RECEIPT INSPECTION

II. a – RECEIPT INSPECTION
All Traulsen products are factory tested for performance and are free from defects when shipped. The utmost care has been taken in creating this product to protect against damage in transit. All interior fittings have been carefully secured and the legs or casters are boxed and strapped inside to prevent damage. Door keys will be attached to the handle with a nylon strip. The handle is protected by an easily removable nylon netting.
Carefully inspect your Traulsen unit for damage during delivery. If damage is detected, you should save all crating materials and make a note on the carrier’s Bill of Lading describing the damage. A freight claim should be filed immediately. If damage is subsequently noted during or immediately after installation, contact the respective carrier and file a freight claim. Under no condition may a damaged unit be returned to Traulsen without first obtaining written permission (return authorization). You may contact Traulsen customer care at 800-825-8220.

WARNING
Some models may use R-290 (Propane) as a refrigerant. If the flammable refrigerant is present, follow the instructions as labeled on the unit. Proper care must be taken to avoid any damage to the refrigeration system including refrigerant tubing, condenser, and evaporator coils during handling, moving, installation, and cleaning as it may cause a risk of fire or explosion. If damaged, the unit must be moved to a well-ventilated area away from any sources of ignition. Further service and repair must be performed by qualified refrigeration technicians familiar with applicable safety standards for flammable refrigerants. Technicians must use appropriate personal protective equipment and follow applicable safety precautions to avoid the risk of fire or explosion.

 INSTALLATION

III. a – LOCATION
Select a proper location for your Traulsen unit, away from extreme heat or cold. Allow enough clearance between the unit and the side wall in order to make use of the door stay
open feature at 120° (self-closing feature operates up to 90°). The door(s) must be able to open a minimum of 90° in order to make use of the maximum clear door width available.

III. b – PACKAGING
All Traulsen units are shipped from the factory bolted to a sturdy wooden pallet and packaged in a durable cardboard container. The carton is attached to the wooden skid with
the use of large staples. These should first be

III. INSTALLATION (continued)
III. b – PACKAGING (cont’d)
removed to avoid scratching the unit when lifting off the crate. Most exterior stainless steel surfaces have a protective vinyl covering to prevent scratching during manufacturing,
shipping, and installation. After the unit is installed in place of service, remove and discard the covering from all surfaces. To remove the wooden pallet, first if at all possible, we
suggest that the cabinet remain bolted to the pallet during all transportation to the point of the final installation. The bolts can then be removed with a 3/4” socket wrench. Avoid laying the unit on its front, side, or back for removal of the pallet.

NOTE: DO NOT LAY THE UNIT ON ITS SIDE DURING TRANSPORTATION OR INSTALLATION.
Roll-thru models also include special interior wood bracing, intended to protect the cabinet during shipment. This bracing should under no circumstances be removed prior to the unit being installed in its final location.
WARNING Read and review these instructions, in their entirety, BEFORE attempting to disassemble and remove the interior bracing.

If either of the diagonal or upper ceiling braces are dropped, they could cause personal injury or damage to the equipment. To disassemble the bracing, first open the doors and carefully remove the banding that holds the two diagonal braces together.
WARNING The diagonal braces will now be loose and can fall out of position and possibly permit the ceiling corner brace to fall.
Carefully remove one diagonal brace while supporting the ceiling corner brace, so that it does not fall (see figure 1). Next, remove the ceiling brace, the remaining diagonal brace, and lastly the floor brace – then discard. Repeat as necessary for each section of the unit.

III. c – INSTALLING LEGS OR CASTERS

6” High stainless steel legs are supplied standard for all Traulsen reach-in and pass-thru units. Casters in lieu of legs are available as an optional accessories for the same models. These are shipped from the factory packed inside a cardboard box that is strapped to one of the shelves. Remove the nylon strap and open the box, it should contain either four (4) legs or four (4) casters and sixteen (16) bolts.
WARNING THE CABINET MUST BE BLOCKED AND STABLE BEFORE INSTALLING LEGS OR CASTERS.
To install the legs or casters, first, raise and block the reachin a minimum of 7” from the floor. For installing legs, thread the legs into the threaded holes on the bottom of the cabinet (see figure 2). Be certain that all legs are tightly secured (legs and casters should be tightened to 300 inches/pounds, max). When the unit is set in its final position, it is important for proper operation that the unit be level. The legs are adjustable for this purpose; turn the bottom of the leg counter-clockwise to raise it, and clockwise to lower it. Level the unit from front to back as well as side to side in this manner, using a level placed in the bottom of the cabinet.

