RECEIPT INSPECTION

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.
• You should carefully inspect your Traulsen unit for damage upon delivery.
• If damage is detected, you should save all the 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 our customer care team to file a freight claim.
• There is a fifteen (15) day limit to file freight damage with the carrier.
• Under no condition may a damaged unit be returned to Traulsen without first obtaining written permission (return authorization).
• You may contact Hobart/Traulsen customer care at 800-333-7447 to request a return or file a claim.

INSTALLATION

LOCATION

• Select a proper location for your Traulsen unit, away from extreme heat and allow proper clearance for air circulation (see section III.f).

PACKAGING

• The Traulsen unit is shipped from the factory secured to a sturdy wooden pallet with a steel strap and packaged in durable wood crating.
• Most exterior stainless steel and aluminium 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 strapped to the pallet during all transportation to the point of final installation.
• The strap can then be removed with metal shears. Be careful as the steel strap is under tension and will release once cut.
• NOTE: Traulsen does not recommend laying the unit down on its front side or back.
• However, if you must only lay the unit on the front of the side, not the back please be certain to allow the unit to remain in an upright position afterwards for 24 hours before plugging it in so that the compressor oils and refrigerant may settle.

LEGS OR CASTERS

• This Traulsen product is shipped from the factory with casters installed. Level the cabinet using a level or pan of water at the bottom of the cabinet.
• Legs are available as an optional accessory kit. These are shipped inside the cabinet in a cardboard box.
• THE CABINET MUST BE BLOCKED AND STABLE BEFORE INSTALLING LEGS.
• 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.
• To install the legs, first raise and block the cabinet a minimum of 7” from the floor.
• Thread the legs into the threaded holes on the bottom of the cabinet (see Figure 1).
• Be certain that all legs are tightly secured. 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 counterclockwise to raise it, and clockwise to lower it. Level the unit from front to back as well as side to side in this manner.

CORD & PLUG

• All Traulsen models are supplied with a cord & plug attached.
• It is shipped coiled and secured by a nylon strip to the back of the cabinet near the condensing unit area. 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.

POWER SUPPLY

• The supply voltage should be checked before 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 under local electrical codes.
• Use qualified electricians.
• The use of a separate, dedicated circuit is required. Size wiring to handle the indicated load and provide the necessary over-current protector in a circuit (see amperage requirements on the unit’s serial tag).

CLEARANCE

• To assure optimum performance, the condensing unit of your Traulsen unit MUST have an adequate supply of air for cooling purposes.
• Therefore, 1” stoppers in the back are integral part of the unit. Space around these stoppers should not be blocked to provide proper air exhaust.
• There are no clearance requirements for the sides.
• NOTE: Do not install the cabinet without casters.

OPERATION

Both refrigerators and freezers do not require manual defrosting. However, a manual defrost option is available on the control, if required.

OPERATION DISPLAY INDICATORS

During normal operation, the display shows either the temperature measured or one of the following indications:

FREEZERS

• During normal operation, a freezer continuously circulates below-freezing cabinet air through the evaporator coil.
• The coil requires periodic defrosting for proper operation An electric defrost occurs every 7 hours for a maximum length of 30 minutes to melt any frost which may accumulate on the coil during the compressor “ON” cycle.
• At the start of a freezer defrost cycle, both the compressor and evaporator fans are off.
• The microprocessor control will read “dEF” (see Figure 1).
• The electric heaters (attached to the evaporator coil and drain tube) are energized. When the temperature sensor affixed to the coil senses 50°F, the coil and drain pan are fully defrosted.
• Both heaters and compressor are off for 5 minutes to let the defrost water drip out completely. After drip time, the compressor will resume operation.
• The evaporator coil fans are delayed from starting at the termination of a defrost cycle. Fan operation is automatically resumed, after a short time or temp delay (whichever comes first). After completion, the total refrigeration system operation is then resumed.
• During defrost operation, heat is confined to the coil enclosure to prevent any significant rise in temperature within the food zone.
• The fan delay control function upon 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 microprocessor control is set from the factory to terminate defrost at 30 minutes for freezers in the event of a sensor failure. This setting should never be tampered with, without first consulting the factory.

