LEVELING
IMPORTANT! It is imperative that 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, and
plexiglass alignment.
LOCATION
The refrigerated 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.
NOTE: A. To 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.
JOINING R3H, R3HA, R3 Combo's
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.
1. Check level of floor where 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 cover entire shaded area.
DO NOT USE PERMAGUM!
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.
GLASS BREAKAGE
MAY OCCUR!
Retighten glass along clamshell
after leveling and first time case
is brought to full operating
temperature!
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. To 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.
It is the contractor's
responsibility to install
case(s) according to local
construction and health
codes.
6. Slide second case up to first case snugly.Then level
second case to the first case so glass front, bumper
and top are flush.
7. To compress silicone at joint, use two Jurgenson
wood clamps. Make sure case is level from front to
SETTING AND JOINING
The sectional construction of these models enable them
to be joined in line to give the effect of one continuous
display. A joint trim kit is supplied with each joint.

Rev.0208
1. Never use pipe for condensate drains smaller than
the nominal diameter of the pipe or P-trap supplied
with the case.
2. When connecting condensate drains, the P-trap
must be used as part of the condensate drain to
prevent air leakage or insect entrance. Store plumbing system floor drains should be at least 14" off the
center of the case to allow use of the P-trap pipe
section. Never use two water seals in series in any
one line. Double P-traps in series will cause a lock
and prevent draining.
3. Always provide as much down hill slope (“fall”) as
possible; 1/8" per foot is the preferred minimum.
PVC pipe, when used, must be supported to maintain the 1/8" pitch and to prevent warping.
4. Avoid long runs of condensate drains. Long runs
make it impossible to provide the “fall” necessary for
good drainage.
5. Provide a suitable air break between the flood rim of
the floor drain and outlet of condensate drain. 1" is
ideal.
6. Prevent condensate drains from freezing:
a. Do not install condensate drains in contact with
non-insulated suction lines. Suction lines should be
insulated with a nonabsorbent insulation material
such as Armstrong’s Armaflex.
b. Where condensate drains are located in dead air
spaces (between refrigerators or between a
refrigerator and a wall), provide means to prevent
freezing.The water seal should be insulated to
prevent condensation.
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 overhead structure by
bolting the bracket, located inside behind lights.
9. Apply bead of silicone to top of bulkheads and slip
on stainless steel bulkhead cap. Also apply silicone
to seam between overhead light tubes.
10.Use finger to smooth silicone as thin as possible at
masking tape on inside and outside of rear mullion
(apply additional silicone if necessary). Remove tape
applied on line #3.
CORNER WEDGES
Corner wedges are attached via front 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.
JOINT TRIM
After cases have been leveled and joined, and refrigeration, electrical, and wasted piping work completed, install
the splashguards. Fasten along the top edge, or center, with
#10 X 3/8" sheet metal screws.
D O NOT SEAL JOINT TRIM TO FLOOR!
Installing R3HTO, R3HATO
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
R3HATO on is level.
2. Wire unit according to local codes.
Plumbing
WATER SUPPLY
Tap water contains more minerals and will contribute to
the mineral residue and buildup which may impair the case's
performance and create undesireable cleaning issues. It is
recommended that a 5 micro particle filter be used to
filter the incoming water supply. Be sure to flush the water line before hooking it up to the filter to prevent blocking the filter.
WASTE OUTLET AND P-TRAP
The waste outlet is located off the center of the case on
one side allowing drip piping to be run lengthwise under
the fixture. There are 3 drains in each fixture that can be
easily located.
1-1/2",1", & 3/4" P-traps and threaded adapters are supplied with each fixture. The 3 P-traps must be installed to
prevent air leakage and insect entrance into the fixture.

REFRIGERANT TYPE
NOTE: PVC-DWV solvent cement is recommended.
Follow the manufacturer’s instructions.
The standard refrigerant will be R-22 unless otherwise
specified on the customer order. Check the serial plate
on the case for information.
INSTALLING CONDENSATE DRAIN
Poorly or improperly installed condensate drains can seriously interfere with the operation of this refrigerator,
and result in costly maintenance and product losses. Please
follow the recommendations listed below when installing
condensate drains to insure a proper installation:
PIPING
The refrigerant line outlets are located under the case.
Locate first the electrical box, the outlets are then on the
same side of the case but at the opposite end. Insulate
5