Please note that Traulsen units are not designed to be moved while on legs. If the unit requires moving, a pallet jack or forklift should be used to prevent damage. For installing
casters, the casters are “plate” type, and require the use of four (4) bolts each to secure them firmly to the cabinet bottom at each corner (see figure 3). The caster bolts are tightened using a 1/2” socket wrench.

III. d – SHELF PINS
The unit is supplied with shelves and shelf pins installed. Check all shelf pins to assure they are tightened down as they may have come loose during shipping. Rotate the pins clockwise until they are secured against the side of the cabinet.

III. e – ROLL-IN MODEL INSTALLATION
Roll-in cabinets set on the floor require the floor area to be flat and level. In addition, after the cabinet is set in place, the sealant should be used around the perimeter of the base to comply with National Sanitation Foundation requirements (see figure 4). After sealing the unit, the enclosed ramp should then be installed.
SEALING THE BASE OF ROLL-IN MODELS

A sealant must be used around the perimeter of the base of the cabinet as shown to fully comply with sanitary requirements.
A recommended sealant is Dow Corning Silastic RTV

A stainless steel threshold ramp(s) is included to facilitate roll-in racks. It is shipped wrapped in brown paper and secured to the rack guides inside the cabinet. To secure it in place, remove the two thumb screws in the breaker strip near the bottom door opening. Next, loosen the thumb screws located along the floor at the threshold. Place the ramp(s) on top of the loosened thumb screws and secure tabs on each end to breaker strips with thumb screws previously removed. After installing the ramp(s), it too should be sealed to the floor.
Bumper strips are secured to the back of roll-in models with thumb screws. Loosen these and make them finger-tight to conform to the requirements of the National Sanitation Foundation (NSF).

III. f – ATTACHING DOUBLE DEPTH UNITS TOGETHER
Double depth roll-in/roll-thru units are shipped as two separate components which must be attached together at the job site. To accomplish this, first, place the front and rear
cabinets in close proximity to each other being careful to align the drain from the front of the rear unit to the drain of the front unit. It will be necessary to level both units together at this time.

III. f – ATTACHING DOUBLE DEPTH UNITS TOGETHER (cont)
Next, using two pipe clamps, pull the units together (see figure 5). Install the covers over the gap formed between the units From inside the cabinets, using the screws provided, install the breaker strips using the strip as a template.

III. g – INSTALLING THE CONDENSATE EVAPORATOR
A condensate evaporator is normally supplied on all self-contained models (remote models require the provision of either a floor drain or an optional condensate evaporator). On those models supplied with a top-mounted evaporator coil compartment, the condensate evaporator is also secured to the top of the cabinet. Check that the condensate pan
is properly located underneath the drain tube.
NOTE: Some models, such as single-section dual-temperature refrigerators/freezers, are supplied with a bottom-mounted condensate evaporator. This is shipped in a cardboard carton secured to the cabinet interior and must be PROPERLY installed prior to use (see instructions supplied with the condensate evaporator).

1. After the cabinet has been uncrated and the legs/casters are attached, you must install the bottom-mounted condensate evaporator.
2. Locate the four (4) holes on the exterior bottom towards the rear of the cabinet.
3. Using the provided 10-32 screws, attach the mounting rails to the bottom, (the folded flange is to be turned up and be towards the drain line).
4. Slide the condensate pan into the mounting rails.
5. Screw the “U-Trap” onto the drain line located on the rear of the cabinet.
6. Screw the drain extension into the “U-Trap”.

NOTE: The use of the “U-TRAP” supplied is required. Failure to use this component may allow cold air to migrate down the drain line, resulting in condensation on the rear of the cabinet.
A remote model is normally supplied configured for condensate to be run to a floor drain unless purchased with a condensate evaporator. The installer is responsible for making the required extension to the floor drain in accordance with good practices and local regulations.