REFRIGERATORS

• During normal operation, a refrigerator continuously circulates above-freezing cabinet air through the evaporator coil.
• An electric defrost occurs every 8 hours for a maximum length of 30 minutes to melt any frost that may accumulate on the coil during the compressor “ON” cycle.
• The defrost process is the same as the freezer described in the previous section.
• With standard holding refrigerators, high relative humidity is also maintained to prevent dehydration of stored products.

REFRIGERATING PRODUCT

• The Flex Drawer will satisfactorily refrigerate an assorted load of food items.
• Allow space above the food bin to permit free air circulation.
• Do not overload at any one time with warm food products and expect immediate results. A certain amount of time is required to remove heat from items before operating temperatures can be attained.
• The system is designed for the storage of refrigerated or frozen products.
• Opening the drawer will increase the temperature in the cabinet and will require a certain amount of time to recover.
• Also, after peak service periods or after the warm product is loaded, the refrigerator will require a certain amount of time for the temperature to return to the normal operating range.

DRAWER LOADING

• The product should be placed in a way that ensures air can circulate.
• Do not operate without the ABS bin in place (see Figure 2).

CARE & MAINTENANCE

WARNING: DISCONNECT ELECTRICAL POWER SUPPLY BEFORE CLEANING ANY PARTS OF THE UNIT.

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 cleaners containing chlorine, this may promote corrosion of the stainless steel.

CLEANING THE INTERIOR

• For cleaning the interior, use baking soda with warm water, and a soft cloth.
• Apply with a dampened cloth and wipe in the direction of the metal grain Use on breaker strips as well as door and drawer gaskets.

CLEANING THE CONDENSER FAN GUARD

• The condenser fan guards function as a filter in this cabinet. Check the fan guard periodically by pulling outward on the lower louvre panel.
• The operating environment will affect the required frequency of cleaning. Air must be able to freely circulate through the condenser.
• The air intake of the fan guard must be kept free of dirt and grease for proper system operation.
• The condenser fan guard is at the front of the cabinet, behind the louvre panel. Carefully clean dirt and lint from the condenser fan guard using a vacuum cleaner or soft brush; do not use a wire brush.

CONDENSATE REMOVAL SYSTEM CARE

• Condensate removal happens by evaporation at the bottom of the cabinet with a hot gas tube.
• The unit does not need a drain. The evaporator coil, condensate loop and condensate pan can all be flushed with fresh water by a qualified service technician if needed.

PREPARING FOR EXTENDED SHUTDOWN

• If the refrigerator is not to be used for an extended period, disconnect the electrical power supply and open the drawers.
• As soon as the cabinet has warmed up to room temperature, wipe out the interior.
• Leave the drawers open and check again to make sure that no moisture has collected on any parts.
• To restart the refrigerator, follow the instructions under PRESTART CHECKS and OPERATION.

ADJUSTING THE DRAWERS

• Occasionally the drawer(s) may require alignment adjustment.
• To do so, first, open the drawer and loosen the drawer face mounting screws enough to move the drawer face.
• Do not completely remove the screws. Next, adjust and level the drawer face as needed and tighten the screws.

DRAWER GASKET REPLACEMENT

• To replace the gasket, grasp it firmly by one corner and pull it out.
• Before attempting to install a new gasket, both the unit and gasket 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 centre from both ends by gently hitting with a mallet until the gasket is completely seated in place (see Figure 5 for proper gasket placement).

CONTROL BASICS

Your new Traulsen unit is equipped with a digital control, which precisely regulates operation. It is supplied from the factory completely ready for use.

INFORMATION MENU

The information available in this menu is:

• displayed only if enabled (see Configuration Parameters)
• displayed only if ACC > 0

Access to the menu and information displayed:

• Press and immediately release the button .
• With a button or select the data to be displayed.
• Press the button to display the value.
• To exit from the menu, press a button or wait for 10 seconds.

