RECEIPT INSPECTION

RECEIPT INSPECTION

All Centerline products are factory tested for performance and are free from defects when shipped. The utmost care has been taken in crating this product to protect against damage in transit.

You should carefully inspect your Centerline unit for damage upon delivery. If damage is detected, you should save all the crating materials and make note on the carrier’s Bill of Lading describing this. 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 returnedto Traulsen without first obtaining written permission (return authorization). You may contact Traulsen customer care at 800-333-7447 and select option 2 to request a return.

INSTALLATION

a – LOCATION
Select a proper location for your Centerline 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.

NOTE: Do not install the cabinet without casters.

b – PACKAGING
All Centerline units are shipped from the factory bolted to a sturdy wooden pallet and packaged in a durable cardboard container.

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 final installation. The bolts can then be removed with a 5/8” socket wrench by tipping or otherwise raising the unit to allow access to them.

NOTE: Traulsen does not recommend laying the unit down on its front or side or back. However, if you must only lay unit on the front of side, not the back and 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.

c – INSTALLING LEGS OR CASTERS
A set of 4” high casters are supplied standard for all compact undercounter and prep table units. These are shipped from the factory inside a cardboard box which is secured inside the cabinet.

THE CABINET MUST BE BLOCKED AND STABLE BEFORE INSTALLING CASTERS.

The “Stem” casters are installed by threading them firmly into the cabinet bottom at each corner ( see figure 1).

For leveling, turn the casters counterclockwise to raise it, clockwise to lower it. Level the unit from front to back as well as side to side in this manner. The caster bolts are tightened using a 1/2” socket wrench. Casters with locks should be installed in the front for easy access to locking mechanism. Legs & 6” casters are available in lieu of 4” casters as an optional accessory kit for the same models. These are shipped inside a separate cardboard box containing four (4) casters/legs.
To install the legs or casters, first raise and block the cabinet 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. 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, clockwise to lower it. Level the unit from front to back as well as side to side in this manner

d – INSTALLING DRAIN PAN
Centerline compact models are shipped with the condensate pan (half-size sheet pan) wrapped up and stored inside the unit.
Remove the condensate pan and slide it on the rails underneath the cabinet. Route the drain tubing drain into the pan to ensure water drains into the pan (see figure 2).

NOTE: DRAIN PAN IS DESIGNED TO HOLD AND EVAPORATE DEFROST CONDENSATE FROM THECABINET DURING NORMAL OPERATIONS. HOWEVER, DUE TO OTHER OPERATIONS LIKE FLOOR CLEANING WITH WATER JETS/SPRAYS, IT MAY GET FULL AND OVERFLOW. IN THOSE CASES, DRAIN PAN CAN BE SLIDED OUT AND EMPTIED TO PREVENT SLIP HAZARD

e – SHELF CLIPS FOR DOOR MODELS

Shelves and shelf clips are shipped with the unit. Shelves are mounted on pilasters using clips to adjust the shelf height. For each shelf, insert four (4) shelf clips into the pilaster slots at the same height. The shelf clips have a small projection on top which holds the shelf in position and prevents it from slipping forward. To remove the clips, pinch down on the mounting side and pull them outwards. Make sure the clips are securely installed. Lastly, set the shelf into its new position

f – CORD & PLUG
All Centerline compact 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 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 grounding plug for power source.
NOTE: DO NOT UNDER ANY CIRCUMSTANCES CUT OR REMOVE THE ROUND GROUNDING PRONG FROM THE PLUG OR USE AN EXTENSION CORD

g – POWER SUPPLY
The supply voltage should be checked prior to connection to be certain that proper voltage for the cabinet wiring is available (refer to the serial tag to determine correct  unit voltage). Make connections in accordance with localelectrical codes. Use qualified electricians.

