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.

GLASS BREAKAGE MAY OCCUR!

Retighten glass along clamshell after leveling and first time case is brought

to full operating temperature!

Glass Adjustment

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 inches.

2. Increase the height to 12 inches, and raise and lower the glass 6 more times.

3. Finally raise the glass to its 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, PLEXIGLASS ALIGNMENT.

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!

This equipment is to be installe d to comply with the applicable NEC, Federal, State , and Local

AT TENTION

INSTALLER

Plumbing and Construction Code ha ving jurisdiction.

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.

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 2 bolts located in the base of the case. Secure the overhead structure by bolting the bracket, located inside behind lights.

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.

Rev. 1209

Installation (Cont'd)

10. Use nger 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.

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.

Bumper Installation Instructions

Step 1: Make sure the aluminum channel and end caps are installed.

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.

DO NOT SEAL JOINT TRIM TO FLOOR!

Step 2: Use silicone lubricant to help the bumper slide into the channel.

Step 3: Starting on one end: while inserting the bumper, push it up against the end cap to prevent the bumper from shrinking after installation (when it gets cold).

Step 4: As you insert the bumper into the channel with one hand, pull the bumper toward you with the other to open the inside lips. Slowly apply pressure by rolling the bumper into the track.

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 xture. There are 3 drains in each xture that can be

easily located. 1-1/2", 1" and 3/4" P-TRAPS and threaded adapters

are supplied with each xture. The 3 P-TRAPS 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.

IGFP-CR3FO-1209

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.

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 CR3FO 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. Defrost times should be as follows: OFF CYCLE - Defrost times should be as directed in the CR3FO technical data sheet. The number of defrosts per day and the duration of the defrost cycle may be adjusted to meet conditions present at your location.

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).

Rev. 1209

Rear Storage

Refrigeration (Cont'd)

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. The front Self Service Evaporator has an EPR valve installed to maintain a constant discharge temperature. It is located in the front at the right side of the case under the fan plenum near the TX valve.

Thermostatic Expansion Valve Location

This device is located on the same side as the refrigeration stub. A Sporlan 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.

4. Subtract the saturation temperature obtained in step No. 2 from the temperature measured in step No. 3. The difference is superheat.

5. Set the superheat for 5°F - 7°F.

Evaporator Pressure Regulator

An Evaporator Pressure Regulator is installed in the front of the self service section to maintain a constant discharge temperature. It is located at the front right side of the case, under the fan plenum near the TX Valve.

Service Case Temperature Control

Temperature control in the upper section of the R3 with the Service Option is done by means of a thermostat and suction solenoid valve. This controls both temperature and humidity.

T-STAT Location

T-STATS are located within the electrical raceway. Refer to diagram below.

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 ow must be unobstructed at all

times to provide proper refrigeration.

6. Keep the service doors closed (when applicable). Refrigeration performance will be seriously affected if left open for a prolonged period of time.

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.

FOR PROMPT SERVICE

When contacting the factory,

be sure to have the Case Model and Serial

Number handy. This information is on a plate

located on the case itself.

Cleaning Glass and Mirrors

Only use a soft cloth and mild glass cleaning 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.

Replacing Fluorescent Lamps

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

ENCAPSULITE

SHATTERPROOF COATING - SA 10645

& OSHA Regulations

NSF

for replacement call:

1-800-395-9229

Turn switch off then on after replacing bulb

Non-glare Glass

Windex® or Glass Plus® are the only solutions 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.

Antistatic Coatings

The 210® has proven to be very effective in not only cleaning and polishing the Plexiglass surface, but also providing antistatic and anti-fog capabilities. This product also seals pores and provides a protective coating.

User Information (Cont'd)

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)

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.

Copper Coils

The copper coils used in Hussmann merchandisers may

be repaired in the eld. Materials are available from local

refrigeration wholesalers. Hussmann recommends using #15 Sil-Fos for repairs.

Tips and Troubleshooting Before calling for service, check the following:

1. Check electrical power supply to the equipment for connection.

2. Check xture loading. Overstocking case will affect

its proper operation.

3. If frost is collecting on xture and/or product, check

that no outside doors or windows are open - allowing moisture to enter store. These merchandisers were designed for use in stores were temperature & humidity does not exceed 75° F and 55% H.

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.

CLEANING PRECAUTIONS

IGFP-CR3FO-1209

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.

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 and 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

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.

Appendix B. - Application Recommendations

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

Rev. 1209

Appendices (Cont'd)

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

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.

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

Appendices (Cont'd)

IGFP-CR3FO-1209

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
