II. RECEIPT INSPECTION III. INSTALLATION (continued)

II. a - 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 led immediately. If

damage is subsequently noted during or immediately after

installation, contact the respective carrier and le a freight

claim. Under no condition may a damaged unit be returned

to Traulsen without rst obtaining written permission (return

authorization). You may contact Traulsen customer care at

[phone] and select option 2 to request a return.

III. INSTALLATION

III. 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.

III. 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, rst if at all possible, we

suggest that the cabinet remain bolted to the pallet during

all transportation to the point of nal 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.

III. 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 rmly into
the cabinet bottom at each corner (see gure 1). For levelling,

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, rst raise and block the cabinet
a minimum of 7” from the oor. For installing legs, thread the
legs into the threaded holes on the bottom of the cabinet (see
gure 2). Be certain that all legs are tightly secured. When
the unit is set in its nal 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.

III. INSTALLATION (continued)

III. d - INSTALLING DRAIN PAN

Centerline compact models are shipped with the drain pan
wrapped up and stored inside the unit.

Remove the drain 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 gure 2).

III. 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.

III. 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 local

electrical codes. Use qualied 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).

Fig. 2

III. 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.

III. 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 ow. There are no clearance requirements for

the sides or rear.

Fig. 3

III. INSTALLATION (continued)

III. i - CUTTING BOARD ASSEMBLY

On prep tables and mega top tables, the cutting board may
require 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 gure 4).
The cutting board is eld reversible, reverse process to

reverse cutting board.

III. 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:

Fig. 5

1. Install backsplash as shown in gure 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.

IV. OPERATION V. OPERATION

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

IV. a - OPERATION DISPLAY INDICATORS

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

IV. 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.

IV. 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 gure 6).

Fig. 6

IV. c - FREEZERS (cont’d)

The electric heaters (attached to the evaporator coil and

drip pan) are energized. When the temperature sensor

afxed 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 rst). After

completion, the total refrigeration system operation is then

resumed. During defrost operation, heat is conned to the
coil enclosure to prevent any signicant 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 rst consulting the factory.

IV. d -

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.

PREP TABLE & MEGA TOP REFRIGERATOR

IV. 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.

V. CARE & MAINTENANCE

DISCONNECT ELECTRICAL POWER SUPPLY

BEFORE CLEANING ANY PARTS OF THE UNIT.

V. 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.

V. 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 ttings are removable without tools

to facilitate cleaning.Depending on the level of cleaning,

drawer model interior ttings may require a tool to facilitate

cleaning. The drawer frame may be removed without tools.

Fig. 9

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.

V. c - 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.

V. d -

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 ushed with fresh water by
a qualied 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

V. e - DOOR RE-HINGING

The door(s) on all compact models can be easily re-hinged
in the eld. 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 deparment (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.

CONDENSATE REMOVAL SYSTEM CARE

V. e - DOOR RE-HINGING (cont’d)

Carefully lay the door down on a padded at 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 rm 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.

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.

PREPARING FOR EXTENDED SHUTDOWN

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.

VI. a - INFORMATION MENU

The information available in this menu is:

* displayed only if enabled (see Conguration 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).

-8-

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.

VI. b - ADJUSTING CABINET SETPOINT

Setpoint display and modication:

• Press button for atleast 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.

VI. CONTROL BASICS (continued)

VI. 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

inuenced 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.

VI. 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.

VI. d - CONFIGURATION PARAMETERS

Parameter Conguration:

• To get access to the parameter conguration menu,

press button and for 5 seconds.

• With button or select the parameter to be

modied.

• 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.

TRAULSEN EQUIPMENT WARRANTY

v. 100215

P/N 375-60359-00 (REV. B)

VIII. d - WARRANTY STATEMENT:

For sales of Traulsen refrigeration equipment (“Equipment”) within the United States, Traulsen warrants to the original
purchaser of the Equipment (“Purchaser”) that Traulsen will convey the Equipment free and clear of all liens, security
interests, and encumbrances created by, through or under Traulsen. Traulsen further warrants that for a period of three (3)
years from the later of either (a) the date of delivery to the common carrier or (b) the date of installation (the “Domestic
Warranty Period”) but in no event, shall the Domestic Warranty Period commence later than 3 months from the date of
delivery to the common carrier unless otherwise agreed upon by the parties in writing, under normal use and given proper
installation and maintenance as determined by Traulsen, the Equipment: (a) will conform to the specifications as provided
by Traulsen (“Specifications”) and (b) will be free from substantial defects in material and workmanship.