Use of a separate, dedicated circuit is required. Size wiring to handle indicated load and provide necessary over current protector in circuit (see amperage requirements on the unit’s serial tag).

h – CLEARANCE
In order to assure optimum performance, the condensing unit of your Centerline unit MUST have an adequate supply of air for cooling purposes. Therefore, the operating location must have a minimum of 1” clearance on top of the unit for proper air flow. There are no clearance requirements for the sides or rear.

i – CUTTING BOARD ASSEMBLY
On prep tables and mega top tables, the cutting board mayrequire assembly at the site. Install cutting board brackets on each side with two screws. With brackets installed, slide the cutting board in at an angle under the lip in the back and then let it rest down with the pins running through the holes on the board (see figure 4 ).

The cutting board is field reversible, reverse process to reverse cutting board.

j – INSTALLING BACKSPLASH
All 27”, 36”, 48”, 60”, & 72” wide compact undercounter models can be supplied with an optional backsplash that must be installed on-site. To do so, please follow the directions below:

1. Install backsplash as shown in figure 5.
   
   The backsplash is attached with self-drilling Philips head screws. The outer most holes are used to install bumpers.

2. Align the outer holes used for the bumpers to attach the backsplash. Attach the backsplash with the just the outer holes and bumpers temporarily to hold in place.

3. Assure the front lip of the backsplash is contacting the top of the unit. Use the self-threading sheet metal screws to attach the inner portion through the hole locations on the backsplash.

4. Use silicone or similar product to seal any gaps between the backsplash and the exterior top.

OPERATION

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

a – OPERATION DISPLAY INDICATORS
During normal operation, the display shows either the temperature measured or one of the following indications:

b – REFRIGERATORS
During normal operation, a refrigerator continuously circulates above-freezing cabinet air through the evaporator coil. An Off-Cycle defrost occurs every 8 hours for a maximum length of 50 minutes to melt any frost which may accumulate on the coil during the compressor “ON” cycle. With standard holding refrigerators, high relative humidity is also maintained to prevent dehydration of stored product.

c – FREEZERS
During normal operation, a freezer continuously circulates below-freezing cabinet air through the evaporator coil. The coil requires a periodic defrosting for proper operation. This is accomplished by an automatic, compressor runtime activated, temperature/time terminated, defrost program. Depending on the door opening frequency and the ambient condition, the defrost may occur 3 to 8 times within each 24-hour period.

At the start of a freezer defrost cycle, both the compressor and evaporator fans are off. The microprocessor control will read “dEF” (see figure 6).

CARE AND MAINTENANCE

The electric heaters (attached to the evaporator coil and drip pan) are energized. When the temperature sensor affixed to the coil senses 50°F, the coil and drip pan are fully defrosted. Both heaters and compressor are off for 5 minutes to let the defrost water drip out completely. After drip time, 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 25 minutes for freezers in the event of a sensor failure. This setting should never be tampered with, without first consulting the factory.

d – PREP TABLE & MEGA TOP REFRIGERATOR
The prep table and mega top refrigerator will function as a refrigerator. Due to the open top feature, it runs slightly lower evaporator temperature and builds more frost on coil than the regular refrigerator. The prep table and mega top therefore utilize electric heater for more effective defrost. The defrost procedure is the same as in freezer described in section IV.c, except the defrost will be terminated at 45°F.

e – REFRIGERATING PRODUCT
Centerline compact models will satisfactorily refrigerate an assorted load of food items. Allow space between articles 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 storage of refrigerated or frozen product. Opening the door or 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 warm product is loaded, the refrigerator will require a certain amount of time for the temperature to return to the normal operating range.

f – DIVIDER BARS
Top Rail: Centerline compacts are provided with standard width pan divider bars. Pans are not provided with the unit.

Drawers: Drawer models are provided with metal divider bars standard. All 27” wide models are supplied with standard width bars. 48” and 72” models are supplied with 2 narrow and 2 wide bars.

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

a – 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.

b – 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.
All door models interior fittings are removable without tools to facilitate cleaning. Depending on the level of cleaning, drawer model interior fittings may require a tool to facilitate cleaning. The drawer frame may be removed without tools.