III. h – REMOTE INSTALLATION
Remote models are supplied without compressors, solenoid valves, etc. The correct voltage, amp listing, and refrigerant are listed on the unit’s serial tag. It is the responsibility of the installer to specify and supply the correct size compressor(s) based on this information and on-site requirements.
Refrigerant line installation must be done in accordance with good practices and local regulations. See section “III. g” for information concerning condensate removal for remote models.

III. i – CORD & PLUG
Most self-contained models are supplied with a cord & plug attached. It is shipped coiled at the top of the cabinet, secured by a nylon strap. For your safety and protection, all units supplied with a cord and plug include a special three-prong grounding plug on the service cord. Select only a dedicated electrical outlet with a grounding plug for a power source.
NOTE: Do not under any circumstances, cut or remove the round grounding prong from the plug, or use an extension cord.

III. INSTALLATION (continued)
III. j – POWER SUPPLY
The supply voltage should be checked prior to connection to be certain that the proper voltage for the cabinet wiring is available (refer to the serial tag to determine the correct unit voltage). Make connections in accordance with local electrical codes. Use qualified electricians. Use of a separate, dedicated circuit is required. Size wiring to handle indicated load and provide necessary overcurrent protector in a circuit (see amperage requirements on the unit’s serial tag).

III. k – WIRING DIAGRAM
Refer to the wiring diagram for any service work performed on the unit. Should you require one, please contact Traulsen Service at 800-825-8220, and provide the model and a serial number of the unit involved.

III. i – CLEARANCE
In order to assure optimum performance, the condensing unit of your Traulsen unit MUST have an adequate supply of air for cooling purposes. Therefore, the operating location must either have a minimum of 12” clearance overhead of the condensing unit or allow for unrestricted airflow at the back of the unit. Clearance of at least 12” above is required in order to perform certain maintenance tasks.

 OPERATION

IV. a – REFRIGERATORS
Neither refrigerators nor freezers require manual defrosting. During normal operation, a refrigerator continuously circulates cool air (35°F to 38°F) across the evaporator coil.
A defrost cycle occurs every 8 hours to melt any frost which may have accumulated on the coil. The control will display the cabinet temperature when the defrost starts and activate a LED with the defrost symbol on the controlled display.

IV. b – FREEZERS
During normal operation, a freezer continuously circulates below-freezing cabinet air across the evaporator coil. The coil requires periodic defrosting for proper operation. This is accomplished by an automatic, time activated, temperature/ time terminated, defrost program. The controller is preset at the factory for six equally spaced defrost cycles within each 24-hour period. At the start of a freezer defrost cycle, both the compressor and evaporator fans are OFF.

V. b – FREEZERS (cont’d)
The control will display the cabinet temperature when the defrost starts and activate a LED with the defrost symbol on the display (see figure 7). The electric heater (attached to the coil) is energized. When a temperature sensor affixed to the coil senses 45°F (models with electric defrost), the coil is fully defrosted and the compressor operation is resumed, defrost heaters are automatically turned off. The coil fans are delayed from starting at the termination of a defrost cycle. Fan operation is automatically resumed, or they can also be started by a time or temp delay (whichever comes first). In case of temp delay, it uses the same coil sensor and starts at 32°F. The total refrigeration system operation is then resumed.

During freezer defrost operation, heat is confined to the coil enclosure to prevent any significant rise in temperature within the food zone. The fan delay controls function upon
the termination of a defrost cycle is two-fold. First, to prevent blowing warm air into the food storage area. Second, to prevent any condensation on the defrost coil from being blown into the food storage area. The Smart Control is set from the factory to terminate defrost at 30 minutes in the event of a sensor failure. This setting should never be tampered with, without first consulting the factory.

IV. c – HOT FOOD CABINETS
Hot food cabinet operation is governed by the Smart Control, which controls the ON/OFF operation of the strip heaters. The control can be set to maintain any operational temperature between 130 – 180° F (in 1°F increments) Hot food cabinets are delivered from the factory with the control set to the “OFF” position. Follow the instructions in
section “VI. f” to get started.
NOTE: A vent is included at the top of all hot food cabinets. The vent opening is factory set and secured for the best position. Be certain to make sure this vent is kept free of any obstruction.

