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% rela-
tive 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, prepa-
ration 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 sup-
port excessive external loading. Do not walk on their
tops;This could cause serious personal injury and dam-
age to the fixture.
Retighten glass along clamshell
after leveling and first time case
is brought to full operating
temperature!
GLASS BREAKAGE
MAY OCCUR!
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.
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.
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.
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!
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
Installation

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 refrigera-
tion, electrical, and wasted piping work completed, install
the splashguards.Fasten along the top edge,or center,with
#10 X 3/8" sheet metal screws.
DONOT SEAL JOINT T RIM T OFLOOR!
Installing R3HTO, R3HATO
All cases were tested at a level state before shipping.When
joining, use a carpenters level and shim enclosing or sup-
porting cabinet accordingly.
1. Make sure the cabinet you are installing the
R3HATO on is level.
2. Wire unit according to local codes.
Plumbing
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 sup-
plied with each fixture.The 3 P-traps must be installed to
prevent air leakage and insect entrance into the fixture.
NOTE: PVC-DWV solvent cement is recommended.
Follow the manufacturer’s instructions.
INSTALLING CONDENSATE DRAIN
Poorly or improperly installed condensate drains can se-
riously 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:
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 plumb-
ing 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 main-
tain 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 asArmstrong’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.
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 wa-
ter line before hooking it up to the filter to prevent block-
ing the filter.
Refrigeration - R3H, R3HA with refrigerated front
REFRIGERANT TYPE
The standard refrigerant will be R-22 unless otherwise
specified on the customer order. Check the serial plate
on the case for information.
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

IGFP-R3H, R3HTO, R3HA, R3Combo-0208

suction lines to prevent condensation drippage.
REFRIGERATION LINES
LIQUID SUCTION
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.
Refrigerant lines should be sized as shown on the refrig-
eration legend furnished by the store.
Install P-traps (oil traps) at the base of all suction line ver-
tical 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.
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 tempera-
tures.Product temperature should be measured first thing
in the morning, after having been refrigerated overnight.
Defrost times should be as follows: OFF CYCLE - Con-
sult the Case Specification Section of this guide for de-
frost settings. The number of defrosts per day and the
duration of the defrost cycle may be adjusted to meet
conditions present at your location.
ACCESS TO TX VALVES & DRAIN LINES
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).
ELECTRONIC EXPANSION VALVE (OPTIONAL)
A wide variety of electronic expansion valves and case
controllers can be utilized. Please refer to EEV and con-
troller manufacturers information sheet. Sensors for elec-
tronic 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 in-
stalled 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.
THERMOSTATIC EXPANSION VALVE LOCATION
This device is located on the same side as the refrigera-
tion stub. A Sporlan balanced port expansion valve model
is furnished as standard equipment,unless otherwise speci-
fied by customer.
EXPANSION VALVE ADJUSTMENT
Expansion valves must be adjusted to fully feed the evapo-
rator. 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 operat-
ing temperature.
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.
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.
Service Case Temperature Control
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,

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.
ELECTRICAL SERVICE RECEPTACLES
(When Applicable)
The receptacles located on the exterior of the merchan-
diser are intended for scales and lighted displays.They
are not intended nor suitable for large motors or other
external appliances.
BEFORE
SERVICING
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.
FIELD WIRING & SERIAL PLATE AMPERAGE
FieldWiring 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 refrig-
eration 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.
Windex®or Glass Plus®are the only solutions recom-
mended to be used to clean the non-glare glass. The dam-
age to the glass from improper, caustic solutions is irrepa-
rable.
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 recom-
mend 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.
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 tow-
els will scratch the acrylic and should not be used.
ANTISTATIC COATINGS
The 210®has proven to be very effective in not only clean-
ing 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
REPLACING FLUORESCENT LAMPS
Fluorescent lamps are furnished with a shatterproof pro-
tective 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 merchandis-
ers were designed for use in stores were tempera-
ture & humidity does not exceed 75°F and 55% H.
User Information
Stocking Refrigerated Sections
Improper temperature and lighting will cause serious prod-
uct loss. Discoloration, dehydration and spoilage can be
controlled with proper use of the equipment and handling
of product. Product temperature should always be main-
tained at a constant and proper temperature.This means
that from the time the product is received, through stor-
age, preparation and display,the temperature of the prod-
uct 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 pro-
tection required always:
1. Minimize processing time to avoid damaging tem-
perature 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 dete-
riorate.
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 mer-
chandiser 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 dis-
charge and return air flue must be unob-
structed at all times to provide proper refrig-
eration.
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 maxi-
mum 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.
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 ap-
proximately 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,

Rev.0208
9
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 qual-
ity 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 require-
ments.
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, tex-
ture 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.
Food temperatures can be accurately deter-
mined only through the use of food ther-
mometers!
IMPORTANT OPERATION TIPS:
* 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,decreas-
ing visibility.
* Make sure all pans are in the well 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". 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 mainte-
nance.
* 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

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 shouldALWAYS 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 FoodTemperatures.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.
