LOCATION
The merchandisers have been designed for use only in
air conditioned stores where temperature and humidity
are maintained at or below 75°F and 55% relative
humidity . DO NOT allow air conditioning, electric fans,
open doors or windows (etc.) to create air currents
around the merchandiser , as this will impair its correct
operation.
Product temperature should always be maintained at a
constant and proper temperature. This means that from
the time the product is received, through storage,
preparation and display , the temperature of the product
must be controlled to maximize life of the product.
UN-CRATING THE STAND
Place the fixture as close to its permanent position as
possible. Remove the top of the crate. Detach the walls
from each other and remove from the skid. Unbolt the
case from the skid. The fixture can now be lifted off the
crate skid. Lift only at base of stand!
EXTERIOR LOADING
These models have not been structurally designed to
support excessive external loading. Do not walk on
their tops; This could cause serious personal injury and
damage to the fixture.
LEVELING
IMPORTANT! It is imperative that cases and
supporting counters be leveled from front to
back and side to side prior to joining. A level
case is necessary to insure proper operation,
water drainage, and plexiglass alignment.
NOTE: A. T o avoid removing concrete flooring, begin
lineup leveling from the highest point of the store
floor.
B. When wedges are involved in a lineup, set them
first.
Installation
All cases were tested at a level state before shipping.
When joining, use a carpenters level and shim enclosing
or supporting cabinet accordingly .
1. Make sure the cabinet you are installing the FC4H
CINNABON on is level.
2. Wire unit according to local codes.

WIRING COLOR CODE
GLASS ADJUSTMENT
During shipment, the lubricant inside the cylinders may
have settled. This settling may cause excessive or uneven
tension on the glass - to the point of breakage. T o avoid
any damage, please follow these three easy steps:
1. Slowly raise and lower each glass section 6 times to
a height of 6 inches.
2. Increase the height to 12 inches, and raise and lower
the glass 6 more times.
3. Finally raise the glass to its full extension, and lower .
These steps should release any settled lubricant within
the cylinders and prevent any stress on the front glass.
GLASS BREAKAGE
MAY OCCUR!
Retighten glass along clamshell
after leveling and first time case
is brought to full operating
temperature!
CASE MUST BE GROUNDED

FIELD WIRING & SERIAL PLATE AMPERAGE
Field Wiring must be sized for component amperes
printed on the serial plate. Actual ampere draw may be
less than specified. Field wiring from the refrigeration
control panel to the merchandisers is required for
refrigeration thermostats. Most component amperes are
listed in the “Case Specs” section, but always check the
serial plate.
Ballasts are located within the access panel that runs the
length of the rear of the case. Refer to diagram below .
Maintenance
PLEXIGLASS & ACRYLIC CARE
Improper cleaning not only accelerates the cleaning
cycle but also degrades the quality of this surface.
Normal daily buffing motions can generated static cling
attracting dust to the surface. Incorrect cleaning agents
or cleaning cloths can cause micro scratching of the
surface, causing the plastic to haze over time.
CLEANING
Hussmann recommends using a clean damp chamois, or
a paper towel marked as dust and abrasive free with
210® Plastic Cleaner and Polish available by calling
Sumner Labs at 1-800-542-8656. Hard, rough cloths or
paper towels will scratch the acrylic and should not be
used.
ANTISTATIC COATINGS
The 210® has proven to be very effective in not only
cleaning and polishing the Plexiglass surface, but also
providing antistatic and anti-fog capabilities. This product
also seals pores and provides a protective coating.
CLEANING PRECAUTIONS
WHEN CLEANING:
Never Use a Cleaning or Sanitizing Solution
that has an OIL BASE (these will dissolve the
butyl sealants) or AMMONIA BASE
(this will corrode the copper components
of the case)
TO PRESERVE THE ATTRACTIVE FINISH:
Do Use Water and a Mild Detergent for
the Exterior Only!
Do Not Use Abrasives or Steel Wool Scouring Pads
(these will mar the finish)
CLEANING GLASS & MIRRORS
Only use a soft cloth and mild glass cleaner for cleaning
any glass or mirrored components. Be sure to rinse and/
or dry completely .
Never use hot water on cold glass surfaces! It
may shatter and cause serious injury! Allow glass
surfaces to warm
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
5
IGFC-CR3H-HTB-1104
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
• Warm water
Under no circumstances should the following be used
for cleaning glass:

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 once the case is in full operation
and brought to temperature.
Temperature changes can af fect the size and shape of
the materials involved, and can cause changes in the
secure fit of the glass and the clamp.
CAUTION
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.
• 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".
2. Increase the height to 12", and raise and lower the
glass 6 more times.
Glass is heavy and
can cause bodily
damage. Check
support cylinders
for periodic
maintenance
