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,
ovens, 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.

TIGHTEN GLASS SCREWS

Tighten screws along clamshell located on the underside
of glass before placing unit into operation.
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.
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.

UNCRATING THE STAND

Place the fixture as close to its permanent position as
possible. Keep in place, attached case until ready to set/

adjustable legs to allow for leveling.
NOTE: The mock pedestal option supplies panels that
clamp on to adjustable legs.
2. Set first case over the highest part of the floor and
adjust legs so that case is level. Remove side and back
leg braces after case is set and joined.
3. Set second case within one foot (1’) of the first case,
and remove end shipping support. Keep the supports
along the length of the case and far end of case. 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 first
case. Sealant area is shown using a dotted line in
illustration in Step 8. Apply heavy amount to cover
entire shaded area.
DO NOT USE PERMAGUM

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,
glass alignment, and operation of the hinges
supporting the glass. Leveling the case
correctly will solve all hinge operation and
glass alignment problems.
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.

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 adjust legs
accordingly. The legs on the ASCS are adjustable and do
not require shims. Simply screw the leg up or down to
adjust height.
1. Using case blueprints, measure off and mark on the
floor the exact dimensions of where the cases will sit.
Snap chalk line for front and back positions of base rail
or pedestal. Mark the location of each joint front and
back. Find the highest point throughout the lineup.
FLOORS ARE NORMALLY NOT LEVEL! Determine
the highest point of the floor; cases will be set off this
point. All cases in the entire lineup must be brought
up to the highest level of the case sitting at the highest
point in the lineup. This may be done a few different
ways. 1) Walk the floor looking for any mounds or dips.
2) Use a string level. 3) Use a transit. If a wedge is used
in the middle of a lineup, the wedge must be set on the
highest point on the floor FIRST, with the rest if the
lineup being leveled from it. The ASCS case has

(apply additional silicone if necessary). Remove tape
applied on line #4.
11. Remove front, back and end shipping braces.
INSIDE REFRIGERATED WEDGES

Line up taper pins with holes on adjoining case. Turn
camlock to lock in. Two camlocks are located at the rear
of the case behind the air discharge and behind the lower
electrical raceway access panel. Bolt the wedge into the
adjoining case in the front. If the adjoining case is
refrigerated, the bolt is located under the pans in the front.
When the adjoining case is a hot case, the cases are bolted
together by mans of a bracket located behind the front
panel. Remove the front panel by lifting it up and out..

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.

two water seals in series in any one line. Double Ptraps 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.

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.
A 1-1/2" P-trap and threaded adapter are supplied with
each fixture. The P-trap must be installed to prevent air
leakage and insect entrance into the fixture.
NOTE: PVC-DWV solvent cement is recommended.
Follow the Hussmann’s instructions.

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:
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

Humidity System
GENERAL DESCRIPTION

One contributor to the spoilage of fresh meats is
dehydration, which causes loss in weight and volume
(shrinkage) and product discoloration.As the refrigeration
system removes heat from the case, it also removes critical
moisture from the air, and any unwrapped products in the
case. The Humidity System replaces the moisture in the
air, in order to compensate for the moisture taken by the
refrigeration system, and disposed of down the drain line.
The system is built into the discharge plenum, and mixes
moisture laden air with refrigerated air before the air is
passed through - and around the product.
The system is constructed almost entirely of PVC pipe,
and uses air that is subcooled to approximately the same
temperature as the case. The sub-cooling of air inhibits
the formation of growth found to be a problem in other
humidification systems. Maintenance is almost unnecessary
if you follow a few simple rules:
1. Keep the case clean.
2.Keep the water filter clean, and change it every six
to twelve months or sooner, depending on the kind of
water found in your area.
3. Flush the header every six (6) months, by loosening
the connecting “L”, then removing it from the case, and
flushing with a hose.
**IMPORTANT INFORMATION**
The ASCS is capable of maintaining superb product quality
with the installation of the proper controlling devices.These
devices should be set according to the Hussmann’s
specifications. The humidity system should be properly
maintained. Incorrect settings and failure to maintain the
humidity system will result in short product life. Below
are a few guidelines for optimum performance and product
life:
• Set thermostat to cut in at the discharge temperature
designated in the case specifications section of the
appropriate installation guide or spec. sheet. Maintain
the recommended product temperature for Deli,
Meat, and Fish. DO NOT set temperature too cold, as
this causes product dehydration.
• Temperatures should be achieved by means of a T-Stat
and Suction Solenoid at each case. DO NOT use EPR
valves, Liquid Line Solenoids, or electronic control
devices of any kind.These controls allow temperature
swings that cause dehydration and excessive energy
consumption.
• Set defrost cycles as listed in the Case Specifications
Data for your particular case. The number of defrosts
per day should never change. The duration of the

