Glass
The non-glare glass supplied in your case has a specialized
Anti-Reflective coatings on the surface of the glass. These
coatings reduce the glare from lighting so that the products
in your display are more visible to your customers.
While the anti reflective coatings are durable, they are
susceptible to scratching if abrasive materials or liquids are
used for cleaning. Once the glass surface is damaged, it is
IMPOSSIBLE to restore it to the original finish. The following
materials are recommended for routine cleaning:
Specialized cleaning cloths
• Scotch Brite @ High performance Cloth
manufactured by 3M and available in most grocery
stores. This cloth is washable and may be reused as
long as the cloth stays clean and free from solvents.
• Spontex
®
Microfibre Cleaning Cloth - distributed
by Spontex
®
and available in most grocery stores
under the same name. This cloth is washable and
may be reused as long as the cloth stays clean and
free from solvents.
The cleaning cloths named above will usually remove dust,
grease, oil, and fingerprints without the need for cleaning
fluids. A light spray of the cleaning fluids listed above will
reduce the time required for cleaning. These materials have
been tested and proven to clean the non glare glass without
scratching or damaging the Antireflective coating.
Cleaning solvents
- for more difficult cleaning jobs, these
products are recommended for the cleaning of glass.
Care must be taken where they are used. The solvents
are tested for use on the outside of the glass. No solvent
should be applied directly to food product and food should
be protected from overspray unless they carry the
USDA-A1 ranking.
The food should be covered or the solution should be
sprayed on a cleaning cloth away from the case if it is to
be used inside the case with product present.
The following products will not damage the non-glare
coating on the glass:
• Windex
®
• Glass-Plus
®
• Exceed™ Multi Surface Glass Cleaner - from Kay
Chemical Company, Greensboro, NC
• Warm water
Under no circumstances should the following be used for
cleaning glass:
• Coarse paper towels
• Souring Pads or Powders
• Steel wool or steel fiber materials
• Blades
• Acidic or highly Alkaline detergents
• Fluorine based detergents
lift-up Glass Maintenance
at installation and after replacement:
The top cylinders, which allow the raising and lowering of
the glass, have been carefully tested for proper tension.
However, during shipment, the lubricant inside may have
settled. This settling may cause excessive or uneven
tension on the glass - to the point of breakage.
Before opening the glass for the first time and after installing
new cylinders, it is advisable to perform these three easy
steps before completely raising the front glass.
1. Slowly raise and lower each glass section 6 times,
to a height of 6”.
. Increase the height to 1”, and raise and lower the
glass 6 more times.
3. Finally, raise the glass to it’s full extension. This
should release any settled lubricant in the cylinders,
and prevent any stress on the front glass.
After the case is brought to operating temperature the first
time,
recheck the allen screws on the glass once the
case is in full operation and brought to temperature.
Temperature changes can affect the size and shape of the
materials involved, and can cause changes in the secure
fit of the glass and the clamp.
Cylinders are a wear item.
They are designed:
• To support the glass when fully open
• to allow the glass to close slowly
Have your Service Contractor replace the
cylinders when required.
Glass is heavy and can cause bodily damage. Check
support cylinders for periodic maintenance

Piston cylinders are a wear item. They are designed to
support the glass when fully open and to allow the glass
to close slowly. Glass is heavy and can cause bodily
damage.
Check support cylinders as a part of periodic maintenance.
Have your Service Contractor replace the cylinders if they
show signs of weakness or when otherwise indicated.
