Proper case joint sealing is

extremely important to

prevent water leaks.

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 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.

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. The fronts of the cases should be in alignment. Caution: do not use

connecting bolts to pull sections together.

4. Apply a thick bead of silicone to adjoining end panels as illustrated in the following diagram, especially around bulkhead cutouts and screw holes. Apply liberal bead of case joint sealant (grey silicone) between cases along bulkhead and up the rear discharge (clear silicone). Do not use Permagum because this does not allow cases to draw up tight, and therefore leaves gaps at the joint.

5. Bolt* sections together. Typical bolt locations are illustrated below.

6. Attach bulkhead caps* with silicone*.

7. Slide PVC collar* (23/8-3”) through bulk head at the humidity system plumbing cut outs. Secure the collar with 2-part epoxy. Seal joint with silicone*. Fill collar by encapsulating piping with expanding urethane foam*.

8. Connect applicable electrical, refrigeration, water, and drain lines. See respective chapters for more detailed instructions.

9. After cases have been leveled and refrigeration, electrical, and waste piping work completed, install the splashguards. (see instructions in the “Finishing Touches” section of this booklet).

Note: Seal the unit to the oor with an NSF Listed caulk or

equivalent

Corner Wedges

Corner wedges are attached via front and rear camlocks. Use a 7mm allen wrench to turn the locks. Do not overtighten! Join the top by using a joint bracket (included in joint kit) with 3/8” bolts.

Joint Trim

After cases have been leveled and joined, and 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.

Plumbing

The DSF 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:

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.

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.

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.

General Description

One cont ributor to the spoil age 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 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 humidication systems. Maintenance is almost unnecessary if you follow a few simple rules:

1. Keep the case clean.

2. Keep the water lter 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 ushing with a hose.

Humidification

• Set thermostat to cut in at the discharge temperature designated in the case specications section of the appropriate installation guide or specication 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 Specications 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.

Humidification (Cont'd)

• 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.

Humidication System Hookups

Remove the raceway panel on the lower back of the case. The pre-piped water shut-off valve and the water lter are located on the left hand side of the case. The water line (which is a 1/4” OD copper tting) can be connected to the ball shut-off valve, by means of a compression tting (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 purge the line to ush any debris that may clog the water lter. 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 ow, and purge. By doing this as a precautionary measure, you may avoid problems and repeat servicing.

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 ow arrows. Turn on the water, by turning the ball valve in the direction of the ow (OFF is at 90° to the direction of ow).

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.

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.

Maintenance

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

HUMIDITY SYSTEM as viewed from the front.

Note: The axial fans included in the humidity system must be

replaced as a unit.

Manifold Flush System

General Description

Twice a day for two (2) minutes, a high pressure water stream will ush most residue build-up from the bottom of the manifold chamber. This is the area that residue builds and expands from. Frequency of this periodic maintenance will vary depending on water mineral content and sanitary conditions.

Automatic Flush System

Electrical components are located within the electrical raceway. Electrical components in this area are 115V AC. Step-down transformer is located in wire-way, and is controlled by pump switch. Water ow for ush system is rated at 0.25 GPM at 60PSI water pressure. Flush nozzle located in the rear of the case.

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.

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 DSF, DSFM technical data sheet 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 be as directed in the DSF, DSFM 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.

Basic System Operation:

1. Filtered water is supplied to the 115V solenoid

valve.

2. At a time of day determined by you, the 115V time clock will energize the solenoid for 2 minutes.

Start Up:

1. Manually move time clock to initiate a ush cycle.

2. Observe that ush nozzle is spraying down center of manifold chamber.

3. Set clock to correct time of day.

4. Set trip pins to the “time of day system is to ush” (NOTE: 2 ush/day!)

Manual Flush System

Water valve is located on the outside of the case, in the rear, on the left hand side as viewed from the rear.

Access to TX Valves and 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 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.

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.

Page 26

NOTE: Only one T- stat per lineup.

T-Stat

Center Display

Refrigeration (Cont'd)

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 of the 4’ or 5’ main section of the case. In all the cases, the T-STAT is located on the same side of the case. If you are looking at the case from the back, it is on the left hand side.

Wiring Color Code

CASE MUST BE GROUNDED

NOTE: Refer to label illustrated above that is afxed to case

to determine the actual conguration as checked in the

“TYPE INSTALLED” boxes.

Electrical Circuit Identication

Standard lighting for all models will be full length uorescent lamps located within the case at the top.

The switch controlling the lights, the plug provided for digital scale, and the thermometer are located at the rear of the case mullion.

The receptacle that is provided on the exterior back of these models is intended for computerized scales with a ve amp maximum load, not for large motors or other high wattage appliances. It should be wired to a dedicated circuit.

Electrical Service Receptacles (When Applicable)

The receptacles located on the exterior of the merchandiser are intended for scales and lighted displays. They are not intended nor suitable for large motors or other external appliances.

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

The DSF, DSFM has no lights other than Optional Ledge lights. The ballasts for ledge lights are located in the xture itself.

