LEVELING
IMPOR TANT! IT IS IMPERA TIVE THA T CASES
BE LEVELED FROM FRONT TO BACK AND
SIDE TO SIDE PRIOR TO JOINING. A LEVEL
CASE IS NECESSARY TO INSURE PROPER
OPERATION, WATER DRAINAGE, GLASS
ALIGNMENT, AND OPERATION OF THE
HINGES SUPPORTING THE GLASS.
LEVELING THE CASE CORRECTLY WILL
SOLVE MOST HINGE OPERATION
PROBLEMS.
NOTE: A. To avoid removing concrete flooring, begin
lineupleveling from the highest point of the
store floor.
B. When wedges are involved in a lineup, set them
first.
C. If there is a problem with the hinge operation,
first check if case is level. The mini top hardware
may have become loosened during shipping
(ESHS Only). If it does not look level, call
Hussmann Chino immediately for the shim kit
needed to level the mini top hardware, and
continue with the following instructions. (If
problem still persists, see "Clamshell Screw
Adjustment" section – ESH only).
All cases were leveled and joined prior to shipment to
insure the closest possible fit when cases are joined in the
field. When joining, use a carpenters level and shim legs
accordingly. Case must be raised correctly, under legs
where support is best, to prevent damage to case.
LEVELING/JOINING INSTRUCTIONS
1 . Check level of floor wher e cases are to be set.
Determine the highest point of the floor; cases will
be set off this point.
2 . Set first case, and adjust legs over the highest part of
the floor so that case is level. Prevent damage – case
must be raised under leg or by use of 2x6 or 2x4 leg
brace. Remove side and back leg braces after case is
set.
3 . Set second case as close as possible to the first case,
and level case to the first using the instructions in
step one.
4 . Apply masking tape 1/8" in from end of case on
inside and outside rear mullion on both cases to be
joined.
5 . Apply liberal bead of case joint sealant (butyl) to
dotted area shown in (Fig.2,#1) of first case. Apply
heavy amount to cov er entire shaded area.
DO NOT USE PERMA GUM!
IGHT-ESH/ESHS-0010
6. Slide second case up to first case snugly . Then lev el
second case to the first case so glass front, bumper
and top are flush.
7 . To compress buytl at joint, use tw o Jurgenson wood
clamps. Mak e sure case is level fr om front to back
and side to side on inside bulkheads at joint.
8 . Attach sections together via a 2 bolts located in the
base of the case. Secure the ov erhead structure by
bolting the bracket, located inside behind lights.
Do not use cam locks
to pull cases together!
9. Apply bead of buytl to top of bulkheads and slip on
stainless steel bulkhead cap. Also apply buytl to
seam between overhead light tubes.
10.VERY IMPOR TANT! Apply liberal amounts of
black buytl to area under interior low er legs and fill
all voids down to bulkhead.
11.Use finger to smooth buytl as thin as possible at
masking tape on inside and outside of rear mullion
(apply additional buytl if necessary). Remov e tape
applied on line #3.
CORNER WEDGES
Corner wedges are attached via fr ont and rear camlocks.
Use a 7mm allen wrench to turn the locks. Do not overtighten! Join the top by using a joint bracket (included in
joint kit) with 3/8" bolts.
COMMON END BETWEEN UNLIKE CASES AND HO T
CASES
Bolt end onto case using bolts provided in predrilled
holes behind front panel through brack et provided,
and in the rear behind the rear access panel on the
bottom. Hot case are only bolted in two places.

ACCESS PANELS
All electrical and drain access panels are clearly labeled
on the deck of the stand. .
INSTALLING SPLASHGUARD
After merchandisers ha ve been leveled and joined and all
electrical and plumbing work has been completed, install
the splashguards. After adjusting brackets flush with the
floor, position splashguard up behind the front panel
first—then position the lower portion over the pr eviously
adjusted brackets. Splashguar ds may be sealed to the floor
using a vinyl cove base trim. The size of trim needed will
depend on how much the floor is out of level.
NOTE: The splashguard must be removable to access compo-
nents behind it.
1. Remove all dirt and wax (etc.) from the area of the
splashguard to ensure a secur e adhesion.
2. Apply a good contact cement to the trim, allowing
for proper dry-time.
3. Install trim to the splashguard so that it is flush with
floor.
Do not seal trim to floor!
BOLT AND SEALANT LOCATIONS
WATER SUPPLY CONNECTION
The well fill water hose on these models will need to be
connected to a water supply. The water connection is 1/
2", and consists of a hand gate valve. If the water pr essure
exceeds 45 psi, a water pressure regulating valve should
be installed in the supply line, and set at 30-35 psi outlet
pressure. The pressure regulating valv e is not supplied by
Hussmann.
For a quick preheat time, the customer may want to
pipe in hot water. If hot water is piped into the case, temperature of water supply must not exceed 150°F(66°C).
In areas where water contains a hea vy mineral content, it
may be a good idea to install a cartridge-type water filtration system.
Proper water depth is 1". These cases come equipped
with an auto-fill system designed to slowly feed in water
to maintain the proper water level, and prevent damage
incurred when cold water is fed too fast into a hot well.
In common well configurations, the water level is regulated by adjusting the probe on the inside of the well. In
multi-well configurations, use the sliding plate at the rear
of the case to adjust the float level. The water lev el is maintained in direct relation to the vertical position of the
plate. The water feeds in slowly, so it is not necessary to
shut water off during cleaning. It is advisable to allow a
number of hours for the system to refill. If necessary, the
case may also be filled manually, with the use of buckets.
NOTE: Some local codes may require the installation of check
valves in the water supply.