SUCTION
This device is located on the same side as the refrigeration stub. A Sporlan balanced port expansion valve model
is furnished as standard equipment, unless otherwise specified by customer.
3/8" O.D.
5/8" O.D.
NOTE: The standard coil is piped at 5/8" (suction); however,
the store tie-in may vary depending on the number of
coils and the draw the case has. Depending on the case
setup, the connecting point in the store may be
5
/8", 7/8", or 11/8". Refer to the particular case you are
hooking up.
EXPANSION VALVE ADJUSTMENT
Expansion valves must be adjusted to fully feed the evaporator. Before attempting any adjustments, make sure the
evaporator is either clear or very lightly covered with frost,
and that the fixture is within 10°F of its expected operating temperature.
Refrigerant lines should be sized as shown on the refrigeration legend furnished by the store.
Install P-traps (oil traps) at the base of all suction line vertical risers.
Pressure drop can rob the system of capacity. To keep the
pressure drop to a minimum, keep refrigerant line run as
short as possible, using the minimum number of elbows.
Where elbows are required, use long radius elbows only.
MEASURING THE OPERATING SUPERHEAT
1. Determine the suction pressure with an accurate
pressure gauge at the evaporator outlet.
2. From a refrigerant pressure temperature chart,
determine the saturation temperature at the
observed suction pressure.
3. Measure the temperature of the suction gas at the
thermostatic remote bulb location.
4. Subtract the saturation temperature obtained in step
No. 2 from the temperature measured in step No. 3.
3. The difference is superheat.
5. Set the superheat for 5°F - 7°F.
CONTROL SETTINGS
See the “Case Specs” section of this guidebook for the
appropriate settings for your merchandiser. Maintain these
parameters to achieve near constant product temperatures. Product temperature should be measured first thing
in the morning, after having been refrigerated overnight.
Defrost times should be as follows: OFF CYCLE - Consult the Case Specification Section of this guide for defrost settings. The number of defrosts per day and the
duration of the defrost cycle may be adjusted to meet
conditions present at your location.
Evaporator Pressure Regulator
An Evaporator Pressure Regulator is installed in the front
of the self service section to maintain a constant discharge
temperature. It is located at the front right side of the
case, under the fan plenum near the TX Valve.
ACCESS TO TX VALVES & DRAIN LINES
Service Case Temperature Control
MECHANICAL - Remove product from end of case. Remove
product racks. Remove refrigeration and drain access panels
(labeled). TX valve (mechanical only) and drain are located
under each access panel at end of the case.
ELECTRONIC - The Electronic Expansion valve master and
slave cylinder(s) are located within the electrical access
panel(s).
Temperature control in the upper section of the R3 with
the Service Option is done by means of a thermostat and
suction solenoid valve.This controls both temperature and
humidity,
T-STAT LOCATION
T-Stats are located within the electrical raceway. Refer to
diagram below.
ELECTRONIC EXPANSION VALVE (OPTIONAL)
A wide variety of electronic expansion valves and case
controllers can be utilized. Please refer to EEV and controller manufacturers information sheet. Sensors for electronic expansion valves will be installed on the coil inlet,
coil outlet, and in the discharge air. (Some supermarkets
require a 4th sensor in the return air). Case controllers
will be located in the electrical raceway or under the case.
The front Self Service Evaporator has an E.P.R. valve installed to maintain a constant discharge temperature. It is
located in the front at the right side of the case under the
fan plenum near the TX valve.

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.
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.
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.

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.
ELECTRICAL CIRCUIT IDENTIFICATION
Standard lighting for all refrigerated models will be full
length fluorescent lamps located within the case at the
top.
The switch controlling the lights, the plug provided for
digital scale, and the thermometer are located at the rear
of the case mullion.
The receptacle that is provided on the exterior back of
these models is intended for computerized scales with a
five amp maximum load, not for large motors or other
high wattage appliances. It should be wired to a dedicated
circuit.
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
ELECTRICAL SERVICE RECEPTACLES
(When Applicable)
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.
The receptacles located on the exterior of the merchandiser are intended for scales and lighted displays.They
are not intended nor suitable for large motors or other
external appliances.
CLEANING
PRECAUTIONS
BEFORE
SERVICING
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)
Always Disconnect Electrical
Power at the Main Disconnect
when servicing or replacing
any electrical component.
This includes (but not limited to) Fans,
Heaters, Thermostats, and Lights.
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)
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

