INSTALLATION, CONT’D: CASE ADJOINMENT INSTRUCTIONS
4. Case Adjoinment Instructions
>> Warranty is void if improper sealant/urethane is used.
>> Lay generous beads of sealant/urethane as specified.
A. Prior To Adjoinment - Apply Industrial Grade
Urethane Adhesive at Center of Uprights
• Lay a generous bead of industrial grade urethane
adhesive at center of uprights (in non-visible areas).
• This urethane adhesive 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 industrial grade urethane adhesive illustration
below-left.
B. Adjoining Cases - Using Bolts and Nuts
• Use appropriately sized nuts and bolts for each hole.
#1 - Hole is accessible through rear sliding door (if you
are able to avoid gas cylinder, attach bolt); otherwise
start at #2 in bolt/nut attachment process.
#2 - Holes are accessible through rear sliding door.
#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-kick has been removed).
• Tighten nuts securely (but do not over-tighten).
• See 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 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 silicone sealant illustration
below-left.
>> You must reattach toe-kick and
decking after case adjoinment
process is complete.

• Improper alignment can cause air leaks compromising the environment inside the case and create condensation.
• Follow the five steps listed below to assure proper front glass alignment.
• Illustrations shown may not exactly reflect every feature or option of your particular case.
B. Front-to-Back Leveling:
• Place a level on top of case,
perpendicular to the front glass.
• Raise or lower either side of case
by shimming under the rails
(following steps 3 & 4 below).
• Double-check the side-to-side level.
A. Side-to-Side Leveling: Place a level on top of display case (parallel
to front glass). Raise or lower either side of case by inserting shims
under the rails to level the case (following steps 3 and 4 below).
E. Verification:
• After inserting shims, open and shut the front glass.
• Verify (again) that the front glass is properly aligned at both left-hand and right-hand side of

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 follow the
recommended cleaning precautions and instructions.