Drain is 1" copper. A stub is provided for extending to
sink. Drain must be run in a material that will withstand a
150°F (66°C) (or more) temperature, such as copper.
Do not plumb below the sliding plate
on the side of the hot well!
Doing so may interfere with the
ability to adjust the water within the well!
Damage may occur if cold water is fed
into a preheated hot well too quickly!

User Information
FOOD HANDLING and HOT FOOD EQUIPMENT
These hot tables are for short-term holding and display of
precooked hot foods. They are not intended to cool or
reheat food. The temperature of the food should be
approximately 160°F when first put into the hot table.
These hot tables are best suited when used in a cafeteria
type application where the food is held and served rapidly ,
within a few hours. Any attempt to use the hot table to
display large amounts of food for long periods of time will
result in dehydrated, overcooked and unsafe food. The
quality of food will progressively worsen as the length of
time increases.
The deterioration of product quality is a function of time
and temperature. All products are affected even though
in a gravy or other liquid. They may appear to withstand
the temperature better than “dry” foods such as fried
chicken but this is not necessarily true. ALL foods will
continue to be affected by prolonged exposur e to elevated
temperatures.
The following guidelines are provided only as a general
6
Rev. 0010
guide for the use of this equipment. The local health agency
for your area can provide specific temperature
requirements.
Critical attention must be given to the heat controls for
these hot tables. Both the upper and lower heat controls
must be adjusted to achieve proper food temperatures.
Hot foods should be held at a minimum temperature of at
least 140°F (60°C) according to 1995 FDA Food Code.
However, increasing the temperature too high will also
cause the food to over cook, dry out, lose its fla vor , texture
and color. Food held for prolonged periods at high
temperatures will also lose some of their nutritional value.
Different foods will r equire different contr ol settings. The
type of food, the quantities of f ood and length of time that
it is to remain in the hot table must be considered when
establishing control settings. Therefore, it must be the
user’ s responsibility to establish the correct contr ol settings
to maintain the food at the safest, tastiest and most saleable
condition.
Food temperatures can be accurately determined only through the use of food thermometers!
IMPORTANT OPERATION TIPS:
* Preheat case 30 minutes before loading product
using higher settings. Self Ser vice griddle type
merchandiser using Granite tiles require a longer
preheat period.
* Never place food directly into warmer. Always use
an inset and pan.
* Never pour water into a dry preheated warmer.
This may damage the unit. Always pour water into
warmer BEFORE preheating.
* Always use water in case wells, as it provides even
heat and humidity .
* Too much water or too much heat will cause
excessive condensation on the front glass,
decreasing visibility .
* Make sure all pans are in the w ell units no matter the
configuration.
Using thermometer, check product before
*
loading in case (150°-160°).
* Always use warmer in wet operation when warming
thick food items.
* Stir thick foods such as chili, fudge and chowders
often to keep foods uniformly heated and prevent
scorching.
* At start, set wells to "7", and overhead heat to "5".
After loading, recheck temperature every 1/2 hour
to see that unit is operating properly. Adjust the
thermostat (a higher number for hotter and a low er
number for cooler) to maintain product
+
temperature of 140°F
(60°C.) minimum. The setting
will depend on the type of product being displa y ed
and how much there is in the well. Be sure to test
product temperature with a thermometer
frequently for good pr oduct maintenance.
* Keep cov er(s) on insets to maintain food quality and
temperature.
* Food must always be placed into a displa y pan ov er
the well, ne ver directly into the w ell.
* Food should not be stacked above the top of the pan.
Food above the top of the pan will dry out rapidly .
* Food juice or gravy should be stirr ed frequently and
any meats should be basted with the gravy. Stir and
rotate foods as needed. Wipe up spills immediately
- for eye a ppeal now, and easier cleaning later .
* Food should be rotated periodically from the
bottom to top.
* If practical, the food should be cov ered during slow
sale periods to reduce dehydration.
* At end of the day , r emove product and let case cool.
Then clean with soap and water (use oven cleaner
on the difficult spots). Polish and clean glass with a
good glass cleaner .
All griddle type units are designed to maintain
termperatures above the FDA guideline of 140°F. This is
product temperature, not air or griddle temperatur e. Due
to the open design of these units, they must be loaded
with product for pr oper operation. When units are empty ,
they experience rapid rise of heated air from air outside
the case. This action gives empty units a false, lower than
desired, temperature reading. Loading the case traps the
air at the griddle, raising temperatures to the 165°F to
185°F range, keeping product well above the FDA
guidelines. Remember, these units must be loaded with
product to maintain safe product temperature.*
Food must be displayed in a single layer in direct contact
with the griddle at all times.
CONTROLS
The controls to regulate the temperature of the well
heaters, griddle, and the overhead heat ar e located at the
rear of the case.
OVERHEAD HEATING SYSTEM
Tubular heating units are located above each well to
provide top heat. To obtain the proper food temperatures, the well heaters, griddles, and heat lamps must be
adjusted. Maximum limits should be avoided to prevent
overcooking or drying out food.
WELL HEATING SYSTEM
The heating well is thermostatically controlled with an
indicator light showing when the heater has cycled on and

