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.

Installation

Uncrating the Stand

Place the xture 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 xture 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 xture.

Installation (Cont'd)

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 ooring, begin lineup

leveling from the highest point of the store oor.

B. When wedges are involved in a lineup, set them rst.

All cases were leveled and joined prior to shipment to

insure the closest possible t when cases are joined in the eld. 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 oor where cases are to be set. Determine the highest point of the oor; cases will

be set off this point.

2. Set rst case, and adjust legs over the highest part of the oor 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

rst case, and level case to the rst 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 gure) rst case. Apply heavy

amount to cover entire shaded area.

DO NOT USE PERMAGUM!

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 rst case snugly. To

compress silicone at joint, use two Jurgenson wood clamps to pull the inside of the bulkheads together. Make sure case is level from front to back and side to side at joint. DO NOT USE BOLTS TO DRAW CASES UP TIGHT! DAMAGE MAY OCCUR! Make sure cases are tight and bolted together in all locations (see diagram next page). Remove clamps. Cleanup excess silicone.

9. There may be an interlock system built into the tower, depending on the height of it. Joining involves 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 eld electrical, refrigeration, and pipe to oor sink.

12. Install body covers.

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!

6. Slide second case up to rst case snugly. Then level second case to the rst case so glass front, bumper and top are ush.

Plumbing

IGIP-DBP, DBRP 01, 03-0508

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 xture.

A 1-1/2” P-TRAP and threaded adapter are supplied with

each xture. The P-TRAP must be installed to prevent air leakage and insect entrance into the xture.

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 tted 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 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 oor 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.

Refrigeration

Refrigerant Type

The standard refrigerant will be R-22 unless otherwise

specied on the customer order. Check the serial plate on

the case for information.

Piping

The refrigerant line outlets are located under the case.

Locate rst 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 tted 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.

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 ood rim of the oor 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 non absorbent insulation

material such as Armstrong’s Armaex.

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.

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.

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 DBP, DBRP 01, 03 technical data sheet for the appropriate settings for your merchandiser. Maintain these parameters to achieve near constant product temperatures.

Product temperature should be measured rst 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 be as directed in the DBP, DBRP 01, 03 technical data sheet. 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.

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 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.

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 specied by

customer.

Electrical

Expansion Valve Adjustment

Expansion valves must be adjusted to fully feed the evaporator. Before attempting any adjustments, make sure the evaporator is either clear or very lightly covered

with frost, and that the xture 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 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 under access panels on the end of the case.

Field Wiring and Serial Plate Amperage

Field Wiring must be sized for component amperes printed on the serial plate. Actual ampere draw may be less than

specied. Field wiring from the refrigeration control panel to

the merchandisers is required for refrigeration thermostats. Case amperes are listed on the wiring diagram, but always check the serial plate.

Ballast Location

Ballasts are located within the access panel that runs the length of the rear of the case. Refer to diagram on page 5.

Wiring and Serial Plate Amperage

Field Wiring must be sized for component amperes stamped on the serial plate. Actual ampere draw may be less than

specied. Field wiring from the refrigeration control panel to

the merchandisers is required for refrigeration thermostats. Case amperes are listed on the wiring diagram, but always check the serial plate.

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 ue 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 ow 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. Avoid the use of supplemental ood or spot lighting.

Display light intensity has been designed for maximum visibility and product life at the factory.

The use of higher output uorescent lamps (H.O.

and V.H.O.), will shorten the shelf life of the product.

8. Cold coils remove heat and moisture from the case and deposit this as frost onto the coil. Thus, a defrost is required. 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. See Case Specs for Proper

Temperature: Settings.

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 manufacturer’s directions. It is essential to establish and regulate cleaning procedures. This will minimize bacteria causing discoloration which

leads to degraded product appearance and signicantly

shortening product shelf life.

Page 9

Rev. 0508

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 componets 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)

Appendix A. - Temperature Guidelines - Refrigerated

The refrigerators should be operated according to the

manufacturer’s published engineering specications for entering air temperatures for specic equipment applications.

Table 1 shows the typical temperature of the air entering the food zone one hour before the start of defrost and one hour after defrost for various categories of refrigerators. Refer to Appendix C for Field Evaluation Guidelines.

Appendix B. - Application Recommendations Refrigerated

1.0 Temperature performance is critical for controlling bacteria growth. Therefore, the following recommendations are included in the standard.

They are based on conrmed eld 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 the equipment manufacturer’s 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 manufacturer’s recommendations.

b) Observation of outside inuences such

as drafts, radiant heating from the ceiling

and from lamps. Such inuence 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 C. - Field Recommendations - Refrigerated

Recommendations for eld 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 (see Appendix A). In practical use, the precise determination of return

air temperature is extremely difcult. 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 rst 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.

Page 25

Rev. 0508

Appendices (Cont'd)

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 determine 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 rst 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 rst 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?

Is a dumped display causing turbulent air ow 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 airow?

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 ns clear of dirt,

dust, etc.?

19. Is there a shortage of refrigerant?

20. Has the equipment been modied to use

replacements for CFC-12, CFC-502 or other

refrigerant? If so, have the modications 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 Hussmann Corporation provides 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 dened 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.

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.
