NEC, Federal, State, and Local
Plumbing and Construction
Code having jurisdiction.
Important Information
The VGM / VGD service cases are easy to work, attractive merchandising display cases capable of maintaining
superb product quality, with the installation of the
proper controlling devices. These should be set according
to Hussmann’s specifications and combined with a
properly maintained humidity system. Incorrect settings
and failure to maintain the humidity system will result in
short product life from dehydration, shrinkage and
discoloration. Below are a few guidelines to ensure
optimum performance and product life.
• Review the Case Specification in this book to verify
thermostat setting. Do not set temperature too cold,
as this causes product dehydration.
•Temperatures should be achieved by a t-stat and suc-
Rev. 0505
tion solenoid at each case. Do not use EPR valves, liquid line solenoids or electronic control devices of any
kind. These controls allow temperature swings
causing product dehydration and excessive
energy consumption.
• Defrost cycles should be set according to the Case
Specifications in this book.
• 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.
• Maintain sanitary conditions throughout the deli
holding, prep and working areas.
• Do not display product directly within the air discharge.

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, 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.
UNCRATING 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.
DANGER!
IMPORTANT: READ BEFORE RAISING GLASS!
HEX SCREWS ALONG CLAMSHELL
MAY HAVE LOOSENED DURING
SHIPPING!! RETIGHTEN ALL
CLAMSHELL SCREWS BEFORE
OPENING GLASS!
RETIGHTEN GLASS AFTER CASE IS
BROUGHT TO OPERATING
TEMPERATURE FOR THE FIRST
TIME!
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".
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, 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, GLASS ALIGNMENT, AND OPERATION OF THE
HINGES SUPPORTING THE GLASS. LEVELING THE
CASE CORRECTLY WILL SOLVE MOST HINGE OPERATION PROBLEMS.
NOTE: A. To avoid removing concrete flooring, begin 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 carpenter’s 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
back and side to side on inside bulkheads at joint.
8. Attach sections together via a 3 bolts located in the
base of the case. Secure the overhead structure by
bolting the rear mullions tegether.
Do not use bolts
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. VERY IMPORTANT! Apply liberal amounts of
black silicone to area under interior lower legs and
fill all voids down to bulkhead.
11. 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.

Plumbing
It is the contractor's
responsibility to install
case(s) according to local
construction and health
codes.
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 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.

Humidification
HUMIDIFICATION SYSTEM (WHERE APPLICABLE)
One contributor to spoilage of fresh meat and deli
products that are displayed in refrigerated service type
merchandisers is dehydration, which causes the product
to shrink and dry out. The humidification system is
designed to maintain a high relative humidity (RH) inside
Hussmann’s refrigerated service type merchandisers—
and minimize dehydration.
The humidification system is located on the back wall
under the rear discharge air grill of the VGM / VGD
FAMILY. It is imperative that the system be maintained as
per the instructions in the maintenance section. Buildup
of residue will cause leakage and/or unfavorable water
conditions. If the area’s water is hard, check the system
more frequently than under good water conditions.
INSTRUCTIONS
Tu rn on water and fans, and check for leaks. This system
has been tested at the factory, and should not require
any additional adjustments.
The system is constructed almost entirely of PVC pipe,
and user air that is sub-cooled 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 612 months, depending on the kind of water found
in your area.
3. Flush the header every 6 months, by loosening the

IMPORTANT INFORMATION
The VGM / VGD case line is easy to work, and capable of
maintaining superb product quality with the installation
of the proper controlling devices. These should be set
according to the Hussmann’s specifications, and a properly maintained humidity system. 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 30º-32ºF discharge temperature, to maintain a temperature for Deli, Meat,
and Fish at 36ºF. 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.
• Clean humidity system a minimum of every 90 days for
proper system operation.
• Work and rotate product - not to exceed a 4-hour
period.
• At night, turn off case lights, and cover product with
moistened cheese cloth or fabric towels.
• Keep meat prep room refrigerated at 55ºF.
• Meat Bloom Box (if applicable ) should be at 30ºF.