To remove the drawers, the lock tab must be unlocked by sliding the lock tab forward and then up, to loosen the slides (see figure 8).

Then the drawer can be pulled out easily. from the slides.
Drawer lock tab shown in unlocked position.

To remove the middle slide between the drawer and cabinet for deeper cleaning, remove the middle slide by lifting up on the back tab and sliding it out of the track

Caution: The outer slides attached the side of the cabinet should not be removed because there are washers set in the assemble to hold the proper spacing between the slides. If removed the drawer slides may not function properly

CLEANING THE CONDENSER COIL
Check the condenser coil periodically. The operating environment will affect the required frequency of cleaning. Air must be able to freely circulate through the condenser. This surface must be kept free of dirt and grease for proper system operation. The condenser coil is at the back of the cabinet. Carefully clean dirt and lint from the condenser coil using a vacuum cleaner or soft brush; do not use a wire brush.

d – CONDENSATE REMOVAL SYSTEM CARE
Condensate removal is provided by evaporation at the pan at the bottom of the equipment cabinet and does not need a drain. The evaporator coil, condensate loop and condensate pan, when needed, can all be flushed with fresh water by a qualified service technician. This should be part of any routine maintenance program and can prolong the life of the equipment. Clean the condensate removal pan by wiping it out with a clean damp cloth. Replace the pan back to its location

e – DOOR RE-HINGING
The door(s) on all compact models can be easily re-hinged in the field. Existing hinge cartridge and top hinge bracket can be reused but an opposite side bottom hinge bracket will be needed. This bracket can be obtained from the factory by contacting our parts department (see section VIII.b) To begin, open the door to its stay-open feature position. Support the non-hinged end of the door so that minimum movement occurs when the bolts from the lower hinge brackets are removed. Remove the lower hinge bracket and then the door from the top hinge bracket. The hinge bracket pin and plastic bushing will remain in the top hinge bracket.

Carefully lay the door down on a padded flat surface. The door must be rotated 180° to mount on the other side of cabinet. Remove top bushing and bottom hinge cartridge and install on opposite ends. Using the newly obtained bottom hinge bracket, follow the steps in reverse order to re-hinge the door.

NOTE: The lower hinge plate is under spring tension. Grasp the lower hinge plate while keeping a firm grip on the plate, carefully slide it out the bottom of the door just far enough to allow the plate to rotate a full 360°. Unwind the tension of the spring by carefully allowing the hinge plate to rotate a full 360 degrees several times.

f – ADJUSTING THE DOOR
Occasionally the door(s) may require alignment adjustment. To do so, first open the door and loosen the hinge plate screws enough to move the hinges if desired, but the door

is held in place. Center the door in the opening. Next level the top hinge plate and tighten the screws. Finally, level the lower hinge plate and tighten the screws.

g – REPLACING THE GASKETS
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 center from both ends by gently hitting witha mallet until the gasket is completely seated in place ( see figure 14 for proper gasket placement).

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

CONTROL BASICS

Your new Centerline Refrigerator or Freezer is equipped with a digital control, which precisely regulates operation. It is supplied from the factory completely ready for use.

a – INFORMATION MENU

The information available in this menu is:

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

Access to menu and information displayed:

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

Initiate Stand-By:
Keeping the button pressed for 3 seconds allows the controller to be put on a 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 keypad, adjust setting so that LOC = NO.

b – ADJUSTING CABINET SETPOINT Setpoint display and modification:

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

c – 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. In stand-by, the accumulated time count is frozen

Manual or remote defrost start:

It’s possible to manually start a defrost, by pressing button for 2 seconds.
Defrost type. Once defrost has started, 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.

c – INITIATING A DEFROST (cont’d)

Resuming thermostatic cycle:

When defrost is over, if DRN is greater than 0, all outputs will remain off for DRN minutes, in order 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.

d – CONFIGURATION PARAMETERS

Parameter Configuration:

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