1. Close drain valve.
2 . Turn all black toggle switches (Water, Fill, Lights) on.
The well will begin to fill appro ximately 15 seconds
after the switch is turned on. Fill to 1" depth.
Damage may occur if cold water is fed
into a preheated hot well too quickly!
3. T urn all overhead heat to the "5" position.
4. After the w ell has begun to fill, turn the w ell heater
and griddle dial to the "7" position.
Do not turn on the well heater
if there is no water in the unit
or damage will occur!
5. Place empty pans in the case to help the case pr eheat
faster . The unit will take appr oximately 45 minutes to
preheat. It is also impor tant that the small pan
divider bars are installed properly betw een each pan.
These dividers provide a seal ar ound each individual
pan and are necessary to maintain the proper
temperature of the food products. Extra dividers
should be stored outside of the case.
IGHT-ESH/ESHS-0010
SHUTDOWN
1. Remove all usable food.
2. T urn off all heat and light controls.
3. T urn well heater contr ol to off.
4. Open water drain to drain water from the well. In its
open position, the valve handle will point in the same
direction as the drain pipe.
5. Thoroughly clean all stainless steel surfaces by
washing them down with a mild soapy solution with
a bacteria killing agent. NOTE: When cleaning hot
well area, pay special attention to the auto-fill sensor .
It should be kept clean or the water in the w ell could
possibly fill to capacity and overflow. Clean
occasionally with a mild cleaning solution. Wiping it
dry will help ensure that the sensor operates
properly.
6. Wipe down non-glass areas on the outside of the
case.
CASE CLEANING
Long life and satisfactory performance of any equipment
are dependent upon the care given to it. To insure long
life, proper sanitation and minimum maintenance costs,
the fixture should be thoroughly cleaned frequently. The
interior bottom may be cleaned with any domestic soap
or detergent based cleaners. Sanitizing solutions will not
harm the interior bottom, how ever , these solutions should
always be used accor ding to the manufacturer’ s directions.
It is essential to establish and regulate cleaning procedur es.
This will minimize bacteria causing discoloration which
leads to degraded product appearance and significantly
shortening product shelf life.
Soap and hot water are not enough to kill this bacteria. A
sanitizing solution must be included with each cleaning process to eliminate this bacteria.

Rev. 0010
User Information cont.
1. Scrub thoroughly , cleaning all surfaces, with soap and
hot water .
2. Rinse with hot water, but do not flood.
3. Apply the sanitizing solution according to the
manufacturer’ s dir ections.
4. Rinse thoroughly.
5. Dry completely before resuming operation.
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.
NON-GLARE GLASS
The high optical clarity of this glass is possible due to
special coatings on the glass surface itself. To preserve
this coating and the optical clarity, keep the glass clean.

Windex
or Glass Plus® are the only solutions recommended to be used to clean the non-glare glass. The
damage to the glass from improper, caustic solutions is
irreparable.
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 v ery effective in not only cleaning and polishing the Plexiglass surface, but also providing
anti-static and anti-fog capabilities. This pr oduct also seals
pores and provides a protective coating.
• DO NOT USE ABRASIVES OR STEEL WOOL SCOURING PADS
(these will mar the finish)
®
In addition to cleaning the glass with the recommended
product, there are precautions that should be taken when
working and cleaning the inside of the case.
• When cleaning the inside of the cases, we
recommend that the glass be fully opened and
covered to prevent solutions from splashing onto
the glass and ruining the coating on the inside.
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)
PLEXIGLASS & ACRYLIC CARE
Improper cleaning not only accelerates the cleaning cycle
but also degrades the quality of this surface. Normal dail y
buffing motions can generated static cling attracting dust