IGFP-R3H, R3HTO, R3HA, R3Combo-0208
CLEANING GLASS & MIRRORS
User Information
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
Stocking Refrigerated Sections
Improper temperature and lighting will cause serious product loss. Discoloration, dehydration and spoilage can be
controlled with proper use of the equipment and handling
of product. 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.
Hussmann cases were not designed to “heat up” or “cool
down” product—but rather to maintain an item’s proper
temperature for maximum shelf life. To achieve the protection required always:
1. Minimize processing time to avoid damaging temperature rise to the product. Product should be at
proper temperature.
2. Keep the air in and around the case area free of
foreign gasses and fumes or food will rapidly deteriorate.
3. Maintain the display merchandisers temperature
controls as outlined in the refrigerator section of
this manual.
4. Do not place any product into these refrigerators
until all controls have been adjusted and they are
operating at the proper temperature.Allow merchandiser to operate a minimum of 6 hours before
stocking with any product.
5. When stocking, never allow the product to extend
beyond the recommended load limit. Air discharge and return air flue must be unobstructed at all times to provide proper refrigeration.
6. Keep the service doors closed (when applicable).
Refrigeration performance will be seriously affected
if left open for a prolonged period of time.
7. Avoid the use of supplemental flood or spot lighting.
Display light intensity has been designed for maximum visibility and product life at the factory.The use
of higher output fluorescent lamps (H.O.andV.H.O.),
will shorten the shelf life of the product.
REPLACING FLUORESCENT LAMPS
Fluorescent lamps are furnished with a shatterproof protective coating. The same type of lamp with protective
coating must be used if replaced.

EVAPORATOR FANS
The evaporator fans are located at the center front of
these merchandisers directly beneath the display pans.
Should fans or blades need servicing, always replace fan blades
with the raised embossed side of the blade TOWARD THE
MOTOR.
COPPER COILS
The copper coils used in Hussmann merchandisers may
be repaired in the field. Materials are available from local
refrigeration wholesalers.
Hussmann recommends using #15 Sil-Fos for repairs.
TIPS & TROUBLESHOOTING
Before calling for service, check the following:
1. Check electrical power supply to the equipment for
connection.
2. Check fixture loading. Overstocking case will affect
its proper operation.
3. If frost is collecting on fixture and/or product, check
that no outside doors or windows are open—
allowing moisture to enter store.These merchandisers were designed for use in stores were temperature & humidity does not exceed 75° F and 55% H.
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,
8
Rev.0208
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 exposure to elevated
temperatures.
The following guidelines are provided only as a general
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 overcook, dry out, lose its flavor, texture and color. Food held for prolonged periods at high
temperatures will also lose some of their nutritional value.
Different foods will require different control settings.The
type of food, the quantities of food 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 control settings to
maintain the food at the safest, tastiest and most saleable
condition.
* 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". 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 lower number for cooler)
to maintain product temperature of 140°F+ (60°C.)
minimum. The setting will depend on the type of
product being displayed and how much there is in
the well. Be sure to test product temperature with a
thermometer frequently for good product maintenance.
* Food must always be placed into a display pan over
the well, never directly into the well.
* 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 stirred frequently and
any meats should be basted with the gravy. Stir and
rotate foods as needed. Wipe up spills immediately for eye appeal now, and easier cleaning later.
* Food should be rotated periodically from the
bottom to top.
* If practical, the food should be covered during slack
sale periods to reduce dehydration.
* At end of the day, remove 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.
Food temperatures can be accurately determined only through the use of food thermometers!
CONTROLS
IMPORTANT OPERATION TIPS:
The controls are located at the rear of the case.
* Preheat case 30 minutes before loading product
using higher settings.
* 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 well units no matter the
configuration.

NOTE: This equipment is not designed to heat-up or cook food.
Food must be 150° - 160° when put in display.
1. Measure PRODUCT temperature hourly by inserting a food
thermometer into the food. Proper holding temperature is 140°.
2. To change temperature, increase or decrease Overhead Heat
by one number at a time. Adjust the griddle temperature as
necessary. Measure product temperature again in one hour.
Readjust if necessary.
SHUTDOWN
1. Turn all switches and dials to "OFF" position.
2. Allow case to cool before cleaning.