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.
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
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.
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. For all multiplexing, defrost should be time
terminated. Defrost times 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.
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
controller Hussmanns 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
8
THERMOSTATIC EXPANSION VALVE LOCATION
This device is located on the same side as the refrigeration stub. An ALCO expansion valve model is furnished
as standard equipment, unless otherwise specified by
customer.
EXPANSION VALVE ADJUSTMENT
There is one (1) valve on the right side of each coil.
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.
5. The difference is superheat.
6. Set the superheat for 5°F - 7°F.
T-STAT LOCATION
T-Stats are located within the electrical raceway. Refer to

The only difference between a remote case and a selfcontained case is the addition of a condensing unit.
SELF CONTAINED START-UP
Self contained cases are totally ready to run once power
is supplied. All controls are set and units charged with
refrigerant.
DEFROST SET-UP
Defrost times vary according to case model - refer to
Case specification section in the back of the book for
proper duration and frequency. Self contained cases have
individual defrost time clocks. When power has been
applied, set the time clock to the proper duration and
frequency.
The time clock is located behind the front panel under
the case. Turn the clock dial counterclockwise until the
pointer is directed to the current time of day.
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 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 cases, completely cover the product each
night with a clean damp cloth or butcher paper
(never use plastic, as it does not allow appearance and
significantly shortening product shelf life.
Rev. 0505
10. 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. For temperature settings, please see the Case
Specifications section in this book.
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 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
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
9
VGM, VGD-0505
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.
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 first.
CLEANING
PRECAUTIONS
WHEN CLEANING:
Never Use a Cleaning or Sanitizing
Solution that has an OIL BASE
(these will dissolve the butyl
sealants) or AMMONIA BASE (this
will corrode the copper components
of the case)
TO PRESERVE THE ATTRACTIVE FINISH:
Do Use Water and a Mild Detergent for
the Exterior Only!
Do Not Use Abrasives or Steel Wool
Scouring Pads (these will mar the finish)
PLEXIGLASS & ACRYLIC CARE
Improper cleaning not only accelerates the cleaning cycle
but also degrades the quality of this surface. Normal daily
buffing motions can generated static cling attracting dust
to the surface. Incorrect cleaning agents or cleaning
cloths can cause micro scratching of the surface, causing
the plastic to haze over time.
CLEANING
Hussmann recommends using a clean damp chamois, or
a paper towel marked as dust and abrasive free with
®
210
Plastic Cleaner and Polish available by calling
Sumner Labs at 1-800-542-8656. Hard, rough cloths or
paper towels will scratch the acrylic and should not be
used.
ANTISTATIC COATINGS
The 210® has proven to be very effective in not only
cleaning and polishing the Plexiglass surface, but also
providing anti-static and anti-fog capabilities. This product
also seals pores and provides a protective coating.
NON-GLARE GLASS
The high optical clarity of this glass is possible due to
special coatings on the glass surface itself. To preserve
this coating and the optical clarity, keep th glass clean.
Windex® or Glass Plus® are the only soluitons recommended to be used to clean the non-glare glass. The
damage to the glass from improper, cautic 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 tha tthe glass be fully opened and
covered to prevent to prevent solutions from
plasihgn onto the glass and ruining the coating on the
inside.

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".

Maintenance (cont.)
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)

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.

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 dry-bulb 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.

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
APPENDIX C. – FIELD RECOMMENDATIONS
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
21
VGM, VGD-0505
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 ther-
mometer 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?
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 /airconditioning 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?
10. Is the store ambient over 75°F, 55% RH as set forth in
ASHRAE Standard 72 and ASHRAE Standard 117?
11. Are the shelf positions, number, and size other than
recommended by Hussmann?
12. Is there an improper application or control system?
13. Is the evaporator fan motor/blade inoperative?
14. Is the defrost time excessive?
22
15. Is the defrost termination, thermostat (if used) set too
high?
16. Are the refrigerant controls incorrectly adjusted?
17. Is the air entering the condenser above design conditions? Are the condenser fins clear of dirt, dust, etc.?
18. Is there a shortage of refrigerant?
19. 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 Hussmann equipment recommendations? Is the refrigerator charged with the proper refrigerant and lubricant?
Does the system use the recommended compressor?
APPENDIX D. – RECOMMENDATIONS TO
USER -
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 dripping 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 equip-
ment 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