defrost cycle may be adjusted to meet conditions
present at your location.
Clean humidity system a minimum of every 90 days for
proper system operation.
Work and rotate product - not to exceed a four (4)
hour period.
At night, turn off case lights, and cover unwrapped
product with moistened cheesecloth or fabric towels.
Keep meat holding box at 32°F.
Keep meat prep room refrigerated at 55°F.
Meat Bloom Box (if applicable) should be at 36°F.
Meat must enter the case at 40°F or below. Product
deteriorates rapidly above 40°F.
Clean, sanitary conditions are required throughout the
meat holding, prep, and work areas.
Do not display product directly within the air
discharge
Turn and rotate meat.The blood works down through
the meat over time, which causes the top surface to
discolor and dehydrate.Turn meat 3-4 times per day.
It is not required to remove product from case
overnight.Turn off case lights, and cover product with
moistened cheesecloth or fabric towel.This helps slow
down product dehydration, by taking moisture from
the cloth and not the product. This is an old method
used by meat shops for many years, as it extends
product life.
Cold coils remove heat and moisture from the case
and deposit this as frost onto the coil.Thus a defrost
is required to remove this frost. Our humidity system
induces moisture into the case, and helps slow down
the dehydration process. The only other moisture in
the case is that which is in the product. A single level
of meat will dry out faster than a fully loaded case with
3-4 levels of meat.
The colder the case, the faster the product loses its
moisture and shelf life. It is very important to maintain
a constant, even, correct, product temperature.

HUMIDIFICATION SYSTEM HOOKUPS

Remove the raceway panel on the lower back of the case.
The pre-piped water shut-off valve and the water filter
are located on the left hand side of the case. The water
line (which is a 1/4" OD copper fitting) can be connected
to the ball shut-off valve, by means of a compression fitting
(supplied).The line should be one size larger than the supply
line. The line can then be run from one case to another
from within the raceway(s) using Tee connectors. Before
connecting the water to the humidity system, it is best to

3. Check strainer at entrance to nozzle.
Reinsert the header into the 90° “L”, making sure that the
nozzle is in the center of the pipe when totally inserted,
and the holes in the header are facing the front of the case
at a level angle.
The discharge tube can easily be pulled to service.

purge the line to flush any debris that may clog the water
filter. If the water line requires purging after the cases are
hooked together, it is not necessary to check each one.
Simply shut ball valves to each humidity system, remove
the water line from the last case in the flow, and purge. By
doing this as a precautionary measure, you may avoid
problems and repeat servicing.

MAINTENANCE

•
START-UP

Turn on the fan circuit. Check to see if the fan for the
humidity system is running. Remove the right hand bottom
pan (when facing the front of the case), then the TXV cover.
The fan is located up against the right hand side of the
case, as viewed from the front, under the fan plenum (see
diagram). View the blade, and make sure the fan rotation
agrees with the air flow arrows. Turn on the water, by
turning the ball valve in the direction of the flow (OFF is
at 90° to the direction of flow).
After a few minutes, check the spray header by sliding the
honeycomb to the left to expose the discharge tube located
on the right hand side of the case (when viewed from the
rear), by lifting the 4'-0" section of honeycomb with both
ends, until the bottom clears. Pull up and set aside. The
spray header will be exposed. Grasp the header and pull it
loose from the 90° “L” until you see the misting nozzle,
which should be spraying. If not, check the following:
1. Make sure the water is feeding the nozzle.
2. Remove the nozzle, and purge the water.

Clean humidity system a minimum of every 90 days for
proper system operation.

REFRIGERANT TYPE

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.

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
suction lines to prevent condensation drippage.

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 first be
measured in the morning, after having been refrigerated
overnight. For all multiplexing, defrost should be time
terminated. Defrost length and frequency should as
directed in the Case Specifications section of this guide.
The number of defrosts per day should never change.The
duration of the defrost cycle may be adjusted to meet
conditions present at your location.

Finishing Touches

JOINT TRIM
After cases have been leveled and joined, and refrigeration,
electrical, and waste piping work completed, install the
splashguards. Fasten along the top edge, or center, with
#10 X 3/3" sheet metal screws.

3. Bend the bumper backwards to open and guide it
forward onto the bumper channel.
4. An inside bumper miter must be cut on wedges.
5. Loose ends on miters must be anchored with screws
on the bottom edge.
6. The top and bottom edges of the bumper must be
firmly seated into the retainer by applying with a
rubber mallet (not by hand).
7. The bumper should be struck by the mallet at a slight
angle that forces the bumper back into itself to
prevent stretching.The installation can be made easier
by applying a paraffin block to the retainer grooves.
INSTALLING SPLASHGUARD

After merchandisers have been leveled and joined, and all
drip piping, electrical and refrigeration work has been
completed, install the splashguards. Splashguards 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 allow
access to components behind it.
1. Remove all dirt, wax, debris, etc. from the area of the
splashguard to ensure a secure adhesion.
2. Apply a good contact cement to the trim, allowing a
proper dry time.
3. Install trim to the splashguard so that it is flush with
the floor.