IMPORTANT!
READ BEFORE RAISING FRONT GLASS :
The top cylinders, which allow the raising and lo wering
of the glass, have been carefully tested for proper tension. However, during shipment, the clamshell screws
can work themselves out and/or the lubricant inside ma y
have settled. This settling may cause excessive or uneven
tension on the glass - to the point of breakage.
Before Rasing the Glass retighten all
screws along clamshell!
After installing new cylinders, it is advisable to perf orm
these three easy steps before completely raising the fr ont
glass.
1 . Slowly raise and low er 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.
3. Finally , raise the glass to it's full extension. This
should release any settled lubricant in the cylinders,
and prevent an y stress on the front glass. (1)(3)

IF GLASS DOES NO T CLOSE/STA Y OPEN PROPERLY-
LEVEL MINI TOP HARDWARE
During shipping, it is possible that the mini top hardware
housing the pistons and armature has been jostled out of
position. This affects the opening angle of the glass.
1. Be sure mini top hardware is level front to back b y
placing a level along the top of the mini top housing
at each hinge location. If it is not, y ou will need
a shim kit before y ou can correct. Order fr om
Hussmann Chino.
2. Remove top glass and panel at top of hardware
housing.
3. Mark position of hardware (glass) in r elation to case
before loosening hex screw using masking tape
applied on mini top hardware and case, and pen. Hex
screw allows r ealignment of glass angle and position
front to back.
4. Raise glass and loosen hex screw . (See item/diagram
#6 on page 13.)
5. Shim to adjust until level using shims available from
Hussmann Chino (16 or 20 gauge stainless steel).
6. Check angle by using lev el placed on top of mini top
hardware. Note: a 6" level will fit perfectly within
access area.

7. Remove 1
/4" chrome cap at front of case arm
support. The r emoval of this cap allows finger access
to hold nut plate while tightening hex screw .
8. Hold nut plate and tighten hex screw.
9. If there is still a problem with glass sta ying open over level by adding an ad dition shim under front of case.
NOTE: BEFORE MAKING ANY OF THE

RECOMMENDED ADJUSTMENTS,
VERIFY THAT THE CASE(S) HAVE BEEN LEVELED PROPERLY.TIPS & TROUBLESHOOTING
Before calling for service if something seems wrong, check the following:
1. INSPECT THE GAP BETWEEN THE GLASS PANELS
A. If pinched at the top:
Back or Top edges of glass
Gap is more narro w at the top than at the bottom.
Then see Item 4 / Uneven Gap .
Front or Bottom edges of glass
B. If pinched at the bottom:
Gap is more narr ow at the bottom than at the top.
Then see Item 4 / Uneven Gap
Back or Top edges of glass (hinge side)

C. If gap is even, but too narrow or too wide and conditions ar e satisfactory then:
Front or Bottom edges of glass

2. CHECK CLOSING ACTION OF THE GLASS PANEL
Test each panel by gently pushing it to close. Does the glass panel bounce or wobble as it closes?
A glass panel that does not close smoothly and neatly ,
most likely is misaligned with the front edge of the
glass and the surface or edge which it closes upon.
Refer to diagram at the right.

closes upon)

3. CHECK OPENING ACTION OF GLASS PANELS
A. Lift up adjacent glass panels at the same time
and note the following:
B. Do the corners of the glass maintain an ev en gap
throughout the tra vel of the panels? And do the
corners touch or overlap at any point?
To correct problem
Go to items 4 & 5.

As this diagram indicates, raising the middle
hinge draws the bottom edges closer together.
Whereas lowering the hinge widens the gap .

Which hinge(s) should I adjust first?
In most cases the center hinge is the first candidate,
but if it cannot be adusted because, either the
adjusment screw is max ed out or no additional shims
can be added or removed, then obviously the outer
hinges must be adjusted

AND OPENING OVERLAP PROBLEMS
ADJUST HINGES FRONT – BACK.
A. Adjust center Hinge (Outer hinges
stationary)
As this diagram indicates, pulling the
middle hinge further back, pulls the inside
edges closer to the surface or edge which
the glass rests upon. And pushing the
middle hinge to the front, pushes the
inside edges further away fr om the
surface or edge which the glass rests
upon.

B. Adjust outside hinges (Center hinge
stationary)
As this diagram indicates, pulling the
outside hinge further back, pulls the
outside edge closer to the surface or edge
which the glass rests upon. And pushing
the middle hinge to the front, pushes the
inside edges further away fr om the
surface or edge which the glass rests
upon.
Which hinge(s) should I adjust first?
In most cases the center hinge is the first candidate, but if the arm/mini-cam is at its maximum or minimum position,
then obviously the outer hinges must be used.