Page 33

Electrical (Cont'd)

Wiring Halogen Lights

Halogen lamps must not be operated above recommended rated voltage. They should be wired on a 3 wire, 3Ø system with a neutral. Feed the lights from the balanced leg if you have a high leg.

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. 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 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.

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°F!

Set thermostat to cut in at 28°F discharge air. Meat holding box: 32°F. Meat prep room: 55°F. Meat bloom box: 36°F. Process the meat to enter case at 40°F or below. Product deterioration is very rapid above 40°F.

CLEANING PRECAUTIONS

When cleaning:

• Do not use high pressure water hoses

• Do not introduce water faster then waste outlet can drain

• NEVER INTRODUCE WATER ON SELF CONTAINED UNIT

WITH AN EVPORATOR PAN

• NEVER USE A CLEANING OR SANITIZING SOLUTION THAT HAS AN OIL BASE (these will dissolve the butyl sealants) or an AMMONA 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 A CHLORANITED CLAENER ON ANY SURFACE

• DO NOT USE ABRASIVES OR STEEL WOOL SCOURING PADS (these will mar the finish)

CAUTIO

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 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.

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 ood.

3. Apply the sanitizing solution according to the manufacturer’s directions.

4. Rinse thoroughly.

5. Dry completely before resuming operation.

Cleaning Glass and Mirrors

Only use a soft cloth and water 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 rst.

User Information (Cont'd)

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 the glass clean.

Water is the only solution recommended to be used to clean the 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 to prevent solutions from splashing onto the glass and ruining the coating on the inside.

Plexiglass and Acrylic Care

Improper cleaning not only accelerates the cleaning cycle but also degrades the quality of this surface. Normal daily bufng 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 marketed 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.

Note: The base channel insert must slide out in order to be

cleaned. A hose can be used for cleaning purposes of this base insert channel only when no end panel is provided on the case.

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.

Fluorescent lamps are furnished with a shatterproof protective coating. The same type of lamp with protective coating must be used if replaced.

Evaporator Fans

The evaporator fans are located at the center front of these merchandisers directly beneath the display pans.

Should fans or blades need servicing, always replace fan blades with the raised embossed side of the blade TOWARD THE MOTOR.

Stainless Steel Cleaning and Care

There are three basic things, which can break down your stainless steel’s passivity layer and allow corrosion.

1. Mechanical Abrasion

Mechanical Abrasion means those things that

will scratch the steels surface. Steel Pads, wire Brushes, and Scrapers are prime examples.

2. Water

Water comes out of our tap in varying degrees of

hardness. Depending on what part of the country you live in, you may have hard or soft water. Hard water may leave spots. Also, when heated, hard water leaves deposits behind that if left to sit, will break down the passive layer and rust your stainless steel. Other deposits from food preparation and service must be properly removed.

3. Chlorides

Chlorides are found nearly everywhere. They

are in water, food and table salt. One of the worst perpetrators of chlorides can come from household and industrial cleaners.

Page 36

Maintenance (Cont'd)

Don’t Despair! Here are a few steps that can help prevent stainless steel rust.

1. Use the Proper Tools

When cleaning your stainless steel products, take

care to use non-abrasive tools. Soft Clothes and plastic scouring pads will NOT harm the steel’s passive layer. Stainless steel pads can also be used but the scrubbing motion must be in the same direction of the manufacturer’s polishing marks.

2. Clean With the Polish Lines

Some stainless steels come with visible polishing

lines or “grain”. When visible lines are present, you should ALWAYS scrub in a motion that is parallel to them. When the grain cannot be seen, play it safe and use a soft cloth or plastic scouring pad.

3. Use Alkaline, Alkaline Chlorinated or Non-chloride Containing Cleaners

While many traditional cleaners are loaded

with chlorides, the industry is providing an ever increasing choice of non-chloride cleaners. If you are not sure of your cleaner’s chloride content contact your cleaner supplier. If they tell you that your present cleaner contains chlorides, ask for an alternative. Also, avoid cleaners containing quaternary salts as they also can attack stainless steel & cause pitting and rusting.

4. Treat your Water

Though this is not always practical, softening hard

water can do much to reduce deposits. There are certain lters that can be installed to remove distasteful and corrosive elements. Salts in a properly maintained water softener are your friends. If you are not sure of the proper water treatment, call a treatment specialist.

5. Keep your Food Equipment Clean

Use alkaline, alkaline chlorinated or non-chlorinated

cleaners at recommended strength. Clean frequently to avoid build-up of hard, stubborn stains. If you boil water in your stainless steel equipment, remember the single most likely cause of damage is chlorides in the water. Heating cleaners that contain chlorides has a similar effect.

6. RINSE, RINSE, RINSE

If chlorinated cleaners are used you must rinse,

rinse, rinse and wipe dry immediately. The sooner you wipe off standing water, especially when sit contains cleaning agents, the better. After wiping the equipment down, allow it to air dry for the oxygen helps maintain the stainless steel’s passivity lm.

7. Never Use Hydrochloric Acid (Muriatic Acid) on Stainless Steel

8. Regularly Restore/Passivate Stainless Steel

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 44

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?

5. 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.

Page 45

Appendices (Cont'd)

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.
