LOCATION
The refrigerated merchandisers have been designed for use only in air conditioned stores where temperatur e and humidity are maintained at or below 75°F and 55% rela­tive humidity . DO NO T 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

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 COR­RECTL Y 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 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 wher e cases are to be set. Determine the highest point of the floor; cases will be set off this point.
2. Set first case, and adjust legs over the highest part of the floor so that case is level. Prevent damage – case must be raised under leg or by use of 2x6 or 2x4 leg brace. Remove side and back leg braces after case is set.
3. Set second case as close as possible to the first case, and level case to the first using the instructions in step one.
4. Apply masking tape 1/8" in from end of case on inside and outside rear mullion on both cases to be joined.
5. Apply liberal bead of case joint sealant (butyl) to dotted area shown in (Fig.2, #1) of first case. Apply heavy amount to cov er entire shaded area.
DO NO T USE PERMAGUM!
6. Slide second case up to first case snugly . Then lev el second case to the first case so glass front, bumper and top are flush.
7. Apply bead of silicone to side of either half of case (if case is built in two pieces). Also apply silicone to seam between overhead light tubes.
8. Slide second half up to first case snugly . To compress silicone at joint, use two J urgenson wood clamps to pull the inside of the bulkheads together . Make sure case is level from fr ont to back and side to side at joint. DO NO T USE BOLTS T O DRA W CASES UP TIGHT! DAMA GE MAY OCCUR!6. Make sur e cases are tight and bolted together in all locations (see diagram next page). Remov e clamps. Cleanup excess silicone.
9. There ma y be an interlock system built into the tower , depending on the height of it. Joining in volves a number of bolts, again dependent on the height.
10.Attach joint trim pieces, that will hide the loose joint where the case halves come together.
11.Connect case to field electrical, refrigeration, and pipe to floor sink.
12. Install body cov ers.
13. Attach cart bumper, if applicable.

SPLASH GUARD

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 3/3" sheet metal screws.
DO NOT SEAL JOINT TRIM TO FLOOR!
It is the contractor’s responsibility to install
case(s) according to local construction and
health 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. 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 manufacturer’s instructions.
ACCESS PANELS
All electrical and drain access panels are clearly labeled on the deck of the produce stand. The access for con­densing units (in the self contained units) is located on the side of the stand, at the end. Ends of stand are fitted for removal, if condensing unit has to be taken out.
INSTALLING CONDENSATE DRAIN
Poorly or improperly installed condensate drains can se­riously interfere with the operation of this refrigerator, and result in costly maintenance and pr oduct 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. Nev er use two water seals in series in any
IGIP-DBP, DBRP 01,03-0210
one line. Double P-traps in series will cause a lock and prevent draining.
3. Always pr ovide as much down hill slope (“fall”) as possible; 1/8" per foot is the pr eferred 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 pro vide the “fall” necessary for good drainage.
5. Provide a suitable air break betw een the flood rim of the floor drain and outlet of condensate drain. 1" is ideal.
6. Prevent condensate drains fr om 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 ar e located in dead air
spaces (between refrigerators or betw een a refrigerator and a wall), provide means to pr event freezing. The water seal should be insulated to prevent condensation.
HOSE REEL
If an optional hose reel is ordered, it will be installed at the factory. The water supply valve is located next to the access panel. Connect the water supply to the valve.
SPRAY HOSE
If an optional quick-disconnect spray hose is ordered, a pressure regulating valve should be installed. If the water pressure exceeds 45 PSI, the valve should be set for 30 to 35 PSI outlet pressure.