User Information

STOCKING
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 six (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. There are vents located at the base of the front of the
glass, just above the front rail. These vents supply a
continuous, gentle flow of air across the front glass
which inhibits condensation. Do not place any
signs or other restrictive objects on the front of
the refrigerator that will block these vents.
7. Keep the service doors closed (when applicable).
Refrigeration performance will be seriously affected
if left open for a prolonged period of time.
8. 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. and V.H.O.), will
shorten the shelf life of the product.
9. In the Deli, Meat and Fish cases, completely cover the
product each night with a clean damp cloth or butcher
paper (never use plastic, as it does not allow for
proper circulation). Make sure the cloth or paper is in
direct contact with the product.

10. Turn and rotate the meat fairly often. The blood which
gives the pink color works its way downward with
time.
11. Cold coils remove heat and moisture from the case
and deposit this as frost onto the coil. Thus, a defrost
is required. Our humidity system induces moisture
into the case and helps slow down the dehydration
process. The only other moisture within the case is
that in the product itself. A single level of meat will dry
out faster than a fully loaded case of 3–4 levels of meat.
IMPORTANT STEPS

1. Do not set temperature too cold, as this causes
product dehydration. Product Temperature: 33°–
35°! Set thermostat to cut in at 28° discharge air. Meat
holding box: 32°. Meat prep room: 55°. Meat bloom
box: 36°. Process the meat to enter case at 40° or
below. Product deterioration is very rapid above 40°.
2. Temperature control should be by means of a T-Stat
and Suction Stop Solenoid at each case. DO NOT use
EPR valves, Liquid line solenoids or electronic control
devices of any kind, as these allow temperature swings
causing dehydration and excessive energy
consumption.
3. Product should be worked and rotated on a regular
basis, not to exceed a 4 hour period.
4. At night, turn off case lights and cover the product
with a damp (not wet) cloth similar to cheese cloth
(etc.).This should be washed out in the morning and
kept in a walk-in box during the day—so that it is cool
and moist when covering the product.
5. Discharge air temperature should be approximately
26°F, with between 150-200 FPM air velocity. Do not
display product directly within the air discharge.
6. Clean humidity system a minimum of every 90 days for
proper system operation.
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
refrigerator should be thoroughly cleaned frequently. SHUT
OFF FAN DURING CLEANING PROCESS. It can be
unplugged within the case, or shut off entire case at the
source. The interior bottom may be cleaned with any
domestic soap or detergent based cleaners. Sanitizing
solutions will not harm the interior bottom, however, these
solutions should always be used according to the
Hussmann’s directions. It is essential to establish and
regulate cleaning procedures. This will minimize bacteria
causing discoloration which leads to degraded product

Rev.0303

and the optical clarity, keep the glass clean.
Windex ® or Glass Plus ® are the only solutions
recommended for use in cleaning 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.

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.
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 Hussmann’s
directions.
4. Rinse thoroughly.
5. Dry completely before resuming operation.

PLEXIGLASS and 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 GLASS AND 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 first.

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.

CLEANING PRECAUTIONS

ANTISTATIC COATINGS

WHEN CLEANING:

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.

Do Not Use High Pressure Hoses
Do Not Introduce Water Faster than Waste
Outlet can Drain
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)

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

Maintenance (continued)

LIFT UP GLASS
IMPORTANT!
READ BEFORE RAISING FRONT GLASS :
HEX SCREWS ALONG CLAMSHELL MAY HAVE
LOOSENED DURING SHIPPING!! RETIGHTEN ALL
CLAMSHELL SCREWS BEFORE OPENING GLASS!

Glass is heavy and
can cause bodily
damage. Check
support cylinders
for periodic
maintenance

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.
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.
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. (1)(3)

Once cylinders are
removed, front glass
will have NO support to
maintain a raised
position. Support the
front glass at all times
until cylinder is
replaced or the glass
is lowered.

RE-ADJUSTMENT After Initial STARTUP
In addition to verifying that the Allen screws on the lift-up
glass are tightened when the case is delivered, recheck
the Allen screws on the glass ONCE THE CASE IS
IN FULL OPERATION AND BROUGHT TO
TEMPERATURE.
Temperature changes can affect the size and shape of the
materials involved, and cas cause changes in the secure fit
of the glass and the clamp.
Important Glass Notifications

CAUTION
Cylinders are a wear item.
They are designed:
•To support the glass
when fully open
• to allow the glass to
close slowly

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 dry-bulb
and wet-bulb temperatures to ASCSertain 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.

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.

Recommendations for field evaluating the performance of retail
food refrigerators and hot cases

1.0 The most consistent indicator of display refrigerator performance is
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

Reach-In

II. Closed Display Styles

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
35

IGSV-ASCS-0303

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:

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
equipment? Is the refrigerator charged with the
proper refrigerant and lubricant? Does the system use
the recommended compressor?
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 warm-up, 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.
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

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?
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?
9.Are display signs blocking or diverting airflow?
10.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.?

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.