CARE & MAINTENANCE

V. a – CLEANING THE CONDENSER
WARNING DISCONNECT THE ELECTRICAL POWER SUPPLY BEFORE CLEANING ANY PARTS OF THE UNIT
The most important thing you can do to ensure a long, reliable service life for your Traulsen is to regularly clean the condenser coil.
The condensing unit requires regularly scheduled cleaning to keep the finned condenser clean of lint and dust accumulation. Keeping the condenser clean allows the cabinet to operate more efficiently and use less energy. To clean the condenser, first, disconnect the electrical power to the cabinet and lift up the front louver assembly. To lift this, remove the two screws located on both sides at the bottom of the louver assembly (see figure 8).

Once the screws are removed, the panel can be pivoted upwards allowing full access to the front-facing condenser (see figure 9).

Vacuum or brush any dirt, lint, or dust from the finned condenser coil, the compressor, and other cooling system parts (see figure 10). If significant dirt is clogging the condenser fins, use compressed air to blow this clear.
Lower louver assembly and replace the screws to hold it in place.

V. a – CLEANING THE CONDENSER (cont’d)
Some Traulsen models come with a StayClear™ Condenser Coil with a finless design. The StayClear Condenser does not require regularly scheduled cleanings but should be cleaned every 6 months or when the finless condenser coil presents a certain level of obstruction of significant dirt on the tubing.
If StayClear Condenser requires cleaning, follow the same steps for cleaning the finned condenser.

V. b – GASKET REPLACEMENT
To remove the gasket to be replaced, grasp it firmly by one corner and pull it out. Before attempting to install a new gasket, both the unit and the gasket itself must be at room
temperature. Insert the four corners first by using a rubber mallet (or hammer with a block of wood). After the corners are properly inserted, work your way towards the center from both ends by gently hitting with a mallet until the gasket is completely seated in place (see figure 11 for proper gasket placement).
NOTE: The gasket may appear too large, but if it is installed as indicated above it will slip into place.

V. c – CLEANING THE EXTERIOR
Exterior stainless steel should be cleaned with warm water, mild soap, and a soft cloth. Apply with a dampened cloth and wipe in the direction of the metal grain. Avoid the use of strong detergents and gritty, abrasive cleaners as they may tend to mar and scratch the surface. Do NOT use cleansers containing chlorine, this may promote corrosion of the stainless steel. Care should also be taken to avoid splashing the unit with water, containing chlorinated cleansers, when mopping the floor around the unit. For stubborn odor spills, use baking soda and water (mixed to a 1 TBSP baking soda to 1-pint water ratio).

V. d – CLEANING THE INTERIOR
For cleaning both stainless steel and anodized aluminum interiors, the use of baking soda as described in section “V. c” is recommended. Use on breaker strips as well as door gaskets. All interior fittings are removable without tools to facilitate cleaning.
V. e – ADJUSTING THE SHELVES
For shelves mounted on pins, first, select the desired location and remove the white plastic covers in the interior back and sides by rotating them counter- clockwise. Remove the shelf pins by rotating them counterclockwise. Install the pins in the desired location by rotating clockwise. Make sure the pin is securely tightened down. Do not over-tighten. Slide the shelf into its new position, and replace the white plastic covers with the holes vacated by the shelf pins.

V. f – REPLACING THE LIGHT BULB
All Traulsen R & A Series models are supplied with LED lighting with the exception of heated units. Optional tube-style display lighting is available (except for sliding glass door
models for which fluorescent lights are supplied standard). The standard LED bulb is a 115 or 230-volt / 4-watt, T-6 intermediate clear refrigerator lamp. It is mounted at the
top front of the cabinet at the center and is located behind a plastic light cover on the refrigerator and freezer model. Heated units RHF/AHF/RIH/AIH/RDH/ADH/RIDH/AIDH) are equipped with 115 or 230-volt / 25-watt, T-6 incandescent bulbs. LEDs have not evolved enough yet to take the heat. This bulb is shatterproof because these models do not include a plastic light cover. To replace the bulb, first, remove the light cover (if so equipped). This can be accomplished by squeezing it together on both sides until it comes free. Replace the light bulb, then squeeze both sides of the light cover together and replace in its original position.