Initiate Stand-By:

• Keeping the button pressed for 3 seconds allows the controller to be put on standby or output control to be resumed (with SB=YES only).

Locking the Keypad:

• The keypad lock avoids undesired, potentially dangerous operations, which might be attempted when the controller is operating in a public place.
• In the INFO menu, set parameter LOC = YES to inhibit all functions of the buttons. To resume normal operation of the keypad, adjust the setting so that LOC = NO.

INFORMATION MENU

Selection of Second Parameter Group: It’s possible to select control parameters between two different pre-programmed groups, for the fundamental control parameters to be adapted quickly to changing needs. Changeover from Group I to Group II (and vice versa) may take place MANUALLY by pressing the button for 2 seconds (with IISM = MAN), or AUTOMATICALLY when ECO conditions are detected (with ISM = ECO), or when IISM = DI, DxO = IISM and the digital input is activated (the activation of DIx selects Group II, x = 1,2,3). If IISM = NON, switchover to Group II is inhibited. The activation of Group II is signalled by the lighting up of the relevant LED on the controller display.

ADJUSTING CABINET SETPOINT

• Setpoint display and modification:
  • Press the button for at least a half second to display the setpoint value.
  • While keeping the button pressed, use a button or to set the desired value (adjustment is within the minimum SPL and the maximum SPH limit).
  • When the button is released, the new value is stored.

INITIATING A DEFROST

• Automatic defrost: Defrost starts automatically as soon as the time set with parameter DFT has elapsed.
• Timed defrost: With DFM = TIM defrosts take place at regular intervals when the timer reaches the value of DFT. For example, with DFM = TIM and DFT = 36, a defrost will take place every 6 hours.
• Optimized defrost: With DFM = FRO the timer is only increased when the conditions occur for frost to form on the evaporator, until the time set with parameter DFT is matched. If the evaporator works at 0°F, defrost frequency depends on the thermal load and climatic conditions. With setpoints much lower than 0°F, defrost frequency mainly depends on the refrigerator operating time.
• Defrost time count backup: At the power-up, if DFB = YES, the defrost timer resumes the time count from where it was left off before the power interruption. Vice versa, with DFB = NO, the time count re-starts from 0. On standby, the accumulated time count is frozen.
• Manual or remote defrost start: It’s possible to manually start a defrost, by pressing the button for 2 seconds.
• Defrost type: Once the defrost has started, the Compressor and Defrost outputs are controlled according to parameter DTY. If FID = YES, the evaporator fans are active during defrost.
• Defrost termination: The actual defrost duration is influenced by a series of parameters.
• Time termination: T2 = NO and T3 different from 2EU: the evaporator temperature is not monitored and defrost will last as long as time DTO.
• Temperature monitoring of one evaporator: T2 = YES and T3 different from 2EU. In this case, if the sensor T2 measures the temperature DLI before the time DTO elapses, defrost will be terminated in advance.

Resuming thermostatic cycle:

• When defrost is over, if DRN is greater than 0, all outputs will remain off for DRN minutes, for the ice to melt completely and the resulting water to drain.
• Moreover, if probe T2 is active (T2 = YES), the fans will re-start when the evaporator gets to a temperature lower than FDD; Vice versa, if probe T2 is not active (T2 = NO) or after defrost has come to an end, such condition does not occur by end of the time FTO after FTO minutes have elapsed the fans will be switched on anyway.
• Caution: if DFM = NON or C-H = HEA all defrost functions are inhibited; if DFT = 0, automatic defrost functions are excluded.

CONFIGURATION PARAMETERS

• Parameter Configuration:
  • To get access to the parameter configuration menu, press a button and for 5 seconds.
  • With button or select the parameter to be modified.
  • Press the button to display the value.
  • By keeping the button pressed, use a button or to set the desired value.
  • When the button is released, the newly programmed value is stored and the following parameter is displayed.
  • To exit from the setup, press the button or wait for 30 seconds.