Startup:
1. Turn the Main Power Switch ON. (This will enable all other switches in the case).
2. Turn Lights & Fans Switch ON.
3. Turn Water Fill System ON. (For 100% DRY Heat leave water system OFF).
4. Press “PUMP PRIME” for approximately 10 seconds (optional) to self-prime the humidity system. The water reservoir (pan)
INSIDE the case should ALWAYS be half full.
5. Turn Humidity Control knob to # 7,“STARTUP”, for maximum humidity conditions - over 7 may cause condensation on the glass.
This control will continually pump water into the water reservoir (pan) INSIDE the case
7. Turn Temperature Control knob to # 7,“STARTUP”, for initial temperature settings. (This will guarantee over 140°F safe FDA
temperatures).
Temperature Adjustment:
Adjust temperature up or down as required to maintain safe FDA Hot Food Temperatures.After adjustment, allow adequate time for change to
take place.Allow 30 minutes for product to respond. Although a discharge air temperature of approximately 170°F will guarantee safe food
temperatures throughout the case, use a thermometer to check food temperature periodically according to FDA guidelines.
Humidity Adjustment:
Adjust humidity up or down as desired for the appropriate food texture desired. More humidity for moist foods, less humidity or none for crispy
foods.
Be patient, humidity adjustments to higher or lower levels are not immediate, as existing moisture (or water content) within the hot environment
of the case rises or lowers at a slow pace.

Appendices
APPENDIX A. – Temperature Guidelines
Refrigerated
The refrigerators should be operated according to Hussmann’s
published engineering specifications for entering air temperatures for
specific equipment applications. Table 1 shows the typical temperature
of the air entering the food zone one hour before the start of defrost
and one hour after defrost for various categories of refrigerators.
Refer to Appendix C for Field Evaluation Guidelines.
APPENDIX B. – Application
Recommendations
Refrigerated
1.0 Temperature performance is critical for controlling bacteria
growth. Therefore, the following recommendations are included in
the standard. They are based on confirmed field experience over
many years.
1.1 The installer is responsible for following the installation instructions and recommendations provided by Hussmann for the
installation of each individual type refrigerator.
1.2 Refrigeration piping should be sized according to Hussmann's
equipment recommendations and installed in accordance with
normal refrigeration practices. Refrigeration piping should be
insulated according to Hussmann’s recommendations.
1.3 A clogged waste outlet blocks refrigeration. The installer is
responsible for the proper installation of the system which
dispenses condensate waste through an air gap into the building
indirect waste system.
1.4 The installer should perform a complete start-up evaluation prior to
the loading of food into the refrigerator, which includes such items as:
a) Initial temperature performance, Coils should be properly fed with
a refrigerant according to Hussmann’s recommendations.
b) Observation of outside influences such as drafts, radiant
heating from the ceiling and from lamps. Such influence should
be properly corrected or compensated for.
c) At the same time, checks should be made of the store drybulb and wet-bulb temperatures to ascertain that they are
within the limits prescribed by Hussmann.
d) Complete start-up procedures should include checking through
a defrost to make certain of its adequate frequency and length
without substantially exceeding the actual needs. This should
include checking the electrical or refrigerant circuits to make
sure that defrosts are correctly programmed for all the
refrigerators connected to each refrigeration system.
e) Recording instruments should be used to check performance.
Hot
1.0 The installer should perform a complete start-up evaluation prior to
the loading of food into the hot food case, which includes such items
as:
a) Initial temperature performance, Griddles and Hot Wells.
b) Observation of outside influences such as drafts, radiant
heating from the ceiling and from lamps. Such influence should
be properly corrected or compensated for.
c) Complete start-up procedures should include :
1. Heat / display lamps are lighting
2. Indicator lamps on control panel(s) are working
3. Auto-fill is functioning properly (Service cases)
4. Hot Griddles are functioning.