Refrigeration

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 suction lines to prevent condensation drippage.
ACCESS PANELS
All electrical and drain access panels are clearly labeled on the deck of the produce stand. The access for con­densing units (in the self contained units) is located on the side of the stand, at the end. Ends of stand are fitted for removal, if condensing unit has to be taken out.
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 y our merchandiser . Maintain these parameters to achieve near constant product tempera­tures. Pr oduct temperature should be measured first thing in the morning, after having been refrigerated overnight. For all multiplexing, defrost should be time terminated. Loadmaster valves are not recommended. 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 ma y be adjusted
to meet conditions present at your location.
ACCESS TO TX VALVES & DRAIN LINES
MECHANICAL - Remove product fr om end of case. Remove product racks. Remo ve 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 manufacturers inf ormation 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 racewa y or under the case
THERMOSTATIC EXPANSION VALVE LOCATION
This device is located on the same side as the refrigera­tion stub. A balanced port expansion valve model is fur­nished as standard equipment, unless otherwise specified by customer.
EXP ANSION V AL VE ADJUSTMENT
Expansion valves must be adjusted to fully feed the e vapo­rator. 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.
MEASURING THE OPERATING SUPERHEAT
1. Determine the suction pressure with an accurate pressure gauge at the e vaporator outlet.
2. From a refrigerant pr essure 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 fr om the temperature measured in step No. 3.
3. The difference is superheat.
5. Set the superheat for 5°F - 7°F.

T-STAT LOCATION

T-Stats are located under access panels on the end of the case.

STOCKING

Improper temperature and lighting will cause serious pr od­uct 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 displa y, the temperature of the pr od­uct 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 a void damaging tem­perature rise to the product. Product should be at proper temperature.
2. K eep the air in and around the case area fr ee of foreign gasses and fumes or food will rapidly dete­riorate.
3. Maintain the display mer chandisers temperature controls as outlined in the refrigerator section of this manual.
4. Do not place any product into these r efrigerators until all controls ha ve 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, nev er allow the product to extend beyond the recommended load limit. Air dis-
charge and return air flue must be unob­structed at all times to pro vide proper refrig­eration.
6. There are v ents located at the base of the front of the glass, just abov e the front rail. These vents supply a continuous, gentle flow of air acr oss the front glass which inhibits condensation. Do not place any
signs or other restrictive objects on the fr ont of the refrigerator that will block these v ents.
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 . and V .H.O.), will shorten the shelf life of the product.
8. Cold coils remove heat and moistur e from the case and deposit this as frost onto the coil. Thus, a defrost is requir ed. 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 deh ydration. See Case Specs for Pr oper
Temperature: Settings.

CASE CLEANING

Long life and satisfactory performance of any equipment are dependent upon the care giv en 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, how ever , these solutions should always be used accor ding to the manufacturer’ s directions. It is essential to establish and regulate cleaning procedur es. This will minimize bacteria causing discoloration which leads to degraded product appearance and significantly shortening product shelf life.
Soap and hot water are not enough to kill this bacteria. A sanitizing solution must be included with each cleaning pro­cess to eliminate this bacteria.
1. Scrub thoroughly , cleaning all surfaces, with soap and hot water .
2. Rinse with hot water , but do not flood.
3. Apply the sanitizing solution according to the manufacturer’ s dir ections.
4. Rinse thoroughly .
5. Dry completely before resuming operation.
CLEANING PRECAUTIONS
WHEN CLEANING:
DO NOT USE HIGH PRESSURE WATER HOSES
• DO NOT INTRODUCE WATER FASTER THAN WASTE OUTLET CAN DRAIN
• NEVER ON A SELF CONTAINED UNIT WITH AN EVAPORATOR FAN
• NEVER USE A CLEANING OR SANITIZING SOLUTION THAT HAS AN OIL BASE (these will dissolve the butyl sealants) or an 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)

Appendices
APPENDIX A. – Temperature Guidelines Refrigerated
The refrigerators should be operated according to the manufacturer’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.

tions and recommendations provided by the manufacturer for the installation of each individual type refrigerator.
1.2 Refrigeration piping should be sized according to the equipment manufacturer’s recommendations and installed in accordance with normal refrigeration practices. Refrigeration piping should be insulated according to the manufacturer’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 manufacturer’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 the manufacturer.
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 instruc-
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 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
15
IGIP-DBP, DBRP 01,03-0210
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?
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 the manufacturer?
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 the equipment manufacturer? 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 The manufacturer 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 the manufacturer 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.
16
Rev.0210
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 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 the manufacturer’s recom­mendations.
j) See that all storage and refrigeration equipment is kept in
proper working order by routine maintenance.
