, first scrape away excess material with a plastic putty knife and then use a damp cloth to
remove any marks or residual dirt. For extra-stubborn stains, use a no-scratch Scotch-Brite® pad
along with the non-abrasive cleaner recommended by your local CaesarStone® distributor.
HEAT TOLERANCE
CaesarStone is more heat resistant than other stone surfaces including most granite, marble and
limestone; it is not affected by temperatures lower than 300 °F (149 °C). However, like all stone
material, CaesarStone can be damaged by sudden and rapid temperature changes. Therefore, do not
place hot pots or pans directly placed on the surface. Instead place a hot pad or trivet on the surface
under cooking units such as electric frying pans, crock pots, or roaster ovens.
SCRATCH RESISTANT
CaesarStone is a highly scratch resistant surface; however avoid abuse of the surface by refraining
from using sharp objects such as sharp knives or screw drivers directly onto the surface.
CLEANING AGENTS TO AVOID
• It’s important to be aware that like any other surface, CaesarStone can be permanently damaged
if exposed to strong chemicals and solvents that can damage its physical properties.
• Never clean your CaesarStone surface with products that contain Trichlorethane or Methylene
chloride, such as paint removers or strippers.
• Avoid the use of highly aggressive cleaning agents such as oven/grill cleaners and dishwasher
polishing agents that have high alkaline/pH levels (pH 8.5 or higher).
• Products containing oils or powders may leave a residue and should be rinsed off thoroughly.
Should your surface accidentally be exposed to any of these damaging products, rinse
immediately with clean water to neutralize the effect.