CONTROL BASICS

VI. a – CONTROL DISPLAY
Your new Traulsen Refrigerator, Freezer, or Hot Food cabinet is equipped with state-of-the-art electronic control, which precisely regulates the operation and provides alarms when problems occur. It is supplied from the factory and completely ready for use and requires no adjustment (except for Hot Food units that are set in the “OFF” position).

STAINLESS STEEL OVERVIEW

VIII. a – INTRODUCTION
All Traulsen R & A Series Refrigerator, Freezer, Dual-Temp, and Heated Cabinet models are constructed with a high-quality 430 series, 20 gauge stainless steel exterior finish
(front, sides, and doors). The interior finish on these same R-Series models is constructed using 300 series stainless steel (anodized aluminum is used for A-Series).
The stainless steel finish on Traulsen R & A Series should retain its appearance throughout the product’s usable lifetime. However, some care is required to maintain this appearance. The following paragraphs will provide a guideline on proper care of the exterior/interior finish, as well as some suggestions on how to repair a finish that has been marred due to adverse environmental conditions or improper Jobsite care.

VIII. b – STAINLESS STEEL, HOW IT WORKS
The process by which stainless steel retains its appearance is a result of its type of metal alloy. Steel is a composite of metals combined in a specific industrial process. Stainless
steel contains a high percentage of chromium, the addition of which provides both its appearance and a microscopic surface layer protecting the steel underneath from corrosion. This external layer acts as a barrier, preventing typical oxidation of the steel. Remove this barrier, and the environment will eventually corrode the metal, marring its
appearance.

VIII. c – CAUSES OF CORROSION
Corrosion to stainless steel can only be caused in one of four specific ways:

1. ABRASION
   Abrasion can be caused during routine cleaning of the metal, either by the use of an abrasive cleanser, or the use of an abrasive device, such as a metal scouring pad.
   Abrasion can also be caused by contact with other hard surfaces, such as nearby equipment, walls or tools. Special care should be taken to position your unit properly to prevent accidental dents and scratches.

2. WATER
   Water everywhere contains various deposits, or solids, which as the water dries or evaporates, can leave spots behind. The spots may eventually cause corrosion if not removed.

3. CHEMICALS OR WATER CONTAINING CHLORIDES
   Chlorides, such as those found in water or many cleaning materials are especially corrosive to stainless steel. Daily janitorial duties, such as floor mopping, can splash water containing chlorinated cleansers against the front and sides of a Traulsen refrigeration product, resulting in corrosion. Avoid the use of these on or around a Traulsen refrigeration product if at all possible.

4. PROLONGED CONTACT WITH FOOD PRODUCT
   Many food products, such as milk and carbonated sodas, contain acids that may damage the protective layer of stainless steel. All food and beverage spills should be cleaned up promptly to avoid possible stains and corrosion.

VIII. d – USING THE PROPER TOOLS
The use of proper cleaning materials will do much to prolong the appearance of your Traulsen refrigeration product. We particularly encourage the use of either plastic scouring pads or soft cloths for cleaning stainless steel.
Soft nylon scouring pads can also be used, however, care has to be used to ensure that all scrubbing is done in the direction of the metals “GRAIN”. Because metals are crystalline in nature when they are in a solid state the individual ions line up to form visible grain lines. The use of a soft nylon scouring pad in a direction opposite of the grain will mar its luster. Always do so “PARALLEL” to the grain.
There are several types of tools that should NEVER BE USED when cleaning stainless steel, these include:

• WIRE BRUSHES
• METAL SCOURING PADS
• SANDPAPER
• SCRAPERS & PUTTY KNIVES

Use of any of these tools will result in scratches or removal of the stainless steel’s protective layer, which will eventually lead to corrosion and rust.