4. Are the entering air ducts blocked?
5. Is a dumped display causing turbulent air flow and mixing with room air?
6. Are spotlights or other high intensity lighting directed onto the
product?
7. Are there unusual draft conditions (from heating /air-conditioning
ducts, open doors, etc.)?
8. Is there exposure to direct sunlight?
8. Are display signs blocking or diverting airflow?
9. Are the coils of the refrigerator iced up?
11. Is the store ambient over 75°F, 55% RH as set forth in ASHRAE
Standard 72 and ASHRAE Standard 117?
12. Are the shelf positions, number, and size other than recommended
by Hussmann?
13. Is there an improper application or control system?
14. Is the evaporator fan motor/blade inoperative?
15. Is the defrost time excessive?
16. Is the defrost termination, thermostat (if used) set too high?
17. Are the refrigerant controls incorrectly adjusted?
18. Is the air entering the condenser above design conditions? Are the
condenser fins clear of dirt, dust, etc.?
19. Is there a shortage of refrigerant?
20. Has the equipment been modified to use replacements for CFC-12,
CFC-502 or other refrigerant? If so, have the modifications been
made in accordance with the recommendations of Hussmann's
equipment? Is the refrigerator charged with the proper refrigerant
and lubricant? Does the system use the recommended compressor?
Hot
1.0 The most consistent indicator of display hot case performance is
temperature of the product itself.
NOTE: Public Health will use the temperature of the product in
determining if the hot case will be allowed to display potentially
hazardous food. For the purpose of this evaluation, product
temperature above the FDA Food Code 1993 temperature for
potentially hazardous food will be the first indication that an evaluation
should be performed. It is expected that all hot cases will keep food
at the FDA Food Code 1993 temperature to prevent the sale of
potentially hazardous food.
1.1 The following recommendations are made for the purpose of
arriving at easily taken and understood data which, coupled with
other observations, may be used to determined whether a display
refrigerator is working as intended:
a) INSTRUMENT – A stainless steel stem-type thermometer is
recommended and it should have a dial a minimum of 1 inch
internal diameter. A test thermometer scaled only in Celsius or
dually scaled in Celsius and Fahrenheit shall be accurate to 1°C
(1.8°F). Temperature measuring devices that are scaled only in
APPENDIX C. – Field Recommendations Refrigerated
Recommendations for field evaluating the performance of retail
food refrigerators and hot cases
1.0 The most consistent indicator of display refrigerator performance
is the temperature of the air entering the product zone (Refrigerated see Diagram 1, Appendix A). In practical use, the precise
determination of return air temperature is extremely difficult.
Readings of return air temperatures will be variable and results
will be inconsistent. The product temperature alone is not an
indicator of refrigerator performance.
NOTE: Public Health will use the temperature of the product in
determining if the refrigerator will be allowed to display potentially
hazardous food. For the purpose of this evaluation, product
temperature above the FDA Food Code 1993 temperature for
potentially hazardous food will be the first indication that an evaluation
should be performed. It is expected that all refrigerators will keep food
at the FDA Food Code 1993 temperature for potentially hazardous food.
1.1 The following recommendations are made for the purpose of
arriving at easily taken and understood data which, coupled with
other observations, may be used to determined whether a display
refrigerator is working as intended:
a) INSTRUMENT – A stainless steel stem-type thermometer is
recommended and it should have a dial a minimum of 1 inch
internal diameter. A test thermometer scaled only in Celsius or
dually scaled in Celsius and Fahrenheit shall be accurate to 1°C
(1.8°F). Temperature measuring devices that are scaled only in
Fahrenheit shall be accurate to 2°F. The thermometer should
be checked for proper calibration. (It should read 32°F when
the stem is immersed in an ice water bath).
b) LOCATION – The probe or sensing element of the thermometer
should be located in the airstream where the air first enters
the display or storage area, and not more than 1 inch away
from the surface and in the center of the discharge opening.
c) READING – It should first be determined that the refrigerator
is refrigerating and has operated at least one hour since the
end of the last defrost period. The thermometer reading should
be made only after it has been allowed to stabilize, i.e.,
maintain a constant reading.
d) OTHER OBSERVATIONS – Other observations should be made
which may indicate operating problems, such as unsatisfactory
product, feel/appearance.
e) CONCLUSIONS – In the absence of any apparent undesirable
conditions, the refrigerator should be judged to be operating
properly. If it is determined that such condition is undesirable,
i.e., the product is above proper temperature, checks should be
made for the following:
1. Has the refrigerator been loaded with warm product?
2. Is the product loaded beyond the “Safe Load Line” markers?
3. Are the return air ducts blocked?
35
IGFP-R3H, R3HTO, R3HA, R3Combo-0208
Fahrenheit shall be accurate to 2°F. The thermometer should be
checked for proper calibration. (It should read 32°F when the
stem is immersed in an ice water bath).
b) LOCATION – The thermometer must be inserted into the food
itself to acquire proper food pulp temperature.
c) READING – The thermometer reading should be made only
after it has been allowed to stabilize, i.e., maintain a constant