The warranty period for compressors shall extend for an additional two (2) years beyond the Domestic Warranty Period. In
the case of a nonconforming compressor, Traulsen shall provide a replacement compressor; however, all installation,
recharging, and repair costs shall be the responsibility of Purchaser. In the case of a nonconforming part, Purchaser must
return the part to Traulsen within 30 days from the date of repair. Failure to return a claimed defective part to Traulsen
within the 30 days will waive the right to the warranty claim.

Additionally, Traulsen provides a lifetime warranty on the housing of cam-lift hinges and the workflow handles. In the case
of a non-conforming housing for cam-lift hinge or workflow handle, Traulsen shall provide a replacement part; however,
Purchaser shall be responsible for any other replacement costs, including but not limited to installation and labor.

The Domestic Warranty does not apply to: (a) consumable components or ordinary wear items; (b) components that are
removable without the use of tools including but not limited to gaskets, shelf pins, and light bulbs; (c) use of the Equipment
components or parts not supplied by Traulsen or specified by Traulsen in the Operator’s Manual as set forth on Traulsen’s
website; or (d) damage resulting from fire, water, burglary, accident, abuse, misuse, transit, acts of God, terrorism, power
surges, improper installation, or repairs or installation by unauthorized third parties. Additionally, the Equipment is intended
only for commercial use and should not be used by consumers or households or in any non-commercial application. This
Domestic Warranty does not apply to, and shall not cover, any Equipment that is installed or used in any way in any
residential or non-commercial application. No warranties, express or implied, are provided to any residential, consumer or
non-commercial purchaser or owner of the Equipment.

For Traulsen units purchased for use with a condenser provided by a third-party,
those components contained within the unit to the point of connection of the refrigeration lines leading to the third-party
condenser.

In the event of a breach of the warranties set forth above (the “Domestic Warranty”), Traulsen will, at Traulsen’s option and
as Purchaser’s sole remedy, repair or replace, including labor costs, any nonconforming Equipment, provided that (a) during
the Warranty Period Traulsen is promptly notified in writing upon discovery of the nonconformance with a detailed
explanation of any alleged deficiencies; (b) Traulsen is given a reasonable opportunity to investigate all claims; and (c)
Traulsen’s examination of any alleged defective part confirms such alleged deficiencies and that the deficiencies were not
caused by misuse, neglect, improper installation, unauthorized alteration or repair or improper testing. Traulsen reserves the
right to, at its request, require Purchaser shall ship the alleged defective part to Traulsen for inspection and confirmation of
defect. No Equipment may be returned without Traulsen’s approval.

Purchaser is solely responsible for determining if Equipment is fit for a particular purpose and suitable for Purchaser’s
application. Accordingly, and due to the nature and manner of Traulsen’s Equipment, Traulsen is not responsible for
the results or consequences of use, misuse, or application of its Equipment.

THIS DOMESTIC WARRANTY SETS FORTH THE EXTENT OF TRAULSEN’S LIABILITY FOR SALES WITHIN
THE UNITED STATES. EXCEPT AS SET FORTH ABOVE, TRAULSEN MAKES NO WARRANTY OR
REPRESENTATION OF ANY KIND, EXPRESS OR IMPLIED (INCLUDING NO WARRANTY OF
MERCHANTABILITY OR FITNESS FOR ANY PARTICULAR PURPOSE). IN NO EVENT WILL TRAULSEN’S
LIABILITY IN CONNECTION WITH THE AGREEMENT OR SALE OF THE EQUIPMENT EXCEED THE
PURCHASE PRICE OF THE EQUIPMENT AS TO WHICH THE CLAIM IS MADE. IN NO EVENT SHALL
TRAULSEN BE LIABLE FOR ANY LOSS OF USE, LOSS OF PRODUCT, LOSS OF PROFIT, OR ANY OTHER
INDIRECT, INCIDENTAL, SPECIAL, OR CONSEQUENTIAL DAMAGES RESULTING FROM THIS WARRANTY
EVEN IF TRAULSEN HAS BEEN NOTIFIED OF THE POSSIBILITY OF SUCH DAMAGES.