VIII. e – USING THE RIGHT CLEANSER
Avoid all cleaning products containing chloride ingredients. The use of a cleanser specifically designed for stainless steel is highly recommended. You may find yourself in a situation
where you are uncertain if a particular cleaning product contains any chlorides. If unsure, it’s probably best to just assume that it does and avoid its use in cleaning a Traulsen
refrigeration product.
Also to be avoided are cleaning products which contain “QUATERNARY SALTS”. These salts can literally attack the stainless steel’s protective layer, leading to corrosion and pitting of the surface of the steel.
After cleaning, it is important to always rinse the cleaned area thoroughly with cool, clean water (do not use hot water) and wipe completely dry using a paper towel or soft absorbent cloth.

VIII. e – USING THE RIGHT CLEANSER (cont’d)
Use of cleaning products designed for use on stainless steel, in conjunction with the proper tools, as outlined above will help retain the appearance of your Traulsen refrigeration product for years and years.

VIII. f – CLEANING SUMMARY – DO’S & DONT’S
To summarize the proper cleaning of Traulsen refrigeration products, always follow the below guidelines.
DO use only cleaning products designed for stainless steel or cleaning products that do not contain chlorides.
DO use only non-abrasive cleaning materials, such as soft cloths or plastic scouring pads.
DO clean up food and beverage spills ASAP.
DO scrub only in the direction of the grain when using soft nylon scouring pads.
Don’t use chlorinated cleansers or cleansers containing quaternary salts.
Don’t use abrasive cleaning materials or tools which can scratch the stainless steel’s surface.

VIII. g – ACCIDENTAL CHLORIDE CONTACT
In the daily routine of a busy food service operation, your Traulsen refrigeration product may occasionally come in contact with chlorinated cleaners, such as when being splashed during mopping. Stain and corrosion problems resulting from this can be avoided by prompt action to remove this cleanser. Rinse the affected area(s) thoroughly with cool, clean water (do not use hot water) and wipe completely dry using a paper towel or soft absorbent cloth.

VIII. h – PROTECTING STAINLESS STEEL SURFACE
Occasional use of a commercial stainless steel polish, such as “Sheila Shine,” will help protect the surface of stainless steel. Follow the directions on the spray can for proper use.
VIII. i – RUST AFTER THE FACT
Although Traulsen strongly recommends proper care and cleaning of stainless steel finishes in order to avoid rust and corrosion before it occurs, we recognize that it may occur
occasionally as a result of the causes described in the section “VIII. c.”.
To remove small quantities of rust from the surface of stainless steel, it is far preferable to deal with this when it first becomes visible. When rust occurs, do not allow it to  remain for any period of time, and remove it using the following method:

VIII. i – RUST AFTER THE FACT (cont’d)

1. Use a lightly abrasive compound (free of harmful chlorides), such as “Bon Ami,” on a soft cloth, to remove the rust. Care must be taken to rub this on the area of rust only in the direction of the stainless steel’s grain.

2. Once the rust is removed, clean the affected area thoroughly with a stainless steel cleaner (see section VIII. e).

3. Apply a preservative polish, such as “Sheila Shine,” to the affected area (see section VIII. h).
   VIII. j – EXTREME RUST SITUATIONS
   In the event that rust and corrosion were not dealt with promptly, more acute situations can be remedied as follows:
   NOTE: THE PROCEDURE REQUIRES THE USE OF AN ACID-BASED SOLUTION – THE USE OF PROTECTIVE GLOVES AND EYEWEAR IS REQUIRED BEFORE PROCEEDING.

4. In a clean spray bottle combine water with “Zep FS Lime Remover” to make a 5 parts to 1 solution.

5. Apply this solution to the affected area with either a clean cloth or a sponge.

6. After application, wipe the same area thoroughly clean with water only to remove any residue.

7. Once cleaned, apply a light coat of “Zep Restore” to the surface area. This will serve to preserve the metal and help prevent future rust from occurring.

8. Restore the remaining stainless steel surfaces to their original shine using “Zep Stainless Steel Polish.”
   Repeat steps one through five if necessary for stubborn rust and corrosion areas.

VIII. k – RESTORING THE PROTECTIVE LAYER
There are several products available on the market today which can actually help restore the “PASSIVATION” of stainless steel. “PASSIVATION” refers to the protective qualities of the non-reactive surface layer of stainless steel which prevents oxidation. Contact your cleaning supplier for product recommendations and more information.