reading.
Loading Product: Cases should be allowed to heat up for one
hour before product is loaded.
Temperature adjustments: Allow 4 hours after adjustment has
been made before testing pulp temperature of product.
d) OTHER OBSERVATIONS – Other observations should be made
which may indicate operating problems, such as unsatisfactory
product, feel/appearance.
f) Minimize the transfer time of perishables from storage to display.
g) Keep meat under refrigeration in meat cutting and processing area
except for the few moments it is being handled in processing. When
a cut or tray of meat is not to be worked on immediately, the
procedure should call for returning it to refrigeration.
h) Keep tools clean and sanitized. Since mechanical equipment is used
for fresh meat processing, all such equipment should be cleaned at
least daily and each time a different kind of meat product comes
in contact with the tool or equipment.
i) Make sure that all refrigeration equipment is installed and adjusted
in strict accordance with Hussmann’s recommendations.
j) See that all storage and refrigeration equipment is kept in proper
working order by routine maintenance.
Hot
1.0 Hussmann should provide instructions and recommendations for
proper periodic cleaning. The user will be responsible for such
cleaning, including the cleaning of equipment within the compartment
and the hot area(s). Cleaning practices, particularly with respect to
proper refrigerator unloading and warm-up, must be in accordance
with applicable recommendations.
1. Allow the case to preheat for one hour prior to loading.
2. Hot foods should enter the case directly after cooking or no
lower than 150° - 160°F. The Hot Cases are not designed to
heat up or cook food.
3. Self Service - be sure to display product in single layer in
direct contact with heating surface and/or wire rack.
4. All griddle type units are designed to maintain termperatures
above the FDA guideline of 140°F. This is product temperature,
not air or griddle temperature. Due to the open design of
these units, they must be loaded with product for proper
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.
5. Check the food pulp temperature frequently with a thermometer to make sure it is at the proper holding temperature. Hot
foods should be at 140°. The thermometer must be inserted
into the food itself for the proper temperature.
6. Do not display more food than will be sold within a 4 hour
period.
7. When restocking, bring older food to the front, and stock
fresher food on top.
8. Clean spills as soon as they happen.
9. Fingerprints and food splatter will drastically shorten bulb life.
Clean splatter off the bulbs immediately with a soft cloth.
When handling bulbs, wear cotton gloves or use a cotton rag /
APPENDIX D. – Recommendations to user
Refrigerated
1.0 Hussmann should provide instructions and recommendations for
proper periodic cleaning. The user will be responsible for such
cleaning, including the cleaning of low temperature equipment within
the compartment and the cooling coil area(s). Cleaning practices,
particularly with respect to proper refrigerator unloading and warmup, must be in accordance with applicable recommendations.
1.1 Cleaning of non frozen food equipment should include a weekly cleaning
of the food compartment as a minimum to prevent bacteria growth from
accumulating. Actual use and products may dictate more frequent cleaning.
Circumstances of use and equipment design must also dictate the frequency
of cleaning the display areas. Weekly washing down of the storage
compartment is also recommended, especially for equipment subject to
drippage of milk or other liquids, or the collection of vegetable, meat,
crumbs, etc. or other debris or litter. Daily cleaning of the external areas
surrounding the storage or display compartments with detergent and water
will keep the equipment presentable and prevent grime buildup.
1.2 Load levels as defined by Hussmann must be observed.
1.3 The best preservation is achieved by following these rules:
a) Buy quality products.
b) Receive perishables from transit equipment at the ideal temperature
for the particular product.
c) Expedite perishables to the store’s storage equipment to avoid
unnecessary warm-up and prolonged temperature recovery. Food
store refrigerators are not food chillers nor can they reclaim quality
lost through previous mishandling.
d) Care must be taken when cross merchandising products to ensure
that potentially hazardous vegetable products are not placed in non
refrigerated areas.
e) Display and storage equipment doors should be kept closed during
periods of inactivity.

towel.
10. When “freshening” foods such as macaroni and cheese with
added water, heat the water in a clean container until it is
10° to 20°F above the desired holding temperature of the
food. This will keep the food at a safe serving temperature.
Depending on the amount of water, the temperature can drop
10° to 20° in as little as five minutes.
11. When transferring hot foods in the heated merchandiser to
clean pans, preheat the clean pan. Transferring hot foods to
room temperature pans can cause the temperature of the food
to drop 20° or more thus causing food to be at an unsafe
serving temperature.
12. Clean spills as they happen simply by wiping with a cloth. Be
sure to use a dry cloth on very hot surfaces to prevent steam
burns.
13. Turn the equipment off and allow to cool before cleaning.
14. To remove “baked-on” splatter from Stainless Steel, the
following may be used
Grade F Italian Pumice Scour or rub with a damp cloth
Liquid Nusteel
Scour with a small amount of a dry
cloth
Paste NuSteel
Household Cleaners
Rub with a damp cloth
